Abstract

This study investigates the effect of the use of teachers? Lecture models combined with cooperative learning methods to improve students? problem-solving skills in physics compare with the control group who were not exposed to the lecture model combined with cooperative learning methods from effect size value. The research method was a quasi-experimental research. The sample consisted of 33 students of 10th grade in middle schools (senior high school), SMAN 1 Sungai Penuh, Jambi Province where they ware learn at work and energy concept. Students' achievements, as well as their problem-solving skills of work and energy concept were assessed by pretest-posttest with an essay test. The results showed that the experimental group?s learning process has a high effect size value to problem-solving skills more than control group learning process. That shows the lecture model combined with cooperative learning method more effective than lecture model.

Abstract

This research aims to analyze the profile of students’ problem-solving ability in problems of optical instruments. This survey research involved 65 students class XI of MAN 3 Yogyakarta. The research instrument was in the form of 3 problem-solving questions in the form of a description. The results showed the percentage of students in the expert category was still relatively low at 30,7% and the students in the novice category were quite high at 69,3% so that students’ overall physics problem-solving abilities were relatively low. In this research, some student difficulties were still found, one of which was in determining the focus of the right lens for patients with eye disorders to use glasses and determine magnification when using a magnifying glass. Efforts to implement innovative learning are needed to improve problem-solving abilities in overcoming students’ physics problems.
