(To see what a better problem solving strategy would look like, skip to the bottom... )
Many problem solving strategies in math are problematic in themselves. Here are some typical problems with them:
(1) Some are too high level or abstract,
and thus provide little to no traction for students to get into
practically solving problems. Students either don't know what exactly
they should do, or they misunderstand the intent of a step in the
strategy.
e.g. one strategy calls for the student to describe any "barriers
or constraints that may be preventing them from achieving their goal".
Would "the teacher hasn't taught us" be a valid barrier? (The answer
could be "yes", by the way.)
(2) It assumes a pretty smart student,
rather than assume a barely passing one. So the strategy works great
for students who would've done fine without your help in the first
place.
