Abstract

This exploration begins from the low math learning results of class VIII G understudies at SMP Negeri 1 Nubatukan. This is tracked down in the aftereffects of re-obtainment in class. Taking into account the consequences of the exploration on the Cartesian directions material, it was acquired information that there were still understudies who had not finished as per the Base Fulfillment Rules (KKM), which was 60. Of the 27 understudies, just 14 understudies or 51.85% passed. The inspiration driving this exploration is to settle on the utilization of KoCar media in the further advancement of understudy learning results on the Cartesian Directions material. The sort of exploration applied is Study hall Activity Exploration (Vehicle) which is brought out through 2 (two) cycles with each cycle comprising of 4 (four) stages, specifically the preparation, execution, perception, and assessment stages. The outcomes showed an expansion in understudies' arithmetic learning results in the wake of learning with KoCar media was applied, which was set apart by an expansion in scores from 53.22 to 82.41 in cycle II. Furthermore, understudies' activities have created during the educating and educational experience in the study hall. In light of the consequences of the execution of this learning, one might say that the utilization of KoCar media can additionally further develop the learning results of class VIII G understudies on the Cartesian Directions material.

Abstract

This study aims to explain students pseudo-thinking errors on mathematical problem-solving skills  that are reviewed supported on high, medium, and low self-confidence. This research was conducted at SMAN 60 Jakarta class XI MIPA II for the 2020/2021 academic year. The subjects taken were 3 out of 38 students. This research method is a descriptive qualitative approach. Researchers used self-confidence questionnaires, problem-solving ability tests, and interviews. The material being tested is the derivative of algebraic functions. The results obtained stated that students with high self-confidence scored perfect test scores but there were a few writing errors. The completion step, therefore, included pseudo-correct thinking. Students with moderate self-confidence can do the questions well, but there are inaccuracies so that the results are wrong. Therefore, students with moderate self-confidence enter the indicator of pseudo-wrong thinking errors with information that can reflect on their answers. In students with low self-confidence, they face errors in compiling the completion steps but can rectify and find the correct answer. With this, students with low self-confidence fall into the indicator of pseudo-correct thinking errors with information on understanding the wrong concept.

Abstract

This research aims to describe the critical thinking ability of mathematics students of class VIII of Junior High School N 2 Magelang. The subjects in the study were students of grades VIII-A and VIII-D. The research was carried out in the even semester of the 2021/2022 school year. The data collected is in the form of learning style questionnaire results, mathematical critical thinking ability tests, and interviews in an unscathodox manner. Learning style questionnaires are used to determine students' learning styles, tests to measure mathematical critical thinking ability consist of four questions about the description of polyhedron materials. The results of the questionnaire and test were then analyzed according to the indicators of mathematical critical thinking ability used in this study, namely providing basic clarification, bases for a decision, inference, advanced clarification, supposition and integration. The results of data analysis show that students' critical thinking ability in visual, auditorial, and kinesthetic learning styles is classified as moderate. The results of this study can provide information to teachers about students' critical thinking ability so that teachers are expected to be able to design learning activities that can improve students' critical thinking skills to be good.

Abstract

Most junior high school students have difficulty in solving math problems, causing students to make mistakes in solving math problems. The purpose of this study is to analyze the types of mistakes made by students in doing problems in the pythagorean theorem material. This type of research is qualitative descriptive research. The instruments in this study are test and interview instruments. The subjects of the study were as many as 9 students from class VIII at SMP Negeri 25 Kota Serang. The results of error analysis in this study show that students made mistakes in solving mathematical problems in the pythagorean theorem material in the form of fact errors, concept errors, principle errors and operating errors. The percentage of errors made by learners on factual errors was 17%, the percentage on conceptual errors was 44%, the percentage on principle errors was 17%, and the percentage on operating errors was 22%. The type of mistake most made by learners is the type of misconception. Concept errors occur because students do not understand the concept of pythagorean theorem material, causing students to have difficulty in solving mathematical problems in pythagorean theorem material.

Abstract

This study aims to analyze the effectiveness of the problem-based learning model assisted by Student Worksheets (LKS) to improve students' mathematical connection skills on the flat side of cubes and block material. The research design of this present study is a quasi-experimental design with the research population from class VIII students of SMP Negeri 1 Bandongan. The samples in this study were students of class VIII B as the experimental class and VIII C as the control class. The tests used in this study were the One sample t-test and the N-Gain test to see the extent of the increase in the pre-test and post-test scores. The results of the One sample t-test showed that the average of the experimental class > minimum completeness criteria, while in the control class < minimum completeness criteria. The N-Gain test revealed that the average N-Gain value of the experimental class was higher than that of the control class. The results showed that the problem-based learning model assisted by Student Worksheets (LKS) was effective in improving students' mathematical connection skills in the material for building flat sides of cubes and blocks at SMP Negeri 1 Bandongan.
