Abstract

Conceptual skills in physics are an essential foundation for students to understand natural phenomena deeply and analytically, yet conventional teaching often fails to connect abstract theory with real-life contexts. This study aims to develop a physics learning module integrated with the local wisdom of the Toba Batak Taganing on mechanical wave material to enhance students' conceptual skills. The developed module links concepts of waves, resonance, and interference with the acoustic principles of the Taganing musical instrument through a Problem-Based Learning approach. Expert validation results demonstrated a high level of feasibility, with details of 78% (Feasible category) by subject matter experts, 85% (Highly Feasible) by cultural experts, and 97% (Highly Feasible) by language experts. A limited trial with grade XI students showed an improvement in conceptual skills, specifically an abstraction ability of 71% (Good) and systematic thinking of 72% (Good). Teacher and student responses to the module were very positive, with a practicality level of 81%, indicating that the module is not only easy to use but also contextual and engaging. These findings confirm that integrating local wisdom into ethnoscience-based physics learning design is not only effective in strengthening students' conceptual understanding but also plays a strategic role in preserving cultural heritage and fostering learning engagement.

Abstract

This research aims to determine the effect of the Kahoot-assisted guided inquiry model to improve high school students' learning outcomes in class X renewable energy material at SMA Parulian 2 Medan. The method used is quasi-experimental with a nonequivalent control group design. Sampling was carried out using purposive sampling technique. The research samples for experimental class X-B and control class X-A each consisted of 28 students. The instrument used is a learning outcomes test, multiple choice with 20 questions. Before being given treatment, a prerequisite test must be carried out to determine whether the sample comes from a population that is normally distributed and homogeneous. Furthermore, the pretest was given to the experimental and control classes with average scores of 52.85 and 51.78 respectively with standard deviations of 16.36 and 13.69. After being given treatment in the experimental and control classes, by giving a posttest an average score of 65.53 and 66.42 was obtained with a standard deviation of 12.57 and 10.35. To determine the differences between the two classes, a one-sided t-test was carried out with α=0.05, it was found that t-hitung > t-tabel, which indicated that there was a significant difference in science process skills in Newton's law material.

Abstract

This study aims to implement an Internet of Things (IoT) and multifunctional sensor system in the electromagnetic induction practicum to enhance students’ conceptual understanding and analytical skills. The research employed a quasi-experimental design with pre-test and post-test models involving 26 students enrolled in the Physics Laboratory Design and Production course. The practicum utilized real-time data acquisition, allowing students to directly observe relationships among magnetic flux variations, induced electromotive force (EMF), and current direction through a digital interface. Results revealed a significant increase in students’ conceptual understanding, with mean scores rising from 59.8% to 81.6% (p < 0.001). Moreover, 84.7% of participants achieved Good to Very Good understanding levels. Questionnaire data indicated high levels of motivation and satisfaction with the IoT integration, particularly regarding interactivity, rapid data analysis, and real-time visualization of physical phenomena. The implementation of IoT and multifunction sensors effectively improved the quality of physics laboratory learning, strengthened analytical thinking skills, and fostered contextual, technology-oriented learning experiences relevant to modern scientific education.
