What does CBR do?
With
CBR
and a TI graphing calculator, students can collect, view, and analyze motion data
without tedious measurements and manual plotting.
CBR
lets students explore the mathematical and scientific relationships between distance,
velocity, acceleration, and time using data collected from activities they perform. Students
can explore math and science concepts such as:
0
motion:
distance, velocity, acceleration
0
graphing:
coordinate axes, slope, intercepts
0
functions:
linear, quadratic, exponential, sinusoidal
0
calculus:
derivatives, integrals
0
statistics and data analysis:
data collection methods, statistical analysis
What’s in this guide?
Getting Started with CBR
é
is designed to be a guide for teachers who don’t have extensive
calculator or programming experience. It includes quick-start instructions for using
CBR
, hints
on effective data collection, and five classroom activities to explore basic functions and
properties of motion. The activities (see pages 13–32) include:
0
teacher notes for each activity, plus general teacher information
0
step-by-step instructions
0
a basic data collection activity appropriate for all levels
0
explorations that examine the data more closely, including what-if scenarios
0
suggestions for advanced topics appropriate for precalculus and calculus students
0
a reproducible student activity sheet with open-ended questions appropriate for a wide
range of grade levels
