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%.

Abstract

This study aims to determine the student difficulties in the SPLDV material. This research is a quantitative descriptive study that examines students difficulties yn the SPLDV material based on indicators (1) Modeling the SPLDV (2) Analyzing the completion of the SPLDV (3) Finding the solution to the SPLDV using Elimination and Subtitution methods (4) Summarizing the grap and (5) Linking the SPLDV in everyday life. The research was carried out in one of the private junior high school in Padalarang. The subjects of this research ere 15 students who have studied the SPLDV material. The data collection is by giving questions to student. The data analysis technique went though three stages, namely data reduction, data presentation, and conclusion. The results of the study show that there are still students who have difficulty in concluding the indicators of the graph, this can be seen from the average value of 27% which belong to the very poor category. It is also found that the factors that make the indicators on the SPLDV material esperience difficulties are the lack of accuracy when working on problems, difficulty in classifying known objects, and not mastering the concepts and principles of SPLDV.

Abstract

This research was conducted with the aim of finding out the errors in the creative thinking ability of MTs students in solving Social Arithmetic problems due to the low level of mathematical creative thinking. This research was conducted by one class VII MTs students in one of the MTs in West Bandung Regency who had implemented the 2013 curriculum. The analytical creative thinking ability has indicators that include fluency, flexibility, originality and elaboration. The data collection technique used is in the form of a 4-question test result in the form of a description of the social arithmetic material, then a description of the errors in each question number. The data analysis carried out is data reduction, data presentation and conclusion drawing. The conclusion obtained from the results of this study is that the creative thinking ability of MTs class VII students in one of the MTs in West Bandung Regency has a fairly creative category and students' mistakes in solving social arithmetic problems are the lack of finding new ideas and using various methods or completion steps and mistakes. in understanding the problem due to a lack of deeper understanding of the material.

Abstract

The purpose of this study was will explain students' mistake when working on math problem on the lesson of flat-sided geometry material at SMP Negeri 8 Cimahi Class VIII, namely 27 people. Used qualitative research with descriptive method. How to collect data, namely test instruments and interview with seven description question. The results of the student's response test for question number five were 29.63%, for question number seven it was 37.04%, and for question number three it was 40.74% still very low. Research conducted by students is difficult when working on these question. Explanation of data and assessment of students made part type of errors, is: (1) students' difficulties in understanding concept; (2) difficulty understanding question or not being careful when understanding question so that students' response are incomplete; (3) difficulty in understanding mathematics theory or the prerequisites of the Pythagorean theorem; (4) lack of accuracy when working on the calculation phase. This proves that class VIII students are very low when working on the problem of building a flat side room.

Abstract

This research is a type of qualitative research that aims to describe online learning of one variable linear equation (PLSV) material for seventh grade students at MTs Ibnu Sina. The research subjects were 7 people, the selection of students was random. Data were obtained through student response questionnaires, interview guidelines and test questions.  Then the data obtained is analyzed and then presented in the form of a percentage according to the indicator. The results showed that students prefer face-to-face learning for mathematics. From the results of the study it was found that 85.7% of students prefer offline learning, one of the reasons is seen from the interaction factor, in online learning the interaction between students and teachers is limited. The student test results showed that there were 4 types of student errors in answering the questions, 1) understanding the questions, 2) compiling mathematical models, 3) completing mathematical models, and 4) interpreting the questions. The highest percentage is making a mathematical model as much as 57.1% of the 7 students who took the test.
