I've just signed up after stumbling upon this site. (Doing my research ;).
After Christmas, I'm teaching a 2D Game Engine module for a GCSE-level course to 35 students. This looks like it could be just the thing.
I like to ensure the stuff that I'm doing will be relevant for the future and HTML5 is definitely that. The unit is more about games design than programming, (they have to design a 2D game element), but the important thing at this level is that it gets them thinking about the construction of the game elements, mechanics etc. It gets them used to development. Then after that we can bring in code. It's also great that it can run on a plethora of platforms in the browser without any fiddly recompiling etc - a great way to sell it to the learners: "Look! What you've done can run on this system, and this system, and this system".
We are running XP on the desktop at college and so the default IE won't run HTML5. I've put a request in to have a better browser installed in the computer room we use but worst case scenario is to use the Opera USB version which seems to work great.
It's also a big bonus for the programme to run off USB. We can get software installed on the network, but the technicians can only do it every so often. If a new release comes out it's great to be able to run it immediately off USB.
I'll be playing around with this software a lot over the Christmas break :)
Tom, can you PM me with details of Edu licences? Thanks
