I won't write much because I'd rather you just watch the video.
Here is one reason why I flip the classroom. This happens all the time.
Nicholas missed out on key parts of the lesson. He found himself at home not knowing how to proceed with the homework. He remembers I mentioned the videos. He finds them. He watches them. He watches more. They help him. He takes his own notes...totally independently.
He didn't find the videos useful.
He found them very useful.
This stuff is easy to do. The problem is, once you start you won't stop. If you are interested in starting to make screencasts and flip your own classroom you can click here.
