The aim of this research is to investigate the effects of problem solving strategies instruction on the students' physics problem
solving performance and strategy use. In this research, semi-experimental research design with a pretest-posttest control group
was used. The data of this research were collected by a “Written Physics Examination” and the use of “Physics Problem Solving
Strategies Scale”. At the end of the research, it was determined that the problem solving strategies instruction had positive effects
on the physics problem solving performance and strategy use, and suggestions related to the results were put forward.
