MobilizeThis 2008

A short excerpt from an email I fired off this morning;

Hi,

I consider as both a part time TAFE NSW employee and consultant in the field that Diigo is an invaluable tool for communicating with teams and individual teachers.

I output my Diigo tagging into Twitter so effectively I’m NOT dating only sharing my discoveries of good educational resources or events.

I also emulate my Diigo tags in del.icio.us effectively NOT dating but sharing again and connecting core business potential with my networks there also.

My Diigo and del.icious outputs alert me via email when others have added resources to my groups.

very handy and timely seeing as I’m chained to this p-2-p time waster call email.

I am MARRIED.

The sooner we have a a database of ethically enhanced employee profiling then the sooner we can actually do business as it is being done in the millenium we live in.

:)

ps.  I urge you to consider sending me an email that self-nominates you for a Presenter role at MobilizeThis2008 - http://mobilizethis.wikispaces.com

Your theme - send me it via email.
Your timing - somewhere between 22 - 24 th October
Online - straight from your desktop
Networked - check out the other presenters
Free - as in freedom

Perhaps your theme could be ‘Using Social NETWORKING Tools for Educational Purpose’

Can an iPhone be an educational tool?

As with all new technology, there are those who are hailing the new iPhone as a technological breakthrough that will have a huge impact on education.

Here are some articles to consider

For those who haven’t yet managed to play with one, it is probably hard to understand what the iPhone actually does.

The Apple iPhone site.

There are some Youtube videos that might be useful

Perhaps the most daunting aspect is the upfront cost of purchasing one.
This may mean that it is a long way from becoming the mobile technology of choice in educational institutions.

And then communities are beginning to talk about the “hidden” costs.

But, if you have an iPhone, is it the educational technology of the future? I’d love to hear what you think.

Beyond Essays: Web 2.1 and the World of the Multimedia Collage

Summary of a talk given by Jason Ohler at the Desire2Learn Fusion 2008 conference.

Miss Phelps was my favorite teacher ever. She was one of those magical teachers who can hear students knocking on every door. You know, many teahcres say, you can't go through that door, we're all going through this door. But she understood, and found a way, for you to learn the way you want to learn. I remember, she got me to learn the names of the dinosaurs by telling stories about them. Or my grade ten music teacher. I was in a rock & roll band. I could hear music, but I couldn't read music. You had to be able to read music to be in the course. But he let me in.

Our kids these days are banging on the door. They have iPods and video and the rest. They want to show you what they know. But they can't show you unless you open that door. To me, teaching is being a door opener. The rest is well-intentioned paperwork.

Look at today. 25 years ago this was Star Trek. We create original music for our phones. No matter what the technology, we will create with it. It's not just a communication device. It's an easel. Using two devices at once! 'Screasels'. Not just screens, but easels. This is where they go to paint.

Literacy means producing and consuming the mdia forms of he day, whatever they are. Which just so happen to have been, basically, words on a screen. But that's just not the case any more. The media are today are so varied - you go to slideshare, you go to YouTibe. They're varied. And students need to be able to rad and write in these media. And they need to write. If they just produce, if they don't consume, they become victims of media. Kids need to be able to writ whatever it is they read.

Literacy has shifted. We had words when we were in college. This was up to just a few years ago, as recently as five years ago. That's when it becme very easy to produce media. The multimedia collage is the new baseline media. Images, text, movies, animation, music - and the abiliy to put all those together.

Why is literacy changing? The 'read-only' to 'write-possible' time is shrinking. For text, it took thousands of years. Moving pictures, about 100 years. Web, about 15 years. To the point where, as soon as something is created, we will be able not only to consume it, but to write with it at the same time. Not only that: the tools are cheap. And there are free stages everywhere, free art and story environments.

When kids go into the story environment, their sense of quality goes through the rood. That's because of the tEcosystem - the tech ecosystem. Remember when it was tapes and 8-track and vynal? Not it's computers and cameras and video.

Web 1.0 - 1990- 2005. You had very few people generating content, and the rest of us would read it. You needed to know HTML (and have no social life). Now everybody can play. Everybody becomes a client and a comoytrer at the same time. Then there's Web 2.1, which I call read-write-paint.

But the big change that's coming is the semantic web, web 3.0. It will be a while yet. What it does is that it takes web 2.1 and it puts it into the contextual model of a brain - everything is related to everything else. We 3.0 goes out, collapses Googles million search results, and relates it to everything you know, everything about you. It's the only way to deal with all this information.

6 Mantras

- Go from text-centrism to the new media collage

- art is the 4th or the next R - you need to use th pencil, and you need to be able to use photoshop. Multimedia collage is the next Esperanto - that's how we are able to navigate a Chinese web site. Creating art today is rel work for real pay. ISTE is on board - their new standards require 'innovation and creativity', first and foremost. And the easiest way around copyright is to have kids create their own stuff.

- the DAOW of literacy. Digital, Art, Oral, and Written.

- attitude is the new aptitude. Practice zen-tech, not zantech. Evaluate everything. Be critical. Everything changes. Don't ttry to hold on to things, to control things. Put the tools into the hands of the kids.

(number 5 was skipped)

- story is the resonant info-schema. A kid using a green screen to put erself into a story using her own artwork. Do kids love this? Oh my yes. I haven't found one person who realy doesn't want to tell their story. It is not about high-end gear and lots and lots of time. I can work with any technology - generally whatever I do with students is all free to them. Money is no longer a barrier. The rule of 80-20 -- they could produce 80 percent of the content in 20 percent of the time, and spent the rest of the time tweaking. And it's all about the story first, and the technology second (what happens when you give a bad guitar player a bigger amplifier?). If you have a weak story and commit it to multimedia, that only makes it worse.

Teachers are more important than ever. We need to be the guide on the side, and not the technician magician. When I go into a class, I ask who has a digital camera? Who has expertise in...? I made a catalogue of the resources I have to work with. Then I set up a scenario. This class is a senior seminar. It's a tavern. It's a hallway. It defines the sort of bhaviour that's allowable in the environment. (Great point! - SD) And then they create media (which they will do with or without us).

Assessment - we need to get away from the 'give an A to anything that moves' syndrome (that's where, you see the screen, if something moves, it's an A, because we're afraid of the tech, we don't know what's good or bad). We have to get past that. My book (Ohler's book) describes the things we can look for in order to assess this stuff. Everything that it took a kit to get up to the media is assessable - the writing, the planning, the research. Not just the stuff that's on the screen. You have a portfolio in front of you, a whole range of skills.

And you need to be clear: do you want the work to be clear like an essay, or challenging like a poem (it's a slider on a continuum). Documentaries need to be clear. But poems can be complex and challenging. My book: I decided to wriet a story instead of just another academic tome. Why is the story important? because a month later, you will be able to tell the stry. You will be able to remember it.

The core of stories: stories need a problem and a solution, and tension in the resolution of that. There has to be a transformation - a change, a growth. If you don't have a transformation, you have an average WWII movie (bad people, shoot them). Inquiry, discovery, learning. It's that simple. (Which is diametrically opposed to No Child Left Behind). It's the new you, who must change, and the old you, who doesn't want to change. Kieran Egan (SFU) - when students say "I don't get it" they;re really saying "where's the story?"

