Abstract

The research was carried out with the aim of analyzing problem-solving abilities in junior high school students related to number pattern material in terms of gender. The method used is descriptive qualitative. The subject of the study was a class VIII student at one of the junior high schools in Karawang Regency in the odd semester of the 2022/2023 academic year. The procedure for data collection uses a test instrument that combines four indicators in the form of, understanding, planning, implementing planning, and reviewing processes and results in problem solving. The data analysis technique is to look at the test results of students and then categorize them on high, medium, and low criteria. The results showed that the mathematical problem-solving ability of female students was better with an average score of 80.76 in the high category than male students with an average score of 69.58 in the medium category. This can result in differences in students' ways of thinking, understanding, and solving problems.

Abstract

Goal of this study was to examine the mistakes made by SMP Plus Al-Irfan students as they attempted to solve a system of two linear equations using online instruction. Research is being conducted using the descriptive qualitative technique. The research involved a total of 28 SMP Plus Al-Irfan class VIII students. The test instrument consists of six description-style questions. The indicators are: (1) Determining the distinction between PLDV and SPLDV; (2) Create a mathematical model and solving SPLDV use elimination methode; (3) Create a mathematical model, and solving SPLDV and use the substitution method; (4) Create a mathematical model, and solving SPLDV use the combined method; (5) Identifying special SPLDV and its solutions; and (6) Create a mathematical mode and solving SPLDV use the graphical method. According to the study's findings, junior high school students made the most mistakes in identifying the SPLDV graphical method's completion indication, with an error rate of 85.5%. According to the primary factor analysis's findings, students make mistakes, particularly when trying to convert story questions into mathematical models and create SPLDV graphs.

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

This study aims to determine the improvement of students' mathematics learning outcomes by applying a problem based learning approach to algebraic form of material. The method used in this research is classroom action research (CAR) which was carried out in one of the junior high schools in the Cimahi area. This research was carried out for two cycles, with the techniques used were observation, test questions, and also documentation. The subjects of this class action research were teachers and students of SMP class VII which consisted of 22 people. The increase in student learning outcomes is reviewed based on the results of working on individual test questions. The questions are given before and after the algebraic form material is delivered. Based on the results of the study, it was shown that learning mathematics by applying a problem based learning approach to algebraic form material could improve student learning outcomes.

Abstract

Covid-19 is a rapidly growing outbreak around the world, one of the obvious impacts is the education sector. Inadequate education affects the learning outcomes of learners. One of the factors that affect student learning outcomes is the presence of motivation that comes from the student itself. Without the willingness to learn, it can be difficult for students to know what to learn and why they need to learn it. The research used is correlational and ex-post facto research using quantitative approaches that aim to find out whether students' learning outcomes in statistical material have an effect on learning motivation. The subjects used in the study were class IX students consisting of 6 students including 3 women and 3 men. Research instruments conducted using student motivation scale questionnaires and written tests of statistical material. The data analysis technique used in this study is a simple linear regression analysis using an average percentage of motivational indicators and spsss statistic 25 software. The results of the study proved that there was an influence of 62.2% between learning motivation and student learning outcomes.
