Abstract

Matematika merupakan salah satu bidang ilmu yang dianggap sulit oleh kebanyakan siswa, sehingga tidak sedikit siswa yang memperoleh hasil belajar matematika yang rendah. Penggunaan media pembelajaran dapat membantu siswa dalam memahami konsep matematika yang pada akhirnya dapat meningkatkan hasil belajarnya. Penelitian ini mengkaji mengenai penerapan media software GeoGebra pada pembelajaran topik lingkaran di suatu Sekolah Menengah Pertama (SMP) di Jakarta dan mendeskripsikan tentang bagaimana hasil belajar siswa dapat meningkat melalui pembelajaran tersebut. Penelitian ini berjenis kualitatif deskriptif dengan teknik analisa data model Miles dan Huberman dan melalui proses triangulasi data. Hasil penelitian ini menunjukkan bahwa penerapan media software GeoGebra dapat membantu siswa dalam memahami materi pada topik lingkaran, sehingga hasil belajar siswa meningkat sebesar 30%.

Abstract

Previous research shows that seventh-grade students lack a sense of flexibility about numbers, lack comprehension of the effect of the operation on numbers, and lack estimation skills. On the other hand, writing to learn is one of the learning activities where the students actively write to express themselves in learning specific material/topic. This project aims to develop a learning module for students about the integers by utilizing the basic number sense framework: the six strands of number sense (Mcintosh et al., 1997) and combining it using writing to learn mathematics (Burns, 1995). The module developed using the steps proposed by Purwanto (2007) and then validated by the experts and tested to the subjects’ trial. The module was then validated by three experts who are lecturers at Sampoerna University. After validation, the module was then tested on four seventh-grade students, where the data gathered by both observation and group interview. As a result, all participants agree that the learning module is easier than what they taught at school and would recommend the module to their friends.

Abstract

The study's objective is to investigate common difficulties experienced by 8th-grade students when solving non-routine mathematics problems. This study used a qualitative descriptive method, and the research participants were eighth-graders students at one of the private middle schools in Jakarta. The researchers used a convenience sample to obtain a group of six students available for an in-depth interview session and willing to solve two non-routine problems related to algebra topic. The study showed that the participants experienced difficulties when solving non-routine mathematics problems. They could not read the problem comprehensively; they had trouble converting the word problems into mathematical sentences. They also had difficulty in carrying out their plans. In other words, students did not have the strategy to solve the problem. They had errors in the calculation and had incorrect formulations when solving the given problems. It is suggested that the teacher provide students with guiding instructions to assist students in going through the problem-solving phases step by step. The teacher can also highlight the non-routine problem's keywords and give a representation that helps students understand the problem. Keywords: learning difficulties, middle school students, mathematics problems DOI: http://dx.doi.org/10.23960/jpmipa/v23i1.pp67-77
