For the last ten years I've been working in international schools in Thailand teaching ICT (Information Communication Technology) and Computer Science, prior to this I have worked for several years in software support and also taught English as a Foreign Language. I'm particularly interested in using ICT as a tool for transforming education and in the impact of open source technologies upon learning.

Screencasting is the real-time recording of screen activity. It is used largely as a means to create how to tutorial videos for software. I use screencasting to produce tutorials for students, but it is also nice to have the students themselves create videos themselves. Camstudio is a popular option, however one of its main drawbacks is that the files are created are rather large and need to be compressed afterwards. Jing on the otherhand produces videos that are uploaded to the jing project website. Both these programs are free, however if you are more serious about producing screen tutorials then Camtasia may be your program of choice. Unfortunately, this comes with a price tag.

Thank's to Chris Smith I'm now a convert to Screenr. The main advantage is the high resolution and direct storage on the Web. If only more tutorial videos were produced at better resolutions like those made with Screenr.
