As teachers we attend so many meetings and trainings that unfortunately take us out of the classroom. While these can be useful, these missed days can often break the flow of your unit of study, causing you to have to take an extra day to make up for lost time.
Enter: the video lesson.
This isn’t anything novel, for many teachers use videos to teach lessons. If you have some form of a flipped classroom, then you do the content acquisition via video lesson, and the activities in class the next day. It takes the in-class lecture part out of the equation and gives your class more time to get down and struggle with the new concept under your watchful eye.
I don’t always use a video for lesson plans since my screencasting and editing chops were still clunky. However I’ve recently had more practice creating videos about embedding content, so I’m quicker and more comfortable with the process. I decided that since my students will probably miss me dearly, I would make them (and my substitute) feel better by giving instructions for the day via video.
