Investigation of the Effectiveness of Inquiry-Based Learning on Critical Thinking Skills in High School Physics: A Comparative Study Across Urban and Rural Schools

Project Abstract

This study examines how inquiry-based learning (IBL) influences the development of critical thinking skills among high school physics students and compares outcomes across urban and rural school settings. Grounded in constructivist and cognitive apprenticeship theories, the research investigates whether IBL strategies—such as problem-based investigations, guided questioning, collaborative argumentation, and iterative experimentation—enhance students’ ability to analyze, evaluate, and synthesize physical concepts, apply logical reasoning to novel situations, and justify conclusions with evidence. A mixed-methods design was employed, integrating quasi-experimental and qualitative components to capture both measurable gains in critical thinking and the contextual factors that shape instructional effectiveness. The quantitative phase involved three matched pairs of urban and rural physics classrooms, randomly assigned to either an IBL-enhanced instructional condition or a traditional lecture-demonstration control condition over a 12-week unit on electricity and magnetism. Pre- and post-tests included standardized critical thinking instruments adapted for physics reasoning, performance tasks, and concept inventories to triangulate evidence of higher-order thinking. The qualitative phase comprised classroom observations, teacher interviews, student focus groups, and artifact analyses (lab reports, concept maps, and argumentative essays) to illuminate processes of knowledge construction, epistemic framing, and social interaction that mediate learning outcomes. Quantitative analysis employed ANCOVA to control for prior achievement, with effect sizes calculated to ascertain practical significance, while thematic analysis was used for qualitative data to identify recurring patterns related to inquiry practices, student agency, classroom discourse, and cultural relevance. The results indicate that students in the urban and rural IBL conditions demonstrated significantly greater gains in critical thinking performance compared with their peers in traditional instruction, with medium to large effect sizes (Cohen’s d = 0.50–0.78). Notably, urban IBL groups showed more pronounced improvements in data interpretation, hypothesis evaluation, and collaborative argumentation, while rural IBL groups exhibited substantial growth in problem formulation, model-based reasoning, and transfer to novel contexts. Variations in teacher scaffolding, resource availability, and community-supported inquiry opportunities emerged as critical mediators of effectiveness. The study also reveals that explicit emphasis on epistemic justification, reflective discourse, and structured peer feedback enhances students’ metacognitive awareness and self-regulation during complex problem solving. Implications for practice include professional development standards for implementing IBL in diverse contexts, alignment of assessment with inquiry milestones, and the design of scalable, resource-efficient IBL models suitable for both urban and rural schools. The research contributes to the literature on science education by clarifying how context interacts with inquiry-based pedagogy to cultivate critical thinking in physics and offers a framework for future longitudinal investigations.
