Abstract

Ethnomathematics is a realistic approach to learning mathematics that relates mathematical concepts to culture. By learning mathematics relevant to the student environment's culture, students will more easily understand mathematical concepts. This study aimed to examine theethnomathematical exploration of the Kebyok Anting-Anting dance floor pattern for learning the concept of geometry. This research is qualitative research using the ethnographic method. The instruments used are interviews, observation, and documentation. Data obtained through interviews and observations were analyzed using the analytical method described by Miles & Huberman, there are data reduction, data data display, and conclusion drawing/verification. The results showed that the ethnomathematical investigation in the Kebyok Anting-Anting dance floor patterns for learning the concept of geometry were horizontal lines, vertical lines, squares, rectangles, isosceles trapezoids, isosceles triangles, and parallelograms. It is hoped that various local cultures can be used to introduce other mathematical concepts.

Abstract

The role of prior mathematical knowledge and interest in mathematics as internal factors that can influence the mathematical concept understanding ability in learning mathematics in schools is important to consider. The purpose of this study was to determine the effect of prior mathematical knowledge and interest in mathematics to mathematical concept understanding ability. This study uses a quantitative research approach with data analysis techniques using multiple linear regression analysis. The participants in this study totaled 91 students who were all students of class X MA As-syafiiyah 02 Kota Bekasi for academic year 2022/2023. The results of this study were obtained: 1) Students' prior mathematical knowledge had a significant effect on students' mathematical concept understanding partially 2) Students' interest in learning mathematics had a significant effect on student’s mathematical concept understanding partially 3) prior mathematical knowledge and interest in learning mathematics simultaneously had a significant influence to the mathematical concept understanding ability. This can be interpreted that the acquisition of students' mathematical concept understanding ability can be increased by considering the factors of prior mathematical knowledge and students' interest in learning mathematics.

Abstract

Set is one of the main materials contained in the mathematics subject for 7th-grade junior high school in odd semesters. In the set material, there's no formula used, but there are various kinds of notations, symbols, and also diagrams. Basically, some or even most students still face various difficulties in understanding and working on problems in set operations. This study aims to determine the types of errors and the percentage of errors in 7th-grade junior high school's responses to set material test questions using Newman's error analysis procedure. In this study, we used a qualitative descriptive method, while the data processing technique was done by analyzing student answers based on questions that were test instruments. The research subjects were taken from students in the VII-E class at SMP IT Fithrah Insani, which included as many as 22 students. Then the subjects were analyzed, and based on the results of the research, it turned out that there were still errors in solving set questions. The most frequent error made by students is an encoding error of 40.91%. In this error, the student did not write a complete final answer, or even the conclusion of the solution, so that he did not answer the question posed by the problem.

Abstract

This paper reports an investigation of students' understanding of the concept of factorization in algebraic forms learned in secondary school. A total of 31 grade 8th junior high school students were selected by purposive sampling technique as respondents in this case study research. The case study approach is considered in accordance with the objectives of this study, namely obtaining in-depth knowledge of student problems, knowing the causes of these problems, and efforts that can be made to help overcome them. Methods of collecting data using written tests, interviews, and documentation. Data analysis techniques include data reduction, data presentation, and drawing conclusions. The results showed that there was a misunderstanding of students' concepts about the concept of factorization in algebraic forms so that they experienced difficulties in "algebraic manipulation". One of the causes of these difficulties is the lack of students' understanding of the equals sign as a sign of equality. The principle of mathematical equivalence serves as the main link between arithmetic and algebra. The operation transformation and the meaning of the equals sign in arithmetic as equality can underlie "algebraic manipulation".

Abstract

To study at school, students must have soft skills such as self-regulated learning, namely the ability of students to manage their own learning. The significance of students' self-regulated learning is what inspired this study. This study sought to ascertain the rise in students' self-regulated learning when learning mathematics using a realistic mathematics education model, as well as the students' reactions to learning mathematics using a realistic mathematics education model. This kind of study uses questionnaire analysis to do descriptive research. A self- regulated learning questionnaire and a questionnaire for students' responses made up the tool used to assess the self-regulated learning abilities that had been put to the test. Data were collected for this study to examine the rise in realistic mathematics education students' ability to learn mathematics independently, as well as the students' attitudes toward learning mathematics through mathematics education, which were assessed using a Likert attitude scale. The self-regulated learning scale is made up of four parts: the students' evaluations of how well they (1) use and locate pertinent learning resources in mathematics, (2) select and determine their learning strategies in mathematics, (3) assess and evaluate their learning outcomes in mathematics, and (4) have a positive view of themselves as mathematicians. By utilizing realistic mathematics education, the findings of this study about self-regulated learning in mathematics can be viewed as a whole. Based on the results of data analysis it is known that students' responses to realistic mathematics education models are positive which are adapted to real-life contexts or everyday life which will arouse students' self-regulated learning in solving problems because they are related to real life. This demonstrates that 98.18% of students respond positively.
