Abstract

Background: Students often find curved-sided geometric shapes difficult to grasp because the material is usually introduced in a highly symbolic way. This condition creates a clear need for learning materials that can present ideas more visually and in contexts that feel relevant to students. Aim: The study seeks to design and examine a learning module that blends Augmented Reality with the principles of Realistic Mathematics Education to support stronger conceptual understanding. Method: Using a Research and Development approach, the study followed the ADDIE sequence from early analysis to final evaluation. The module was reviewed by subject and media experts, tested in a small group to gauge usability, and later implemented in larger classes. Its effectiveness was assessed by comparing posttest scores from a class using the AR–RME module and another class taught with standard materials. Results: Expert feedback showed that both the content and media components reached valid to very valid levels. Students and teachers also reported that the module was easy to use and fit well within classroom activities. The experimental class recorded higher posttest scores than the control group, indicating meaningful gains in conceptual understanding. Conclusion: Augmented Reality, when embedded in a Realistic Mathematics Education setting, offers a learning experience that helps students connect abstract geometric ideas with clearer mental models. The module developed in this study meets the criteria for validity, practicality, and effectiveness, and can serve as a valuable learning resource for geometry instruction.

Abstract

Academic writing is a core competency in higher education, yet many university students continue to struggle with constructing coherent arguments, synthesizing evidence, and regulating the writing process. Although Guided Inquiry Learning (GIL), metacognitive strategies, and Learning Management Systems (LMSs) have each demonstrated educational benefits, limited research has examined their integrated use to support academic writing. This study investigated the effectiveness of integrating GIL, metacognitive strategies, and LMS support to enhance students’ academic writing skills. A quasi-experimental pretest–posttest control group design was conducted with 120 sixth-semester undergraduate students from two Indonesian universities. Students’ academic writing performance was assessed before and after the intervention using a standardized writing assessment. The findings showed that both groups had comparable initial writing abilities. After the intervention, students who experienced the integrated instructional approach demonstrated substantially greater improvement in academic writing than those receiving conventional instruction. The integration of inquiry-based learning, metacognitive regulation, and LMS-supported learning promoted more structured writing, reflective learning processes, and stronger academic argumentation. These findings highlight the value of an integrated pedagogical framework for strengthening academic writing instruction in higher education.
