YES.  More generally, in teaching math classes I've found it's usually *well*
worth the time spent teaching metacognitive skills, because many students
haven't ever really spent time analyzing their process of solving a problem
(or even answering basic academic questions like, "How do I decide what to
write in my notes?" or "How can I be confident I understand what happened in
class today?").  I don't have the research handy, but I remember encountering
some work a few years back that seemed to corroborate my experience.
