为了开发向有机化学学生展示机械思维和弯曲箭头表示法的改进方法，人们付出了很大的努力；然而，这些技术大多数都不是基于研究的。已经进行的少量研究主要集中在理解学生在某一时刻与弯曲箭头相关联的含义。目前的研究使用 Organic Pad（一种基于平板电脑的创新结构绘图程序）来记录我们为了解二年级有机化学学生在该学科学习过程中如何使用机制变化所做的努力。我们的结果揭示了机械策略在学年中的巨大演变，包括很大一部分学生选择在工作中不使用机械惯例。
Much effort has been expended in developing improved methods for presenting mechanistic thinking and the curved-arrow notation to organic chemistry students; however, most of these techniques are not research-based. The little research that has been conducted has mainly focused on understanding the meaning that students associate with the curved-arrows during a single moment in time. The current research uses Organic Pad, an innovative, tablet person computer-based structure drawing program, to document our efforts to understand how second-year-level organic chemistry students' mechanism use changes over their study of the subject. Our results reveal a dramatic evolution of mechanistic strategies during the academic year, including a large proportion of students who elect not to use the mechanistic convention in their work.
