Abstract

Critical thinking skills are essential competencies in 21st-century physics education. However, previous studies indicate that students’ critical thinking abilities remain relatively low due to teacher-centered instructional practices and limited exploratory learning experiences. This article aims to systematically review the effectiveness of implementing virtual laboratory-based problem-solving scenarios in improving students’ critical thinking skills, particularly in Ohm’s Law material. The study employed a literature review method by analyzing relevant national and international journal articles published within the last ten years. The selected articles met criteria related to topic relevance, research methodology, and examined variables. The findings reveal that the integration of virtual laboratories and problem-solving approaches consistently contributes to improving students’ analytical skills, evaluation abilities, logical reasoning, and conclusion drawing. Interactive simulations and structured problem-solving stages enhance students’ active engagement and higher-order thinking skills. Therefore, virtual laboratory-based problem-solving scenarios are recommended as an innovative instructional strategy in physics learning.

Abstract

This study aims to examine the integration of digital teaching materials based on Project-Based Learning (PjBL) combined with the STEM approach in high school physics learning. The method used is a qualitative literature review by analyzing 16 national and international journal articles published between 2015 and 2024, which were selected based on relevance to the topic, methodological clarity, and the presence of empirical. The results indicate that digital teaching materials enhance the quality of learning through interactive, flexible, and contextual content delivery. The implementation of the PjBL model promotes active student engagement, improves collaboration skills, and facilitates the application of physics concepts in real-life contexts. Meanwhile, the STEM approach contributes to the development of critical thinking, creativity, and problem-solving skills. The integration of digital teaching materials, PjBL, and STEM is proven to be more effective than their separate implementation, as it connects theory and practice comprehensively. However, its implementation still faces challenges such as limited technological facilities and user readiness. Therefore, well-designed instructional planning and institutional support are required to optimize its implementation in improving the quality of physics learning.
