Re: [Phys-L] Evaluation tests



We are looking for something to use as a way to meter out which students take our accelerated path in science. Our standard path is freshmen: Physical Science (1 semester physics, 1 semester chem); sophomores take general biology; juniors take chemistry; seniors take physics. Our accelerated path has students skip physical science so their junior year is either ap physics or ap biology. THen their senior year can be an additional ap course or other science electives.
Our challenge is that we have students come to us from different schools (out of district) some of which are private schools. Since there is such a wide variation in what the kids do in their different schools, we are looking for a standard exam that we can use to determine students abilities.
I was hoping to use the Lawson test, but I don't know that the mc version (which is what we would use for time management) is useable for students ending their 8th grade year.
We are looking at other exams, but I want to stay away from counter-intuitive gotchas and stick with things that check the students reasoning abilities and so on.

Have a good one.
Paul.

Right, but still I'd be tempted to look at the data to see if, say, the
average of their grades in chemistry and algebra did a better or worse
job predicting their results in physics than the test you use. After
all, while physics is different than either chemistry or algebra, it is
also different than the arithmetic class where we hope they would have
learned about fractions.

I'm at a private school and physics is an elective. Many are encouraged to
take physics to have all three foundation courses for college. To me, the
"placement" test is a useful thing. I've had juniors do poorly on it, drop
physics, and take physics again as seniors -- and do very well.

And as I've said before, physics is unlike any course a student will
ever take. It requires a different way of thinking, and some kids
simply don't have the proper skills to do well. And "working hard"
is sometimes not enough.

Taking that to heart, I wonder if these tests are worth giving. If the
goal is to do a service to students who sign up but with little chance
of earning a c or better, I suspect that there is a lot of information
available with more predictive power: grades in previous science
classes, high school gpa, even math SAT score might do a better job than
what has been proposed so far. But to find out, you would have to check
the data.

But I am not sure that is our role to make these predictions. If a
student has a destination in mind and physics is one of the requirements
along the way, then despite what my (admittedly fuzzy) prediction model
would say, my first instinct is to say come on in and be prepared to
work hard.
