This study aimed to knowing and describe students' mathematical representation skills in solving relational and function problems for class VIII in academic year 2021/2022. The research method used was descriptive research with a qualitative approach. The instruments used were mathematical representation ability tests and interview. The research subjects were students VIII C with 30 students who were given a mathematical representation ability test grouped into high, medium, and low categories based on their mathematical ability. From each category, 2 students were selected to be interviewed further. In general, from the test results, students with high mathematical representation abilities have been able to achieve indicators of mathematical representation abilities with an achievement percentage of 82.63% which is very good. Students with moderate mathematical representation skills with an achievement percentage of 51.26%, which is sufficient. and students with low mathematical representation skills with an achievement percentage of 25.95%, which is less. From the results of interviews, students with high mathematical mathematical representation abilities were able to explain the answers to the test results very well. Students with moderate mathematical representation skills are quite able to explain their answers well. Students with low mathematical representation ability are able to explain the answer but the explanation given is less detailed.

Abstract

This study aims to determine the effect of problem-based learning models on students' Pythagorean theorem problem solving ability. This research was carried out at SMPN 1 Suralaga for the 2023/2024 school year. The type of research used is a quasi experiment. The population in this study were class VIII students of SMPN 1 Suralaga for the 2023/2024 academic year. The sample was 44 students consisting of 22 experimental class students and 22 control class students. The data collection techniques used are observation and tests. While the research instrument consists of observation sheets, problem-solving ability test sheets, lesson implementation plans and student worksheet. Data taken with t-test, obtained acceptable results    accepted, there is a difference in the problem-solving ability of the Pythagorean theorem in students whose learning used the problem-based learning model with students who used the direct learning model. The average posttest result for the experimental class was higher than the control class, namely 82.41>75,00.  This shows that there is an influence of the problem based learning model on the Pythagorean theorem problem solving abilities of class VIII students at SMPN 1 Suralaga using the effect size test, obtained d=0.67, which means the influence given is in the medium category.

Abstract

This study aims to determain to increase the student’s ability to think more critize in number pattern material matery class VIII MTsN 1 Lombok Barat 2023/2024 with PBL model with interactive lesson media. The methode that used in this research is experimental methode. This research have been taken in two classes, the first one is experimental class and the other one is control class. The experiment class is used PBL model with interactive lesson media. Meanwhile, the control class is used PBL model. The instrument that used in this research is interactive PPT and the instrument that used in collecting data is the ability test of critical thinking. The average score of theexperimental class was 72.03 and the average score of the controlclass was 59.72. This means that learning using the PBL model assisted by interactive learning media is more effective than learning using the PBL model. The initial average score ofexperimental class students was 67.55 after applying the PBLmodel assisted by interactive learning media obtained an averagescore of 72.03. This shows that there is an increase of thestudent’s in critical thinking skills of number pattern material ofgrade VIII MTsN 1 Lombok Barat 2023/2024 after applying thePBL model assisted by interactive learning media.

Abstract

The purpose of this study was to describe students' problem solving abilities in social arithmetic material in terms of learning style. It was a qualitative descriptive study. The instruments for this research are questionnaires, tests and interviews. Of the 151 students given a learning style questionnaire, there were 100 students with a visual learning style, 30 auditory students, and 21 kinesthetic students. A total of 32 students were given a test, then 9 subjects were selected to be interviewed consisting of 3 students from each learning style and selected through purposive sampling to deepen the data. Qualitative data analysis uses 3 stages, namely reduction, presentation and drawing conclusions. The research results show that students with a visual learning style are able to reach the stage of understanding problems, making plans, solving problems and checking again. Visual students fall into the category of high problem solving abilities. Auditory students are able to reach the stage of understanding problems, making plans, solving problems. Auditory students fall into the category of moderate problem solving abilities. Kinesthetic students are able to reach the stage of understanding problems and making plans. Kinesthetic students fall into the category of low problem solving abilities.
