The study aimed to develop a Problem-Based Learning (PBL) model integrated with augmented reality (AR) and to analyze teachers' perceptions of using the AR application for teaching mathematics. This research followed a Research and Development (R&D) design to develop and validate the PBL model using an AR application. The model was evaluated by five experts and tested by fifty secondary school teachers. Data was collected using a 5-point Likert scale for expert evaluation and teacher perception scales. According to the expert review, the model, learning content, and AR application were implementable, with a mean score of 4.28 (SD = 0.55). Experts noted that the PBL-based lesson plan provided a comprehensive overview of the learning process and clearly outlined the steps for using the model. It was well-organized, easy to follow, and facilitated active learning. They also found that the learning content was consistent with the learning objectives, and the PBL activities were clearly explained and relevant to the material. The illustrations in the learning materials were relatable to everyday life. Additionally, based on teacher perceptions, the total mean score was 4.43 (SD = 0.59), indicating that teachers provided positive feedback on using the GLARE application for teaching. Over 90% of the teachers agreed it would create a joyful, fun, and interesting learning environment and help teach geometry topics. However, some teachers were unsure if GLARE would simplify teaching, enhance effectiveness, or promote student self-learning. They were also uncertain about using GLARE regularly in their teaching or recommending it to colleagues.
