Title: Secondary Teachers' Knowledge of Rate of Change

Speaker: Jihwa Noh

ABSTRACT

This study investigates experienced and less experienced secondary mathematics teachers' knowledge of rate of change in the context of teaching a Standards-based high school mathematics curriculum. Data were collected from 13 CPMP teachers using survey, mathematical task-based interview and classroom observations. Teachers' conceptions of rate of change differed based by experience with the CPMP curriculum. Results will be reported that curriculum materials may support teachers as they learn rate of change but that a more thorough understanding of the concept may require additional resources. Students who had elementary differential geometry or advanced calculus are encouraged to come to this talk.
