In 2022, Martijn Boussé received a grant from the Learning & Innovation taskforce to implement weekly online quizzes for multivariable calculus in collaboration with students. The project brought together staff from the Faculty of Science and Engineering (FSE) and the School of Business and Economics (SBE). Crucially, the quiz system used randomization, parametrization, diversification, and answer-dependent feedback to make the learning experience more meaningful to students.
