Learning takes effort. Watching a video is a relatively passive activity. It's one thing to listen to a video presented by a person who understands the material. But it's quite another thing to apply the information from the video in an effort to personally understanding the material. This page lists a variety of tools that can used to put the new learning to use. The tools include those that can be used by students and those that can be used by teachers with their students within the classroom. Related resources are also included among these tools.
