Over the past three years we have worked on an NSF-funded project to develop LEMBS for use in post-secondary math classes. LEMBs are mathematical modeling/problem-solving experiences driven by student-collected data. Students manipulate and interact with real-world biological mechanisms, construct their own mathematical descriptions and gain a deeper understanding of underlying mathematical relationships.
