In order to meet students’ diverse learning needs, it is beneficial for course developers and instructors to consider UDL guidelines when designing online learning experiences, whether it is as support of face-to-face courses or fully web-based ones. Previous studies have shown that mind maps have the potential to include multiple means of representation and expression by providing ways to improve remembering, understanding, and knowledge organization through different modes that combine text, images, colour, and layout. This chapter presents a descriptive case study of the Mathematics Education program at Western University, wherein online mind mapping has been included as a strategy for collaborative work for over three years. For this purpose, three different tools—Popplet, Mindmeister, and Mindomo—were used in the courses. This chapter describes the development of the mind mapping activities, along with general reflections in terms of engagement, representation, and expression.
