Abstract

Critical thinking skills are essential competencies that elementary school students need to develop in order to meet the demands of 21st-century learning. However, science instruction is still frequently dominated by conventional teaching approaches, limiting students’ opportunities to actively engage in higher-order thinking. Furthermore, studies integrating Project-Based Learning (PjBL) with Sketchfab Web 3D Augmented Reality (AR) to enhance elementary students’ critical thinking skills remain limited. Sketchfab Web 3D AR enables students to interact with three-dimensional science objects through web-based augmented reality, providing more immersive and accessible learning experiences. This study aimed to examine the effectiveness of PjBL assisted by Sketchfab Web 3D AR in improving fourth-grade students’ critical thinking skills in science learning. A quasi-experimental method with a nonequivalent control group design was employed. The sample consisted of 52 fourth-grade students divided into an experimental class and a control class. Data were collected using a critical thinking skills test and analyzed using descriptive statistics, independent-samples t-tests, effect sizes, and N-Gain analyses. The results revealed a significant difference in critical thinking skills between the experimental and control groups (p < .05). The effect size of 1.189 indicated a large effect, while the N-Gain score of 0.568 was moderate. These findings demonstrate that Project-Based Learning assisted by Sketchfab Web 3D AR is effective in enhancing elementary students’ critical thinking skills.
