(If this has been addressed in other discussions, I apologize). I can take
loooong steps very slowly or short steps very quickly, so I don't like the
assumption that increasing step size will cause the "runner" to get there
faster. If the xaxis scale were in "number of steps" instead of "time," this
would make sense.
One of the sessions I attended at NCTM in ATL was about the shortcomings of some
electronic manipulatives and how these could lead to misunderstandings about the
mathematical concepts. Distance = RATE * time, not LENGTH OF STEP * time.
