This document discusses using Moodle quizzes to improve learning in large first year physics laboratory classes at UNSW. Previously, students would copy each other's preparatory work in the lab manual. Now, students must complete a pre-lab Moodle quiz before each lab, covering the required reading and videos. This ensures students come prepared and allows demonstrators to focus on helping students in lab rather than checking preparatory work. The quizzes have reduced plagiarism and helped labs run more smoothly and efficiently with fewer delays. Moodle quizzes provide formative assessment and feedback to further improve student learning and preparation for labs.