Kids come to school versed in the story form. But we tend to give them list-oriented information. There is no change, no tansformation. The opposit of a story is a vacation slide-show. Where is the transformation? (8 levels of stories - he blasted through this). There's the R word - I need to know, what does the character realize? Show me that they're a different person now. Bloom;s taxonomy is a great way to judge how effective a student's story is.

2 rules of media literacy:
- give people a question - you want people leaning forward, watching
- watch it three times, so you can see beind the story

(Demo of 4th graders' movies)
What made the video work: they culd have just shown how to roll the ball, but they didn't - they tried, and it didn't work, so they had to figure it out.

(Another movie)
Notice how the student didn't say "um" or "ah"? That is the norm. When they are immersed in their own story, they don't stutter at all.

(Another video)
Notice that in all cases we do not have tremendously high production values, and who cares? We are now at the point where if we are willing to live with some rough edges we are able to get the same kind of work, the same kind of prepapration and devlopment, in the same time, that we might with an essay.

The process I use is this: I don't use a story-board. All a story-board will do is ensure that your very boring story flows. So what I do is to use a story map that charts out the emotional flow (instead of the flow of motion) itself. Problem-Solution. Beginning, transformation, end. Then I have storytellers peer-pitch it. Just like hollywood. Because this catches the weaknesses, it changes things. The arc is a story map I use a lot. An arc of transformation, an arc of events. You need both.

The media development process. Planning, pre-production, production, post-production, delivery. Story creation process. Record it - an amazing and magical thing happens when people hear their own voice - when they hear themselves speak their own writing they themselves will go in and fix it.

The big picture: stories are dangerous. We know that we have witnessed a good story when we look up and say "I g=forgot I was there." What is the role of critical thinking when you are effectively hypnotized. That is the new frontier - wondering about how we do that. Because that is what we must do.

Don't rule by concerns. One person says "I ahve a concern" and everything stops. The problem is, thyere is nothing you you can do with it. Take a concern and turn it into a goal. Concerns are just negatively stated goals.

Forms, grammar - I can show you examples. I have them write in what I call 'visually differentiated text'. Vs. the essay form. I can't gt a visual toe-hold on the essay form. But they will read the nicely presented form.

Digital makeup. I don't like videoconferencing. I like audio conferencing. I put it on mute and lift weights. Anyhow, video - we will have video makeup filters.

Go tell your story.

Exploration of an Inegrated Media Tool

This was a great talk by Greyson Purcell outlining a simple but powerful video uploading and playback system integrated into D2L.

YouTube convinced our instructors that uploads should be easy, so...

[demo of UI video uploader site]

Why?

Process before the tool:
- faculty contacts us directly
- we train faculty to encode video
- we set up password rights in ActiveDirectory)
- we sent sample HTML instructions
- faculty encodes files, uploads files, enters HTML into ICON (the local D2L installation)

Problem: encoding
A standard encoding of a lecture is about 500 kbps, which means a 50 minute lecture is 180 mb. But faculty would encode at 5000 mbps, resulting in files that were far too large to manage

Problem: HTML
Complex HTML encoding "It was a complete failure"

Plus: we basically had no way to get student material to the web. We basically had students give it to faculty members.


What?

Simple video file conversion.

ffmpeg - is a simple server-based encoding tool. http://ffmpeg.mplayerhq.hu/
Sample command: ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x240 video.flv

On the web there's tons of materials on how to use this software. Eg. at vexxblog (How to convert/encode files to FLV and how to install ffmpeg )

So we set this up, attached it to some D2L code that captured the student's name, course, role, etc. This created simple upload and display screens for students.

We also wanted to have a nice palyer for the videos. Flash player with features for things ike full screen, popup menu, etc. We also added a comment system (because it uses the D2L login, you can't spoof comments).

Also: we can convert videos to podcasts - ffmpeg supports a variety of formats. We can convert the web based player into a podcast manager too and distribute videos via iTunes.


Pedagogy

Now it's in the hands of faculty. We're going out into this beta period, and we'll see what happens.

We're gtting rid of a hurdle - us - and opening the floodgates. How many videos will people upload? What will the time frame be, will there be a massive rush? How many servers do we need? Do we make this on by default? What about copyright issues?

More Stuff

Also - direct recording from video camera... could be done with Flash media server.

Ability to hide the video, or any way to mix and match rights to edit, access, etc.

Files can be stored as files on a normal web server, or can be streamed using a Flash media server.

Comments could be tied to video time - so when you click on the comment, the video advances to the time.

This I found interesting from Greg Whitbys YouTube. Talking about changing the system through three pressure points. It made me think that the perception gap between what ‘administrators’ are doing and teachers are ‘doing’ is out of alignment with what I’ve been hearing in Online sessions the last few weeks. I especially like the comments about the strategy to put ‘mentors’ in schools to help develop teachers and support them. This would give a clear indication to the classroom teacher that they are connected to policy directors - often people that we never meet. On the the other hand, I think that there are now so many teachers doing amazing things in their classrooms that their line managers do not know about, so they may be pleasantly suprised when this alignment takes place. I hope that this message and approach is adopted - getting mentors into classrooms to train, support and deliver is a critical link - not just as one off PD, but ongoing support with regualar follow ups.

One of the great strengths of the New Tech Foundation (PBL) is that school teachers in that ‘network’ have IM access to each other, and more importantly to mentors and senior foundation staff.

I don’t think that we are there yet in terms of transparent communication between teacher, mentor and executive - but this video points to the fact that it’s on the agenda, which is great!

Reading this article about Twitter made my head hurt just a little less.

The story of how Twitter took off reflects how web 2.0 tools are taking off!

Twitter has become so popular, so fast, that keeping up with its fast-growing user base is a real issue. So many people now use Twitter to update friends that the system often crashes. Twitterers, as they call themselves, post their updates at Twitter.com or by using text- or instant-message tools. The service is even credited with breaking news about fires and other natural disasters.The service is even credited with breaking news about fires and other natural disasters.

So for some, Twitter has been a lifesaver in the whole sea of virtual information. I’m finding that there is just so much information available, at such pace, from so many people…well to be honest, my head hurts a lot! When I started out blogging, social networking was easygoing, a friendly bit of patter with superb points of connection.

Now there is almost to much, and I sense a competitive edge that is not in keeping with that easygoing social networking kind of way of learning. It’s no longer about what the latest tool is, but how many of the seemingly vital tools YOU are using otherwise otherwise you are not really funky Web 2.0!

I am having to prune down rather than add to my toolkit. Too many Ning groups, too many flash meetings, too many points of connection. I am certainly over that initial flush of tool grabbing. I use what I need. I read about the rest, and when I need a way of thinking or connecting for my students, I’ll integrate that. After all, we should be focusing on shifts in thinking, not shifts in technology tools. Too often the shift is about a toy tool, not about substantially different pedagogy. Unfortunately, the reality is that we can’t substantially shift pedagogy on our own, or easily, unless we have a whole-school approach to change. That’s where a school approach wins hands down - the most creative, immersive and best example I have seen of this has been the work the Lenva Shearing is doing at Bucklands Beach. Lenva, you are a dynamo, and an awesome example to us all.

So you know what? I’m over the initial flush of social networking.

Why?

Because more and more networks and social connections are being created and maybe, for me at least, there are too many. So I have to be very particular about what I choose and what I follow - and more importantly - WHY! I have a very busy day job that takes me into the night with all my networking and creative planning for change.

