Abstract

This study aims to examine the effectiveness of the Problem-Based Learning (PBL) model assisted by Augmented Reality (AR) technology regarding the respiratory system in improving students’ critical thinking skills and learning motivation. The research method used was a quasi-experimental design with a one-group pretest-posttest model. The subjects were 30 eleventh-grade students from a public high school in Garut City. Research instruments included a critical thinking test and a learning motivation questionnaire. The results showed a significant improvement in students’ critical thinking scores after the implementation of PBL with AR support. Additionally, learning motivation data analyzed from 16 statement items revealed an average score of 76.36%, which falls into the high category. Each indicator of learning motivation also showed positive outcomes, with the highest score on the meaningfulness indicator at 81% and the lowest on the attention indicator at 70%. These findings indicate that the implementation of PBL assisted by AR enhances students' critical thinking and promotes overall learning motivation. Therefore, innovative instruction that integrates AR technology can serve as an effective alternative in biology education, particularly for abstract topics such as the respiratory system
