To test my hypothesis, I began to regularly record my lessons and post them on my teacher website for all of my students to access. (educationnext.org)
Why not record your lesson as if you were creating a flipped classroom, but then play it as the first part of your lesson. (edutopia.org)
Also, unless I need to make updates or change something in a recording, I can record my lessons once and then use them every year. (edutopia.org)