Interestingly these concepts were raised in the backchannel of the excellent Knowledge Conference Key Note presentation by Steve Hargadon on “Web 2.0 is the future of education”. (Congratulations to the organisers for a great conference!)

While we are busy social networking, collaborating, and creating a shared language, I believe we are also beginning to fragment the conversation. The culture of participation is pervasive, and even invasive. I love it and I hate it. I enjoy it and am frustrated by it. The teacher librarians in the back channel reflected on the explosion of information that Steve talked about. No solutions, just ideas. An excellent session for my staff to attend.

My personal focus is staying apace with 3D and the metaverse - simply because this is the new frontier and I want to understand it’s potential for learning and teaching - and life! I can’t ‘talk’ or network with everybody. For now, the group of educators involved with Second Life and the like is sufficiently small for me not to have infobabble in my head!

I’ve been in a few online sessions recently, and one of the questions that teachers who have figured out what Web2.0 is in comparison to using regular unleaded, is this. “I want to start blogging with my students - how should I start?.

Right up front, let me say that if you are going to start blogging - in a school which has little idea what blogging is, then stop. Turn around, drop the term ‘blogging’ and just call it something like a ’study group’ or even an ‘e-study group’. That will keep you off the radar, it won’t add new language to the kids - who don’t call MySpace or BeBo - blogging.

It’s just that you are using ICT as your job says you have to. You’re not putting yourself out there as some crusader. Trust me, you’ll be glad you did later.

Next up, recognise that you are not starting ‘blogging’, you are starting ‘reflective’ writing in a collaborative setting that just happens to be online.

Given a choice, I’d hook this up to Literacy and Curriculum rather than ICT. Sure it uses a computer, but then what doesn’t these days. A community blog is the most efficient, instant, flexible and accessible way for a teacher to get around a class of kids; see what they are doing; thinking; who is talking with whom, who is leading whom etc., You simply can’t do this with paper! The nearsest you might get is trying to listen in on hallway conversations - but thats creepy.

Kids will comment, talk about stuff, ask questions online that they won’t in the classroom. Some of the least vocal kids in your classroom are most vocal online - if you build a sustainable ecosystem.

You do have to work on scaffolding their comments into the context of the topic, you just can’t predict what they are going to be. Ah, I just said it wasn’t hard - correction, tick off answers 1 through 10 from text book is easier as it requires far less thinking on the part of the students or the teacher. So for those teachers who hand out the low order thinking stuff (tick a box, ABC stuff) then this is going to be work, sorry.

There is a place for formal assessment. The quick test is a great way of ‘oil dipping’ to see if there is content learning happening. But is should not be the major ‘norm’ in your assessment methods, and in no way summises the learning that is happing. You might have a kid with an awesome video-blog, who stuggles on the test. Remember in 21C learning - students are developing ePortfolios and ‘online identity’ so at least now, that students measure in not just the test score!

It also takes far LESS time to do than collecting books, marking (B+ is not developing the learner) and handing them back. Those who say ‘I don’t have the time’ - are basing that assumption on their personal experiences of the past. Ignore them. The only previous ICT they needed to learn in the last 15 years has been Power Point, so they know what they are talking out - grrr.

Its conversational writing - the blog posts will usually be ‘formal’, but the comments will be a hybrid of txt and formal - and thats just fine. It’s conversational language - as language is always evolving. What we as teachers are interested in - is the learning and the use of the language. If a few *lols appear, don’t worry, it’s not a bad thing.

So here’s a quick method that I suggest those who want to start ‘blogging’ have a look at. I am suggesting that you DONT create individual blogs for students, but use a COMMUNITY blog - I use Ning, but others use 21 Classes. See why suits you. But it’s NOT THE TOOL that matters, its the ecosystem you are creating.

Heres the presentation, but don’t forget to read the other stuff under it too!

Also, don’t start the lesson with ‘today we are going to start on online creepy treehouse’! -Start by getting them fired up. Start by offering them the opportunity to have input on their learning. A nice big fat discussion. It might take you a week to get the discussion to the point where they identify that their ‘could’ so amazing things if they had (x/y/z). That time is well invested. It creates buy in and give you about 30 advocates who will be amazingly vocal in other classes over time, so you won’t have to

Build your community in your classroom - it will soon spill out into the hallway and down the corridor. Its far easier to start there that trying to convince staff that your ideas are something to agree with (initially).

Understanding the Surge - 'Winning' the War on Credit

Perhaps it's because I am in the U.S., but I am being flooded with quotations from John McCain declaring that if the U.S. had followed Obama's path (or withdrawing from Iraq) the U.S. would have 'lost' the war.

This is patently ridiculous. Any problems to American security were the result of the war, and not prevented by it. The U.S. would have 'won' (by any contemporary definition) by never having had invaded Iraq in the first place.

Moreover, insofar as the purported purpose of the war was to remove Saddam Hussein and to eliminate WMDs, then the war was 'won', by any definition, in the first few weeks of the conflict. Subsequent problems - such as the dangerous destabilization of the region, and the widening influence of Iran (which McCain) cites, were caused by the war, not prevented by the war.

But let's suppose none of that applies. Lets suppose that 'winning' the war means something like bringing order to Iraq, keeping the peace, and facilitating the transfer of power to Iraq. Then you could say that the surge is working, couldn't you?

Well - no.

What the surge is doing is obtaining military results on credit. It is extending U.S. military commitment beyond its ordinary capacity, requiring stop-loss and other extraordinary measures. The surge is something that cannot be sustained long-term. It creates short-term gains, and the illusion of winning. But people hostile to the U.S. - people like Muqtada al-Sadr, for example - simply bide their time and wait for the U.S. to exhaust itself.

Meanwhile, Iraq is still not safe, and - as Obama points out - the U.S. lack resources to deal with other significant issues - things like, say, the occupation of Afghanistan, or any domestic emergency on the scale of Hurricane Katrina.

There is no success here. To say that the war is currently being won is an out-and-out lie. The only way the U.S. can maintain even a semblance of control in Iraq - and maintain those oil supplies - is to maintain a larger troop commitment than it can sustain. It is living on borrowed time. The American people are being sold a sham victory on credit.

A better plan? Get out of Iraq, and spend the trillion dollars instead on energy independence and national infrastructure.

Intgrating iTunes U Access into Desire2Learn

Summary of a presentation from David Delgado, University of Wisconsin-Whitewater, at the Desiore2Learn Fusion 2008 conference.

UW-Whitewater - has an established culture around D2L, which was adopted in 2003, with 1000 course sestions. A podcasting service was already established when iTunes U first became available.

What is iTune U? It's an Apple initiative to support educational institutions. It offers free storage space that campuses can use - you sign a service license, and Apple provides documentation and consulting service. The documentation in May, 2006, was lacking, but that has improved since then, and discussion forums are filling out.

People actually preferred our existing podcast service over iTines. They didn't know the iTines interface. And also, we were able to support our own service better, because we had more control over it.

Basically, Apple offers storage space. The podcasts can only be accessed using iTines software. iTunes U access is dependent on campus LDAP authentication. It is up to the campus to make that link independently, and Apple is only starting to offer consultation. Basically, you set up a web board that contacts your LDAP and then decides what to tell Apple's iTunes service.

