Summary

How active learning improves calculus teaching, and using machine learning to map odors in the smell space First up on this week’s show, Laird Kramer, a professor of physics and faculty in the STEM Transformation Institute at Florida International University (FIU), talks with host Sarah Crespi about students leaving STEM fields because of calculus and his research into improving instruction. We also hear from some Science staffers about their own calculus trauma, from fear of spinning shapes to thinking twice about majoring in physics (featuring Kevin McLean, Paul Voosen, Lizzie Wade, Meagan Cantwell, and FIU student and learning assistant Carolyn Marquez). Next on the show, can a computer predict what something will smell like to a person by looking at its chemical structure? Emily Mayhew, a professor in the department of food science and human nutrition at Michigan State University, talks about how this was accomplished using a panel of trained smellers, and what the next steps are for digitizing the sense of smell. This week’s episode was produced with help from Podigy.
