Today our guest is Dr. Michelle Herridge, post-doctoral fellow in stem education with the Academy for Teaching and Learning at Baylor University. Dr. Herridge has earned her PhD at the University of Arizona in chemistry with a minor in teaching and teacher education. She has worked in discipline-based education research since 2013 and has a BS in chemistry and a BS in sociology from Clemson University and an MS in chemistry from Missouri State University. Her research explores assessment and instructional practices, primarily in chemistry education and professional development for graduate teaching assistants and new faculty. She has taught in a variety of courses including Baylor Interdisciplinary Core’s Natural World Sequence, a science and integration course for pre-service teachers. We are delighted to have Dr. Herridge on the show to discuss recent developments in discipline-based education research, what excites stem college instructors, and what it's like to teach outside your area of expertise.
