For those of you who teach and/or give presentations, you might be interested in a new video that I put together regarding cognitive load. It addresses at least two main questions:
- What is cognitive load?
and - Why should I care about it?

- Don’t place a large amount of text on a slide and then talk about it at the same time — doing so requires much more processing than most people can deal with.
- Consider creating two versions of your PowerPoint files:
