Screencasting
Screencasting is a great way for teachers to create a "how to" video, a flipped video for content acquisition, or personalized materials for their classes. Students can also use screencasting for their own presentation needs. Here are some suggestions:
Screencast-o-matic is a program that works best when downloaded and installed, although it can work inside your browser.
If you are using Chromebooks, Screencastify is a popular choice. It is an extension in your Chrome browser, and videos are automatically saved to your Drive. (Note: the free version is limited to video lengths of five minutes.)

Last but not least, Macbooks have a built-in screencasting option. Click here to view a how-to video.
