EDpuzzle is great since it is connected to Google Classroom and keeps tracks of data such as responses and view time. This way you can check who has interacted with your video. In the video itself, I wanted to make it interactive, it is a problem solving lesson. The nature of problem solving in class usually has the teacher demonstrating followed by student practice, then teacher demonstrates a different question, which is again followed by student practice. I took on this lesson plan design into the video itself. Hope you enjoy it!
