#ocTEL2014 - Week 3 - Materials & Platforms for Learning Technology

This week's TEL One activity is to
Take the perspective of a learner and spend some time using:
  • one resource from Khan Academy’s YouTube videos
  • one resource from ElearningExamples e-learning games
  • the iEthiCS simulation.
  • What elements of these do you think are appealing to different learners?
  • What learners, if any, would they be inappropriate for and why?
  • How do each of these resources differ from that of the resources we’re using in ocTEL? Do they promote social learning, re-use of their materials, or open access?
  • What ways can you see to improve the effectiveness or potential reach of these resources? 
I looked at "Origins of algebra" and "Introduction to variables" videos on Khan Academy.

To me, they seem to present material using a coherent story with attractive visual aids. However, beware that this can be a very biased view given the sample I have used is not at all representative of the thousands of videos also I am familiar with both topics.

I think this type of videos will be appealing to younger generation (say below 25) and would be good for introductory materials. From my experience in our FutureLearn course "Begin Programming:build your first mobile game", which attracted over 48 thousand entrants over two runs, many elderly participants preferred reading materials to videos. However, I am unable to back this up with evidence from post-course surveys as we have not got the demographic details captured in them. Nevertheless, during course discussions over and over again we saw that elderly participants (mostly leisure learners) many of whom were the Open University alumni preferred reading materials to videos. 

* One good thing about these videos are they give you a "quick view" to the topic, serving a similar purpose like Wikipedia. However, does this encourage deep learning I don't know.

* These are stand alone resources - OERs. So there is no way to interact and ask questions. Well in a way you can use the comments. 

* But as the Khan academy founder said in his TED talk, you can pause, replay and listen multiple time which is good for learners who may be struggling to grasp the subject matter or the language. 

These pros/cons have been already discussed in the ocTEL forum by Teresa MacKinnon @warwicklanguage 's articulative post.

With my developing country research experience, one major problem with this type of resources is that they require large data volume downloads. During my PhD research I got to know that in Sri Lanka, the internet access centres set up by the government's Distance Education Modernization Project had blocked access to YouTube website because of bandwidth issues (You can read more about my findings in my blog "Using non-Personal Computers for eLearning" or the research paper "Using non-Personal Computers for eLearning: Sri Lankan Experience" published in the Journal of Education and Training Studies). 
The resource being offered in video format reduces its reach to many learners who do not have good internet connectivity. I suppose one way to increase the reach for this resource could be to provide it in various formats: transcripts with illustrations;audio download and video.

PhD Experience: I wish I knew....

Recently I participated in a session for Post Doctoral Researchers on supervising PhD students. Along with me there were about 20 attending the workshop. One of the first activities we had was to list down the best and worst three experiences of our PhD journey (relating to supervision). I've said this before and I am saying this again, I had the best supervisory panel that a student could ask for. I started with two supervisors: Prof. Andrew Adams as my first supervisor and Prof. Naz Rassool as my second supervisor and ended with three: Prof. Shirley Williams as my first supervisor with Andrew and Naz as my second supervisors due to change of circumstances. All three supervisors are unique in their own ways and experts in their area. As I was working across disciplines it was so enlightening to have had such a brilliant combination of supervisors. They were so supportive through out and even after completing my PhD I am still collaborating with them on various publications. Given my extremely positive experience throughout, I found it very difficult to come up with 3 worst experiences.

However, not everyone in the workshop has had such positive experiences;I felt sorry for some of the people who have had tough time. I did have difficulties during my PhD not due to supervision I received but due to my own personal circumstances, for example caring for baby twins.

Participants listed things that they thought would be helpful had they known it earlier. From my notes I am noting them here hoping that someone will benefit from them.

Year 1
Start writing early
Use your time off
There is nothing called criticism it is all feedback
It is not Nobel prize - it is an apprenticeship
Having right resources

Year 2
Time spent planning is never wasted
You don't have to do it - if you don't want to
It is OK to disagree with supervisor

Year 3
You never actually finish it - learn to write up - it is good enough
Think hard about disagreeing with supervisor (you may have missed the point)
PhD isn't the end
First chapter will be full of red ink
