Abstract

Pendidikan inklusif merupakan pendekatan strategis dalam menjamin hak belajar seluruh peserta didik tanpa diskriminasi, termasuk anak berkebutuhan khusus, kelompok marginal, serta peserta didik dengan latar belakang sosial, ekonomi, dan budaya yang beragam. Penelitian ini bertujuan untuk menganalisis perbandingan implementasi pendidikan inklusif dan aksesibilitas pendidikan antara negara maju dan negara berkembang, dengan fokus pada kebijakan, kurikulum, kompetensi guru, pemanfaatan teknologi, serta pendanaan pendidikan. Penelitian menggunakan pendekatan kualitatif melalui metode studi kepustakaan dengan menganalisis buku ilmiah, artikel jurnal bereputasi, laporan lembaga internasional, serta dokumen kebijakan pendidikan nasional dan global. Teknik analisis data dilakukan menggunakan analisis konten untuk mengidentifikasi pola, persamaan, dan perbedaan praktik pendidikan inklusif antarnegara. Hasil kajian menunjukkan bahwa negara maju memiliki sistem pendidikan inklusif yang terintegrasi secara sistemik, didukung kebijakan yang kuat, pendanaan berkelanjutan, kurikulum adaptif, serta pengembangan kompetensi guru yang berkelanjutan. Sebaliknya, negara berkembang masih menghadapi tantangan berupa keterbatasan infrastruktur ramah disabilitas, kesenjangan kompetensi pendidik, distribusi sumber daya yang belum merata, serta kesenjangan akses teknologi pembelajaran. Di Indonesia, meskipun kebijakan pendidikan inklusif telah dikembangkan melalui Kurikulum Merdeka, implementasinya masih menghadapi hambatan struktural dan kontekstual, khususnya di wilayah terpencil. Penelitian ini menyimpulkan bahwa penguatan kebijakan pendidikan inklusif, peningkatan kompetensi guru, optimalisasi teknologi pendidikan adaptif, serta pendanaan yang berkeadilan merupakan kunci utama dalam mewujudkan sistem pendidikan inklusif yang berkelanjutan dan berkeadilan sosial.

Abstract

This study aims to explore the ethnomathematical concept embedded in the traditional musical instrument Serunai Bengkulu, with a focus on its geometric and symmetrical elements. Serunai, a local cultural heritage, has a physical form that reflects mathematical concepts, such as a cylinder, a truncated cone, and a circle. Using a descriptive qualitative approach with ethnographic methods, data were collected through direct observation, interviews with cultural experts, and visual documentation. The results show that parts of the Serunai, such as the funnel, stem, and ornaments, exhibit vertical and rotational symmetry, as well as geometric shapes consistent with mathematics learning materials at the Junior High School (SMP) level. Integrating local cultural elements into mathematics learning can provide a contextual learning experience, increase student interest, and bring mathematics closer to everyday life. These findings support the importance of implementing ethnomathematics in education, particularly in efforts to preserve local culture and to strengthen understanding of mathematical concepts in more meaningful ways. This study also recommends using cultural objects, such as musical instruments. traditional in learning as a contextual medium to introduce the concepts of geometry and symmetry to students.

Abstract

Learning mathematics in the 21st century requires developing critical thinking skills. However, traditional methods still dominate the classroom, such as using textbooks as learning resources and whiteboards as learning media, making it difficult for students to understand triangle congruence visually and dynamically. This research aims to develop animated video media using GeoGebra and Artificial Intelligence (AI) on triangle congruence material for grade IX junior high school students and to describe their validity and practicality. The research uses the Research and Development (R&D) method with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The test subjects were 14 grade IX students and 1 mathematics teacher, with validation sheet instruments and practicality questionnaires. The results showed that the average validity of the media was 90% with the very valid category, while the practicality reached 89.11% with the very practical category. These findings show that GeoGebra and AI-assisted animation videos are feasible alternatives to modern, interactive mathematics learning media that facilitate students’ critical thinking skills in triangle congruence materials.

Abstract

The purpose of this study was to test the effectiveness of the Problem-Based Learning (PBL) model, Virtual Lab-assisted Discovery Learning (DL), and the conventional model on improving problem-solving skills and self-efficacy. The research method used was a quasi-experimental design with a non-equivalent pre-test and post-test control group. The results showed a significant difference in improvement in problem-solving skills between the three groups (p < 0.001). The Virtual Lab-assisted Discovery Learning model provided the highest improvement (an average increase from 26.77 to 57.43), followed by the Virtual Lab-assisted PBL model (an average increase from 26.39 to 55.64) and the conventional model (an average increase from 27.48 to 34.45). Meanwhile, for the self-efficacy variable, although all classes experienced significant internal improvement (p < 0.05), no statistically significant difference was found between the groups (p = 0.741). In conclusion, the use of virtual laboratories in active learning models is effective for visualizing abstract concepts and for training students' systematic, logical thinking. However, self-efficacy growth tends to be evenly distributed across approaches that provide successful experiences.   Keywords: Discovery Learning, Self-Efficacy, Problem-Solving Skills, Problem-Based Learning, Virtual Laboratory

Abstract

Cultural values ​​play a crucial role in shaping a country's education system, encompassing curriculum, learning methods, discipline, and educational objectives. This study aims to analyze the influence of cultural values ​​on the delivery of education through a comparison of the education systems of Finland, Japan, South Korea, and Singapore. The method used in this study is a literature review with a descriptive-comparative approach. Data were obtained from various scientific sources such as journals, books, and international education reports. The results show that each country has educational characteristics influenced by the cultural values ​​of its society. Finland emphasizes equality, freedom, and student well-being, creating a flexible education system with minimal academic pressure. Japan prioritizes discipline, responsibility, cooperation, and respect for others, reflected in school culture and character education. South Korea is influenced by a competitive culture and a strong work ethic, resulting in an education system oriented toward academic achievement. Meanwhile, Singapore integrates the values ​​of pragmatism, multiculturalism, and technological mastery into its education system to support the development of superior and adaptive human resources. This comparison demonstrates that the success of an education system is inseparable from the cultural values ​​that develop within society. Therefore, the development of education in Indonesia needs to consider relevant local cultural values ​​in order to be able to create an education system that is high quality, has character, and is in accordance with the needs of the times.
