Application of Problem Based Learning Models to Students' Mathematical Problem Solving Ability

摘要

Student problem solving abilities are still low because of the lack of response of students' feedback to the teacher's questions and explanations, and the lack of concentration on mathematics. The cause of the problem is the lack of problem solving abilities of students in mathematics learning, and variations in the application of learning models. This study aims to analyze the effect of the application of problem-based learning models on mathematical problem solving abilities of students at SMAN 7 Padangsidimpuan. The type of experimental research consisted of case groups (problem based learning methods) and controls (question and answer method), with a 2x3 factorial design. The population in the study is the student at class X SMAN 7 as many as three classes with a total of as many as 34 students / class. The research samples were class X-2 and X-3, with random sampling techniques. Techniques in collecting data through tests, observations, and interviews. Statistical analysis was performed using t test analysis. The results showed that the problem-based learning model was better than through the application of direct learning, with the average results of the experimental class students being 80.74 and the control class 68.24. The application of problem-based learning to improve students' problem solving skills can be carried out by teachers in the dual improvement of the quality of education in schools.
