Sample
Overview
The sample investigation
below is the first investigation of the unit. In this investigation,
students are asked to think about the problem of estimating the rate
of change at a specific point in time for three continuously changing
phenomena—height of a bungee jumper, motion of a person walking
toward and away from a motion detector, and profit of a business. In
each case, they are asked to use graphs and tables of sample values for
each variable to estimate instantaneous rates of change.
Instructional
Design
Throughout the curriculum,
interesting problem contexts serve as the foundation for instruction.
As lessons unfold around these problem situations, classroom instruction
tends to follow a fourphase cycle of classroom activities—Launch,
Explore, Share and Summarize, and Apply. This instructional model is
elaborated under Instructional Design.
