Overview

This set of two PowerPoint slides featuring questions for problem-based discussion (i.e., open-ended questions that engage students with each other and with course material) can be easily incorporated into lectures on populations genetics.

  • [Mechanisms of evolution: Grades 13-16] Evolution is often defined as a change in allele frequencies within a population.
  • [Mechanisms of evolution: Grades 13-16] The Hardy-Weinberg equation describes expectations about the gene pool of a population that isn't evolving, that is large, mates randomly, doesn't experience mutation, natural selection, or gene flow.

There are no NGSS/DCI concepts currently linked to this resource.

With increased experience, the instructor will be able to develop additional problem-based discussion questions, optimizing them for particular applications and topics. To learn more about how problem-based discussion and other types of active-learning activities can be easily incorporated into lecture (and for more downloadable slides!), visit our guide to active learning in the undergraduate classroom.
