So what’s the problem with lecture recordings?

Monday, April 18th, 2011

There has been some recent commentary about the value of recording lectures at university and elsewhere (see Mark Smithers’ blog and comments). To set up and automate such a system involve high infrastructure costs, and questions being asked about the return on investment with regard to use & reuse of recordings. Just how

At my university there is a significant usage of recorded lectures, and students demand access to them. Staff are stressed over whether the recordings have worked and are of good quality. Some staff even fear that they will receive bad student evaluations if the system fails and students complain over not having access to recorded lectures to supposedly review their study.

I don’t want to go into the pros and cons of recorded lectures or of the systems that support them. What I wanted to write about was the process we’ve just begun of reviewing our current lecture recording system. We undertook a logic mapping workshop with relevant stakeholders from across the university and spent some time working through strengths, problems, solutions and benefits (sort of like SWOT but different).

One of the outcomes of this process was to suggest that we may need to think differently about our idea of what a lecture is. The technology has been constraining the paradigm of what we understand the lecture to be. Originally developed to be able to record the delivery of an oration and maybe also capture a series of powerpoint slide or some video, the software was modelled on the idea of one teacher talking to an audience (of students). Blended and flexible learning paradigms are showing us that the traditional oration (while appropriate in some circumstances) needs to be adjusted to support new ways of teaching and learning.

I’ve been encouraged that we will be developing a proposal and framework that understands that we may need to record more than just a stand & deliver lecture. We’ll be seeking to be able to record interactive lectures, short ad-hoc talks & presentations (with or without video). The aim then, is to also be a catalyst to help teachers come to understand different models for getting a message across.

As Stephen Downes recently argued in a debate, ‘The Lecture Must Stand’, it just needs to be adapted appropriate to the need.

 

a new(s) ways of looking at disasters

Thursday, January 20th, 2011

Current technologies are enabling us to participate nearly first hand in disasters as they occur. As the incredible footage of a small creek rising very quickly and carrying off away parked cars during the flash flooding in Toowoomba on Monday 10 January 2011 demonstrates.

 

I remember seeing a tweet about this clip and watched it when the count was only around 350 on the the 11th of January. now there have been over four and half million views 10 days later. There is a demand to see these things from a real-life perspective, and with digital still & video cameras and access to fast internet and the of networking power of social media we can just about be there.

Here’s a link to a PhotoMap (satellite image) by NearMaps that shows the flooded suburbs of Brisbane as at 13th January. Where you can see the date (at the top of the picture is a time line so you can scroll back (or use the drop down menu) through time and see the changes in water levels. You can zoom in and out of the image and scroll just like on Google Earth. Try clicking on the ‘Multiview’ and check out the ‘More…’ buttons too.

The ABC News Online team developed these remarkable before and after infographics of the Brisbane floods. Brisbane floods: before and after & Brisbane Floods: Up Close.

I find it amazing that we have such ready access to this resource of rich information. The mind boggles as to what educational purposes this might be put. I can imagine students making the most of material like this to illustrate and explain the phenomenon of disasters, and all the while having a (nearly first hand) context that might provide a deeper level of understanding.

mobile devices in education – is the iPad proving itself useful?

Saturday, September 4th, 2010

I’ve been thinking lately about the impact of mobile devices in education and wondering what some of my colleagues are thinking about using an iPad. There’s been a moratorium at my workplace on purchasing the iPad with university funds. We haven’t really heard the reason for this, but understand some work is being done on how they can be implemented. I just want one to test, evaluate, and use at work with the aim of determining their usefulness for supporting professional development and learning and teaching. While initially acknowledged as a brilliant tool for consuming content, I’m coming to understand that the third party apps available for the iPad will make it just as useful for content creation and collaboration.

So, I’m waiting for one – but there’s quite a few of the devices appearing and they been purchased by individuals who are using them at work. I did chat to one person who was struggling trying to keep the device going during a meeting. It seemed the bluetooth keyboard was using more power then the recharger could supply (I’ll have to ask some more questions about that). Someone else was going paperless and saving all their attachments (meeting agendas, minutes, reports etc.) to iBook as pdfs and reading them off the bookshelf. There might be other ways to do this and maybe converting to epub would be better for reading. Need to do some experimenting for myself I think.

Academics are finding that students are bringing their iPads to class and using them as an instant research resource. There may an issue of distraction etc. but could be useful if managed correctly for specific class work for either individuals or groups. They can also be used with a document camera (& the optional vga connector for TVs/projectors) to share what’s on the screen. Nice way to show capabilities and demonstrate apps such as interactive books, google earth, and discipline specific applications such as maths & science.

