Abstract
This study investigated the effects of problem-solving teaching method on elementary school students’ physics achievement at elementary school. In this investigation an experimental research procedure was used. Along with this, a sample of sixty students was drawn from a total of three hundred seventy-eight students using lottery method of sampling technique. Physics achievement test (pre-test and post-test) covering the unit ‘’Introduction to Electronics’’ was used as measuring instrument. Then, based on the pre-test scores, mixed ability groups such as fifteen high and fifteen low scoring 30 students each were assigned as experimental (13Fand17M) and control(15 and15M) groups using lottery method of sampling technique Students in the experimental group were taught using problem solving teaching method while those in the control group were instructed with lecture teaching method. The post-test constructed by the writer in the sample unit taught was administrated to both groups immediately after the treatment was over. Finally, the results of the study revealed that problem-solving teaching method was more effective in teaching physics as compared with lecture method at elementary school level.

Highlights
Physics is a science subject that deals with matter, energy, motion and force
The results of this study made clear that there was a high statistical significant difference between the mean scores of physics students who were taught by problem-solving approach and those instructed by lecture method
Students in the control group achieved low mean score in the unit taught as compared with the achievement of students in the experimental group for the following reasons: solving problems individually; no exchange of information with friends; hesitating to ask unknown concepts or questions to teachers or friends; committing careless mistakes that went against physics laws; teacher-centred instruction etc
Summary
Learning Physics is important as it is one of the fields of knowledge that underlies the physical universe and applies constantly to people’s everyday lives. The main objective of education is to prepare an individual for better life through cultivating his/her capacity for problem-solving and adaptability to the environment by developing the necessary knowledge, skills and attitudes. In this case, student-centred method involves students in doing things, interacting, discussing, debating and asking questions, exploring, experimenting and thinking about the things they are doing and observing their own knowledge through active participation. The study may contribute to promote an active learning strategy of constructivist approach
