Evaluating Augmented Reality Tools to Enhance Science Concept Comprehension in High Schools

Thesis Abstract

The effectiveness of science education in high schools remains critically dependent on students’ comprehension of complex scientific concepts, which are often hindered by traditional teaching methodologies that lack interactive and immersive elements. This study investigates the potential of augmented reality (AR) tools to enhance science concept understanding among high school students, addressing the persistent challenge of engaging students and improving learning outcomes in science curricula. The primary aim is to evaluate the impact of AR-assisted instruction on students' comprehension, engagement, and retention of scientific concepts, with specific objectives to compare the achievement levels of students exposed to AR-enhanced lessons with those receiving conventional instruction, and to examine students’ perceptions of the effectiveness of AR tools in facilitating learning. Adopting a quasi-experimental research design within a pedagogical framework grounded on constructivist learning theory and the technological acceptance model, the study was conducted in three public high schools with a total population of 450 science students across Grades 10 and 11. A total sample of 180 students was selected through stratified random sampling, evenly divided into experimental and control groups. The experimental group engaged with augmented reality applications—specifically designed 3D interactive modules for physics and biology—while the control group received standard classroom instruction without AR integration. Data collection was carried out using structured achievement tests aligned with curriculum standards, validated instruments for measuring engagement and motivation, and semi-structured questionnaires for capturing perceptions of AR effectiveness. Validity and reliability of the instruments were established through pilot testing and expert validation, achieving a Cronbach’s alpha of 0.87. Data analysis involved descriptive statistics to characterize the sample, followed by inferential techniques including independent t-tests to compare achievement scores, multivariate analysis of covariance (MANCOVA) controlling for prior knowledge, and thematic analysis to interpret qualitative responses regarding student perceptions. The study hypothesizes that students exposed to AR tools will demonstrate significantly higher comprehension, engagement, and retention levels compared to their peers in traditional settings. Anticipated findings suggest that the integration of AR technology will lead to statistically significant improvements in students’ science concept mastery, as evidenced by higher post-test scores in the experimental group (p < 0.05). Additionally, students are expected to report increased motivation, interest, and perceived understanding of concepts when interacting with AR applications. The findings will corroborate theoretical assertions from constructivist and technology acceptance perspectives, emphasizing that immersive, interactive visualizations foster deeper comprehension and positive attitudes toward science learning. This research makes a notable contribution to the field of science education by empirically validating the pedagogical value of augmented reality, thereby providing evidence-based implications for curriculum developers, educators, and policymakers aiming to leverage emerging technologies for enhanced science instruction. It extends theoretical understanding of how AR influences cognitive and motivational dimensions of learning and offers practical insights into effective implementation strategies. In conclusion, the study recommends the systematic integration of AR tools into science curricula to facilitate active, inquiry-based learning. It advocates for professional development programs to equip teachers with requisite skills for AR deployment and suggests further research to explore longitudinal impacts and scalability across diverse educational contexts. Overall, the study affirms that augmented reality has the potential to revolutionize science education, making concepts more accessible, engaging, and comprehensible for high school students.
