Abstract The main value of understanding of chemistry subject to teachers' teaching lies in condensing the original problems of learning subjects, extracting the perspective, developing the cognitive thinking and constructing the hierarchical structure of theme concept. The perspective determines the development of the way of thinking and the degree of problem original, which has important value of subject epistemology. This study explores how the cognitive perspective is extracted and developed from the perspective of disciplinary understanding, taking the theme of organic molecular composition and structure as an example. Tracing the original thought of chemists and analyzing the disciplinary function of concepts is the primary link to extract the perspective; secondly, based on the perspective of discipline function, we can experience the development of perspective vertically; enrich the cognitive perspective based on contradictions and conflicts, and realize the multifaceted perspective horizontally; finally, develop a structured and original understanding based on the perspective.
