On problem with this quiz is that it does not really hit the sorts of things
that students need to know. For example can they order mixed fractional and
decimal values all of which are less than 1?
Then there is the admonition to give numerical answers. Math teachers would
consider 5 sqrt(2) to be a numerical answer. Would fractional answers also
be acceptable? I think they want decimal answers, but that is not spelled
out.
It does not properly test proportional reasoning, or 2 variable reasoning,
both of which are vital to understanding physics. One can give seemingly
simple questions which test the important things without giving very
complicated problems. I see this test as being skewed towards things that
will not evaluate whether students have the necessary paradigm and thinking
to be able to do physics well.