We had to write the authentication script in order to provide access. We didn't have gthe course information it needs built into LDAP, but we took our existing podcasting service and used that to povide access. So now we have a screen that shows iTiunes and local podcasts. We use a PHP class to handle authentication. http://omega1.uww.edu/itunesu

Student Access: D2L information can be used. We use the course offering ID as a course identifier, and plug that into the script. Access is available inside a D2L course as a Javascriopt widget. There is also a publicly accessible area, http://itunes.uww.edu

Issues to consider:

- iTunes access in general access labs - iTunes was designed for personal access. We map each person's personal files to whatever machine they're logged into, so they get their own iTunes bookmarks.

- Moreover, it does not meet accessibility standards. There is a very hacked version of iTunes, provided by EASI, which is supposed to offer accessible use.

- Portable devices aren't as accessible to our students as we thought. We have a significant graducate population, and a significant distance population. Most of our students listen to podcasts on the computer. It really differs based on the generation.

- Student podcasts - are becoming an increasingly important practice. But our original configuration did not allow students access to the site; so we had to change that.

The Future:

It will continue to co-exist with the local service - some instructors prefer our service because it's more available to them. We are working on an API that allows us to upload direcly from our own podcast page.

Also, we want to modify the D2L widget using Flash to improve security. Because it uses JS, the credentials can be sleuthed. But we can use Flash to hide the authentication credentials.

And finally - we are looking at a Podcast Producer pilot. This is a hardware-software combination build off a Mac OS server that allows many connections from different machines, and it will capture the frames from the computer being used at the time, and processes it into video and uploads it to the iTunes U website. We are looking at having a camera attached to this, recording the speaker until they use the mouse.

The key to all of this is D2L and the database - we take the information from the database and send it over, and it works. It just works.

(Contact the speaker for scripts and widget code).

Virtualization and Desire2Learn

Summary of a talk by D2L's Brett Emmerton at the D2L Fusion 2008 conference. The talk was quite technical, and so is this summary, but the concept of virtualization is one that should be understood by those seeking to know where computer environments are going in the future.

Virtualization

Each virtual machine is a complete system encapsulated in a set of software files. The purpose is to take advantage of unused cycles in servers. So you can run multiple 'machines' on top of a single server. The virtual machines run on top of what is called an 'ESX Server' which in turn runs on one or more physical servers. It allows you to share CPU cycles, shae memory, share local disks (eg. SAN (Storage-Area Network) based systems).

Some terms:
VM Host - is the physical server that VM Ware is installed in
VMs - are the virtual machines

We virtualize all layers - not just individual machines, but storage and network layers as well, using DRS (Dynamic Resource Sharing). The servers get moved around to the physical host depending on resource usage and availability.

Uses

1. VCB - VMWare Consolidated Backup - we capture a snapshot of the virtual machine and store it - it is essentially a machine, ready to roll. This snapshot basically clones the existing machine. But in order to take that snapshot, you have to have another Core and RAM ready to take the snapshot - so you have to watch your resource allocation. Also - snapshots can be 'left open' and it continues to write - people sometimes forget to close off snapshots, which will use a lot of storage.

2. Virtualization as a resource multiplier: even with peak load spikes, we are using less than 10 percent of the capacity of our application servers. So, instead, use (say) a 4-way server and run 32 virtual machines on it. Or to share memory - or to 'decay' unused processes that are occupying memory.

3. Interoperability. We can apply the VM hypervisor across all the layers - so it doesn't care whether it's an HP box, a Dell box, or a Sun box. You can order the boxes with the VMWare pre-installed - just tell them what your license is, and you can run your machine. Or., eg. we were able to deploy eight new application servers on a network in just a few minutes.

4. Resource Pools - aggegate collections of disparate hardware resources into unified logical resource pools, creating addressable agregate resourcing. This means, eg., that a failed server doesn't mean a faled application.

5. Add hardware dynamically. Provisioning is 'fire and forget'. You can easily add more capacity. You can also allow the VMWare to manage the load - dynamically balancing the load across the servers.

6. Policy Enforcement (was mmtioned in passing, not as a separate slide).

7. HA - High Availability - is an automatic restart engine. One server may be down, and unable to access its disk image. Other servers can see the disk image, though, and can restart the server based on policies set within the organization.

Preferred VM Configuration

1. As many CPU cores as possible - license VMWare by socket, which enables larger vSMP configurations and allows you to plan for VMotion compatibility (get a bunch of alike servers to prepare for this).

2 Maximize memory. Be careful, high density memory is very expensive - it's often cheaper to buy more servers with more memory. And more servers are better for redundancy anyways.

3. Fast storage means a wickedly fast server VM. You have to have high-speed storage. What am I excited about? Solid state disck.

4. 24-Hour+ Burn-in, because most failures occur in the first 90 days. memory is the part that fails the most. So you esnt to do a memory burn-in.

5. No single point of falure. Local recovery/failure is always preferred. Have someone - even a non-techie person - review your configuration (tell them what it is) and ask questions.
- NICs - two teams of two - so you have separate controllers
- separate admin and management and VM data traffic physically
- redum=ndant switch, network and storage layers
- redundant fans, power supplies (often people overlook the basic pieces)

6. We prefer fault tolerance to load balancing

7. Network load-balancing

8. Storage load balancing

Overconfiguaration of VMs

This is where I see things going wrong.

1. Physical to Virtual configuration (P2V) is efficient, etc., but you can run into problems with co-scheduling, and load optimization takes time.


Storage Configuration

- typically we use 10-20 VMs per LUN
- allocate the fastest disk and storage connections to the LUNS hosting your Virtual Machine DK files

Naming Standards

Apply naming standards to distinguish:
- SAN vs Local
- test vs production
- RAID type
- LUN ID
Have a central list, know why you're using it, know who owns it.

Other

- Make sure your CD-ROM isn't connected on Power-On if you don't need it
- Do not leave open snapshots on production machines
etc

Connectives and Collectives: Learning Alone, Together

Summary of George Siemens's opening keynote at the D2L Fusion conference in Memphis. It represents, in my view, a substantial development in his thought.

box - Dabbawala - one who carries the box. This is a network of people who collect and distribute in excess of 200,000 meals a day in Mumbai.

encyclopedia - Wikipedia.

news site - Ohmynews.

marketplace - Seekers, solvers and a marketplace.

MIT Center for Collectove Intelligence: how can people be connected in order to work collectively?

Don't fight the internet. Don't fight human nature.

In most colective and collaborative activities, human nature is overlooked. For example, 'wearesmarter' tried to get people to collaborate to write a textbook. But people don't want to be submerged in a project like that.

The basis os any collective activity is the self.

- the brain is physical and confined; but the mind is flexible, the mind is external (you rely on external thoughts, external reminders). The mind is social.

- The individual mind *must* communicate - to connect, to form relations.

- our ability to speak is in essence a way to externalize the self. Language is a tool to demystify myth - we make it clear and understand.

- at its core, language is a social function (Wittgenstein's box of beetles).

- symbols - 'carriers of previous patterns of reasoning' - reflective of how we thought at one time. Symbols, then, are things we use to externalize ourselves.

Technology as language?

Our concets, then, are help at least partly externally. These are expressed socially, and as socially, are socially shaped. [Image of 'Formula of Concepts'] Example of how we understand the word 'right' in a context. As the context changed the collectively help viewpoint of language, our understanding changed.

