Abstract

This study aims to determine the quality of the test items for mathematics subjects on the material of a two-variable system of linear equations with a combined method. That the thing is that learning is limited by researchers will conduct research at SMP Negeri 2 Haurwangi with research subjects of class VIII students who are in class 05 which contains 17 students. In class 05, students have different characteristics, from high, medium, and low categories which can be obtained from the assessment of students' answers to the test questions given. The items made consist of 3 questions. With easy, medium, and difficult categories. Given this research is a research that uses quantitative descriptive which will be analyzed using Ms. Excel based on Validity, Reliability, Distinguishing Power and Difficulty Index. The results showed that; 1) the three items with very high validity and high reliability, 2) based on the discriminatory power of interpretation is less, 3) based on the difficulty index of question no. 1 and 2 are moderate, while question no. 3 is difficult.

Abstract

Being able to think creatively is crucial for kids since creativity is required to address difficulties. The purpose of this research was to find out the characteristics of creative thinking ability of high school students in relation to a  two-variable linear equation system. This study was conducted in a  high school in West Bandung district, and one class, namely class VIII B, with 23 students participated in the study. The method  used in this study is a descriptive qualitative method. This study used test instruments and non-test instruments in the form of questions and interviews. The effects confirmed that students have been able to resolve questions based on only  two indicators of creative thinking ability, ie. fluency 55.32% and flexibility 68%, and students could not  solve tasks based on news indicators one 14,44%. Based on the results of the interviews, this resulted in students who generally could not work  and solve questions with their own answers or thoughts, but only procedurally followed the SPLDV problem solving method.

Abstract

One of the goals of learning mathematics is that students can demonstrate an accurate conceptual understanding of problem solving. The research was conducted at one of the MTs in West Bandung Regency. The purpose of this study was to determine the MTs students' understanding of mathematical concepts in fractional material using a qualitative descriptive method. Data collection techniques are conducting written tests, interviews and documentation on class VII students. The written test uses questions that are in accordance with the understanding of mathematical concepts. The characteristics of students' ability to understand mathematical concepts were categorized into 3, namely students who answered correctly (SMT) as many as 5 people (33.3%) on the indicator Presenting models and non-model objects of a concept and expressing concepts in various forms of mathematical descriptions, students who answered incorrectly (SKT) as many as 7 people (46.7%) on the indicator restating objects against a concept and categorizing objects according to their nature according to the concept, and students who did not answer as many as 3 people (20%) on indicators applying a concept or algorithm in problem solving.

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

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.
