Mathematics is one of the fundamental subjects for engineering students. While learning mathematics, students often find it difficult or lose interest due to the complexity of the subject. Augmented reality (AR) could aid students to learn certain concepts or theories that were difficult to understand in the classroom and also has the capability to enhance the instructional/learning material. In this study, an AR-based learning setting named geometry learning assistant (GLA) was developed to teach geometry to students in a mathematics course. GLA provides an interactive and immersive experience to the students that helped them to learn about 3D vectors and direction ratios. The application includes vector addition, cross product, position vector, direction ratios, and dot product with real-time examples for better learning. Experimental research was organized to investigate the impact of AR intervention on learner's memory retention abilities and learning. Eighty 1st-year polytechnic students participated in the study and they were divided randomly into two groups: experimental group (N = 40) and control group (N = 40). Students of the experimental group were made to learn using AR-based GLA, whereas the students from the control group were treated using interactive simulation (IS). The experimental results showed that the learners from the experimental group have better memory retention abilities after 2 and 4 weeks of the learning activity. AR-based GLA provided a 3D immersive learning experience to the students that enhanced their visualization of the core concepts, which additionally improved their memory retention abilities.

测量基于增强现实的几何学习助手对学生 3D 几何记忆保持能力的有效性

数学是工科学生的基础学科之一。在学习数学的过程中，学生往往会因为学科的复杂性而感到困难或失去兴趣。增强现实 (AR) 可以帮助学生学习某些在课堂上难以理解的概念或理论，并且还具有增强教学/学习材料的能力。在这项研究中，开发了一种名为几何学习助手 (GLA) 的基于 AR 的学习环境，用于在数学课程中向学生教授几何。GLA 为学生提供交互式和身临其境的体验，帮助他们了解 3D 矢量和方向比。该应用程序包括向量加法、叉积、位置向量、方向比和点积，并带有实时示例以更好地学习。组织了实验研究来调查 AR 干预对学习者记忆保持能力和学习的影响。80 名理工科一年级学生参加了研究，他们被随机分为两组：实验组（N  = 40）和对照组（N  = 40）。实验组的学生使用基于 AR 的 GLA 进行学习，而对照组的学生使用交互式模拟 (IS)。实验结果表明，实验组的学习者在学习活动进行2周和4周后，记忆保持能力更强。基于 AR 的 GLA 为学生提供了 3D 沉浸式学习体验，增强了他们对核心概念的可视化，进一步提高了他们的记忆保持能力。
