Abstract

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.

Summary

Introduction

The success of the learning process is largely determined by the ability of the teacher to manage the teaching and learning process. creating teaching and learning activities that are able to develop learning outcomes as much as possible is the task and responsibility of the teacher. Creating teaching and learning activities that are able to develop learning outcomes as much as possible is the task and responsibility of the teacher. According to Pupuh Faturohman, (2011: 13) the teacher is the spearhead in the teaching and learning process. Teachers who interact directly with students in the classroom, teachers play an important role in making students understand and understand about the learning being taught. The teacher places more emphasis on the task in planning and implementing the learning process of learning. Mathematics is one of the basic sciences which have an important role in efforts to master science and technology. Mathematics has an important role in various aspects of life. There are many problems and activities in life that must be solved by using mathematical science such as counting, measuring and others
