在化学领域学习的学生需要将他们的空间技能和概念知识结合起来。然而，由于传统的教学方法不能完全帮助学生理解，模型感知以及对分子空间过程和空间结构的理解一直是学生学习困难的原因。在这项研究中，我们提出了一种技术解决方案，通过自动创建化学结构的二维（2D）表示和三维（3D）分子可视化之间的联系来帮助空间学习过程。获取化学结构的图像并对其进行实时处理，以进行结构识别和三维模型生成。对三维分子模型进行了简化，便于实时交互绘制。通过对一年级大学生的实验，评价了该方案在提高个体空间能力方面的效果。我们对结果的分析表明，虚拟模型和移动应用程序能够缩小不同空间能力水平学生之间的表现差距。
Students undertaking courses in the field of chemistry need to integrate their spatial skills and conceptual knowledge. However, model perception along with the understanding of spatial processes and spatial structures of molecules has been a cause of difficulty for students as conventional teaching methods cannot fully aid student comprehension. In this research, we propose a technological solution to aid the spatial learning process by automatically creating a link between two-dimensional (2D) representations of chemical structures and three-dimensional (3D) molecular visualization. The image of a chemical structure is acquired and processed on-the-fly for structure identification and 3D model generation. The 3D molecular model is simplified for real-time interactive rendering. The efficacy of the proposed solution in enhancing spatial ability of individuals is evaluated through an experiment on first year undergraduate students. Our analysis of the results suggests that virtual models and mobile applications are capable of narrowing the performance gap between students with different levels of spatial ability.
