    The study investigated the effect of problem-based learning (PBL) with augmented reality (AR) on problem-solving and computational thinking (CT) skills, along with students’ satisfaction with AR in mathematics learning. Ninety eighth-grade students participated in a quasi-experiment with three groups: experimental (PBL with AR and standard PBL) and control (conventional learning) groups, each with thirty students. The geometry learning using augmented reality experience (GLARE) application covered 3D geometry, including cubes, cuboids, prisms, pyramids, cones, cylinders, and spheres. MANOVA was used to examine the problem-solving and CT skills, while the satisfaction was evaluated as percentages. The findings demonstrated all groups improved significantly in CT and problem-solving (p < 0.05), with the PBL+AR group achieving the highest improvement. Most students found AR engaging, motivating, and effective for understanding complex geometry concepts. They also appreciated its ease of use and support for independent learning. However, some encountered technical problems, such as device incompatibility and poor internet connectivity.

    This research aimed to synthesize a review of the literature and theory to develop a flipped classroom (FC) learning model to enhance 1st-year bachelor's degree Thai student-teacher academic achievement (AA) and problem-solving skills (PSS). The sample consisted of 90 student teachers enrolled in the Digital Media and Learning Innovation (DMLI) course in the Elementary Education Program in the Education and Liberal Arts Faculty at a private university in southern Thailand's Songkhla Province. The study used the FC model in an experimental group (S2) (n=30) while simultaneously comparing it to the control (S1) group using traditional classroom methods (n=31) and another group (S3) using problem-based learning (PBL) (n=29). Nine academic experts reviewed the FC's model development. The quasi-experiment took place over four weeks in March and April 2021. All instruments were evaluated by an additional five academic experts whose input evaluation was analyzed using MANOVA statistics with IBM's<sup>®</sup> SPSS<sup>®</sup> for Windows Version 21 program. The results showed that Flipped PARSER group (S2) had AA results significantly higher than both the traditional and PBL groups. Also, S2's results concerning their PSS were significantly higher than S1 and S3, while their student-teacher satisfaction was also at the highest level. These results showed that the proposed Flipped PARSER Model excels at promoting the development of undergraduate students' motivation, academic achievement, and PSS.
