Abstract

This study aims to analyze students' errors in solving questions on relations and function material, based on the Kastolan stages. In this study, a qualitative descriptive method was used. This research was conducted on Class VIII students of SMPN 4 Cimahi with 29 participants. Data was collected through a written test consisting of 5 description questions, and any mistakes made by students were explained based on the Kastolan stages. To analyze the data, the researcher performed data reduction, data presentation and conclusion. The research results obtained that in the work of students found conceptual errors occurred because the students misunderstood the concept and did not know the formula to be used. Procedural errors occur because students do not write down or do not know the completion procedure, which indicates the student fails to continue the settlement procedure. Technical errors occur because participants do not understand the basic concepts properly, so students make calculation errors when solving problems. The conclusion from the results of this study is that it was found that students still experienced these three types of errors in solving the description questions on the material relations and functions.

Abstract

Problem solving abilities play an important role in solving mathematical problems. Problem solving indicators consist of 4 (four), namely: (1) understanding the problem (2) preparing a settlement plan (3) carrying out problem solving (4) re-examining the results of the work. The purpose of this study was to analyze the mathematical problem solving abilities of students on junior high school social arithmetic material. The method used in this research is descriptive qualitative. The research subjects were class VIII students of SMPN 4 Cibinong, totaling 10 people and the research was conducted at SMPN 4 Cibinong. The instrument used in this study was a test about the description of mathematical problem solving abilities of 5 questions. The results of this study are the level of students' problem solving abilities on troubleshooting step 2, 3, and 4 with social arithmetic material which is still relatively low. This data is obtained from the results of the problem-solving ability test according to the indicators.

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 study aims to find out how effective the use of contextual approaches is to improve students' critical thinking abilities in the transition period as the study intends to detail and conclude the technology that is currently being used as well as the benefits and limitations it has. The SLR stage is grouping data, analyzing and summarizing the data that has been obtained. To develop students’ critical thinking skills, contextual learning is applied that emphasizes the ability to think at a higher level, linking it to everyday life so that students can transfer that knowledge through scientific disciplines, then collect, analyze, and conclude data obtained from some different information and points of view. The research results obtained are as follows: (1) The use of contextual approaches to learning is very effective in improving students’ critical abilities, (2) characteristics of contextual approaches are very effectively used to improve students’ critical thinking abilities, (3) students are not only fixated on one source but many sources can be obtained by students, thus training students’ critical thinking skills.

Abstract

This research was motivated by junior high school students lack of interest in learning mathematics subjetcs, so their mathematical understanding abilities tend to be low. The aim of this research was to find out how much influence the use of statistical material learning media using a Scratch-assisted scientific approach has on the mathematical understanding abilities of junior high school students. The subjects in this research were 26 class VIII students at SMP Negeri 15 Cimahi who were selected using a purposive sampling technique. In this research, the method used was an experimental method with a one group pretest-posttest design. Meanwhile, the data analysis technique used is quantitative descriptive which is then processed using Microsoft Excel 2013. After the test was carried out, there was an increase in the students average score. Before reciving treatment, the average learning outcome was 46,15, after reciving treatment, the average increased to 86,15. Apart from that, the number of students whose scores reached the KKM also increased. This proves that the use of Scratch-assisted learning media in statistics material has a great influence on junior high school students mathematical understanding abilities.
