At one point, I decided to try something new to force students to have to interact with the material. Instead of spending many hours making the notes and study guides better, more colorful, more available, I decided to start putting my time into making practice quizzes in Moodle that students could take as they studied.
I set up the quizzes so they could take them as many times as they wanted and encouraged them to do so until they had earned a perfect score. Sometimes, I built in feedback so students would know immediately whether they had answered correctly and why. Sometimes my practice tests contained actual items they would later see on their test, and sometimes not.
My experiment produced extremely favorable results. Test averages jumped. Anxiety levels on the day of the test seemed to plunge. And the two probably had an effect on each other.
