Abstract

The ability to solve problems is an essential skill that students must have in everyday life and as an integral part of the math curriculum. The research aims to achieve and improve the mathematical problem-solving ability of junior high school students through the application of the STAD (Student Teams Achievement Divisions) cooperative learning model. The method used is a quasi-experimental design experiment. The results of the study found that before the implementation of the STAD model, students' mathematical problem-solving skills were still low, as seen from the results of the pre-test. This study concluded that cooperative learning STAD is effective in achieving and improving the mathematical problem-solving ability of junior high school students.

Abstract

This research aims to analyze the learning of class VIII students at Nur Al Rahman Middle School in Cimahi City on linear equations of two variables system material using a scientific approach. In learning mathematics using a scientific approach, especially in linear equations of two variables system material, it is hoped that students can play an active, creative, skilled, and noble character, find and solve problems. The research method used was classroom action research with the subjects studied being 15 class VIII students. This research was conducted for 2 cycles with data collection techniques, namely observation, documentation, and tests in the form of essays that match the indicators of mathematical problem-solving ability. The increase in students' mathematical problem-solving abilities can be seen from the achievement of the percentage of test questions on the problem-solving abilities of the 2 cycles carried out. The instrument used in the research results found that the problem-solving ability skills in linear equations of two variables system material were 33% for cycle I, then 80% in cycle II. This means that learning mathematics in linear equations of two variables system material using a scientific approach has a better influence on students' mathematical problem-solving.

Abstract

This research is a study that focuses on the development of realistic-based mathematics teaching materials on high school students' mathematical communication skills on sequences and series material. Research and Development (R&D) is the research used, the model to support this research is using the ADDIE model which has 5 stages in its application, the stages of analysis, design, development, implementation, and evaluation. However, the discussion in this article only extends to the practicality test which is the advanced stage of the Development stage. The instrument used in this study was a questionnaire (validation and response). Validation was carried out by material experts, ICT experts, and responses were obtained from teachers and students. Material expert validation results reached a percentage of 85.10% of the average interpretation of "very feasible", ICT expert validation results were at 83.80% with the final statement "Very Feasible", student and teacher responses in the product test were obtained successively of 85.62% ("Very Practical") and 94.38% ("Very Practical"), the conclusion is that the mathematical material based on canva-assisted realistic is "Very Appropriate" and "Very Practical" in use for learning mathematics in senior high school.

Abstract

Penelitian ini dilatarbelakangi oleh rendahnya tingkat belajar siswa dipengaruhi oleh persepsi mengenai pembelajaran matematika yang dianggap sulit. Siswa harus mengembangkan pengetahuan baru mereka secara aktif dari pengalaman dan pengetahuan sebelumnya sehingga dibutuhkan kemampuan High Order Mathematical Thinking (HOMT) siswa SMP. Untuk mengatasi permasalahan tersebut diperlukan salahsatu model  pembelajaran  yang  diharapkan  mampu  mengembangkan kemampuan High Order Mathematical Thinking (HOMT) siswa  adalah pembelajaran worksheet berbasis ICT. Melalui pembelajaran ini terdapat lembaran-lembaran berisi tugas instruksional yang terdiri dari serangkaian pertanyaan dan informasi yang dirancang berbasis ICT untuk membimbing siswa agar memahami masalah matematika yang memuat soal-soal sistematis bertujuan meningkatkan High Order Mathematical Thinking (HOMT) siswa. Metode penelitian yang digunakan adalah  quasi experimental dengan bentuk desain Nonequivalent Control Group Design, dimana subyek penelitian tidak dikelompokkan secara acak. Data dalam penelitian ini dikumpulkan melalui pretes dan postes  kemampuan  HOTM siswa.Tujuan dalam penelitian ini adalah mengkaji pencapaian dan peningkatan kemampuan high order mathematical thinking (HOMT) siswa SMP  di kelas yang mendapat pembelajaran Worksheetberbasis ICT  lebih baik daripada siswa di kelas yang mendapatkan pembelajaran ekspositori.Hasil dari peenlitian ini adalah peningkatan kemampuan HOTM siswa SMP yang menggunakan pembelajaran worksheet berbasis ICT lebih baik dibandingkan kelas yang pembelajarannnya menggunakan ekspositori.

Abstract

The purpose of this study was to improve students mathematical literacy skills in statistics by appliying the Contextual Teaching and Learning (CTL) approach. Students of SMP Negeri 2 Padalarang became the population in this study. Thirty students of class VIII-A served as the experimental group and thirty students of class VIII-I served as the control group. This study used a non-equivalent control group design with quasi-experimental research methodology. This study included pretest, action, and posttest. This research tool used a written test to collect information about the improvement of students’ mathematical literacy skills. Data analysis was carried out by conducting normality test, homogeneity test and mean test in order to obtain conclusions. The findings of this study show that the improvement of mathematical literacy skills of students whose learning uses the Contextual Teaching and Learning (CTL) approach is better the those who use ordinary learning.

Abstract

This research aims to examine the enhancement of mathematical problem-solving skills and the application of learning through the RME approach with the assistance of VBA Excel. The method used in this research is a quasi-experimental design with a pretest-posttest control group involving two groups of students: the experimental group, which received treatment through the RME approach assisted by VBA Excel, with the outcome observed being the students' mathematical problem-solving abilities. Meanwhile, the control group received instruction using the conventional approach. The population in this study is all eighth-grade students at SMP Negeri 4 Cimahi. The research sample consists of two randomly selected classes, namely the experimental class with 30 students and the control class with 30 students at SMPN 4 Cimahi. The instrument used consists of four open-ended questions assessing mathematical problem-solving abilities on the topic of the Pythagorean theorem. Data analysis was conducted using normality tests, homogeneity tests, and t-tests. The research results indicate that the Realistic Mathematics Education (RME) approach assisted by VBA Excel can enhance students' mathematical problem-solving abilities compared to the conventional approach in the learning process.

Abstract

Algebra is one of the essential branches of mathematics that often presents challenges for students, especially when faced with inverse function problems. This study aims to describe algebraic reasoning in solving inverse function problems from the perspective of students' mathematical resilience. This qualitative research uses a case study design involving 33 eleventh-grade students from a public high school in West Bandung Regency. The instruments used were a mathematical resilience scale and an algebraic reasoning test. Data analysis was conducted through data reduction, presentation, and conclusion drawing. The results showed that 15.15% of students had low resilience, 72.72% had moderate resilience, and 12.12% had high resilience. There were different characteristics in algebraic reasoning among students in these resilience categories. The implications indicate that targeted learning strategies can enhance algebraic reasoning, especially for moderate and low-resilience students.
