Good problem-solvers regularly and consciously reflect on and monitor their own thought
processes. By doing so, they are able to recognize when the technique they are using is
not fruitful, and to make a conscious decision to switch to a different strategy, rethink the
problem, search for related content knowledge that may be helpful, and so forth. Students’
problem-solving skills are enhanced when they reflect on alternative ways to perform a
task even if they have successfully completed it. Reflecting on the reasonableness of an
answer by considering the original question or problem is another way in which students
can improve their ability to make sense of problems.
