However, the reality in the field in junior high school students, students have difficulty in learning transformation geometry, namely in the material of reflection, rotation, translation and dilatation. This difficulty of students is caused by students not understanding the coordinate points on the cartesian plane. The difficulty of students in determining cartesian coordinates has the effect that students cannot determine straight-line drawings based on straight-line equations. Another thing that causes students difficulty in understanding the geometry of transformation is that students' ability to think abstractly is still very low, students cannot describe concepts from mirroring, turnover, shifting and dilatation. The purpose of this study is to understand the geometry of trasnsformas through the exploration of Jambi batik. The research method used is descriptive qualitative, the result of the research obtained is that there is a concept of transformation geometry in Batik Motik Jambi so that it can be applied in mathematics learning2023-01-18T18:02:31+07:00Copyright (c) 2023 Prima: Jurnal Pendidikan Matematikahttps://jurnal.umt.ac.id/index.php/prima/article/view/7312ETHNOMATHEMATICS VALUES IN SUMEDANG TOFU AND BONGSANG (TOFU BASKET) FOR TEACHING GEOMETRY IN PRIMARY SCHOOL2023-01-18T18:02:31+07:00Riana Irawatirianairawati@upi.eduRahman Rahmanrahmanprofupi@upi.eduRetno Andriyaniretnoandriyani@upi.eduEjen Jenal Mutaqinjenal86mutaqin@upi.eduNurdin Kamilnurdinkamil11@upi.edu<p>Ethnomathematics can be an option for teaching a more contextual mathematics which contributes to a successful mathematics learning. The present study highlighted ethnomathematics concepts that could be found in Sumedang’s local food, namely Sumedang Tofu, and the bamboo basket used as its container (<em>bongsang</em>). Mathematical concepts in Sumedang Tofu and its <em>bongsang</em> are related to geometry. Geometry allows students to develop their abilities in presenting or describing the order in the world or their immediate environment. Geometry learning affects students’ ability to connect mathematical ideas, both in the discipline and to other disciplines as well as the real world. The results of this study show that Primary School students still had difficulties in learning and understanding geometry. Therefore, it was necessary to develop a method that would improve students’ understanding of geometrical concepts, which were important because they were highly relevant to students’ daily life. The present study aimed to explore geometrical concepts found in Sumedang tofu and <em>bongsang</em>. Descriptive qualitative approach was implemented, in which the data was gathered through observation, literature study, and interviews. The findings indicated that geometrical concepts could be found in Sumedang tofu and <em>bongsang</em>. Those concepts could be used in mathematics lessons in primary school to provide meaningful learning for students. The results of this study could be used as a foundation to develop an ethnomathematics learning in primary school level.</p><p> </p>2023-01-18T18:02:31+07:00Copyright (c) 2023 Prima: Jurnal Pendidikan Matematikahttps://jurnal.umt.ac.id/index.php/prima/article/view/7379MISCONCEPTIONS OF PROSPECTIVE MATHEMATICS TEACHER IN LINEAR EQUATIONS SYSTEM2023-01-18T18:02:31+07:00Dini Kinati Fardahdinifardah@unesa.ac.idEvangelista Lus Windyana Palupievangelistapalupi@unesa.ac.id<span>Misconceptions are still a problem in learning mathematics. The causes are very diverse, ranging from the cognitive abilities of students who are not good at mathematics to the teacher who is the trigger for this misconception. The misconception diagnostic test benefits readers as a reference and pressure point in conveying certain concepts that are prone to misconceptions. This study aims to diagnose the occurrence of misconceptions and to analyze the types of misconceptions in 29 prospective mathematics teachers on the two-variable (SPLDV) and three-variable (SPLTV) linear purchasing system materials. A test to detect conceptual errors was given to these prospective teacher students to diagnose conceptual errors that occurred when they studied SPLDV in junior high school and SPLTV in high school before being given linear sales system material in Elementary Linear Algebra courses. The results show that there are still classificational, correlational, and theoretical misconceptions. Theoretical misconceptions that occur in students are related to the definition of misconceptions and related to the definition and types of SPL solutions. Classificational misconceptions occur when students classify examples and non-examples of a given linear sales system. Correlational misconceptions occur in students, namely students cannot connect a statement related to SPLDV with its graphical representation of the statement given, also students are not precise in compiling mathematical models of everyday problems given so the solutions obtained are incorrect.</span>2023-01-18T18:02:31+07:00Copyright (c) 2023 Prima: Jurnal Pendidikan Matematikahttps://jurnal.umt.ac.id/index.php/prima/article/view/7341MATH ANXIETY AS A PREDICTOR OF MATH COMMUNICATION ABILITY ON SENIOR HIGH SCHOOL STUDENTS2023-01-18T18:02:31+07:00Dinda Haniyahhaniyah.dinda99@gmail.comHikmatul Khusnahikmatulhusna@gmail.com<p>Math anxiety is one of the aspects that plays a role in the form of talent that students have, so that if math anxiety can be controlled properly, so this aspect also has an important effect on students' math communication ability. This research aims to determine math anxiety as a predictor of the math communication ability of high school students. The sample in this research was at SMAN 10 Bekasi in semester 1 of the 2022-2023 academic year class XII. The research method used is the correlational research method. The sampling technique used is Simple Random Sampling. The sample taken was 58 students. The results of the research instrument test were obtained by testing the math communication ability test instrument as many as 5 questions and the math anxiety questionnaire instrument as many as 32 questions. This research have only examines one prediktor on math communication ability not only math anxiety many other factors affect math communication ability which has 91.2% and math anxiety as a predictor is also very small with 8.8% because it is effected by other factors So, students' communication ability cannot yet be said to be ideal. Because the average student does not have the math communication ability to ask questions and in solving math problems still depends on his friends. Meanwhile, students who have good grades are mostly due to often practicing questions at home and have the active to ask the teacher.</p>2023-01-18T18:02:31+07:00Copyright (c) 2023 Prima: Jurnal Pendidikan Matematikahttps://jurnal.umt.ac.id/index.php/prima/article/view/7437DEVELOPMENT OF MATHEMATICS INTERACTIVE MULTIMEDIA WITH SCRATCH TO ENHANCE STUDENT'S MATHEMATICS UNDERSTANDING ABILITY2023-01-18T18:02:31+07:00Ratu Sarah Fauziah Iskandarratusarah1704@gmail.comBambang Avip Priatna Martadiputraratusarah1704@gmail.comNurjanah Nurjanahratusarah1704@gmail.com<p>Interactive media is something that is important to be developed in order to improve students' mathematical understanding abilities. One of the learning media used is scratch. Scratch-assisted learning media on rank numbers material is made to make it easier for students to understand concepts and to increase student interest in learning, by studying it is expected to be able to give birth to creative students in making learning media based on scratch animation. The research design used in this research is the research design of 4D model development (Four D Models). This includes 4 stages, namely the definition, design, development and dissemination stages, which the researcher then simplifies by changing from four stages (4D) to three stages (3D), namely: defining, designing and developing.</p>2023-01-18T18:02:31+07:00Copyright (c) 2023 Prima: Jurnal Pendidikan Matematika
