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.

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.

This study aims to identify types of errors made by students and their conceptions related to the concept of relations and functions. This research is a descriptive study with a qualitative approach conducted in eight grades at one of Madrasah Tsanawiyah in Kabupaten Bandung Barat. The research subjects were taken from 26 students who answered incorrectly on a given test. The research instrument was in the form of a diagnostic test based on basic competencies and indicators in the Relations and Function material. In-depth interviews were conducted with students who made mistakes in answering. Based on the data analysis, the mistakes made were: 1) conceptual error type 1, 2) conceptual error type 2, 3) procedural error, 4) technical error, and 5) error in understanding the problem. One of the causes of students' mistakes is the dissimilar concept between students’ and scientific conceptions.

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.

This study aims to determine the profile of self-confidence of students in level VIII of SMP Negeri 3 Cimahi. This study used a descriptive quantitative approach with data collection techniques in the form of a self-confidence questionnaire given to 74 students from two classes, namely classes VIII-F and VIII-A. The results showed that the profile of self-confidence in level VIII students of SMP Negeri 3 Cimahi based on aspects of confidence in their abilities, most students were in the high category, as many as 39 students with a percentage of 53%. Meanwhile, of the five aspects that are most in the very low category, namely in the rational and realistic aspects, there are 13 students with a percentage of 18%. based on the results of the graph, it shows that female students are more in the very low category, totaling 7 while male students are 4 in the very low category. In addition, the difference between classes based on the results of the graph shows that class VIII-A with a percentage of 50.7% and class VIII-F 49.3%. Looking at these results confirms that there is a need for customized strategies to increase student confidence, according to the unique conditions of each class.

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.

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.
