Welcome to our very first installment of “Ask the Cult,” our call-in advice show for teachers and anyone else with questions about teaching, learning, and education. In this episode, we hear from a science teacher who wants advice on making his class more challenging for gifted and advanced students, a graduate student who needs help keeping her online bookmarks organized, and a teacher who doesn’t know what to do about a co-worker who mistreats students right in front of her.
