Abstract

This study aims to analyze students' mathematical problem solving abilities, especially in the material of the Three Variable Linear Equation System (SPLTV) using qualitative methods. The subjects of this study were class X students of TI Garuda Nusantara Cimahi Vocational School with a sample of 36 students with 18 male students and 18 female students. As for the data collection technique in this study, namely by testing the description test questions which amounted to 5 description questions tested on students based on indicators of mathematical problem solving ability; (1) Understanding the problem, (2) Planning to solve the problem, (3) Resolving the problem, and (4) Re-examining the process and results. Based on the results and discussion of the research, it can be said that the highest score indicator obtained by students is found in the first indicator, namely understanding the problem with a percentage of 61.11% and the one with the lowest score is the indicator of re-examining results with a percentage of 8.34% of the total percentage. . Meanwhile, when viewed from gender, female students have better problem-solving skills than males.

Abstract

The aim of the research is to develop learning media that are approprited and effective for use against mathematical understanding abilities in accordance with problem based learning steps and to find out the constraints encountered during the development process, this is done because of a lack of understanding of students in learning and a lack of use of learning media at school. The research method used was 4D R&D research and development which was modified to 3D (Define, Design, Develop) 44 (forty four) class VIII students as participants in the area test and product test, besides that supervisor I and II are also needed as validators. The results of this study are that the learning media developed are in accordance with the 3D R&D method, the learning media are appropriate and partical based on the validators and student responses which make learning media able to be implemented in class and the learning media used are effective and can be used students in 2 (two) class at one of the MTS in West Bandung Distric.

Abstract

The research was carried out with the aim of analyzing the mathematical communication skills of students on quadrilateral material in terms of self-directing learning. The method used is descriptive qualitative method. As many as 30 students of class VII A from SMP Pasundan 1 Cimahi were the subjects of this study. The data collection technique was in the form of a self-rating scale of self-directed learning (SRSSDL) questionnaire and a test instrument of 3 questions with indicators of written mathematical communication skills and interviews. The results showed that students with high self-directing learning had high mathematical communication skills by fulfilling all aspects of mathematical communication abilities. Students who are self-directing learning have average mathematical communication skills and are able to fulfill 2 aspects of mathematical communication skills, namely writing text and mathematical expression. Students whose self-directing learning is low have low mathematical communication skills which are only able to fulfill 1 aspect of mathematical communication ability, namely writing text and 1 indicator on the aspect of mathematical expression.

Abstract

The purpose of this study was to analyze the feasibility and practicality of scientific teaching materials assisted by scratch. This development research was conducted using the 4D method which was limited to the third step including the define, design, and development stages. At the feasibility and practicality test data analysis stage, data were collected through observation, questionnaires, and documentation. The feasibility of teaching materials is analyzed based on the results of expert validation and the practicality of teaching materials based on the results of student answers.  The results of this study indicate that the teaching materials tested are feasible and practical as learning materials for students. This is based on the results of validation by experts on the practicality of teaching materials filled in by students. The results of expert validation resulted in an average score of 91.83% with a very valid category, which can be said to be suitable for use in the field. The results of the practicality questionnaire analysis show that teaching materials are considered practical by students with a percentage of 85% on a small scale and 87% on a wide scale with a very practical category. This can show that the scientific teaching materials for quadrilateral and triangle materials assisted by scratch are very good for use during the math learning process.

Abstract

The aim of this paper is to find out empirically the relationship between readiness to learn mathematics and mathematics learning achievement in grade VII MTs Al-Masthuriyah Jakamulya, South Bekasi. This study uses a descriptive method with a survey technique in the form of a correlation study. The sample was taken from class VII-3 consisting of 34 students with purposive sampling technique. The research results obtained indicate that there is a positive relationship or correlation between learning readiness and mathematics learning achievement. This can be shown by the correlation coefficient rxy  = 0,863 and the regression equation  3,11+1,02x is obtained. The coefficient of determination shows that r2= (0,863)2=0,7448, which means that the contribution of the influence given to the learning readiness variable on the learning outcome variable in mathematics is 74.48%. The conclusion of this study is that there is a positive relationship between students' readiness to learn mathematics and learning outcomes in the chapter related to rectangular shapes for 7th grade students of MTs Al-Masthuriyah Bekasi Selatan.

Abstract

Peers have an influence on the development of adolescents, especially prospective students, especially when choosing a major in a college. Choosing a major in a college for each prospective student is often related to the peer group. Some prospective students in Indonesia when choosing a major are still influenced by peers when making a decision, this cannot be separated from the role of peers as people who have more or less in common in age and school who can broaden their views and influence the social development of adolescents, especially when a teenager will decide something regarding his education and career in the future. This study aims to describe the peer factor in influencing student interest in choosing a major in mathematics education. This research was conducted at IAIN Padangsidimpuan and the research participants were 25 students of the tadris/mathematics education study program at IAIN Padangsidimpuan. This research uses quantitative and qualitative approaches with descriptive research and percentage analysis techniques. In this study, the data obtained are data derived from questionnaires that have been filled out by research respondents. While the data analysis technique used in this study is statistical analysis of percentages, because the purpose of this study is to provide a description of the existing data. The results of peer factor analysis are divided into five categories in influencing student interest in choosing mathematics education majors, namely: a) very high influence 24%, b) high influence 40%, c) moderate influence 20%, d) low influence 12%, and e ) has a very low effect of 4%.
