Initially, I was upset. Should I redo my plans and do something different tomorrow? It was then that I remembered that I would be missing about 10 students in total due to a field trip. For those students, the screencast would allow them to stay caught up. Maybe it wasn't so bad that I did the screencast after all.
screencast-o-matic for doing screencasting. Screencast-o-matic is free for the 15 minute version. If you want to make screencasts longer than 15 minutes and you want to be able to use the cool editing features (like splicing and annotating), it is worth it to pay the extra $30 per year fee.
