Time: 2 minutes
This set of two PowerPoint slides featuring personal response questions (i.e., multiple choice questions that can be used with "clicker" technology) can be incorporated into lectures on the mechanisms of evolution in order to actively engage students in thinking about evolution.
- [Mechanisms of evolution: Grades 13-16] Smaller populations are more strongly affected by genetic drift than are larger populations.
- [Mechanisms of evolution: Grades 13-16] Genetic drift can cause loss of genetic variation in a population.
- [Mechanisms of evolution: Grades 13-16] Founder effects occur when a population is founded from a small number of individuals.
- [Mechanisms of evolution: Grades 13-16] Founder effects can affect the genetic makeup of a newly started population (and reduce its genetic variation) through sampling error.
There are no NGSS/DCI concepts currently linked to this resource.
With increased experience, the instructor will be able to develop new personal response questions, optimizing them for particular applications and topics. To learn more about how personal response questions 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.
