Construction Of Chemistry Core Concepts Of Senior High School Students Based On Problem-solving Theory

Chemistry is an important discipline in natural science.The study on chemistry of high school students is not only the learning of knowledge,but also the improvement of their own accomplishment.In this process,the core concept of chemistry formed by middle school students can lay a good foundation for students' life long learning.Since the curriculum reform,more and more attention has been paid to the construction of students' core concept of chemistry.Therefore,the teaching mode of concept construction are put forwarded.The core problem of concept construction teaching model is the solution of driving problem.The research of problem solving theory has reached a very high level.However,the research on how to apply problem-solving theory to conceptual construction mode is relatively scarce.The purpose of this paper is to deepen the training of discipline core literacy in curriculum reform,and to study the construction of core concept in chemistry course of high school students.Through the design and solution of driving problems,the author improves the students' core concept of chemistry under the mode of concept construction.The study combined information processing theory with constructivism can solve the problem of "drive" in the mode of concept construction.The design and solution of the problem can provide reference for teaching research.The consists of five parts:In the first part,an overview of the background,purpose and significance research,the current situation at home and abroad,the research content and research methods are reviewed.In the second part,the definition and theoretical basis of the related concepts of problem solving theory and chemical core concepts are redefined.After consulting a lot of information and literature,the concept of problem solving and the influencing factors of problem solving are discussed.The contents of each concept in the core concept of chemistry and the characteristics of the core concept of chemistry are analyzed.In the third part,the core concept level of high school students are studied by the questionnaire survey.And the data analysis and result of survey are gained.In the fourth part,based on the problem-solving theory,the problem-driven problem in the concept-building model are designed and solved.In the fifth part,the case analysis of the concept construction model,and the analysis of the test data and the results of the relative contents of the experimental class and the control class are gained.Summary and prospect of the research are put forward in the end.
