中文摘要：
文章通过梳理化学知识内部表征的已有研究,澄清了研究化学认识结构必须秉持的几个重要观点。在此基础上,提出并界定了化学认识结构的情感—表象—认知三要素,并基于文献研究的视角进一步阐述三要素模型的合理性。最后,论文基于实践的视角,利用三要素模型细致地分析了化学学习如何发生、化学学习带来学习者怎样的发展等问题,体现了该模型对化学教学实践的理论指导价值。
英文摘要：
This paper reviews current studies on the representation of chemistry knowledge, and clarifies several views on how to study studentslepistemic structure of chemistry. Students＇epistemic structure of chemis- try is a complex system which consists of the model of affective, image and eoguition5 and we prove the ra- tionality of this model from the perspective of document research. Finally, we analyze how chemistry learning starts and what effect the chemistry learning has on students based on the idea of the above model from the practical perspective, which can embody the theoretical guiding value of this model in practical teaching.
