Abstract

This study aims to determine whether the mathematical problem solving ability of junior high school students who use a contextual approach with the cooperative model of think pair share type is better than the scientific approach. The subject of the study was the eighth grade junior high school students in Cimahi, while the sample was class VIII B as an experimental class that got learning using a contextual approach with a cooperative model of think pair share type and class VIII C became a control class that got learning using a scientific approach. The instrument in the study was a matter of mathematical problem solving ability consisting of five item description items. Based on the results of all stages of the study, it can be concluded that the mathematical problem solving ability of students whose learning uses a contextual approach through a cooperative model of think pair share type is better than that of learning using a scientific approach.

Abstract

This study aims to be able to analyze the difficulties of Grade VIII students of SMP Negeri in solving statistical questions. The method used is the case study method. The data used are written tests and interviews. The population and sample in this study were 32 students. The instrument of this study used a questionnaire, namely 6 questions related to statistical questions. Data processing is used by means of written tests and pictures of student answers. The research procedure is the stages of planning, operating, data analysis, and concluding a data. The research will be tested with a number of statistical questions at the application and testing stages, then interviews will be given to several students. The results of the analysis show several criteria based on students' ability to solve statistical problems. Students with high abilities have difficulty in determining the final answer. Students with moderate ability levels experience difficulties in calculating an answer. Students with low ability levels have difficulty understanding the questions given and lack understanding of the material.

Abstract

This research focuses on the results of the analysis of the errors that occur when students solve problems related to matrices at the high school level, assuming that there are many errors in solving these problems from different perspectives. The main purpose of this research is to find out the most common types of errors and the factors affecting them, based on the research object presented by the researcher. The study was prepared through a qualitative study, where the results of an error analysis obtained directly from the evaluation of high school students were examined. From the results of the study, it can be concluded that students' errors in solving  matrix material problems include different types of errors, which  are usually identified as errors in performing matrix operations, such as  addition or subtraction errors of matrix elements. In addition, there are  errors in understanding the basic concepts of matrices, such as errors in identifying the size of a matrix  or identifying the elements of a matrix. Contributing factors to these errors are lack of conceptual understanding, lack of practice and confusion in applying the relevant formulas.

Abstract

This study is a descriptive qualitative research for the purpose of analyzing errors and explaining the types of mistakes made by students when solving problems based on the text format provided. This research was conducted at a tertiary institution in Cianjur, with 10 research subjects in class VII B in the odd semester of the 2022/2023 academic year at SMP Negeri 5 Pasirkuda. The data collection method in this study was in the form of a written test. Based on the data presentation, the student error rate is 1) conceptual error, namely 66.9% with a "high" error percentage; 2) 10% procedural errors with a percentage of "very low" error categories; 3) 22.1% technical failure with a "low" failure percentage rate. Therefore, we can conclude that the conceptual understanding of student set material is relatively low. Therefore, the teacher should pay attention to students' conceptual understanding of the overall concept of the material and show students the important parts of the whole concept.

Abstract

This research aims to develop an analytical geometry ethno-project module. This research was conducted at IKIP Siliwangi, with 50 students as research subjects. This research uses Research and Development (R & D) ADDIE module. This research concludes. Based on the results of the development research that has been carried out, it can be concluded that the development of the analytical geometry ethno-project module has obtained very valid, practical and very effective qualities, so that the learning module is suitable for use in further analytical geometry learning. Apart from that, from the results of the development of this learning module, students can increase their creativity in the form of skills in making analytical geometric batik designs in the form of drawings in analytical geometry including: triangles, quadrilaterals, circles, parabolas, ellipses and hyperbolas.

Abstract

The aim of the research is to find out whether there is an increase in students' mathematical reasoning abilities with the discovery learning learning model compared to ordinary learning. The method used was quasi-experimental with a non-equivalent pretest-posttest design. The population in this study were class VIII students at SMP PGRI 1 Cimahi. The sample in this study was 30 students from class VIII-C and class VIII-D for each class. Class VIII-C is used as an experimental class and class VIII-D is used as a control class. The data collection technique in this research was through a written test consisting of six descriptive questions. The data obtained will be analyzed and processed with the help of IBM SPSS version 26 for Windows software. Based on the research results, H_0 was rejected and H_1 was accepted, meaning that there was an increase in the mathematical reasoning abilities of students whose learning used regular learning. Thus it can be concluded that there is an increase in mathematical reasoning abilities in the experimental class which uses the Discovery Learning Learning Model.
