Dialogue

|
Teacher:
|
In my class, I did the six blocks problem -- that's the one where
students try to make as many velocity graphs as they can which occupy
six blocks of area. And then they discuss what is the same, and
what is different about each graph, right?
|
|
Mentor:
|
Could you show me some of the
things your students did?.
|
|
Teacher:
|
Well of course, one student made
a graph that is 6 units high, and 1 second long.
(demonstrates to Mentor This
simulation goes very fast for a short while. )
|
|
Mentor:
|
I see. Uh-huh.
|
|
Teacher:
|
And another student made a
graph that is 3 units high for 2 seconds long, like this.
(demonstrates to mentor, reset,
run simulation).
|
|
Mentor:
|
Mentor: And what did they say
is "different" and "the same" about those two
situations.
|
|
Teacher:
|
It took them a while
to notice that all the graphs go to six meters. But they quickly
noticed the different speeds. Not many of them noticed the elapsed
time.
