Screencastify is a Chrome extension that allows you to record your screen while also recording your voice.
There are a lot of different ways this could be used in the classroom. I actually learned about this specific extension from a student who was using it to create a project for Mrs. Ewing’s class. They used this tool to record their computer screen instead of recording themselves on video teaching their content.
Another use for this extension could be to record notes or lessons to share with the students. A teacher could record themselves talking through a PowerPoint to provide students a lesson when the student is absent or when the teacher has a substitute.
There are lots of options with tool, and I would love to help you explore it more if you are interested.
