掌握有机化学中使用的分子的许多不同的图解表示对学生来说是具有挑战性的。本文总结了最近的研究表明，操纵三维分子模型可以促进对这些表示的理解和使用。结果表明，当学生有模型可用时，他们在图表之间的翻译更成功，使用模型来制定世界中的翻译过程是对学习的预测，并且使用模型作为反馈（检查图表翻译的准确性）特别有效。基于模型的反馈优于单独的口头反馈，模型支撑学习而不是充当拐杖，基于模型的教学在几天的延迟中具有弹性，并且当模型不再可用时，使用模型的学习转移到性能上。最后，在研究情境中，虚拟模型与手持模型在促进学习方面具有同等作用。
Mastering the many different diagrammatic representations of molecules used in organic chemistry is challenging for students. This article summarizes recent research showing that manipulating 3-D molecular models can facilitate the understanding and use of these representations. Results indicate that students are more successful in translating between diagrams when they have models available, that using a model to enact the translation process in the world is predictive of learning, and that using models as feedback (to check the accuracy of diagram translation) is particularly effective. Model-based feedback is superior to verbal feedback alone, models scaffold learning rather than act as a crutch, learning with model-based instruction is resilient over a delay of several days, and learning with models transfers to performance when models are no longer available. Finally, virtual models are equivalent to hand-held models in promoting learning in the studied contexts.
