On this, the 43rd episode of Combinations and Permutations Brandon Metz, Cody Palmer, and Samuel Hansen got together to record about an hour of surprisingly sincere and honest audio on mathematical teaching. Unlike most episode there is not a long list of links to wikipedia articles or pop culture minutiae to post here so instead I will leave you with two videos that were mentioned in the episode and the list of terrible teacher types.

First the List:
Mr. Looks-Only-At-the-Board
Mr. Engages-With-Only-a-Single-Person
Mr. Changes-Variables-While-Slamming-Markers-Into-the-Board-and_Erasing-Half-of-the-Work-Because-it-is-Really-Really-Wrong-and-Hands-Out-a-Ream-Worth-of-Wikipedia-Articles-as-Reference
Mr. Egotistical-the-Content-Doesn’t-Really-Matter-I’m-Only-Going-to-Talk-About-Myself

And now the videos:
