If a picture says a thousand words, what does a short video say? Screencastify is an awesome tool for making short videos of your computer screen. It is great for filming for a how-to, or even short lessons. In the free version, videos are limited to 5 minutes or less, but really, that is a LOT of time to explain one concept. Videos can be saved to your Google Drive, or uploaded to Youtube as well!
Screencastify offers 3 courses to help you get the best out of the tool. 2 levels for teachers, and 1 level for students!
If you finish any of the courses, be sure to tweet at @nltatesic and let us know!
