Abstract

This study explores the implementation of Merdeka Curriculum through the Technological Pedagogical and Content Knowledge (TPACK) approach to improve senior high school students' conceptual understanding of momentum and impulse. Merdeka Curriculum emphasizes innovative and flexible learning, but its practical application in improving students' conceptual knowledge, especially in physics, remains unexplored. thus highlighting the need for teaching strategies that integrate technology, pedagogy, and content effectively. This research was conducted at SMA Nurul Iman Tanjung Morawa with class XI MIA 1 as the experimental group and XI MIA 2 as the control group. A quasi-experimental design with non-equivalent control groups was used, where the experimental group received instruction using the TPACK approach, while the control group followed conventional teaching methods. Data analysis using SPSS version 25 showed that the experimental group achieved a mean score of 71.42 (71%), compared to 62.29 (62%) for the control group. These results indicate that the implementation of TPACK-based curriculum is effective in improving students' conceptual understanding. Statistical analysis yielded a significance value of 0.037 (<0.05), which confirmed the success of the approach. Thus, this study concludes that the implementation of the TPACK-based Merdeka Curriculum effectively improves senior high school students' conceptual understanding of momentum and impulse.

Abstract

This research investigates the Qur'anic perspective on physics, specifically focusing on measurement. Employing a qualitative library research methodology, this study integrates an analysis of Qur'anic exegesis. Qur'anic interpretations are utilized to understand the meaning of relevant verses, particularly Surah Al-Qamar (54:49) and Al-Furqan (25:2), and their connection to the concept of measurement in physics. As a library-based study, the primary data sources consist of written materials such as books, journals, tafsir (exegesis) texts, and other documented sources. Secondary data includes Hadith, further interpretive works, physics textbooks, and other pertinent literature. Measurement is defined as the process of comparing a measured quantity with another quantity of a predetermined scale and unit. Measurement has varying applications across different educational levels. In elementary and middle schools, measurement is taught as a topic within science and physics. At the university level, measurement serves as a fundamental course used to prove or test concepts, principles, and facts. The actualization of physics in measurement, based on the Qur'an and Sunnah, can foster attitudes of honesty and carefulness in comparing values in every activity. If measurement is conducted without the guidance of the Qur'an and Sunnah, inconsistencies between theory and fact may arise. Individuals who habitually measure according to Qur'anic and Sunnah concepts will find that their activities and their products align with reality, as dishonesty and negligence are strictly avoided.

Abstract

This study aims to examine how Islamic values are integrated into chemistry learning through a contextual approach at the Chemistry Education Study Program of Universitas Islam Sumatera Utara. Using a qualitative case study method, data were collected through interviews, classroom observations, and document analysis involving lecturers, students, and program administrators. The analysis focuses on how religious values are embedded within the learning process. Integration occurs through various strategies, including the use of instructional materials that reference Quranic verses and hadiths, contextual case studies with real-life relevance, group-based reflections, and character-oriented assessments. A contextual learning approach—particularly problem-based learning and the use of Islamic-themed teaching media—is employed to bridge scientific concepts with students’ religious and everyday experiences. Findings indicate that this model encourages student engagement and supports the internalization of values such as honesty, social responsibility, and care for the environment. The integration of Islamic values is not merely additive but becomes an integral part of students’ cognitive and affective learning experiences. This study contributes to the discourse on faith-based education by offering a model for combining religious and scientific knowledge in higher education. It underscores the potential of contextual learning to foster both academic understanding and character development, in line with Indonesia’s educational vision that promotes intellectual achievement alongside moral and spiritual formation.
