As I'm teaching subjects this year that, I've not taught for a while, and as these same subject/s have moved technologically, I've begun writing lessons and course materials using Apple's excellent presentation tool; Keynote.
As I'm doing them mostly from scratch, it is taking a long time for one 20 minute presentation. The workload is spread between source resources and writing the content. i think that I should write the content first in a word processor then put it all together at the end with the final stage being adding the fancy effects.
On another note, this website wakoopa.com has a handy way of tracking what software you use, giving some insight into what and how long you spend on projects on your computer, not the first I'm sure, but as it's online and has a web 2.0 social flavour definitely interesting.
