Abstract

Pembelajaran berdiferensiasi merupakan opsi untuk menciptakan keadilan dalam pembelajaran. Sehingga setiap peserta didik mendapat konten, proses dan hasil yang sama. Penelitian ini bertujuan untuk mendeskripsikan pembelajaran berdiferensiasi untuk melayani kebutuhan peserta didik kelas VIII.C pada materi bangun datar di SMPN Lorotuan. Jenis penelitiannya adalah deskriptif kualitatif. Sebelum melaksanakan pembelajaran berdiferensiasi di kelas terlebih dahulu guru melakukan asesmen diagnostik dengan menggunakan angket kebutuhan belajar untuk mengidentifikasi kebutuhan belajar peserta didik. Identifikasi ini dengan maksud agar guru memiliki data untuk memutuskan strategi diferensiasi pembelajaran apa yang akan diterapkan. Dari hasil asesmen diperoleh data 10 peserta didik memiliki kebutuhan belajar (gaya belajar) visual, 6 peserta memiliki kebutuhan belajar auditori dan 4 peserta memiliki kebutuhan belajar kinestetik. Berdasarkan data ini kemudian guru memutuskan untuk menggunakan diferensiasi konten dan proses untuk melayani kebutuhan peserta didik. Untuk mengukur tercapainya tujuan pembelajaran dengan pembelajaran diferensiasi maka dilakukan tes matematika menggunakan 3 butir soal uraian untuk mengukur 3 indikator yang berbeda. Hasil yang diperoleh secara klasikal menunjukan 85% peserta didik yang telah terlibat dalam pembelajaran berdiferensiasi (konten dan proses) mencapai KKM. Persentase sesuai kelompok kebutuhan belajar: visual 70% mencapai KKM, auditori 100% mencapai KKM dan kinestetik 100% mencapai KKM. Berdasarkan hasil penelitian ini kama diharapkan guru menerapkan pembelajaran diferensiasi di kelas agar tercipta kegiatan pembelajaran yang efektif, menyenangkan dan adil sesuai kebutuhan belajar murid.

Abstract

Community Service Activities are based on the results of situation anlysis with mathematics teachers about what they need to be able to attract students' interest in learning mathematics and be able to create a learning process that produces. Ethnomatematics was chosen because it is rich in cultural values, contextual interactions, and in accordance with the 2013 Curriculum which emphasizes improving creative thinking skills and character education through integration in mathematics learning. The cultural element designated in this activity was lopo, one of the traditional Timorese houses that is close to the daily lives of students. Activities carried out in three stages, namely preparation, implementation, and evaluation. In preparation, the Team with the Mathematics Education Study Program students held a meeting that would be used when learning in class. Make this a learning medium to help students understand mathematical concepts specifically geometry. Learning begins with a brief description of lopo as a cultural artifact and then continues with a non-uncertain mathematical discussion through direct search and measurement on the lopo mockup. Overall this activity went well. In the evaluation activities, the subject teacher and students expressed enthusiasm for the activities that had been carried out. Learning mathematics using teaching aids has been done in class, but involving culture in learning mathematics is a new experience and adds insight to teachers and students of mathematics who are close to their daily lives. Kegiatan Pengabdian kepada Masyarakat ini didasarkan pada hasil analisis situasi bersama para guru mata pelajaran matematika tentang dibutuhkannya suatu pendekatan yang dapat menarik minat para siswa dalam belajar matematika dan mampu menciptakan suatu proses pembelajaran yang bermakna. Pendekatan etnomatematika dipilih sebab kaya akan nilai budaya, bersifat kontekstual, dan sejalan dengan Kurikulum 2013 yang menekankan pada pengembangan kemampuan berpikir ilmiah dan pendidikan karakter melalui integrasinya dalam pembelajaran matematika. Unsur budaya yang diangkat dalam kegiatan ini yaitu lopo, salah satu rumah tradisional Suku Timor yang dekat dengan kehidupan keseharian para siswa. Kegiatan dilakukan dalam tiga tahapan yaitu tahap persiapan, pelaksanaan, dan evaluasi. Di tahap persiapan, Tim bersama mahasiswa Program Studi Pendidikan Matematika merancang maket berbentuk lopo yang akan digunakan pada saat pembelajaran di kelas. Maket ini berfungsi sebagai media pembelajaran untuk membantu para siswa dalam mempelajari konsep-konsep matematika khususnya geometri. Pembelajaran diawali dengan deskripsi singkat tentang lopo sebagai artefak budaya dan kemudian dilanjutkan dengan eksplorasi unsur-unsur matematis melalui pengamatan dan pengukuran langsung pada maket lopo. Secara keseluruhan kegiatan ini berjalan dengan baik. Pada kegiatan evaluasi, guru mata pelajaran dan para siswa mengungkapkan antusiasme terhadap kegiatan yang telah dilaksanakan. Mempelajari matematika menggunakan alat peraga sudah pernah dilakukan di kelas, namun melibatkan budaya dalam pembelajaran matematika merupakan suatu pengalaman yang baru serta menambah wawasan para guru dan siswa bahwa matematika sebenarnya dekat dengan kehidupan mereka sehari-hari.

