Abstract

Penelitian ini bertujuan untuk mengkaji peran media pembelajaran berbasis IT dalam meningkatkan kemampuan komunikasi matematis siswa. Metode yang digunakan adalah studi pustaka dengan menganalisis beberapa penelitian relevan yang dipublikasikan pada tahun 2024 terkait pemanfaatan teknologi informasi dalam pembelajaran matematika. Hasil kajian menunjukkan bahwa berbagai bentuk media berbasis IT, seperti video animasi, e-modul berbasis Android, perangkat lunak matematika, dan model flipped classroom, memberikan kontribusi positif terhadap kemampuan siswa dalam mengekspresikan ide matematis, merepresentasikan konsep, serta mengomunikasikan proses penyelesaian masalah baik secara lisan maupun tertulis. Media berbasis IT memfasilitasi visualisasi dan interaktivitas sehingga membantu siswa memahami konsep matematika yang bersifat abstrak dan mengungkapkannya secara sistematis. Selain itu, penggunaan teknologi pembelajaran juga meningkatkan minat dan keterlibatan siswa dalam pembelajaran matematika yang mendukung perkembangan komunikasi matematis. Namun, efektivitas media berbasis IT sangat bergantung pada ketersediaan infrastruktur, kompetensi guru, dan perancangan pembelajaran yang tepat. Dengan demikian, media pembelajaran berbasis IT dapat diposisikan sebagai sarana strategis untuk meningkatkan kualitas pembelajaran matematika dan kemampuan komunikasi matematis siswa.

Abstract

Penelitian ini bertujuan untuk meningkatkan literasi digital dan kreativitas siswa sekolah dasar melalui pelatihan pembuatan animasi pembelajaran dengan Microsoft PowerPoint. Kegiatan dilaksanakan selama dua hari di SDIT AL-Habib dengan melibatkan 20 siswa kelas 5B. Metode yang digunakan adalah edukatif-partisipatif dengan pendekatan project-based learning. Hasil penelitian menunjukkan peningkatan signifikan dalam kemampuan teknis siswa menggunakan fitur PowerPoint, peningkatan kreativitas dalam menyusun media pembelajaran, serta peningkatan kepercayaan diri dalam mempresentasikan karya. Sebanyak 80% siswa berhasil menguasai materi dengan baik, sementara 20% memerlukan pendampingan intensif. Evaluasi dilakukan melalui observasi partisipasi, penilaian karya, dan presentasi hasil. Kegiatan ini membuktikan bahwa pembelajaran berbasis multimedia dapat meningkatkan minat belajar siswa dan mendukung pengembangan keterampilan abad 21. Disarankan untuk mengadakan pelatihan serupa secara berkelanjutan dengan dukungan fasilitas yang memadai.

Abstract

This study aims to explore and describe the mathematical concepts embedded within the Gedogan Karo weaving loom at the Jamin Gintings National Hero Museum. The primary focus is to identify the application of ethnomathematics in the tool's structure and the process of weaving traditional Karo cloth (Uis Karo). The methodology employed in this research is qualitative with an ethnographic approach. Data were collected through direct observation of artifacts in the museum, technical documentation, and a literature study regarding the weaving techniques of the Karo people to dissect the underlying mathematical elements. The results and discussion indicate an integration of formal mathematical concepts across four main aspects: (1) Geometry, through the formation of parallel lines in the warp threads and perpendicular relationships in the weft threads; (2) Geometric Transformation, evident in the symmetry, reflection, and translation patterns of the Uis Karo motifs; (3) Binary Logic, in the thread-lifting technique that resembles computer algorithm systems; and (4) Trigonometry, in the thread tension mechanism which depends on the leaning angle of the weaver's body. The conclusion of this study is that the Gedogan Karo loom is a manifestation of local wisdom that intuitively applies complex mathematical principles. The author suggests that these ethnomathematical exploration results be integrated into the formal mathematics education curriculum as contextual learning material. This is crucial for increasing students' interest in mathematics while simultaneously strengthening efforts to preserve Karo cultural heritage in the modern era.

Abstract

Background: Many students have difficulty distinguishing between direct and inverse proportion problems. This difficulty can cause interference during problem solving. One form of interference is proactive interference, which occurs when previously learned information disrupts the understanding of new information. In proportion problems, students’ prior knowledge of direct proportion often influences how they approach inverse proportion tasks, leading them to apply incorrect strategies. Aim: This study aims to describe the process of proactive interference experienced by students when solving proportion problems using the Mindsponge framework. Method: This study used a qualitative descriptive approach. The participants were 32 eighth-grade students from Junior High School 3 Malang. The selected subjects were students who could correctly solve direct proportion problems but applied the direct proportion concept when solving inverse proportion problems. Data were collected through proportion problem tests and interviews. Students’ written work was analyzed using indicators from the Mindsponge framework, and the findings were triangulated by comparing students’ work with interview results. Results: The results show that proactive interference occurred at three stages of the Mindsponge framework: environmental, filtering, and mindset. At the environmental stage, students made errors in observing and understanding the problem. In the filtering stage, students incorrectly determined the quantitative relationship between variables. At the mindset stage, students relied on their prior knowledge of direct proportion and frequently used the cross-multiplication strategy. Conclusion: The study indicates that proactive interference occurs when previously learned concepts dominate students’ thinking processes. The Mindsponge framework helps explain how prior knowledge influences the way students interpret and apply new information when solving proportion problems.

Abstract

Background of study: Corporate tax disclosure is an essential element of transparent and sustainable governance, especially in emerging markets where concerns about tax avoidance remain prominent. CSR board committees are expected to play a role in strengthening responsible corporate behavior, including tax-related transparency. Aims and scope of paper: This paper aims to investigate the extent to which CSR board committee characteristics committee existence, member educational background, and member professional experience affect corporate tax disclosure. The scope of the study focuses on technology firms listed on the Indonesia Stock Exchange (IDX), a rapidly expanding sector facing growing expectations for responsible governance and accountability. Methods: The study employs a quantitative research design using secondary data obtained from annual reports and sustainability reports. A purposive sampling approach yielded 40 technology firms. Corporate tax disclosure was measured through a structured disclosure index, while CSR committee characteristics were operationalized using categorical and numerical indicators. Multiple regression analysis was conducted to test the proposed hypothese. Result: : The results show that the existence of a CSR committee, along with the educational level and experience of its members, has a positive and significant effect on corporate tax disclosure. These findings highlight the importance of CSR governance structures in promoting transparent tax practices. Conclusion: The study concludes that enhancing CSR committee competencies can strengthen tax disclosure quality. Firms and regulators should consider reinforcing CSR governance standards to support ethical and sustainable corporate behavior.