Roy Pea: Intelligences are distributed across minds - but also across technologies. Rubber hands (we substitute touch sensation to the rubber hand we see) and bananas (when a monkey eats a banana, or watches another monkey eating a banana, the same area of neurons (mirror neurons) are firing).

Polysensory data: substituting video information with stimulations on teh tongue - we csn replace 'sight' with sensaion. Hence the phenomenon of 'blindsight'. (Paul Bach-y-Rita)

(SD: numerous examples showing the same sort of thing)

We can extend ourselves with tools, with technology, with language, with signals. The mind is enormously robust, enormously plastic.

BUT: our intgration and extension of self involves a preservation of self. (*key point*)

Our notion of self is not just physical, but still also the way we extend ourselves. It isn't created through socialization, but it is shaped, and manifests itself socially.

Connectives maintain an autonomy of self. A mosaic. It's the difference between creating a blog and creating a wiki.

Collectives, hoever, involve a subsumption of self. There is a coercion of a sort. These all involve a complexity of activity that requires the inclusion of many people. Creating an LMS, for example. The identity of many people has been subsumed. In many cases, that's fine, but we need to look at where it's not. Because, after all, innovation is deviation.

We used to assign names to inventions. Bt with contemporary corporatization, we have removed the name from the invention. The iPod should be the 'wePod'. In 75 years, we have gone from the individua to the company to the network as th innovator.

But - this raises issues of freedom and control. At the heart of collaboration and maships and the rest, you are playing with such issues.

Networks can result in complex tasks. Underlying all this is the idea of the network. And the network is based on the idea of the individual.

Look at the continuum of strength by connection: from individual (atoms) to groups (or what Geprge is calling collectives here). Individuals create new ideas, novelty, are diverse. Groups require some sort of normalization, some sort of subsumption of identity.

We need the diversity of opinion. Scott Page: diverse people working together and capitalizing on their indviduality outperform groups of like-minded people.

We say we like diversity, but diversity is a pain. It's the person who says "Wait a miunite, what about...?" who is the pain.

Pedagogical implications:

Three areas of choice:
- degree of agent autonomy
- degree of complexity
- degree of task specialization

When we design learning (and other systems) we have to decide which element to stress. Flying a plane, for example - should we grant the pilot complete autonomy?

These are the three key elements we need to look at when we consider what degree of individual freedom we want. (SD - this is a great point)

Robert Calliou - we need to solve the problem of combining our thinking as individuals to solve the enormous problems - global warming, food shortages, etc...

The impact, thn, starts to be seen in the design o technology. Neil Postman - techn ology has a 'give and take' element. Technology gives, but does it take? Plato: does writing impair our faculty of memory?

The technology we use is embedded with social and political artifacts. But does this hinder technology, or help? It creates a new medium for previously unconnected others to communicate. (haythornewaite)

Downes: to know' something is to be organized in a certain way, to learn is to acquire these particuar organizations.

So - is this learning?
- Core content? Our typical model.
- Core content that is co-created with external experts? That's better.
- Let's also bring in peripheral learners - list members, discussion group members, etc. Creates more diversity of input - we will likely have better quality content.
- Let's distribute the idea of 'faculty' among these diverse groups. Open , external experts, the rest. A very rich, very diverse learning experience.

We have a model where we say that:
- we recognize each learner has to have a unique stance, a unique identity
- we recognize that each learner needs to be connected to others

Vannevar Bush: notion of associative trails of content. They experience content not just how we as experts present it, but from numerous sources, where they jump from one source to another to another - they become critical thinkers.

And we want this, bcausde it isn't the content that makes an education, but rather, th ability to continue to learn more.

Freedom of fragmntation: we used to have our wor presented to us. A newspaper. A book. Today, we have a very fragmented world, where we get our information from many sources. That kind of fragmentation gives us new freedoms and opportunities.

For example: when learning from a tecaher, I wuld typically listen, read sources recommended by, be tested according to, the ideas of the individual who has created the course. A very consolidated whole. But today we have fragmented sources. That allows us to repurpose the ideas.

There is:
- a freedom to fragmentation - to get fragments
- a freedom of fragmentation - to be a fragment - to fragment our own thought in numerous places, sources

(SD: this needs to be clarified)

It's the end of the grand narrative, and the beginning of the personal narative. We create narratives not just persoanly, but in particular contexts.

The downside of fragmentation: overload. Too many sources, too many ideas. Too fragmented, too distributed. So the challenge is now in how to pull things together. Some interesting technologies:

- Twitter - and simple social tools. Gossip and trivial talks is typically viewed as a distraction, but (see Zufecki (Dunbar) 2008 - these are in essence the human version of social grooming in primates.

So, the challenge is: how do we preserve the unique values of connectives and collectives. Eg. how do we retain our ability to focus when, say, reading a book? (I have a rule - read one journal article before reading email).

We need to:
- design for varying levels of connectedness
- value the collective effort (the contribution to the whole) - but - what is the role of the individual in that process? What is the role of the agent?

The need for human sociability outstrips the design of our courses, the design of our institutions. It outstrips the flow of information that goes top to bottom. We need to take into account how the mind can integrate all kionds of sources, with great fluidity. Technology plays a similar role to that of language.

We can really improve the learning of our students if we use D2L effectively. If we encourage them to learn socially, they learn much more than they could from me as a faculty member.

We are now at a point where we ned to say, we now understand enough about the social nature of learning (Vytgotsky, Papert, Seely Brown, Wenger), and we also understand the idea of using technology to connect. We have that unique broth, and we just need to season it. Our institutions are barriers, the design of courses is a barrier.

a box - social and procedural nature of interaction
an encyclopedia - a storehouse
a news site - a flow
a marketplace - a forum of exchange

We need to recognize that 'collective intlligence' is not neutral in and of itself. All of them exist as a network in nature, as a node and a connection. But these all vary in strength and connectedness.

The nature of the connectedness we design into our courses is essentially a power relationship. It is a way of defining who will have what identity, and how. It's why you can't just slap down a wiki and say 'contribute'.

Addressing Indigenous Disadvantage in Cape York - “Fight for Life” (pdf, 14pp)

Listen to the people on the ground who are telling us how bad the situation is in Cape York and other remote indigenous communities

Dr Lara Wieland: Medical Practitioner who has worked for years in Cape York as both a doctor and doing volunteer youth work

Dr Richard Heazlewood: Established Paediatric Outreach Team to Cape York, Torres Strait and Tablelands providing remote paediatric services for over 15 years as well as sitting on SCAN child protection team for the region
For some of these diseases of social disadvantage and the third world, Cape York has the dubious honour of having some of the highest rates in the world.

So much of the damage done and that is being done is intergenerational and potentially permanent and we are faced with a time in history where we believe we have one last opportunity to provide the platforms needed to give Cape York people the choices they are entitled to as human beings....

The following eight areas of suggestions through which to address Indigenous disadvantage in Cape York are a synthesis of Ken Henry's seven platforms for addressing Indigenous disadvantage, the Canadian Aboriginal Horizontal Framework and Dr Richard Heazlewood's 2020 summit submission on an intervention into Cape York communities as all three have a large degree of overlap. It also contains personal thoughts gleaned from observation and thousands of conversations over years with people in Cape York ranging from specialist doctors, principals, elders and police through to parents struggling with alcoholism and children of all ages who speak frankly and honestly from their heart. I have found people's thoughts and hopes and aspirations in private are astonishingly similar across this range.

