Abstract

This study aims to describe the increase of students' mathematical understanding ability in learning the two-variable linear equation system (SPLDV) and the two-variable linear inequality system (SPTLDV) with Android GeoGebra media reviewed by gender. This experimental quasi research is one group pretest postest design. The sample in this study was a class XI of 32 students with Purposive Random Sampling techniques. Data collection in this study uses an instrument for a mathematical understanding ability test in the form of a description. The results of the study can be concluded in the learning of Android GeoGebra, the mathematical understanding of male students is significantly different from the mathematical understanding of female students. It means that in learning the Android GeoGebra Improvement of the Mathematical Understanding Ability of Male Students is greater than female students. Thus it can be concluded that in the learning of Android GeoGebra, an increase in the mathematical understanding of male students is better than female students.

Abstract

Student problem-solving is fundamental in mathematics because, in problem-solving, students can explore the subject by applying the concepts to real-world problems. NHT is one of the learning models where students can work together to solve problems and an effective method to encourage students to become more involved and think critically. This study aims to determine the effect of the Numbered Heads Together learning model on problem-solving 101 students in class X SMA Negeri Punung in 2022/2023. The research method used is pseudo-experimental research because researchers want to know the effect of the NHT model on student problem-solving. Data analysis using Anava showed that the significance value <0.05. The anava results showed an effect of the learning model on students' problem-solving ability. After further testing, there is a difference in the average value of students subjected to NHT treatment higher than students subjected to TPS and conventional treatment. Based on the study results, the NHT model is more effective in improving students' problem-solving ability in class X SMA Negeri Punung in 2022/2023.

Abstract

Teaching materials are materials used for learning. Teaching materials are certainly different from reference books. This is because the teaching materials have been adapted to the characteristics of the students to be taught. Teaching materials created and developed by teachers can be submitted for ISBN and copyright. This service activity follows the implementation of action activities consisting of Preparation/Planning, Implementation, Evaluation and Reflection. As a result of this activity, each participant has knowledge and insight about the basic concepts related to submitting ISBN and IPR learning modules.

Abstract: Promoting the Pancasila Students Profiles through Mathematics Education in Schools: Ethnomathematics Roles. The present mathematics curriculum in Indonesia (IND) places a strong emphasis on the creation of a Pancasila student profile in order to ensure that pupils are learning mathematics in a meaningful way. Objective: This paper suggests an integration of ethnomathematics into the formal mathematics curriculum as one approach to dealing with these learning issues. It is based on a literature assessment of studies on ethnomathematics, mathematics education, and Pancasila student profile. Methods: The literature review method used with a narrative review design. A total of 28 articles were selected for publication at the final stage of the review process. Findings: In light of the preceding explanation, it is clear that ethnomathematics plays a part in the formal school mathematics curriculum since the context-relevant and constraint-filled problem-solving techniques give many abstract mathematical notions the required contextual meaning.Keywords: ethnomathematics, mathematics education, pancasila student profiles.Abstrak: Mendorong Profil Siswa Pancasila melalui Pendidikan Pendidikan Matematika di Sekolah: Peran-Peran Etnomatematika. Kurikulum matematika di Indonesia saat ini memberikan penekanan yang kuat pada penciptaan Profil Pelajar Pancasila untuk memastikan bahwa siswa belajar matematika dengan cara yang bermakna. Tujuan: Artikel ini menawarkan integrasi ethnomathematics ke dalam kurikulum matematika formal sebagai salah satu pendekatan untuk menangani masalah pembelajaran. Hal ini didasarkan pada kajian literatur studi tentang ethnomathematics dalam pendidikan matematika, dan Profil Pelajar Pancasila. Metode: Metode kajian literatur digunakan dengan desain kajian naratif. Sebanyak 28 artikel dipilih untuk diterbitkan pada tahap akhir proses peninjauan. Temuan: Berdasarkan temuan dan penjelasan, maka jelas bahwa ethnomathematics dapat berperan dalam kurikulum matematika sekolah formal karena teknik pemecahan masalah yang relevan dengan konteks dan permasalahan memberikan banyak gagasan matematika abstrak berdasarkan makna kontekstual.Kata kunci: ethnomathematics, pendidikan matematika, profil pelajar pancasila. DOI: http://dx.doi.org/10.23960/jpp.v13.i2.202305

Abstract

Kemampuan berpikir kritis siswa dalam matematika saat ini masih lemah. Penelitian ini bertujuan untuk mengidentifikasi karakteristik kemampuan berpikir kritis matematis siswa dalam menyelesaikan masalah trigonometri. Metode penelitian yang digunakan adalah studi kualitatif dengan desain fenomenologi, melibatkan peneliti sebagai instrumen utama. Penelitian ini menggunakan tes (masalah trigonometri), pedoman wawancara, dan observasi sebagai instrumen non-tes. Subjek penelitian terdiri dari tiga siswa kelas X yang dipilih dengan teknik purposive sampling. Uji keabsahan dilakukan melalui triangulasi metode dan teori, serta analisis data menggunakan teknik induktif. Hasil penelitian menunjukkan bahwa siswa dengan kemampuan berpikir kritis cenderung lebih efektif dan cepat dalam menyelesaikan masalah trigonometri. Mereka memiliki pendekatan unik dalam memecahkan masalah dan fokus pada pencarian jawaban. Pemikiran kritis matematis juga mempengaruhi kemampuan siswa dalam memahami dan menghubungkan informasi yang ada dalam soal. Selain itu, pemikiran kritis matematis berdampak pada pemikiran logis dan daya ingat yang baik, sehingga siswa lebih mudah dalam menentukan formula pemecahan masalah. Students' critical thinking skills in mathematics are currently still weak. This study aims to identify the characteristics of students' mathematical critical thinking abilities in solving trigonometry problems. The research method used is a qualitative study with a phenomenological design involving researchers as the main instrument. This study uses tests (trigonometry problems), interview guidelines, and observation as non-test instruments. The research subjects consisted of three class X students selected by purposive sampling technique. The validity test was carried out through method and theory triangulation and data analysis using inductive techniques. The results showed that students with critical thinking skills tended to be more effective and faster in solving trigonometry problems. They have a unique approach to solving problems and focus on finding answers. Mathematical critical thinking also affects students' ability to understand and relate the information contained in the problem. In addition, mathematical critical thinking impacts logical thinking and good memory, so students find it easier to determine problem-solving formulas.
