Day 7 clip 1:
Exploring Distance From Bridge as a
Function of Time
Dr. Thompson then agrees to teach the lesson
on Day 7 in which he revisits the bungee
jumping task, but changes the quantity on
the vertical axis from distance
from the ground to distance
from the bridge.

Day 7 clip 2:
Exploring Distance From Bridge as a
Function of Time
In the clip shown here, Ms. Coombs works
one-on-one with a student who is trying to
use the finger tool to show the relationship
of the bungee jumper's distance from the
bridge as a function of time. What you see
here is two minutes of a nine-minute
exchange where Ms. Coombs encourages the
student to think about relative changes.
This exchange occurs as Dr. Thompson is
working with the rest of the class.

Day 7 - Clip 1
Exploring Distance From Bridge as a Function of Time
Dr. Thompson then agrees to teach the lesson on
Day 7 in which he revisits the bungee jumping
task, but changes the quantity on the vertical
axis from distance from the ground to distance
from the bridge. The horizontal axis remains the
jumper’s elapsed time from the the beginning of
his jump. In this context, students must co-vary
the quantities’ values instead of just
envisioning the path of the jumper.