I recently read an article by Louisa Burnham, iPad Travelling Cold Turkey, where she reflected on using an iPad exclusively while travelling for 6 weeks in Europe and doing academic work. This gave me a good insight to what to expect and what’s possible with regard to working without a fully featured laptop. I’ll also be interested in the result of Dean Groom’s project underway at Macquarie where they are asking staff to evaluate their use of an iPad for a couple of months.

The iPad might just a step or two away from a device that will be the ultimate tool for learning (amongst other things). I haven’t been able to do a lot of testing myself yet, and look forward to being able to put one of these through it’s paces. I’m finding it hard to imagine that something might replace my MBP, but recognise that it’s going to happen sooner rather then later.

PS. and then there’s the new iPod Touch. Upgraded to include the new Apple iOS4, now features a camera and ability to capture HD video, do video chat/call via wireless using FaceTime, and has the 3 axis gyro built in. Cool!

we are changing our LMS – exciting and daunting at the same time…

Thursday, August 5th, 2010

Another busy week so far and the highlight was that we were able to announce (internally) that our university has chosen Desire@Learn as it’s new Learning Management System. While we haven’t announced anything publicly, D2L made this announcement last week. It’s all very exciting as we’ve been using the same system for the last six years (Blackboard Vista) and it has come to the end of its life and we needed to find another platform to support our learning and teaching program. Our short list of potential systems were BlackBoard Learn (v.9), Desire2learn, and Moodle. Personally I thought that the open source route with Moodle and the Mahara ePortfolio would have adequately suited our needs, but the decision’s been made, and D2L it is. Lots of implementation planning underway with configuration, integration, training, migration, trails & pilots all leading toward a phased rollout from Trimester 1, 2011. So, the job is ahead of us and I’m keen to see us make use of some of the available functionality of D2L like their competencies, analytics and learning design tools, as well as the ePortfolio. I’m expecting lots of challenges as well as an excellent adventure over the coming 18 months…

On another matter, I tweeted this during the week,

“@colwar interesting the difference a simple explanatory conversation can make to clear up misconceptions. (let’s have more of them)”.

It was in response to a situation were I was able to explain how a certain new technology worked and give some people have a better understanding of how the technology functioned. I suppose I’m wondering why people don’t seek out good advice and want to know more about something, rather than rely on someone else to make a decision without explaining letting stakeholders know why. Maybe we all just need to make space (and/or go out of our way) to have more conversations and share the knowledge we have. I believe the spent spent doing that would easily cover the delays encountered vacillating around in the unknown.

augmented reality software/applications and educative possibility

Monday, September 21st, 2009

I’m just staring to understand the applications/technologies underpinning what’s being called augmented reality. Lots of fun, amazing to see and a high potential for use in education. I had seen some of this stuff before but didn’t quite get it even though it’s been around for a while. I’m not drawing parallels or comparisons to (immersive) 3d virtual worlds as I think that they are a different application of (augmented) reality (or do you think they should be considered in the same genre of application?) I’m interested in the application of this in education and how it might support authentic learning experiences that help build students’ understanding.

Here’s a video of a demo of a free (cross platform) application from ARSights to take you on a tour (via a collection of models linked in Google Earth) of some of the significant landmarks around the world on your desktop. All you need is the marker (use the same cutout for all models) and a camera connected or built into your computer. You can also download the models from via Google Earth and view them at your leisure

Having someone demonstrate an application to me (drum sequencer) I’m starting to understand that there could be significant educative value of this technology. Basically it’s a visual marker recognition system that uses a camera to ‘read’ a marker (a bit like a QR code) that then overlays a 3D image of the object on the card that is viewed on the computer screen. These can moved/shifted around to change the output of the sequence, a little like the concept of siftables demonstrated during a TED Talk by David MerrillThe interactivity is important to note, as it adds a another dimension to this technology as suggested by this quote from d-touch website:

“The distinctive feature of d-touch, compared to similar systems, is that the markers can be visually designed to convey meaning to people. By allowing the creation of markers that support interaction both visually and functionally, d-touch can enhance most applications normally supported by visual markers, including interactive guides, mobile service access, mobile games, interactive story telling systems and augmented reality applications that have broad visual appeal and are not constrained to ugly glyphs.”

The video below shows a demo from d-touch and a drum machine ‘reading’ the markers to play a sequence.

These technologies is also being developed for mobile devices with some clever and useful applications. The demo below is nearly too cool to believe!

There must be any number of possibilities for education, eg. 3D models for architecture, medicine, chemistry, biology, etc. Are you aware of any other demonstrations/applications of this type of technology in education that you could share? … and what of uses for mobile devices?
