Research On The Conceptual Transformation Of Chemical Myth In Senior High School Based On Dissipative Structure Theory

Oxidation-reduction reaction is recognized as a difficult point in middle school chemistry teaching,but in teaching,teachers find that it is difficult for students to grasp the knowledge point accurately.What they learn is only one-sided knowledge,which leads to the concept of mystification.The existence of the misconception will make it difficult for students to follow up their study.Therefore,it is of great significance to study the change of students' misconception.Under the guidance of dissipative structure theory,this paper tries to understand the characteristics and reasons of misconception through the current research on the transformation teaching of misconception,which is based on the theory of dissipative structure.Furthermore,this paper explores the misconception about oxidation-reduction reaction in senior high school students,and makes an empirical study on the teaching method of the transformation of misconception.This paper is mainly composed of the following five parts:The first part is the introduction.This paper mainly describes the background,purpose and significance of this topic,research methods and design ideas.The second part is literature review.The status quo of the research on the concept of myth at home and abroad as well as the core concepts related to the topic of the thesis are listed,which lays a foundation for the practical research on the transformation of the concept of myth in the future.The third part is the theoretical basis of the study.It includes dissipative structure theory,constructivism learning theory and Piaget's cognitive development theory.The fourth part is the pre-test and analysis of the study.Firstly,the content of oxidation-reduction reaction is analyzed,then the concept of pre-school myth is explored and the teacher interview is carried out.Finally,the results are integrated with the concept of post-school myth,and the origin of students' myth concept is analyzed.The fifth part is empirical research.Design the method and strategy of conceptual transformation of mystification.On the basis of the previous research,teaching design and practical research are carried out.Finally,draw a conclusion and summarize reflection.
