There is Beauty in Simplicity
Shorter self-paced videos allow less time for distractions to happen and actual learning to take place. I think of "less is more" in terms of this. Give your learner less, but by doing that you are also giving them more because they will want to continue filling in the blanks and research more about the topic.
Walk and talk! How did I not think of this! I feel as though I do some form of that within my classroom with Jack Hartmann videos (if you know you know), but it's usually with math. I would really like to do something like this with my reading block.
