Abstract

The ability to understand mathematical concepts is important in learning mathematics. Students are often having difficulty in understanding mathematical concepts when the learning process takes place. The purpose of this study was to describe students’ ability to understand mathematical concepts on linear equation system of two variables without given any prior treatment. The linear equation system of two variables materials test was conducted in class VIII.1 of SMPN 7 Tanjungpinang on Thursday, 29 April 2021, to 34 students. The instrument used is a test instrument for the understanding ability of mathematical concepts. Based on the data analysis that has been done, the percentage ability to understand mathematical concepts in question number 1 with the indicator of restating a concept, is 79% with high criteria. In question number 2, the indicator that identifies examples and not examples of a concept shows as much as 89%, which is a very high criteria. In question number 3, the indicator presents the concept in the form of a mathematical representation, which is 68% with high criteria. In question number 4, the indicator applies the concept in an algorithmic manner, which is 86% with very high criteria. In question number 5 with indicators of applying algorithms concept in problem solving as much as 60%, is high criteria. According to these data, it can be concluded that the students' ability to understand mathematical concepts in solving systems of linear equations in two variables questions is categorized as high with the percentage of 76,4%.

Abstract

This research is motivated by problems, the low level of students' self-efficacy abilities. One alternative learning that can be applied to improve students' self-efficacy abilities is a realistic mathematical education. The purpose of this study was to determine the increase in students self-efficacy abilities with a realistic mathematical education in mathematics learning, and to determine students' responses to mathematics learning by using a realistic mathematics education. The design used in this study was a pretest-posttest control group research design, with a quasi-experimental method. The population in this study were all class VII students of Al-Ulum Private Junior High School Medan, while the sample in this study were students of class VII 3 as the experimental class and class VII 5 as the control class who were randomly selected class. The instrument used is a self-efficacy questionnaire to see the ability of self-efficacy that has been tested and a questionnaire to see student responses. In this study, data was obtained to see the increase in students 'self-efficacy abilities with a realistic mathematics education in mathematics learning and to see students' responses to mathematics learning using a mathematical education which was analyzed using a Likert attitude scale. Based on the analysis of the results of the self-efficacy questionnaire obtained from the improvement of students' self-efficacy abilities with a realistic mathematics education.

Abstract

Based on the results of PISA and TIMSS, the mathematical ability of Indonesian students is at the cognitive knowing level which is the lowest level. This study aims to analyze: (1) students' mathematical representative ability through, and (2) the difficulty of representative experienced by students in solving problems of representative ability. The method of this study is qualitative research. The results showed: (1) students with high representative ability in terms of male and female genders were able to present pictures to solve problems. Students with the ability to represent are being viewed from male students who have not been able to aspects of words or written texts. Whereas female students are not yet capable of aspects of visual representative and the written words. Students with low representative ability in terms of male gender have not been able to visual present images. Then, aspects of mathematical expressions and written words have not been able to make mathematical model and written words. (2) the difficulties experienced by male students in solving problems of representative ability experiencing difficulties in terms of principles, verbal aspects and procedural terms. While the female students experiences difficulties in terms of concepts, aspects of principles, aspects of verbal and procedural terms. The conclusion in this study: female students in the high ability category more than male students. In the medium ability category, male students more than female students. In the low ability category, female students more than male students.

Abstract

This study aims to describe students' mathematical problem-solving abilities based on the category level through the Polya steps. the stages of solving the problem pattern consist of the stage of understanding the problem, planning solutions, and checking again. The subject of this study chose six people from thirty-one students from class VIII SMP Negeri 1 Soe. Data collection by conducting tests and interviews. the results showed that the upper category students did not experience difficulties at the stage of understanding the problem and making plans, while at the stage of implementing the plan there were still parts that were not done because they felt that they were not needed, while at the stage of re-examining students in the upper category they did not do it. students in the medium category can already understand the plan well, while at the planning stage it has not been fully carried out, so at the stage of implementing the plan not all of them can do well either, for the medium category no one checks again. students with low categories have not been able to fully understand the problem and make plans, so they cannot carry out the plan and also cannot check back on what has been done. Subjects with high score categories have been able to solve problems even though they are still not perfect, subjects with moderate value categories have sufficient problem-solving abilities, and subjects with low-value categories have very poor problem-solving abilities.

Abstract

The purpose of this research is to see how effective the learning media that have been designed are. The method used in this research stage is development research, in which learning media based on the Comic Life assisted set materials are developed.  This Study included 54 students from Bandung and 114 students from Ngamprah Subdistrict from the Junior High School association VII grade level. In the development of media, there are four stages of research namely define; design; develop; disseminate. The stage result in an average data validation of the material expert of 76.3% for the first stage and 80.8%% for the second stage. Stage I validation findings were 53.3%, stage II validation was 74%, and stage III validation was 81%. Student replies of 76% and instructor responses of 78% revealed the findings of the validation in limited trials and broad trials. Meanwhile, 79.5% of student responded positively during product testing. The level of efficacy of learning media utilizing Comic Life is attained with an N-Gain of 0.34, implying that the level of effectiveness of Comic Life assisted learning is quite effective. According to the findings of the mathematical communication and disposition exam, students who study using the Problem Based Learning approach with Comic Life have a better-mathematical abilities than those who learn conventional learning. In terms of mathematical disposition, it can be determined that students who utilize the Comic Life assisted Problem Based Learning technique have a better mathematical disposition than those use conventional learning. This development research is based on the learning design produced and the characteristics of students.
