Abstract

In the digital era, students still face difficulties in understanding abstract physics concepts such as Ohm's Law and resistance, primarily due to conventional, teacher-centered instructional methods. This study aims to investigate the integration of the Higher-Order Thinking Laboratory (HOT-Lab) method with PhET virtual simulations to improve students’ higher-order thinking skills (HOTS) in learning about conductor resistance. Using an experimental method, students conducted virtual practicum activities via the PhET Interactive Simulations platform, specifically utilizing the "DC Circuit Construction Kit." The learning process followed structured HOT-Lab phases: identifying problems, hypothesis formulation, experimentation, data analysis, and result communication. Results showed a strong linear correlation (R² = 0.9999) between voltage and electric current, indicating that incandescent lamps can function as resistors under certain conditions, consistent with Ohm’s Law. Regression analysis further validated this with a model  ????=0.0554????+0.0021, and students demonstrated improved conceptual understanding and analytical reasoning. The integration of HOT-Lab with virtual labs is applicable in remote or resource-limited learning environments, promoting active, reflective, and student-centered learning aligned with 21st-century skills.

Abstract

Technological advancement requires physics learning to integrate media that support students’ problem-solving skills. However, physics instruction at Madrasah Aliyah Negeri 2 Subang Regency has not optimally developed this competency. A diagnostic test of 30 eleventh-grade science students showed an average problem-solving score of 43.5, below the Minimum Mastery Criterion of 70, with the lowest performance in the mathematical procedure indicator (31.8). Needs analysis revealed that 57.7% of students considered teaching materials unhelpful, 80% preferred interactive, visual, story-based media, and 92.6% had never experienced comic-based physics learning. Therefore, this study aimed to develop and assess the feasibility of KODI-Web, a web-based learning medium integrating digital comics with the Higher Order Thinking Laboratory (HOT-Lab) model for momentum and impulse learning. The study employed a Research and Development approach with a convergent mixed-methods design based on the 4-D model: Define, Design, Develop, and Disseminate. Feasibility was evaluated by three validators—a media expert, subject expert, and physics teacher—using Aiken’s V index. The results showed Aiken’s V of 0.88 for material and media feasibility, categorized as “very valid,” while the highest score was obtained for the contextual aspect (0.94). These findings indicate that KODI-Web is feasible in content, design, and functionality. Nevertheless, the study only covered development and feasibility assessment and did not examine its impact on problem-solving abilities. Further experimental or quasi-experimental research with larger samples is recommended to determine its effectiveness.
