Interactive lectures are didactic learning sessions in which the instructor uses an activity (sometimes called an “engagement trigger”) to promote learner engagement with the course material, at least once during the lecture, but ideally more than once. Familiar techniques include think-pair-share, one-minute paper, and muddiest point.

Why Would I Use Interactive Lectures?
Interactive lectures are used to capture and maintain learners attention, and the techniques allow learners to apply what they have learned or give them context for upcoming material. In addition to increasing attention, this style of lecturing can result in increased learning and retention of information.
When Can I Use Interactive Lectures?
All lectures should include opportunities for learners to interact with the material as a way to promote critical thinking and information retention. Lectures that are longer than an hour should ideally include multiple strategies.
