Encourage discussion and engage with students during classes by asking questions that require responses.Include regular opportunities for students to discuss key points among themselves (attention tends to wane after 15 to 20 minutes). Suggested activities include: think, pair, share buzz groups (small groups of students responding to a question) debates role plays problem-solving task demonstrations the one minute paper (students spend one minute writing the main point of the class) mini quizzes or true/false responses a show of hands to a particular question.
