论文摘要
了解空间转换及其数学表示在计算机辅助设计，机器人技术等中至关重要。这项研究已经开发并测试了增强现实（AR）应用（Brickxar/t），以增强学生对空间转换矩阵的学习。 Brickxar/t利用AR功能，包括信息增强，实物对象相互作用和体现的学习，以创造一种新颖有效的可视化体验。在用户研究中，使用乐高模型将Brickxar T作为一种学习干预评估，以评估学生的学习成就。该研究比较了AR（n = 29）与非AR（n = 30）学习研讨会与有关旋转测试和数学问题的Purdue可视化的测试前和测试。参加两个研讨会的学生在AR研讨会上倾向于表现出更大的进步，学生的数学成绩得到了显着提高。工作室后的调查表明，学生倾向于认为Brickxar/T是一个有趣且有用的应用，他们在AR中学习的时间比非AR的时间更多。
Understanding spatial transformations and their mathematical representations are essential in computer-aided design, robotics, etc. This research has developed and tested an Augmented Reality (AR) application (BRICKxAR/T) to enhance students' learning of spatial transformation matrices. BRICKxAR/T leverages AR features, including information augmentation, physical-virtual object interplay, and embodied learning, to create a novel and effective visualization experience for learning. BRICKxAR T has been evaluated as a learning intervention using LEGO models as example physical and virtual manipulatives in a user study to assess students' learning gains. The study compared AR (N=29) vs. non-AR (N=30) learning workshops with pre- and post-tests on Purdue Visualization of Rotations Test and math questions. Students' math scores significantly improved after participating in both workshops with the AR workshop tending to show greater improvements. The post-workshop survey showed students were inclined to think BRICKxAR/T an interesting and useful application, and they spent more time learning in AR than non-AR.
