We had an interesting presentation from Russell Stannard from Westminster on screen capture software. I was aware of commerical products such as Camtasia, but I had never come across Jing before. Jing is a free and very simple screen capture tool, which enables you to record screen and commentary. (I did this years ago with Lotus screencam, but this is much easier). One of the neat things is that the files are stored remotely and you just have a short URL which you can sent to students or embed in a web page. Russell uses it to give individual feedback to students – by recording himself marking their work. They can watch him underlining things in their own document and hear what he is thinking as he does so!
He has also used the software to create a set of training videos – aimed at EFL teachers, so if you want to find out how it works and also learn about twitter or Jing, just have a look here
