When people talk about the use of video in education, people usually talk either about knowledge clips or about distance education via video conferencing. However, there is much more interesting to report about the use of video.
By increasing your knowledge of the various possibilities of video, both from a technical and a didactic perspective, you as a teacher are much better able to determine when and how you can best use video in your own teaching.
With the use of video you can significantly improve your teaching, especially if you encounter specific problems such as procrastination among students or a very different entrance level. Maybe your educational subject is a stumbling block and you want to do something about it. However, keep in mind that using video doesn't automatically solve these kinds of problems.
