Abstract

Mathematics is one of the subjects taught at all levels from basic education to higher education, which has a significant role in preparing students to have the ability to think logically, analytically, systematically, critically and creatively, as well as have the ability to work together. One of the activities in learning mathematics at school is through problem solving. Problem solving aims to see students' understanding of a material. Mathematical problem solving ability is a very important part of learning mathematics. However, in reality, the problem-solving ability of junior high school students' mathematics is still very low. From these problems, then one of the lessons that can improve the ability to solve mathematical problems is Problem Solving learning. One of the factors that influence differences in problem solving ability is learning style. Learning styles have a close relationship and influence on the learning process in order to achieve learning goals. With students knowing their learning style, learning Problem Solving can be done easily. The subjects of this study were students of class VIII A MTs Plus Sunan Drajat Kedungsantren Bojonegoro. The purpose of this study was to determine the effectiveness of Problem Solving learning on mathematics learning outcomes when viewed from students' learning styles. The type of research used is quantitative research with the One Group Pretest-Posttest Design. The results showed that testing the data on mathematics learning outcomes with the Paired Sample T-Test stated that the t_count value was -9.726. The t_count value is negative, because the pretest average value is lower than the posttest average value. In this case, the t_count value can be positive so that it becomes 9.726. Meanwhile, the value of t_table with α = 0.05 and degrees of freedom (dk=n-1) with 24 students is 1.714. Then it can be seen that t_count > t_table, then H0 is rejected and Ha is accepted, meaning that there is a significant difference. So it can be concluded that the application of the Problem Solving learning model is quite effectively carried out in the teaching and learning process for class VIII A students of MTs Plus Sunan Drajat Kedungsantren on the material of geometric shapes on the flat sides of cubes and blocks.

Abstract

Abstrak: Geometri adalah salah satu cabang ilmu matematika yang berkaitan dengan titik, garis, bentuk bidang dan ruang. Geometri yang berkaitan dengan bentuk ruang adalah materi bangun ruang, terkhusus yang akan dibahas adalah bangun ruang kubus. Dalam belajar bangun ruang kubus pasti akan menemukan suatu masalah, oleh karena itu kemampuan menyelesaikan masalah adalah suatu cara yang tepat untuk meningkatkan kualitas siswa dalam memahami materi bangun ruang kubus. Penelitian ini bertujuan untuk mengetahui bagaimana kemampuan siswa dalam menyelesaikan masalah matematika, khususnya bangun ruang kubus berdasarkan teori Polya. Penelitian ini menggunakan metode pendekatan deskriptif kualitatif. Teknik pengumpulan data yang digunakan adalah dengan tes kemampuan siswa dalam menyelesaikan masalah berupa pemberian soal dan wawancara. Berdasarkan hasil analisis diperoleh bahwa tingkat kemampuan siswa dalam menyelesaikan masalah matematika pada materi bangun ruang kubus berdasarkan teori Polya adalah “baik”. Siswa dapat menyelesaikan masalah dengan cara mengidentifikasi masalah, merencanakan penyelesaian masalah, menyelesaikan masalah, dan memeriksa kembali. Dari hasil tersebut dapat disimpulkan bahwa siswa dapat terbantu dalam menyelesaikan masalah matematika pada materi bangun ruang kubus berdasarkan teori Polya. Kata kunci: Menyelesaikan Masalah; Kubus; Teori Polya. Abstract: Geometry is a branch of mathematics that deals with points, lines, shapes and spaces. Geometry related to the shape of space is the material of building space, especially what will be discussed is the shape of a cube. In learning to build a cube, you will definitely find a problem, therefore the ability to solve problems is the right way to improve the quality of students in understanding the material for building cubes. This study aims to determine how the students' ability to solve mathematical problems, especially to build a cube based on Polya's theory. This study uses a qualitative descriptive approach. The data collection technique used is to test students' ability to solve problems in the form of giving questions and interviews. Based on the results of the analysis, it was found that the level of students' ability to solve mathematical problems in the material of building a cube based on Polya's theory was "good". Students can solve problems by identifying problems, planning problem solving, solving problems, and checking again. From these results it can be concluded that students can be helped in solving mathematical problems in the material of building a cube space based on Polya's theory. Keywords: Solve the problem; Cube; Polya's Theory
