Abstract

Conceptual and procedural errors are still frequently found among prospective mathematics teachers when solving mathematical problems. However, the questions commonly used to assess conceptual and procedural understanding tend to be routine in nature, which may not adequately reflect students’ mastery of the material. Therefore, this study aims to analyze the conceptual and procedural errors made by prospective mathematics teachers when solving a non-routine problem related to the topic of reflection. This research employed a qualitative descriptive approach, involving 16 students from the Mathematics Education program at UIN Mahmud Yunus Batusangkar. The research instrument consisted of a single non-routine problem administered after the students had studied the topic of reflection. The results showed that 11 students were able to solve the problem correctly, while the remaining 5 made errors. The identified conceptual errors included a lack of understanding of the concepts of reflection and linear equations, as well as incorrect use of mathematical notation. Procedural errors involved computational mistakes and carelessness in forming equations. These findings indicate that strengthening students' conceptual and procedural understanding is still necessary before directing them toward developing higher-order thinking skills.

Abstract

This community service program aimed to enhance both the understanding and application of Higher-Order Thinking Skills (HOTs) in mathematics instruction for participating teachers. Employing a targeted professional development approach informed by the Community-Based Participatory Research (CBPR) framework, the program equipped 21 mathematics teachers from Musyawarah Guru Mata Pelajaran (MGMP) in Aceh Tengah District, Indonesia, with the necessary knowledge and pedagogical strategies to foster and cultivate high-level thinking skills in their students. The program demonstrably improved teachers' knowledge, skills, and commitment towards implementing HOTs-oriented instruction. While areas like solving HOTs questions necessitate further attention, the overall results suggest success, paving the way for continued advancements in promoting deep-thinking and problem-solving skills in mathematics education. Analysis of the data reveals a positive impact of the program on teachers' understanding of HOTs. While areas such as problem-solving and critical thinking require further development, the program evidently achieved its goals of raising awareness, knowledge, and application skills related to HOTs. Building upon this foundation, future interventions can delve deeper into these advanced skills, further empowering teachers to cultivate critical thinking and problem-solving abilities in their students.

Abstract

This paper provides an overview of Televisi Edukasi, a Television program and channel developed by the Ministry of Education and Culture to provide learning support. Televisi Edukasi has been active for a long time in Indonesia that can reach remote and outer areas with the help of satellite transmitters. Has content for educational and teaching activities as well as information about the policies of the Ministry of Education and Culture. Televisi Edukasi content can be used as content or learning material in the classroom, for the deepening of learning material either done in class with the subject teacher, studying at home under the guidance of the teacher or independent student learning. The government utilizes Televisi Edukasi to support learning that took place during the Covid Pandemic 19 period. With the help of Relay from TVRI, students can watch learning shows that have been made by Televisi Edukasi. However, efforts need to be made to increase the utilization of Televisi Edukasi programs both during the Pandemic and post-pandemic periods, as in fact there are still many limitations that occur so that education has not been optimally utilized in Indonesia both in structured learning activities and also in student independent learning activities.

Abstract

Salah satu penyebab kesulitan dalam pengajaran matematika pada tingkat sekolah dasar adalah terbatasnya media pembelajaran yang tersedia. Padahal, banyak potensi di lingkungan sekitar yang dapat dikembangkan sebagai media pembelajaran matematika, seperti kopi yang merupakan komoditas utama di Kabupaten Aceh Tengah. Kegiatan ini bertujuan untuk membekali para mitra dampingan, yakni guru-guru SD, dengan kemampuan mengembangkan media pembelajaran berbasis kopi atau lingkungan sekitar, sesuai dengan implementasi Kurikulum Merdeka. Metode yang digunakan adalah Service-Learning. Mitra dampingan adalah 25 orang guru SD anggota PGRI Kabupaten Aceh Tengah, dan seluruh kegiatan berlangsung dari Agustus 2024 hingga Oktober 2024. Hasil dari kegiatan pendampingan ini menunjukkan peningkatan pemahaman peserta terhadap implementasi Kurikulum Merdeka, keterampilan dalam menyusun Alur Tujuan Pembelajaran (ATP), serta kemampuan menyusun modul pembelajaran dengan menggunakan media dari kopi atau lingkungan sekitar, dan mempraktikkannya dalam bentuk kegiatan pembelajaran dengan rekan sejawat. Selain itu, melalui kegiatan Pengabdian Kepada Masyarakat (PKM) ini telah terjalin kerja sama antara Fakultas Tarbiyah IAIN Takengon dan PGRI Kabupaten Aceh Tengah, yang dituangkan dalam nota kesepahaman sebagai dasar dalam melaksanakan kegiatan secara bersama-sama terutama dalam bentuk Tridharma Perguruan Tinggi.

Abstract

Children with special needs (Heward) or ABK are children with special characteristics that are different from children in general without always showing mental, emotional or physical disabilities, which are included in ABK, including: blind, deaf, mentally retarded, quadriplegic, hearing impaired, learning difficulties, behavioral disorders, gifted children, children with health problems. Life skills have many definitions and are often misinterpreted, only limited to the skills of producing something, for example, handicrafts, weaving and so on. The purpose of this service is to increase the level of relevance between education and real life, so that after graduating or graduating from a special school or special school, children with special needs are expected to be more independent. The method used in this service is by way of lectures, demonstrations, questions and answers and training on the implementation of Life Skills life skills education for children with special needs, namely by delivering material, educational games, and motor games. The result of this service is that children with special needs become more enthusiastic about participating in activities because the activities are not monotonous and not boring. Children with special needs also show proficiency in every activity they carry out. Children become more capable of forming good life skills.

Abstract

Penelitian ini mengkaji relasi antara tradisi minuman konau dan munculnya perilaku kriminal dalam upacara adat Sampolawa di Kabupaten Buton Selatan melalui perspektif kriminologi budaya. Konau merupakan minuman tradisional yang memiliki makna simbolik dan spiritual kuat sebagai medium solidaritas sosial, legitimasi ritual, serta pengikat hubungan antara manusia, leluhur, dan alam dalam berbagai ritus adat seperti mata bembe, piumbasia, dan piharoa’a. Namun, konsumsi konau yang berlebihan dalam suasana euforia ritual menunjukkan adanya ambivalensi, karena berpotensi memicu perilaku agresif dan tindak kriminal seperti perkelahian dan penganiayaan. Penelitian ini menggunakan metode hukum normatif-empiris dengan mengombinasikan analisis norma hukum pidana dan konsep kriminologi budaya dengan temuan lapangan berupa wawancara dan observasi terhadap praktik adat masyarakat Sampolawa. Hasil penelitian menunjukkan bahwa kriminalitas yang muncul tidak semata-mata dipahami sebagai pelanggaran hukum positif, melainkan sebagai fenomena kultural yang lahir dari emosi kolektif, simbolisme ritual, dan legitimasi adat. Masyarakat adat cenderung merespons konflik melalui mekanisme hukum adat yang bersifat restoratif dan berorientasi pada pemulihan keseimbangan sosial. Oleh karena itu, penelitian ini menegaskan pentingnya pendekatan integratif antara hukum adat dan hukum positif dalam mengelola kriminalitas budaya tanpa mengabaikan pelestarian tradisi lokal.
