Abstract

The selection of material that is contextual and based on student culture is essential for improving the quality of learning mathematics. This study aims to examine, explore, and explore Calung Banyumasan music as a source of learning mathematics that is contextual and easy to understand. This research is qualitative with an ethnographic approach because it examines a particular cultural system (Banyumasan art) from an ethnomathematics perspective. The subjects in this study were three humanists, practitioners, and mathematicians related to Calung Banyumasan musical arts, and the research object was Calung Banyumasan instruments. Data collection methods use in-depth interviews, observation, documentation, and field notes. The data analysis method was carried out descriptively based on the results of the meaning and translation of the phenomena found based on the results of the informant's conception, the results of observations combined with the researcher's language after an in-depth understanding was carried out. Triangulation and Forum Group, Discussion was used to test the data's validity and the effects of data analysis. The research results show that Calung Banyumasan music art has mathematical wealth, especially in Geometry (parallelism, congruence, plane shapes, and curved side shapes) and Algebra (compound functions, arithmetic sequences, series, and inverse comparisons of values). Besides that, Calung Banyumasan music also has a lot of valuable philosophical content for human life.

Abstract

The study aimed to determine the effect of the implementation of the Aptitude Treatment Interaction learning model and its effectiveness on the mathematical thinking skills of SMPN 1 Ajibarang students on the topic of Opportunity, between the ATI (Aptitude Treatment Interaction) experimental class and the control class with the cooperative learning model. This type of research was a quasi-experimental design with two control experiment groups, a pre- test and a post-test design. The results showed differences in student learning outcomes between the two classes, as evidenced by the results of the t-test (2 parties), where the significance value was 0.009 0.025. Thus, there was an average difference between the experimental and the control classes. So, the application of the ATI (Aptitude Treatment Interaction) learning model in the experimental class affects the creative thinking ability of SMP for eighth grader students on the subject of opportunity compared to the control class

Abstract

This article discusses the definition and properties of p-hiponormal operators for p>0. To investigate the properties of p-hiponormal operators, the concept of positive operators, partial isometry operators, decomposition of operators, and existence of partial isometry operators for any operator on a Hilbert space are required.

Abstract

The research outlines the computational thinking process that prospective mathematics teachers use to solve PISA model problems. The Department of Mathematics Education conducted the research on 32 students in the Basic Mathematics course. This qualitative approach research used research instrument such as a computational thinking skill test and interview guidelines. The researchers grouped students into low, medium, and high ability categories based on previous tests. The researchers took as many informants as possible from each category using purposive sampling techniques. The applied technical data analysis included data reduction, presentation, and conclusions. The computational thinking process consisted of orientation, abstraction, decomposition, algorithms, and evaluation. The study provided several results, including high- and medium-category students being able to write information at the orientation and algorithm stages. The difference between the computational thinking processes of low- and medium-category students lies in the orientation stage and algorithms. Low-category students had to be more detailed in recording every step of the problem-solving process, as they could not write down all the primary information and problems. Those three lied in the orientation stage, the process of identifying information, and the key problems at the orientation stage as an early and important aspect of the computational thinking process. This research facilitates teachers improve students' computational thinking in solving high-level problems.         Keywords: computational thinking process, PISA model problems, problem-solving DOI: http://dx.doi.org/10.23960/jpmipa/v25i2.pp961-971

Abstract

Abstrak Kepercayaan diri merupakan salah satu aspek afektif yang penting dalam meningkatkan komunikasi matematis. Penelitian ini bertujuan untuk menganalisis proses komunikasi matematis calon guru matematika dalam memecahkan masalah berdasarkan kepercayaan diri. Metode yang digunakan adalah kualitatif. Subyek penelitian adalah mahasiswa Pendidikan Matematika, Universitas Muhammadiyah Purwokerto. Instrumen penelitian terdiri dari angket, tes, dan wawancara. Hasil angket kepercayaan diri dikategorikan dalam tinggi, sedang, dan rendah. Setiap kategori mengambil satu orang sebagai responden. Analisis data menggunakan tahap reduksi, penyajian, dan kesimpulan. Hasil penelitian menunjukkan siswa kategori kepercayaan diri tinggi dan sedang memiliki karakteristik proses komunikasi yang baik. Siswa menggunakan simbol dengan tepat untuk menjelaskan informasi dan masalah yang diketahui serta menuliskan jawaban secara terperinci. Siswa kategori kepercayaan diri rendah membutuhkan bantuan untuk menerjemahkan informasi dan simbol matematika. Hal ini mengakibatkan kesulitan dalam menyelesaiakan masalah dengan tepat. Kondisi ini menunjukkan bahwa tahap identifikasi informasi dan representasi masalah sebagai kunci awal proses komunikasi matematika. Abstract Self-confidence is one of the important affective aspects in improving mathematical communication. This study aims to analyze the mathematical communication process of prospective mathematics teachers in solving problems based on confidence. The method used is qualitative. The subject of the study is a student of Mathematics Education, Universitas Muhammadiyah Purwokerto. The research instrument consisted of questionnaires, tests, and interviews. The results of the confidence questionnaire are categorized into high, medium, and low. Each category takes one person as a respondent. Data analysis uses reduction, presentation, and conclusion stages. The results showed that students in the high and medium confidence categories had the characteristics of a good communication process. Students use symbols appropriately to explain known information and problems and write down answers in detail. Students in the low confidence category need help translating mathematical information and symbols. This results in difficulties in solving problems appropriately. This condition shows that the stage of information identification and problem representation is the initial key to the mathematical communication process.
