Today, I was discussing with an adopter the question of whether the TWEN quizzes should be mandatory. Last semester, I did require that before each class students had to answer on TWEN the quiz questions found in the text assignment for that class. See my Fall 2012 Syllabus. When reading the course evaluations, I learned that some students resented the requirement because the requirement resulted in their spending significantly more time on the Professional Responsibility course than on their other lecture courses. While I believe that answering all the TWEN quizzes before class (and learning the correct answers) helps students learn the material, the primary purpose of the quizzes to provide students with a tool for self-assessment. Accordingly, balancing the anxieties faced by today’s law students and the benefits of the quizzes, I plan in the future to encourage the students to take the TWEN quizzes before each class, but not require them.
