Abstract

AbstrakPenelitian ini merupakan penelitian tindakan kelas (PTK) dengan tujuan mengetahui pengaruh pendekatan kontekstual terhadap peningkatan pemahaman matematis siswa. Subjek dalam penelitian ini  adalah siswa MTs pada salah satu sekolah di Cimahi sebanyak 20 orang siswa. Penelitian ini dilakukan untuk mengetahui sejauh mana siswa mampu memahami pembelajaran materi SPLDV dengan menerapkan pendekatan kontekstual. Penelitian ini dilakukan menggunakan model penelitian spiral dimana penelitian akan dihentikan jika peneliti sudah mendapatkan tujuannya. Peneliti melakukan 2 siklus pembelajaran yang pada setiap siklusnya peneliti dinilai oleh observer. Hasil penelitian ini menunjukan bahwa dalam siklus 1 aktivitas guru memperoleh predikat baik namun, aktivitas siswa masih dalam kategori kurang. Sehingga hasil ketuntasan siswa dalam belajar masih dibawah KKM. Oleh karena itu, peneliti melakukan siklus 2 dimana pada siklus ini terjadi peningkatan baik aktivitas guru, siswa, maupun ketuntasan belajar siswa. Yang memperoleh predikat sangat baik dan baik.  AbstractThis research is a Classroom Action Research with the aim of knowing the influence of contextual approaches on improving students' mathematical understanding. The subjects in this study were MTs at one of cimahi's 20 schools. This research was conducted to find out the extent to which students are able to understand spldv material learning by applying a contextual approach. This study was conducted using a spiral research model where the research will be discontinued if the researcher has got his goal. Researchers conducted two learning cycles that each cycle was assessed by the observer. The results of this study showed that in cycle 1 teacher activity obtained good predicate however, student activity is still in the category of less. So the results of students' completed learning are still under KKM. Therefore, researchers conducted cycle 2 where in this cycle there was an increase in both teacher activity, students, and student learning completeness. Who earned a very good and good predicate.

Abstract

This research aims to determine the feasibility, practicality and effectiveness of the product being developed. The product developed is a Student Worksheet (LKPD) on flat-sided building materials based on an assisted scientific approach GeoGebra. This research uses the method Research and Development (R&D), the 4D model according to Thiagarajan is limited to 3 stages, namely definition, design and development. The instruments used are test and non-test instruments. Data is processed using Microsoft Excel 2010. The subjects in the research were class VIII students at one of the Cimahi State Middle Schools, totaling 36 students in the limited trial and 72 students in the wide trial. The feasibility of the LKPD developed during validation obtained very valid results. The results of the practicality test in the limited trial were categorized as practical and in the extensive trial it was found to show the very practical category. The results obtained from the effectiveness of the LKPD showed that it was in the very effective category. Based on the research conducted, the results of the LKPD are shown flat-sided spatial building material based on an assisted scientific approach GeoGebra declared feasible, practical and effective for use.

Abstract

The aim’s of this research is to determine the increase in students' mathematical problem solving abilities using the discovery learning model. The research method used uses quasi-experimental techniques. The subjects of this research were 30 students at Kahuripan Lembang Middle School, class VIII-C. Data collection techniques through test questions and LKPD with discovery learning model stages. The data obtained was then analyzed quantitatively using the difference between two means test. The results of the research show that students' mathematical problem solving abilities use the discovery learning model for class VIII middle school because the learning activities carried out make students think more systematically, critically, creatively in solving the problems given, so that they can improve students' mathematical problem solving abilities.

Abstract

The purpose of this study was to determine the increase in mathematical problem solving abilities of students who received the discovery learning model with students who received ordinary learning. The research method used was quasi-experimental. The population in this study were students of class VIII MTs Al-Furqon located in Cisarua, West Bandung with samples taken as many as two classes. The experimental class received learning by applying the discovery learning model, while the control class received ordinary learning. Data collection techniques by giving pretests and posttests. Quantitative data processing techniques were processed using MS Excel and SPSS. The results showed that students had the ability to solve mathematical problems when they learned to apply the discovery learning model.

Abstract

Cognitive mathematics games are an innovative tool to enhance student engagement by visualizing abstract mathematical concepts, which are often perceived as difficult, into something easier and more enjoyable. The goal is to help students realize that mathematics is not something to be feared, but rather a challenge that they can solve on their own. By using cognitive mathematics games, the interaction between teachers and students in the classroom becomes more conducive and enjoyable. This media is designed using Pygame and PygZero, which are game development applications in Python programming, making it easier for anyone — including educators, teachers, and lecturers — to create the media. The media was introduced to students of SMA Negeri Rongga in West Bandung as a trial in the development of cognitive mathematics games, where it served as a motivational tool to stimulate students’ logical thinking processes in solving problems through gameplay. Examples of the games introduced to students include the Tower of Hanoi and Frog Jump, both of which are linked to mathematical concepts as the final solution. At the end of the community service activity, students gave positive feedback on the use of the cognitive game media
