Multiple choice questions are a common method of assessing student understanding. In this article, the authors discuss and evaluate a student-focused collaborative learning strategy for working with such questions that results in greater student learning and allows instructors to better understand student thinking and ultimately to write better multiple choice questions. In this strategy, the authors distributed one question with four possible answers to each student. Students read and answered the question individually and wrote a better answer option if they thought it appropriate. Students then divided into groups of three and examined the question and answer options together. For each option, they decided if the option was correct or incorrect and provided the reasoning that supported their determination. After they examined each option, each team created "the best possible answer" to the question. Each team wrote its best answer on the board. Finally, the instructor summed up the activity by reviewing the original question and highlighting the strongest elements of each team's written answer. (Contains 2 figures.)