Abstract

Students need teachers with a deep understanding of mathematical concepts to improve their mathematical knowledge and achievement. The observation results of several elementary school teachers showed that they still have a lack of understanding of the geometry concepts. This research is an exploratory study with a qualitative approach that aims to describe the performance of elementary school teachers in understanding the concepts of triangles and squares. The participants in this study were elementary school teachers across Soe City District. A description test deals with the geometry concept of two-dimensional shapes that were implemented to determine the most appropriate teachers to participate in the study. Thirty-three teachers were then selected based on this preliminary test results. In-depth interviews were also conducted with the participants. The data analysis showed that the participants had a lack of understanding of the concept of two-dimensional shapes and necessary arithmetic skills. Moreover, the data suggested that the participants held various perceptions regarding their understanding of certain concepts based on their experience in teaching the mathematical concept. Based on these results, some programs are recommended to improve professionalism and pedagogical competencies, such as a refresher training program for basic mathematical material and training in teaching aids used. These programs are expected to help prepare elementary school teachers in teaching mathematics.

Abstract

The gap in the decline in PISA scores is likely due to an abstract and contextually irrelevant approach to teaching mathematics, which often fails to connect everyday experiences that utilize the potential of local wisdom to make learning more engaging and culturally relevant. This research aimed to develop mathematics learning materials that integrate local wisdom to improve students' mathematical literacy skills. The study employed the Research and Development (R&D) method with the ADDIE development model. The developed learning materials incorporated elements of Timor local culture, including traditional houses, handwoven fabrics, and traditional games, as contextual tools to enrich the learning experience. The quality of the developed product was evaluated for three aspects: validity, practicality, and effectiveness. The validation results showed an average score of 93.1%, which is included in the very valid category. Product implementation showed a significant increase in trial results, with all students meeting the minimum competency criteria after using the learning materials. The final score of students' responses after using this developed product is 96.93%, categorized as very practical. The average N-Gain score of 0.76 significantly increased students' mathematical literacy skills. Feedback from students highlighted that learning materials inspired by local wisdom made the learning process more engaging and relatable. Teachers appreciated the inclusion of cultural elements, noting that they facilitated a deeper connection between mathematical concepts and students' everyday experiences. The research underscores the transformative potential of a culture-based approach in mathematics education.

Abstract

Buna is one of the woven motifs from Insana, East Nusa Tenggara Province that uses geometric motifs like a rhombus. Rhombus is a challenging material so students only memorize the formula without understanding the concept.  In order to overcome this problem, a weaving learning based on ethnomathematics has been proposed. The purpose of this study is to understand the impact on the learning achievement of students of the implementation of a realistic mathematical approach based on ethnomathematics. This is a quantitative study using a one-group pretest-posttest design. The population for this study is all fifth-grade students of SDN Bestobe, Insana District. Pretest and posttest results obtained are used for the analysis. The statistical test used is a paired sample t-test. The results show that the implementation of realistic mathematical learning based on ethnomathematics has a substantial influence on the learning achievement of mathematics students. These results contribute to adding empirical evidence related to the relationship between Ethnomathematics-based Realistic Mathematics Education approaches to student achievement.

Abstract

Students who have special needs also have the right to obtain an education as a provision for life, just like regular students. However, several learning tools for them are still very few. It is because some researchers always focus on standard students. Therefore, this study aims to develop visual-based mathematics teaching materials on integer arithmetic operations, one of which is deaf students. The development model used is a modified development model from the 4D model. Teaching materials that have been developed and tested on deaf class VIII students are suitable for use as a learning medium because they meet the criteria of being valid, practical, and effective. Valid because the average value of the three validators is 3.85. Furthermore, the practical standard is because the percentage of the average response score of students obtained is 80%. Finally, the effective criterion is that the average score of students trying to solve the test questions is 81. The results of this study contribute to providing alternative teaching materials for deaf students.
