Motion
and Graphing
|
|
Prof. Ashby uses a "ranking task" to
determine student's prior knowledge of graphing data. She asks each participant
to determine, "which graph(s) of distance vs. time depict an object moving
at a constant rate..." |
Prof. Dowdy discusses the ranking
tasks that were used on the previous day's exam...

The introductory challenge to the class
groups was to generate a data set to measure speed using different methods
of locomotion. Rita Martin demonstrates her "side shuffle" technique as
Paul Ayers times her trial over a measured distance with a stopwatch. |
Distance vs. time data is recorded
to determine the speed of an individual...
|
The motion sensor is introduced
to the group.
|
Next the groups are asked to replicate
a graph that is displayed on the calculator using the motion detector.
The student graph is displayed in real time on the same screen with the
"model" line of distance (y-axis) vs. time (x-axis) |
Prof. Ashby assists individual groups
as they are begin to work with the motion sensor to collect motion data... |
