Abstract
The problem in this study is how the effectiveness of learning with Peer Lesson and conventional methods on subject matter of plane figure in class VII-A junior high school Kesatria Medan. The research method used is a quasi experiment with research samples namely classes VII-A and VII-B junior high school Kesatria Medan with each class having 30 students with a pretest and posttest control group design research. The instrument used in this study was a problem solving ability test. Based on the research results, it is known that peer lesson (experimental class) is better than conventional method (control class) as seen from the difference between the pretest and posttest results for experimental class is 4.87 and control class is 3.04. Then the gain value is 0.70 with the high category for the experimental class and 0.45 with the moderate category for the control class. Therefore there is a difference between the problem-solving abilities of students with Peer Lesson and students who use conventional methods on the subject of plane figure in class VII junior high school Kesatria Medan.
