  Understanding issues involved in expertise in physics problem solving is
important for helping students become good problem solvers. In part 1 of this
article, we summarize the research on problem-solving relevant for physics
education across three broad categories: knowledge organization, information
processing and cognitive load, and metacognition and problem-solving
heuristics. We also discuss specific strategies discussed in the literature for
promoting development of problem-solving skills in physics. This review article
can be valuable in helping instructors develop students' problem-solving,
reasoning, and metacognitive skills in physics and other related disciplines.
Additionally, this review article is relevant across educational contexts in
countries that may have different educational paradigms and challenges.
