Our guest this week is Tim Hartelt from the Department of Biology Education at the University of Kassel in Germany. With colleagues Helge Martens and Nina Minkley, Tim recently co-authored a study investigating if science teachers were able to diagnose the alternative conceptions the may hold when teaching biology concepts. Tim joins us to discuss the study and its findings, how teachers might identify alternative conceptions, and explain how they might be connected to their own professional experiences and content knowledge.