Colleagues who work closely with Northern Territory (NT) communities have stated that the rhetoric surrounding the NT intervention and it's implementation was damaging and hurtful, disempowering and not well thought out, but the flow of resources and a lot of what has been done has been very positive. Surely there is room for an 'intervention' that is done 'right', that has the sense of urgency and cuts across bureaucratic barriers but without being threatening, hurtful, disempowering and poorly implemented?
  1. Health
  2. Substance abuse
  3. Child protection
  4. Learning
  5. Safe and sustainable communities
  6. Housing
  7. Economic opportunity
  8. Accountability
(far more detail in the full report)

Taking action on the situation in Cape York requires courage, risk-taking, political will and high level leadership as well as ensuring effective implementation on the ground.

Each month that goes past means more lives damaged, often irreparably. If something radical is not done soon, we will be judged far more harshly for this and the effects will be far more damaging and far-reaching than anything that has occurred in generations past

Bloom Clock Project

The Bloom Clock Project is an attempt to create a language for discussing the bloom times of wildflowers and other plants that is neutral in respect to climate, region, and hemisphere. Bloom clocks are kept by gardeners, ecologists, and others to record the time of year different plants are in bloom.

Bloom Clocks are really useful to many people, including garden designers and people with allergies: knowing when wind-pollinated plants bloom can help those with allergies (and the doctors that treat them) helping to predict when pollen will be a problem.

Bloom times can be used as indicators for monitoring changes of local and regional climate, and can provide phenological cues which tell the farmer or gardener when to look out for a certain pest.

If you would like to participate then click here.

If you are looking for someone in the know then SB Johnny seems to be the man to talk to about the project, hes a Wikiversity custodian and an organic farmer and horticulturist by profession.

mental modelling, all the way down

Some of the language of the following quote is mangled (bits missing) but the meaning is still clear:
Education is another area in which the computer scientist has confused form and content, but this time the confusion concerns his professional role. He perceives his principal function to provide programs and machines for use in old and new educational schemes. Well and good, but I believe he has a more complex responsibility–to work out and communicate models of the process of education itself.

In the discussion below, I sketch briefly the viewpoint (developed with Seymour Papert) from which this belief stems. The following statements are typical of our view:

– To help people learn is to help them heads, various kinds of computational models.
– This can best be done by a teacher who has, in his head, a reasonable model of what is in the pupil's head.
– For the same reason the student, when debugging his own models and procedures, should have a model of what he is doing, and must know good debugging techniques, such as how to formulate simple but critical test cases.
– It will help the student to know something about computational models and programming. The idea of debugging [note 2] itself, for example, is a very powerful concept-in contrast to the helplessness promoted by our cultural heritage about gifts, talents, and aptitudes. The latter encourages "I'm not good at this" instead of "How can I make myself better at it?"


These have the sound of common sense, yet they are not among the basic principles of any of the popular educational schemes such as "operant reinforcement," "discovery methods," audio-visual synergism, etc. This is not because educators have ignored the possibility of mental models, but because they simply had no effective way, before the beginning of work on simulation of thought processes, to describe, construct, and test such ideas
- Marvin Minsky, Turing Award Lecture, 1970
Teacher and student mental modelling are rather important, including debugging, and can be facilitated by computers properly used. But this requires a teacher who can both program the computer and understand the importance of mental modelling. If those prerequisites are missing then it's not all that surprising to discover that someone has done a research project showing that "it doesn't work".

scratch resources

This page (teaching children computer programming by using scratch) on kidslike.info contains a number of links to good Scratch resources, the best of which I'll summarise below

1) Programming concepts and skills supported in scratch (pdf) (doc)
What problem solving, project design skills, fundamental ideas about computers and programming, and specific programming concepts does Scratch support (and for the latter does not support)? This is an excellent summary, highly recommended, you need to download for the examples (code snippets) provided too, which are really good. Also note this discussion thread on the Scratch forum about this document, especially the comments by kevin karplus and responses by natalie, the document author, to his suggestions

Scratch supports these Specific Programming Concepts:
sequence, iteration (looping), conditional statements, variables, threads (parallel execution), synchronisation, real-time interaction, boolean logic, random numbers, event handling, user interface design

Scratch does not currently support data structures (arrays, etc.), procedures and functions, recursion, inheritance, defining classes of objects, exception handling, parameter passing and return values, text input, file input/output

2) Scratch Programming Projects
Ten excellent projects described in just the right amount of detail, with requirements and extras:
  1. "Chasing/Eating" (Pac Man Type Game)
  2. Red Light/Green Light
  3. Pong
  4. Target Game
  5. Communication Project
  6. Animation of a short story
  7. Virtual Musical Instrument
  8. Virtual Board Game
  9. Basic Space Target Game
  10. Shape Drawing Robot (Polygon Robot)
3) Shark eats fish
Introductory tutorial, clearly explained with screenshots

4) Comparison of different languages (thread in Scratch forum)
This comment by pkimelma presents a well thought out sequence for teaching Scratch using a games theme.

Other comments in this thread compare Scratch with Phrogram (which has 3D graphics), Alice, Starlogo and others.

5) Kevin and Abe Karplus Scratch page looks to have a nice collection of scratch exemplars

I think its been forever now that I have been saying to drop our internal systems and engage with the real stuff… I wonder if I could stretch the message in this research pointed to by SD. Corporate Social Networks a Waste of Money, Study Finds. Guess I better read it…

leighblackall


It was a morning of sustainability information and design in Second Life this morning.

First up, I attended the opening of the Future Green Chatham Home. I was greeted by the very helpful Jojogirl Bailey who I think manages the Etopia sim that hosts the home. Interestingly the model is 1.5 times a 1:1 scale. It is a well detailed design with all features including information notes to help people interpret the design.

Our active solar (photovoltaic) array provides up to 6KWH and, with the wind turbine, reduces electricity consumption from the power grid, making it virtually a net zero user. Instant-on tankless heaters ensure boundless domestic hot water, and they are a backup to the geothermal domestic hot water system. We recycle grey water to use in the rain garden, lessening soil runoff and preserving water. Clerestory windows and skylights allow for maximum daylighting; and, by using Compact Flourescent fixtures throughout, energy usage is negligible.

While waiting for the official opening of the High Performance Home, another Etopia manager named Willie (I think) gave me a Second Life URL to Choose your energy path at Commonwealth (SLURL). It is quite a project! many examples of homes built around solar energies in one space, and then another space built around nuclear, wind, hydro and waste management. There is another space developed to represent issues of global warming and its apparent impacts on polar ice packs. The solar space is presented as the only viable option for a sustainable future and the designs within that space are interesting.

And finally, the good old Big Green Switch (SLURL) where you can obtain dozens of free things for your own SL modeling, such as a wind turbine, solar panels, compost bins, and whole buildings! Its a wonderful resource and innovative project to get information out there to the users of SL. Oh, and you can offset your SL carbon footprint through BGS.

reading Minsky

The Emotion Machine by Marvin Minsky

Minsky has studied many great writers who have thought deeply about the human mind. Not only contemporary thinkers but he ranges across the centuries (Aristotle, Augustine, Descarte, Darwin, Franklin, Poincare, Freud etc.). Many of the sections of his book begin with quotations and summaries from these writers and then proceed onto Minsky's own independent evaluation of them.

