The final way to use humor in lectures is to use feedback and reflection, which means using humor to elicit and evaluate your students' reactions and learning outcomes. This can help you assess your humor's impact, adjust your humor's style and frequency, and improve your humor's quality and suitability. For example, you can use humor to ask questions, check understanding, or review concepts, such as quizzes, polls, or games that are humorous and interactive. You can also use humor to solicit feedback, encourage participation, or acknowledge achievements, such as compliments, rewards, or incentives that are humorous and positive. However, be careful not to use humor to criticize, embarrass, or discourage your students, as this might harm your relationship or motivation. You also need to reflect on your own humor, to identify your strengths and weaknesses, and learn from your successes and failures.
