Research on the Mental Model of Organic Chemistry Concepts of Chemistry Normal University Students from the Perspective of Senior High School-University Cohesion

The teaching cohesion between secondary school and university has long been a research focus for educators, while studies on how to effectively bridge organic chemistry between these two educational stages remain scarce. Furthermore, the new curriculum standard lists "chemical concepts" as an important component of the core disciplinary competencies that need to be mastered. As future frontline secondary school teachers, normal university students are required to have a deeper grasp of chemical concepts. Based on this, this study combines text analysis with a two-tier paper-and-pencil test to evaluate the mental models of organic chemistry held by normal university students, focusing on various chemical concepts such as the element concept and structure concept. According to the test results, seven types of defective mental models are summarized, and corresponding teaching suggestions are put forward, aiming to lay a solid foundation for normal university students' subsequent chemistry learning and teaching practice.
