Redefinisi Pendidikan Seni: Analisis Psikopedagogis dan Revitalisasi Kearifan Lokal Minangkabau Di Universitas Negeri Padang

2026-01-19T09:01:24+07:00

Fine arts education in higher education is often trapped in a dichotomy between industrial demands and bureaucratic formalism, which potentially triggers an "erosion of meaning" and "psychological exhaustion" within the academic community. This research aims to identify critical gaps between art education practices in the Fine Arts Education Study Program at Universitas Negeri Padang (UNP) and the fundamental psychological needs of students and lecturers. Using a Critical Educational Criticism approach, this study analyzes the institutional ecology, including human resources, infrastructure, and curriculum structure. The findings indicate a systemic neglect of fundamental psychological principles, particularly Self-Determination Theory (autonomy, competence, and relatedness), Subjective Well-being, and the failure to integrate humanistic psychology into the art criticism process. Furthermore, a dissonance was identified between Western educational models and the Minangkabau cultural matrix, leading to identity alienation among students. As a strategic solution, this research proposes the paradigm of "Pendidikan Seni Terapeutik Berbasis Kearifan Lokal" through the revitalization of the "Neo-Surau" model and the "Mamak Akademik" mentorship system. The implementation of the egalitarian "Lingkaran Randai" art criticism format is proposed to create a safe space that humanizes and heals. In conclusion, the integration of modern psychology with local ethnopedagogical values is key to transforming art education into an empowering and sustainable process.

Optimalisasi Minat Baca Siswa melalui Metode Quantum Reading pada Pembelajaran Bahasa Indonesia SD/MI

2025-12-27T06:58:47+07:00

Reading is an important activity in the learning process because through reading, individuals can obtain information, knowledge, and new insights that are useful for their intellectual development. However, based on observations at MI Mambaul Ulum, students' interest in reading is still relatively low. This is evident in the minimal number of students who actively engage in reading, both inside and outside of class. This low interest in reading is influenced by several factors, including the use of ineffective learning methods, inadequate reading facilities, uninteresting teaching materials, and low enthusiasm and motivation among students to participate in reading activities. These conditions have an impact on students' low comprehension of reading materials and suboptimal learning outcomes. Based on these problems, this study aims to increase the reading interest of fourth-grade students at MI Mambaul Ulum through the application of the Quantum Reading method in Indonesian language lessons. The type of research used is Classroom Action Research (CAR) with the Kemmis and Mc. Taggart model, which was carried out in two cycles. The results show that the application of the Quantum Reading method can significantly increase students' reading interest and learning outcomes. In cycle I, the percentage of students' reading interest reached 55.55% with an average learning outcome score of 62.51, which was still in the poor category. Furthermore, in cycle II, there was a significant increase, namely the percentage of students' interest in reading reached 92.59% and the average learning outcome score increased to 82.22, which is in the fairly good category. This shows that the Quantum Reading method is effective in improving the quality of reading learning

Implementasi Discovery Learning Berpendekatan Deep Learning pada Pembelajaran Fisika Siswa SMP

2025-12-11T10:11:43+07:00

Students' low conceptual understanding remains a fundamental problem in science education at the junior high school level, mainly because teacher-centered learning causes students to merely memorize without understanding the concepts. This condition requires the application of a learning model that can foster deep conceptual understanding and reflective awareness through discovery and direct experience. This study used a quantitative approach with a One Group Pretest–Posttest design to measure the effectiveness of applying the Discovery Learning model with a Deep Learning approach. The research subjects consisted of 32 seventh-grade students at SMP Negeri 10 Kupang in the odd semester of the 2025/2026 academic year. Data were collected through learning outcome tests (pretest and posttest), observations of learning implementation, and student reflection sheets. Data analysis was performed using descriptive statistics, including calculations of mean, median, mode, standard deviation, and Normalized Gain (N-Gain) to assess the increase in conceptual understanding. The students' pretest average score of 54.22 increased to 78.09 on the posttest, with an increase of 23.87 points and an average N-Gain score of 0.51 (moderate category). This shows that Discovery Learning-based learning is effective in improving students' conceptual understanding of the relationship between particles and changes in the form of matter. The results of student reflections showed 83.1% positive responses, with the highest aspect being “Impressions and Messages about Learning” (90.6%), indicating that students felt that learning became more enjoyable, interactive, and meaningful. The Discovery Learning model with a Deep Learning approach has proven effective in improving students' conceptual understanding and reflective awareness of Matter States and Particle Models. This approach is recommended for implementation in science learning based on the Merdeka Curriculum to foster critical, reflective learners with scientific character.

2026-01-14T08:43:09+07:00

Penelitian ini bertujuan menganalisis interelasi antara konteks sosial-historis dengan kandungan Tafsir Faid al-Rahman fi Tarjamah Tafsir Kalam Malik al-Dayyan karya K.H. Muhammad Sholeh bin Umar al-Samarani (K.H. Sholeh Darat). Ditulis pada akhir abad ke-19 di tengah ketegangan kolonial Belanda, eksploitasi ekonomi, dan pengawasan ketat pemerintah, tafsir ini diposisikan sebagai respons intelektual dan perlawanan kultural. Menggunakan pendekatan Sosiologi Pengetahuan (Karl Mannheim), penelitian ini mengkaji bagaimana latar belakang anti-kolonial K.H. Sholeh Darat, pengalaman Perang Jawa, dan interaksinya dengan tokoh pencerah seperti R.A. Kartini, secara sadar memengaruhi corak penafsiran. Hasil penelitian menunjukkan bahwa keputusan mufasir menggunakan aksara Pegon dan menonjolkan corak akhlak-sufistik adalah strategi cerdas untuk: 1) Memperkuat identitas keislaman dan nasionalisme (konsep hubbul wathan); 2) Menyediakan bimbingan moral dan spiritual di tengah penindasan; dan 3) Memperluas akses literasi Al-Qur'an bagi masyarakat awam dan perempuan Jawa. Dengan demikian, Faid al-Rahman tidak hanya berfungsi sebagai teks keagamaan, tetapi juga sebagai dokumen sosio-historis yang berperan vital dalam membangun moralitas dan otonomi intelektual Muslim Nusantara, menjadikannya cerminan ideologi yang terlahir dari posisi sejarahnya

2026-02-02T22:31:31+07:00

Mathematical prior knowledge is a crucial foundation for students’ success in learning mathematics at the tertiary level. This study aims to map the prior mathematical abilities of students in the Mathematics Education Study Program based on Newman Error Analysis (NEA) and to identify the dominant types of errors that occur across various basic mathematics topics. The research employed a descriptive quantitative method with 16 first-semester students as participants. The instrument used was a prior mathematics ability test covering social arithmetic, algebra, geometry, circles, trigonometry, functions, and calculus. Data analysis was conducted in two stages: descriptive quantitative analysis to determine students’ levels of achievement, and NEA-based error analysis to classify errors into five categories, namely reading errors, comprehension errors, transformation errors, process skills errors, and encoding errors. The results show that students’ average achievement varied across topics, with the highest performance in social arithmetic (95.83%) and the lowest in functions (53.13%). The dominant errors identified were transformation errors and process skills errors, particularly in algebra, geometry, trigonometry, and functions. These findings confirm that NEA is an effective diagnostic tool for identifying students’ cognitive barriers in mathematical problem solving and provides a basis for designing more adaptive and conceptually oriented instructional strategies.
