Explain a concept, and then present a few multiple choice questions requiring a thorough understanding of it. The distractors should be convincing. Have students choose an answer for each by themselves, and then pair up with another student to compare answers. Tell them that if they do not agree on the answers that they should explain the concept to each other until they agree on the correct answers. Go over the correct answers as a class and have groups tell you when they disagreed and what it took to get to an agreement on the answer.
Remember that this is just an example of how to get started
with this Teaching Method.
