Errors made by students in solving SPLDV problems based on Kastolan stage, identify the factors - causes, and analyze the scaffolding that can be used to handle it. The method used is qualitative descriptive with the sample of this study taken using a purposive sampling technique from the population of all students of class VIII Mts in one of West Bandung Kab in the academic year 2018/2019. Data collection techniques using documentation, text, and interview techniques. Data analysis techniques are carried out through the process of data reduction, data presentation, and conclusion drawing. Based on the results of data analysis, it was concluded that there were 9.4% of students who made conceptual errors, 27.2% were procedural errors, and 22.8% had experienced technical errors. The internal factor that caused the error was because students were not careful, lacked training in the problem, lacked understanding of the prerequisite material, lacked understanding of the concept of solving two linear variables, and lacked understanding of the basic concepts of elimination and substitution methods. Scaffolding that can be given is explaining, reviewing, restructuring, and developing conceptual thinking

In general, mathematics is a very boring and frightening lesson. So students feel unmotivated to lHHearn and a little curiosity, this causes low student learning outcomes in mathematical lessons. For this reason, improvement efforts are needed in the learning process by choosing the appropriate and appropriate learning model to use. The purpose of this study was to improve the mathematics learning outcomes of vocational students using the cooperative learning model type make a match. This research was conducted at TI Garuda Nusantara Vocational School Cimahi as the population, and the sample was X Multimedia 1 class, which amounted to 35 students. Data was collected using observation sheets for teacher activities, student activities, and written tests. Data analysis techniques used in descriptive way using data tables. From the results of the analysis carried out with the cooperative learning model type make a match proved to be able to improve student learning outcomes, especially in the field of Multimedia study in class X at TI Garuda Nusantara Cimahi Vocational School.

The purpose of this study was to explain the improvement in communication skills and mathematical connections of students after being given a contestant learning approach. The research was carried out experimentally at Budi Bakti Utama Middle School. The experimental class gets learning with a contextual approach while the control class gets conventional learning. The instrument consists of tests of learning devices to measure students' communication skills and mathematical connections. The test is done twice with the same questions, namely before and after learning (pretest-posttest). The research hypothesis was tested using the average difference test, namely the t-test. The results of the study showed: (1) Increased mathematical communication skills of the experimental class students more than the mathematical communication skills of the control class, and (2) Increasing the mathematical connection ability of the experimental class students more than the mathematical connection ability of the control class.

This study aims to improve students' mathematical reasoning abilities through learning with the Realistic Mathematics Education approach. This research is a Classroom Action Research (CAR). The subject of the recipient of the action was 27th grade students of Industrial Chemistry at Jabir Al-Hayyan Vocational School. Methods of collecting data through observation, field notes, tests and documentation. The results showed an increase in students' mathematical reasoning. This can be seen from the increasing indicators of mathematical reasoning abilities including; 1) the ability to present mathematical statements in writing as much as 28.57% increased to (90%); 2) the ability to draw conclusions in response to existing problems by 38.10% increased to 70%; and 3) the ability to analyze mathematical situations using patterns and relationships as much as 23.81% increased to 65%. It can be concluded that the application of the Realistic Mathematics Education (RME) approach can improve students' mathematical reasoning abilities

Publisher : Departement of Mathematics Education

This study will look at differences in the ability of mathematical connections and self-regulated learning of junior high school students who obtain mathematics learning using the Contextual Teaching and Learning approach through the Cooperative Type Think Pair Share model, one of the causes of the low mathematical connection ability of students lies in the approach factor and the learning model when teaching. Based on the description of these problems, improvements can be made to improve students' mathematical connections with the Think Pair Share Cooperative Model. the population and sample in the study focused on eighth grade students, the method used in this study was a quasi-experimental method. Data collection techniques are by giving intrusion of learning and working on problems, then grouping grades based on the results of student performance in working on mathematical problems, arranged based on group distribution data to more specific value distribution into the mean median mode and graphs in order to know the results of applying the Type Cooperative model Think Pair Share is expected to improve students' mathematical connections.

The purpose of this research is to find out students' mistakes in solving algebraic operations according to Kastolan's theory. In this study used a qualitative descriptive method with the research subject of class VII in one of the MTs in West Bandung Regency with a total of 20 students consisting of 9 girls and 11 boys. The data collection technique was carried out in the form of a written test consisting of 5 description questionsFrom the results of the analysis of student errors based on Kastolan theory, there are several types of Kastolan errors overall, namely: 1) the type of conceptual error is 60%, this type of error is included in the high category 2) the type of procedural error is 40%sufficient category and 3) the type of technical error by 30% this type of error is included in the low category. Based on the results of the analysis that has been obtained from students' answers, the cause of the errors that exist in each of these errors is an error in making mathematical models, students do not show completion strategies and students' lack of ability to perform arithmetic operations.

Learning difficulties are external factors that have an impact on the low learning outcomes of students in mathematics. Another element that adds to learning difficulties is the lack of enthusiasm (motivation) for learning and makes students reluctant and lazy to learn mathematics. The reasons for carrying out the analysis of this study include finding, identifying and assessing learning difficulties faced by class VII students at SMP Negeri 1 Cililin, as well as students' mistakes when working on set material questions. The method used in this research is by using descriptive qualitative method. Participants in this study were 18 students. The approach of collecting data in this research is by giving a test test of three questions in the form of a description. Based on the money study that has been carried out, there are several aspects of learning difficulties including although most students already understand the concept of the set, they still experience some learning difficulties, such as not being able to understand the problem, not being careful in recording the members of the set, and having difficulty in making the required mathematical model.
