I’m not sure what your question is exactly. I see the step size as the rate
of x amount of steps per second. If a runner takes a step size of 1 (step per
second) it will take him 100 seconds to run the 100 yards. If the runner takes
a step size of 2, it will take him 50
seconds to run the 100 yards. The students can experiment changing the step
size (rate) and come up with various conclusions using the applet.
Maybe the label should be changed to steps per second to make it clearer,
but with experimentation, students can and do pick up the idea behind the step
size and see what happens when they change this rate.
