Abstract

This study aims to discover the mistakes made by students, especially class VII students at Koka Christian Middle School, when solving math problems on algebraic operations using the Newman procedure. This research is a type of descriptive research with a qualitative approach. The technique for collecting data used a written test by providing description questions that totaled 3 items and was supported by interviews with students and documentation. The subjects in this study were 16 students in class VII of Koka Christian Middle School who took the written test, and 3 of them were selected to be interviewed after a deliberation process. The results of the study showed that students made errors in solving math problems in the material for algebraic operations based on the Newman procedure, namely: 1). error in understanding the problem, where students need to write down what is known and asked by the problem or make examples in the form of variables. 2). problem transformation errors, where students cannot determine the mathematical model of the given problem or cannot determine the correct formula. 3). process skill errors, where students need clarification in the problem-solving steps due to errors in understanding the concept of algebraic operations. 4) final answer errors, where these errors result because students are wrong in the problem-solving process.

Abstract

The purpose of this research is to find out what types of errors students can make in solving mathematics Olympiad questions based on Newman's criteria and their causes. The method used by the author is a qualitative descriptive research method. The results of the research are: the errors made were the criteria for errors in understanding the questions (Comprehension Error), transformation errors (Transform Error), process skill errors (Process Skill) and errors in drawing conclusions (Encoding Error). The causes are: 1) lack of understanding or not understanding the meaning of the question. 2) not being careful in working on the questions. 3) don't understand how to process the information obtained from the questions. 4) students experience forgetting factors. 5) students cannot determine what formula to use in solving the problem. 6) don't know how to solve the existing problems. 7) less skilled in completing operations in mathematics. 8) rush. 9) students are lazy in solving existing problems and focus on solving other problems. 10) processing time has expired.

Abstract

This article aims to describe the application of Group Investigation type cooperative model to improve mathematics learning outcomes with statistics material in class VIII SMP NEGERI 2 MANADO. This type of research uses Quasi Experiment research. The population of this study was class VIII of SMP Negeri 2 Manado, 2 samples were selected, namely class VIII-1 as an experimental class with a total of 28 students and class VIII-3 as a control class with a total of 22 students. The research design used was Posttest-Only Control Design. The average value of the Posttest for the experimental class was 80.3571 and for the control class was 64.1363. Based on the results of research conducted in both classes using hypothesis testing, namely the t test with a significance level of 5%, it was found that then was rejected so that was accepted. Thus it can be concluded that student learning outcomes on Data Concentration Measures and Data Distribution Measures using the Group Investigation type cooperative learning model are better than using the direct learning model.

Abstract

This research was conducted to find out what factors hinder the learning of class VII students of SMP Negeri 2 Tatapaan for the 2023/2024 academic year on the material Systems of Linear Equations and Inequalities in One Variable. The population and sample of this research is 40. This research is a quantitative descriptive research that uses survey methods and data collection using research instruments in the form of questionnaires and interviews. The questionnaire created had 24 statement items. The results of the research show that the internal aspects of learning barriers in the One Variable System of Linear Equations and Inequalities material fall into the Moderately Obstructed category (65.74%), with the lowest indicator being student readiness which falls into the Quite Impeded category (48%). Furthermore, the external aspect of barriers to student learning in the material Systems of Linear Equations and Inequalities with One Variable was included in the Moderately Obstructed category (68.6%), with the lowest indicator being Family, which was included in the Moderately Obstructed category (55.5%).
