Abstract

The low critical-thinking ability of elementary school students and the limitations of teaching materials in visualizing the concept of photosynthesis pose challenges to learning science. This study aims to analyze the development needs, determine the feasibility, and test the effectiveness of DELBARA (Deep Learning Based on Augmented Reality) teaching materials on photosynthetic materials to improve the critical thinking skills of Grade IV elementary school students in Jepara Regency. The research uses the Research and Development (R&D) method with the ADDIE model, which includes the Analysis, Design, Development, Implementation, and Evaluation stages. Data were collected through observation, interviews, questionnaires, tests, and documentation, then analyzed descriptively and using the Normalized Gain (N-Gain) test. The results of the study show that teachers need interactive, innovative teaching materials that can visualize abstract concepts. DELBARA's teaching materials are deemed feasible following validation by material and media experts, who assessed the content, presentation, language, graphics, and Augmented Reality integration. The product implementation showed an increase in critical thinking skills, with a pretest average of 71.22 rising to 86.00 on the posttest and an N-Gain of 0.513, placing it in the medium category.
