Looking further at Vygotsky’s ideas

November 11th, 2009 by Jo Turner-Attwell

I wrote about Vygotsky and the Zone of Proximal Development quite a long time ago now, but recently I’ve re-read some of the feedback I received, particularly that from Stephen Downs.

In particular I think its important to look at the role of the ‘teacher’ within Vygotsky’s theory as it was one of the major flaws that a ‘teacher’ was necessary for the process to take place and it seemed to disregard ‘individual’ learning which is also an important process.

Now where my argument with this arises is what is meant by a teacher? Does a teacher necessarily need to be a physical person or can a book or internet sources be also counted as a form of ‘teacher’, particularly with the rise of things like internet courses. I mean when you look at things technically, when one is learning ‘individually’ from books or internet, yes the person is carrying out the learning themselves but they still have assistance from another person in the person who has recorded or discovered these things. In essence they are still learning from others and then further it into their own ideas and opinions from there, as in Vygotsky’s theory of Zone of Proximal Development. In that sense the Zone of Proximal Development changes in that it does not need to be led by one teacher but in fact students have the ability to channel their own ZPD in the direction they so choose by drawing upon resources. This is particularly important now that social networking and internet are so easy to use, students are able to reach the top of their ZPD using such resources.

An example of this is maybe the way computers or new technology progresses, the first computer looked incredibly different to laptops today and change is made through studying current systems and building on ideas and then introducing new ones. The further thoughts and ideas progress the further the room for us to learn and reflect to build upon that learning.

Making ‘Do Institutions have a Future?’

November 6th, 2009 by Jo Turner-Attwell

We created ‘Do Institions have a Future?’ for the Jisc Online Conference 2009 ‘Thriving Not Surviving’. Filming, acting and editing was done by Graham Attwell and myself, with help from Helge Staedler our on-the-spot cameraman. Making this video and getting it to work efficiently took around 3 days with pretty much constant work as we stretched iMovie to its very limits using green screen, video within a video and keynote graphics. You can access the video through the link below and then I have written a bit about how we made it for those who are interested.

We filmed our green screen using a chromakey green screen on a curtain rail and two garage lights and masking tape to pull it vaguely taut, trying to keep costs as low as possible. As it is possible to see, our green screen isn’t perfect due to shadow and some creases in the screen. We struggled with the shadow problem as we only had 2 lights which we placed either side and really we needed an extra one in the centre. The creases problem could have been solved with an iron as we found that in general our problems were not related with the screen not being pulled fully taut but rather creases in the screen itself. Another point I would recommend when using green screen is having a shot without the people in at the end of your movie. We were unable to do this successfully; however, at the end iMovie does allow you to improve your green screen as long as this shot is contained within the video.

To edit the video we used the advanced iMovie tools which can be turned on in iMovie preferences. When editing, green screen and video within a video are very easy to use as all that needs to be done is for the main video to be dragged over the desired background and iMovie will present you with a menu including green screen and video within a video. To create Graham’s intro which involves both actions which iMovie doesn’t allow, we first played with the green screen and gave Grahams head a proper background and then exported the project and reimported it as part of an event making it one video in itself. This meant we could then use this to drag over the slides to use video within a video to have both effects running simultaneously.

The news intro and many of the backgrounds within the news clips were made using Keynote slideshows, which can be exported as a photos or a video. This meant I could change the size or position of  photos within plain slides so they would be more easily seen, or create video clips, such as the economic downturn clip, animated using the inspector. I also found it was effective for making logos as this was where I made the Research Rights Management logo in a matter of minutes. When exporting Keynote files as a video its important to remember is to ensure that they are set to fixed timing as Keynote always resets to manual timing which then can’t be imported into iMovie, a mistake I made at the beginning.

iMovie was not happy through much of the editing and we had huge issues with one of projects which we still don’t know the reasons for. It refused to open properly and eventually we had to export in its intermediate stage reimport it and edit it from that point. Also because of these problems much of the video was made in separate projects and over two computers as both seemed to have problems with our data. It was only put into one video at the end by exporting and importing, though as long as green screen is not split which ours was, it is also possible to copy the whole projects and paste them into one another. However, we managed to find work arounds to the majority of our problems and the import export process was a method which we found to our surprise worked well despite thoughts that it may effect quality.

The video still has much room for improvement and I could have easily spent much longer editing and playing with the timing, probably some of the problems being only apparent to me, but any comments at all on how we could have improved the video and our use of green screen would be most appreciated.

    News Bites

    News from 1994

    This is from a Tweet. In 1994 Stephen Heppell wrote in something called SCET” “Teachers are fundamental to this. They are professionals of considerable calibre. They are skilled at observing their students’ capability and progressing it. They are creative and imaginative but the curriculum must give them space and opportunity to explore the new potential for learning that technology offers.” Nothing changes!


    Graduate Jobs

    As reported by WONKHE, a survey of 1,200 final year students conducted by Prospects in the UK found that 29 per cent have lost their jobs, and 26 per cent have lost internships, while 28 per cent have had their graduate job offer deferred or rescinded. 47 per cent of finalists are considering postgraduate study, and 29 per cent are considering making a career change. Not surprisingly, the majority feel negative about their future careers, with 83 per cent reporting a loss of motivation and 82 per cent saying they feel disconnected from employers


    Post-Covid ed-tech strategy

    The UK Ufi VocTech Trust are supporting the Association of Colleges to ensure colleges are supported to collectively overcome challenges to delivering online provision at scale. Over the course of the next few months, AoC will carry out research into colleges’ current capacity to enable high quality distance learning. Findings from the research will be used to create a post-Covid ed-tech strategy for the college sector.

    With colleges closed for most face-to-face delivery and almost 100% of provision now being delivered online, the Ufi says, learners will require online content and services that are sustainable, collective and accessible. To ensure no one is disadvantaged or left behind due to the crisis, this important work will contribute to supporting businesses to transform and upskilling and reskilling those out of work or furloughed.


    Erasmus+

    The European Commission has published an annual report of the Erasmus+ programme in 2018. During that time the programme funded more than 23,500 projects and supported the mobility of over 850,00 students, of which 28,247 were involved in UK higher education projects, though only one third of these were UK students studying abroad while the remainder were EU students studying in the UK. The UK also sent 3,439 HE staff to teach or train abroad and received 4,970 staff from elsewhere in the EU.
