Augmented Reality (AR) has the potential to improve Problem-Based Learning (PBL) in higher education by easing the visualisation of difficult biological ideas and encouraging active participation. The purpose of this study was to assess the viability and content validity of AR-integrated teaching resources created for PBL. The study concentrated on the validation stage using the ADDIE development paradigm and included three expert validators in instructional design, educational technology, and biology education. Aiken's V was used to evaluate content validity in terms of language appropriateness, presentation viability, and topic feasibility. To enhance the teaching materials, qualitative input from validators was also examined. The findings showed strong validity across all dimensions, with Aiken's V values more than 0.85. The display of AR elements, the clarity of instructions, and the alignment of learning exercises with problem-solving objectives were the main areas of expert recommendation. The quality and usability of the updated materials were improved by incorporating these suggestions. All things considered, the AR-integrated teaching resources showed excellent content validity and viability for postsecondary education. According to the results, the products are appropriate for use in classrooms and can help students grasp difficult biological ideas through interactive, technologically enhanced learning opportunities.

This study aimed to develop and evaluate a Problem-Based Learning (PBL)-based science e-module integrating the local wisdom of Ledre to foster junior high school students' critical thinking skills on the topic of food additives. The study employed a Research and Development (R&D) approach using the 4D model consisting of the Define, Design, Develop, and Disseminate stages. The developed product was evaluated in terms of its validity, practicality, and effectiveness. Product validity was assessed by subject-matter experts, instructional media experts, and science education practitioners using Aiken's V. Practicality was evaluated through learning implementation observations, teacher and student response questionnaires, and readability analysis. Effectiveness was determined using a one-group pretest-posttest design involving 64 eighth-grade students from two classes receiving the same instructional treatment. Students' critical thinking skills were analyzed using the Normalized Gain (N-Gain) and the Wilcoxon Signed-Rank Test. The developed science e-module achieved an average Aiken's V coefficient of 0.93, indicating high validity, while the assessment instrument demonstrated good reliability (Cronbach's Alpha = 0.815). Practicality evaluation showed highly positive implementation and user responses, indicating that the e-module was feasible for classroom application. Students' critical thinking skills improved from a mean pretest score of 43.55 to a mean posttest score of 83.73, with an average N-Gain score of 0.6965 (moderate category). The Wilcoxon Signed-Rank Test confirmed a statistically significant improvement (p < 0.001), accompanied by a very large effect size (r = 0.87). These findings demonstrate that integrating Ledre local wisdom into the Problem-Based Learning framework provides an effective digital learning resource for fostering contextual science learning and enhancing junior high school students' critical thinking skills.