To provide just one example (there are many) in section 7-7 he uses quotations from a book written by Henri Poincare in 1913 as the basis for a discussion and presentation of his own views on a 4 stage model of unconscious processes (preparation, incubation, revelation and evaluation)

In reading Minsky, carefully, I obtain a strong feeling that I am receiving a distillation of some of the best thoughts from the best thinkers in human history from one of the current best thinkers who also happens to be a great writer

As well as that I'm discovering a very plausible view of what the research agenda for our understanding the mind ought to be.

I've been summarising some of it on the learning evolves wiki. In some ways it's a deceptively simple book but quite hard to hold all of it in your mind as an integrated whole.

I read a great post by fellow Nott’s lad Tom Barrett. About getting glue on your laptop. He was of course talking about his desire to see the ‘digital’ backpack in schools. On the one hand, I suspect that most of our kids do have ’secret’ technology in thier backpack. Schools of course like to ‘ban’ anything that isn’t made of paper.

The result is that kids cart about 15 kilos of text books each day. Why? Well ‘just in case’ they need them of course - be prepared for class sunshine!. A hallmark of the ‘just in case’ learning environment.

No teacher would of course, revert to the text book lesson just because they hadn’t got much else prepared before hand. We love our text books, they make teachers feel safe - cause we’ve got the teacher one with the answers and they don’t.

Time-warp time … lets go back 20 odd years …

As a kid I remember looking at the physics text book on a summers afternoon in a hot science lab. The room was silent - apart from the occasional ‘cough’ - or fake ‘cough’ of some other poor kid trying to relieve the boredom too. I had no clue what half of it meant. Day by day, week by week, we moved ever onward.

I knew every poster on the wall, I could tell you the colour of the curtains in every house you could see out the window. I knew every scratched name and comment on every one of the decades old furniture. I knew some of the stuff in the book, well I could recite some facts, but by and large they days turned to weeks and finally it was all over. I left school clutching my ‘O’ Level in Physics - grade ‘C’ - I passed, but really had no clue what it all meant and why I needed to remember it.

I do remember that the school got a ‘research machine’ Z80, and I do remember finding any excuse possible to use it. I’d risk detention, prefect floggings and parent phone calls to get my hands on that thing. I was a programmer - I could get the damn thing to do maths homework for me - another subject that I remember - not for a love of maths - but for the teachers never ending ability to write endless things on a board without ever moving off line, or need to rub out - that woman could measure the real estate of a black board to the inch. We never used the computer for ‘maths’, it was called a ‘research machine’ - no one knew where to put it I think, so it sat in a basement room, next to the staff room - the place where the teachers hid between classes. You knew if you were about to be busted, the smoke plume predicted the approach of the teacher as the door opened.

Tom also posted this photo of the bevvy of new laptops that arrived. Imagine how liberating these are seen by kids. Imagine that they could use them all the time. Imagine if the teacher could do more than get me to ‘google’ with it.

I also thought when I saw this photo that it initially looked like a stack of paper. Then I read ‘Toshiba’. Imagine how much less paper is needed in the classroom by having these. I’ve said before - if teachers quit the ‘photocopier’ habit (some teachers in my school come in during the holidays just to prepare a mountain of that stuff - they call it planning ahead) - then the money would be there to get every kid one of these things.

The point being, that things haven’t really changed in 30 years.

Computers are ’specialist’ tools in school, and the teacher MUST have PD to become a specialist before letting kids near them. Like 20 years of ICT in the classroom hasn’t been enough to master Power Point.

In the mean time we continue to demand that kids carry all manner of pens, rulers, glue and books - but not laptops, PSPs or Phones.

The joke is, when we do ICT - we actually ask kids to leave their backpack outside. How dumb is that! Its almost like bringing paper near a computer will somehow destroy it reverence. All hail paper.

This represents the disconnection that Tom is talking about to me. Go tell it to the scribes I say.

So what is in the backpack? what is so scary?
Schools seem to love to ‘ban’ anything that is not either made of paper - or a tool to write on paper.
The utopia is obviously using ‘the book’ to find the words to write on the photocopied paper that we came in during the holidays for. That justifies us as ‘hard working, committed teachers’.

Let’s face it, kids have mobiles phones on them - yep it’s true! It’s just year 7 that hand them into the office each morning. Sorry to shock anyone there.

Touchy!

Remember in the 90s - Schools taught ‘Touch Typing’?

We used ICT to learn to use a QWERTY keyboard. Brilliant! We invented word processors to get rid of the typing pool and immediately decided to make our kids learn to type as it was now a computer science skill. It was a skill to Marion the typist on floor 7 in the 50s maybe. Who now allocates time to in ICT to ‘learning to type’? I can’t remember it for a few years now. We assume they can use it - they are digital natives (a term I am not comfortable with).

Next, we complain that kids use txt language and MyFace speak! They don’t use ‘proper’ English!

Well consider this. I suggest that it is NOT the desire to kill off the written, proper English that drives them. Its the fact that they use a phone keyboard, predictive text, and have learned to communicate using the least number of characters possible because that is the technology that they had personal access to. Access that doesnt require the teacher to ‘approve’ its use.

So in the 21C classroom, how bad is a mobile phone? Kids can negotiate txt in that faster than they can a QWERTY keyboard.

Next I’d like to take a cheap shot at the good old Scientific calculator! - how may key shift, funtion, tap f1 tap f7 does that take to actually access the function they want? That is a far more complex activity than using a mobile phone, PSP or DS. It also has limited use outside of science and maths. But these things are okay - as they don’t connect kids to their ecosystem.

I don’t see phones as dangerous. The reality is that kids have them, they bring them, they use them, they loose them. With our without school permission - mobile phones, DS and PSP are ubiquitous in high school backpacks.

But these are banned items - they cause problems in the classroom! They can do anything on them!

So true, they can do ANYTHING. As opposed to having their nose in a text book, memorising every knot in the wooden desk. I don’t believe that teachers are so un-creative as to deny that they can take advantage of what is already in their kids’ backpacks. Just like the proxy war, give it up! embrace what is possible! dont waste their time and yours trying to be the last guardian of a mentality thats hardly moved in 30 years.

Kids will live without you photocopying yet more text to go with the text that fades in and out of focus, day after day.

The mobile phone is a networked computing device. The PSP is a networked, bullet proof ‘google’ gadget, they have more power than a calculator, and take less effort for kids to use than a QWERTY keyboard.

Finally, I go back to the ‘writing’ of txt. Kids know what ‘formal’ writing is - they do, really, I kid you not. They also know there is a time and a place for that. (and if they don’t, spend 10 minutes to explain it). Just like they might ’swear’ when in their peer groups, but not in class - they already select the most appropriate language for the context.

As long as the tool is used for learning - whats the big deal if they do a bit of txting in comments on a blog. So what if they want to look up wikipedia on a wifi link to their PSP or N95. Why can’t they record their recount on their iPod or MP3 player? - Maybe they could show you how they could blue tooth it to your phone. Saves carrying around those floppy discs.

Don’t believe me? Ask your kids what they can do with a phone these days. Connect with what is in their backpacks. You might finds a whole new world of learning in there.

Thanks Tom for the original post.

Sarah Stewart, a prolific blogging colleague at Otago, takes on the health sector educators and their almost neurotic hesitance to take on an open web presence and open education. Getting our knickers in a twist?

