This document summarizes strategies for dealing with common challenges that may arise during teaching sessions:
1) For students who arrive late, it is best to focus on those who were on time. Whether to allow late students to join depends on how late they are and the audience. Registration should clarify start times.
2) To engage undergraduates, use humor, give problems to solve, involve students through questions, and personalize material with passions.
3) For international students struggling with language, clarify terms, provide written materials, use visual tasks, and form mixed groups for support.
4) When someone interrupts to tell you things, let them speak briefly, continue discussion later, or get group feedback
