The CBEST was instituted for political reasons, not ed.

I agree, passing appropriate courses is a considerably better qualification.

bc, even w/ a PhD in Physics (and extensive college teaching) can’t teach it in a public HS.

Is this example meant to be ironic? Which of these kids is going to learn fractions today? :)

More seriously, though: if you believe that it is important that elementary school teachers can do a little algebra, putting one or two items on a multiple choice test is not going to make that happen. You'd be better off requiring that they have one college level course in a subject that uses algebra, one that they'd be unlikely to pass without that minimal level you were hoping to see.

Aaaagh!

You’re correct, however, this practice exam. includes one, I think — at least I used algebra , #22

At the beginning of a class period, half of the students in a class

go to the library. Later in the period, half of the remaining

students go to the computer lab. If there are 8 students remaining

in the class, how many students were originally in the class?

It is interesting to note that Singapore students are expected to solve such problems in the third grade with their bar models.
