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.

Author/Source:
UC Museum of Paleontology

Grade level:
13-16

Time:
5-20 minutes

Teaching tips:
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.

Concepts:
Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.

  • Evolution is often defined as a change in allele frequencies within a population.

  • The Hardy-Weinberg equation describes expectations about the gene pool of a population that is not evolving—one that is very large, mates randomly, and does not experience mutation, natural selection, or gene flow.
