Exploring Rate of Change through Technology with Elementary Students
American Educational Research Association Annual Meeting,
The purpose of this study was to investigate students developing understanding of concepts related to rate of change. Twenty students first participated in a rate of change curriculum unit as part of an after school math and technology program. During the unit, students used motion detectors and related graphing software to create and analyze graphs of changing positions and velocities. They then explored change in a banking context using an interactive diagram called Bank Account. The results of this study suggest that early introduction to rate of change concepts is valuable--elementary students are clearly capable of thinking about and understanding concepts related to rate of change.
