Episode #3: Cognitive Load Theory in Computing

Home > Articles > This Article

This month we’ve decided to focus a whole episode on a single aspect of pedagogy and how it applies to teaching computing. Back in September the National Centre for Computing shared its first Pedagogy Quick Read focused on Cognitive Load Theory. I sat down with Duncan Maidens from the Raspberry Pi Foundation to talk about the importance of considering cognitive load when designing teaching activities.

Thanks to Duncan Maidens for his contributions to this episode, and a special thanks to Oliver Quinlan for our intro theme built from Commodore 64 sounds.

You can (and should) contribute your thoughts and expertise by emailing the team or by leaving us a voice message, which we may include in a future episode.

We want to make a podcast that is both interesting and useful to computing educators, and to do that we need your help. Complete this feedback form to tell us what you liked (or didn’t like) and what you’d like to see more of.

Thanks for listening!
