Short videos can be great, if they are short. One problem with professionally produced videos is they often provide valuable information but take 25-45 minutes to convey the information. While audible and visual learning are good, static sitting and watching a 30-minute video can lose students while our attempt is to engage them. So, where possible a short 2-5 minute video that demonstrates some point in a discussion is a terrific way to break up the learning into digestible bits using multiple media sources. We want to avoid having the medium be tedium!
