Subahnale dan Rang-rang Pembelajaran Matematika SMP

The purpose of this research is to find mathematical concepts in the cultural heritage of songket cloth and how to apply them as a medium for learning mathematics in junior high schools. The results of this study can be used as a reference for junior high school teachers to choose culture-based learning media related to student life, especially in Lombok. This research is an ethnomathematical research with the research method used is a qualitative research method with an ethnographic approach. The research was conducted in September, October, and November 2021 in Sukarara village, Lombok, West Nusa Tenggara. The subjects in this study were craft works in the form of songket cloth and songket weavers who were active in the village of Sukarara which consisted of three weavers. Data were collected by documentation, document observation, and interviews. The documents obtained were then analyzed related to the content of the mathematical concepts contained therein. The conclusion of this study is that the quality of mathematics learning can be improved by using the traditional songket subahnale cloth as a medium or learning aid. Some mathematical concepts that can be learned with songket subahnale as the medium are congruence, similarity, perimeter of flat shapes, area of flat shapes, folding symmetry, comparisons, pattern tracing. Songket fabrics that can be used as media are songket subahnale woven fabrics with geometric motifs such as diamond motifs, rang-rang motifs, and hexagons

The City

In the 2019 survey, 82.2% of teachers never participated in media training, especially learning media based on geogebra technology. Meanwhile, 92.8% of teachers stated that mathematics requires learning media. The low quality of education in NTB requires special attention from both the government and the private sector, so it is important to conduct technology-based learning media training in order to improve the quality of education, especially improving the quality of teachers. The training was carried out using offline and online methods for two days, 19 and 20 August 2021 at SMPN 16 Mataram. The training was attended by 22 participants from junior high school mathematics teachers in the city of Mataram. In the implementation of the training, an evaluation was carried out using questionnaires and observations. The conclusions from the results of the service were as follows: Geogebra training as a medium for learning mathematics for SMP teachers in the city of Mataram in 2021 received a very good response and was well received by the teachers. Geogebra training as a medium for learning mathematics for junior high school teachers in the city of Mataram in 2021 is very in line with what is expected by mathematics teachers in the City of Mataram and increases teacher competence in the context of applying technology in learning to develop technology-based mathematics learning media.

Achievement In Mathematics

This study titled as The Effect of Disposition on Student Mathematics Learning Achievement in Medan State 28 Junior High School. In this study, disposition is an independent variable and achievement in mathematics learning is a dependent variable. Mathematical disposition is a change of student’s tendency in assuming and behaving toward mathematics, also their act when learning mathematics. For example, when students can solve non-routine problems, their behavior and assumption of mathematics as a student become more positive. The more mathematical concepts understood, the more students convinced that mathematics can be mastered. Based on theory, there are many factors that influence student's achievement in mathematics learning. In this study, researcher only took disposition factor. This research took place at Medan State 28 Junior High School which located at Karya Bersama St. No. 17 Medan Johor. The method of this study is a quantitative method with all of VIII class students which amount to 273 students and divided into 8 (eight) study groups. The data obtained by giving a questionnaire consisting of 19 statements. The data then analyzed by using simple linear regression analysis. The data analysis was performed by using SPSS 21 software for Windows. From the results of this study, it can be concluded that there is an effect of disposition on students' achievement in mathematics learning or in other words, students' achievements in mathematics learning are influenced by the disposition attitudes that students have in mathematics learning. The influence occurs in the disposition of achievement in mathematics learning is positive, that is equal to 6.6%.Keywords: Disposition, Mathematics Learning Achievement.

Mathematical Concepts

Pemahaman Konseptual Matematis (PKM) memiliki peran penting karena dengan kemampuan ini siswa mudah dalam membangun hubungan untuk memahamai ide dan konsep baru. Kemampuan PKM ini dapat ditumbuh-kembangkan melalui pembelajaran di kelas. Untuk mencapai kecakapan tersebut, pembelajaran perlu memperhatikan keberagaman siswa karena pembelajaran yang mengakomodasi keberagaman menjadi lebih efektif, efesien, dan menarik. Keberagam tersebut dapat berupa Gender (G), Kemampuan Awal Matematika (KAM) dan Gaya Belajar Matematis (GBM) siswa. Salah satu pendekatan pembelajaran yang mengakomodir keberagaman ialah pembelajaran pendekatan Rigorous Mathematical Thinking (RMT). Artikel ini bertujuan untuk mengkaji kemampuan PKM siswa SMP yang memperoleh pembelajaran pendekatan RMT ditinjau dari : a). Gender, b). KAM siswa, dan c). GBM siswa. Penelitian ini merupakan penelitian eksperimen pada siswa SMP di salah satu sekolah di Bandung. Salah satu hasil yang penting adalah dengan pembelajaran ini menjadikan siswa dengan KAM sedang dan rendah dapat mencapai kemampuan yang baik. The Effect of Rigorous Mathematical Thinking (RMT) Learning Approach On Students’ Understanding of Mathematical Concepts AbstractAn understanding of mathematical concepts (PKM) has an important role because with this ability students are easy in building relationships to understand new ideas and concepts. The ability of PKM can be grown-developed through learning in the classroom. To achieve these skills, learning needs to pay attention to the diversity of students because learning that accommodates diversity becomes more effective, efficient, and engaging. Such diversity can be Gender (G), An initial mathematical ability (KAM) and students’ mathematics learning styles (GBM). One approach to learning that accommodates diversity is the Rigorous Mathematical Thinking (RMT) learning approach. This article aims to examine the ability of junior high school students who have learned RMT approach in terms of: a). Gender, b). students’ KAM, and c). students’ GBM. This research is an experimental research on junior high school students in one school in Bandung. One important result is that this learning engages students with medium and low of KAM able to achieve good abilities.

Question And Answer

WORKSHOP OF STUDENT WORKSHEET COMPILATION FOR MATHEMATICS TEACHERS OF JUNIOR HIGH SCHOOL IN TELUKJAMBE, KARAWANG. The majority of math teachers use Student Worksheet (LKS) traded by the publisher’s distributor. The contents of LKS are less interesting and innovative. LKS does not help the participants to collect the material and learn their interest in mathematics learning. None or steps in the LKS which allows participants to discuss the concepts they are studying. According to the theory of constructivism a learner in learning must be able to mengkontruksi knowledge to understand a material. On that basis, we prepare training on the preparation of LKS. Activities undertaken through socialization with methods that in this devotion program is a method of lectures and exercises supported by discussion and question and answer. Output target after the implementation of this Program is the increase of the ability of Junior High School teachers who teach in class VII in preparing the LKS as well as the product of LKS.
