110- Talking about Change: Studentsí Understandings of Negative Rates of Change

Tuesday, April 16, 2013: 4:45 PM-6:00 PM
Lobby A (Colorado Convention Center)
Lead Speaker:
AnnMarie H O'Neil
Jonas B Arleback

Description of Presentation:

We report on the development of studentsí abilities to represent and interpret negative average rates of change. Students confused function values and rate values and often focused on the magnitude of the change rather than its signed value. Everyday language conflicted with formal mathematical language for describing negative rates of change.