I am still thinking about the whole issue of confidentiality and blogging, especially in the context of health practice. And I am wondering if some people are getting their knickers in too much of a twist?…

…To be honest, I do not know if there has been an analysis of the content of blogs belonging to health professionals. So I do not know how much the concerns about blogging and confidentially are based in fact or general impressions.

Sarah and her colleagues have devised a simple test to assess the content of email by Health practitioners.

Liam and I developed an assessment tool by which we were able to anilyse the risk to security and confidentiality ranging from 1 — breach of patient confidentiality — indicating a high need for security and privacy of the email’s content, to a score of 8 which had no need for either security or privacy.

The results? Well, I don’t want to steel Sarah’s lime light here. I really think Sarah and her colleagues are on to something and I hope they take it further and chip away at the common (mis)conception that is quite frankly holding Otago Polytechnic health educators back in my opinion. The almost reflex reaction up until now has been a persistant blockage for health teachers even considering open education, but I’m sure there will be a debate even before the research…

Learning is a Conversation!

Yesterday Chris Betcher, he of http://betch.edublogs.org/, was a keynote speaker at the CEGSA conference. The conference theme is Learning is a Conversation, and Chris made some really interesting points that you might like to think about.

  • Learning in the 21st century is social.
    Learning happens through our conversations.
    The boundaries to where we have our conversations have come down. Our potential to connect has changed.
  • Conversations are often informal exchanges of knowledge
    We have serendipitous conversations that are spontaneous
    We didn’t know we didn’t know something until it comes up in the conversation, and then we realise there is a gap in our knowledge
  • We have these conversations in our Personal Learning Communities, Personal Learning Networks, Communities of Practice, Special Interest Groups.
  • There’s wisdom in crowds so long as you have
    - diversity
    - independence
    - decentralisation (dispersal)
    - aggregation
  • There is a danger of the “echo chamber” effect where everyone agrees with everyone else.
    Little learning takes place there
    The best learning takes place when there is an element of disagreement, argument or conflict

Chris argues for using a range of tools
“When your only tool is a hammer, then everything looks like a nail”

This led nicely into my session about blogging, and my concept that a blog can be the initial point in a conversation. Or if you take up an idea that someone else has expanded on in their blog, part of an ongoing conversation.

But of course that is only so if people take the time to respond. What do you think?

ACTA threatens free software

ACTA, the Anti-Counterfeiting Trade Agreement, is a proposed enforcement treaty between United States, the European Community, Switzerland, Japan, Australia, the Republic of Korea, Mexico and New Zealand, with Canada set to join in the near future.

Although the proposed treaty’s title suggests that the agreement deals only with counterfeit physical goods (such as medicines), what little information has been made available publicly by negotiating governments about the content of the treaty makes it clear that it will have a far broader scope, and in particular, will deal with new tools targeting “Internet distribution and information technology”. www.fsf.org/campaigns/acta

This agreement makes it more difficult to distribute free software. Without file sharing and P2P technologies like BitTorrent, distributing large amounts of free software becomes much harder, and more expensive. BitTorrent is a grassroots protocol that allows everyone to contribute to legally distributing free software.

It will make it harder for users of free operating systems to play media. Consumers will no longer be able to buy media without DRM — and DRMed media cannot be played with free software.

To date, disturbingly little information has been released about the actual content of the agreement. However, despite that, it is clearly on a fast track; treaty proponents want it completed by the end of 2008.

Many civil rights groups like the Electronic Frontier Foundation oppose ACTA, calling for more public spotlight on the proposed treaty. A British study found that iPods owned by persons 14-24 today contain an average of more than 840 tracks downloaded on file-sharing networks, nearly fifty percent of all music possessed by this segment. The same study also found that 95% of individuals falling under this category have copied music in some way. Some critics argue that the ACTA directly incriminates the ordinary consumer activity.

I found an excellent article on the Knowledge Ecology Studies website written by Aaron Shaw. Its all about ACTA and what we can do about it.

ACTA would create unduly harsh legal standards that do not reflect contemporary principles of democratic government, free market exchange, or civil liberties. Even though the precise terms of ACTA remain undecided, the negotiants’ preliminary documents reveal many troubling aspects of the proposed agreement. For example, ACTA advocates intend to further criminalize non-commercial copyright and trademark infringements. They also aim to reinforce so-called “Digital Rights Management” (DRM) technologies that currently prevent the personal, legal reproduction of optical discs like DVDs and trample on “fair use” rights. In addition, rights owner lobby groups want the agreement to undermine legal safeguards that protect Internet Service Providers (ISPs) from liability for the actions of their subscribers. It would also facilitate privacy violations by trademark and copyright holders against private citizens suspected of infringement activities without any sort of legal due process.

All of these provisions threaten to reach far beyond existing U.S. and E.U. legal norms without any mandate from the appropriate, elected legislative bodies that govern them. As such, the trade officials involved in ACTA negotiations demonstrate a surprising disregard for their own countries’ democratic political processes and public welfare. They also threaten to overturn the existing balance of rights and regulations established through global governance institutions.

A new book, war and decision by Douglas J. Feith Under Secretary of Defense for Policy from July 2001 until August 2005 seems to provide an authoritative account of what really happened inside the Bush administration whilst planning the Iraq war.

CEGSA - Learning Is A Conversation

Our annual CEGSA conference is underway and being hosted at the fabulous ASMS (Australian School of Mathematics and Science) here in Adelaide. For a small scale conference, the line up of keynoters and sessions is pretty good. Here’s what unfolded today.

Opening Keynote - Martin Westwell, Director, Flinders Centre for Science Education in the 21st Century,
Flinders University. “The Future Of The Mind: how technology changes the way we think.”

My key takeaway from his presentation - video games do hone specific skills in students but should education be including these in the classroom or is our role to focus on other skills that are also valuable but less likely to be part of the students’ lives.

I went to a very good workshop run by Pam Thompson on classroom blogging. Check out her class blog here and give her a shout out on Twitter.

Chris Betcher delivered a great keynote after lunch based on the conference theme of “Learning Is A Conversation” and gave a great big picture view of the PLN concept and the key tools that can be utilised.

Key notes - “It’s not what you know, its who you know!”

So, if learning is a conversation then the more people you converse with then the more supercharged the learning. Showed an opening example from Sheryl’s blog where three educators in Texas hooked up to another in Winnipeg, Canada as part of the K12 Online Conference organising committee.

How to explain and sell what an online PLN is until you dive in and experience it. If you get a large enough group of people, then it is possible to create wisdom from crowds. You need diversity in your network, but you need independence. You also need decentralization _ related the story of how Linux got started as an idea of one person, assisted by decentralized individuals contributing. Final factor is aggregation - but have to beware of the echo chamber. Not much learning if everyone agrees about the same ideas. Best learning happens when there is conflict.

My key takeaway from his presentation - It is hard to explain and sell what an online PLN to educators until they dive in and experience it.

I had two presentations in the afternoon - one with Peter Simmonds where I did a basic re-run of my parent info night on Student Blogging and another which ended up being a ramble about starting up one’s own PLN. It sort of flowed on from Chris’s keynote and used the contributions of the educators who added comments to my Kickstarting A PLN post of a few days ago. Thanks, guys! Hopefully, you all get a few more subscribers out of it and a few more voices to add to your network.

Day two tomorrow, and thankfully there will be no candid birthday pics.
