There are six principles of sticky ideas according to Dan and Chip Heath, authors of Made to Stick. Sticky ideas are ones that we can plainly understand, clearly remember, and easily retell. When teachers and students make educational podcasts, whether audio or video, we want them to be sticky.
I created the infographic below that that applies the principles outlined in Made To Stick to podcasting for teaching and learning. You can click the image for a PDF version of the infographic.
