Teaching Practice Research Of High School Chemistry Myth Concept Transform

"2017 National Higher Education Entrance Examination Outline" revision of chemistry,chemistry focus on training the core of literacy.To comply with the new requirements of the revised syllabus,teachers should focus on training students the ability to discipline in the classroom,which is the basis for learning chemistry concepts to improve students' literacy core chemistry.The study found that before and after the classroom teaching,It does not have much effect on the change of the individual concept of many students.This fully reflects the inefficiency and blindness of the teaching of scientific concepts.This study applied a new teaching model of concept change to teaching,and found that the new teaching model has better teaching effect than the traditional teaching model.There are many teaching strategies for conceptual change.In practical teaching,choosing appropriate teaching strategies is the key to good teaching results.Based on its own teaching practice,this study chooses the teaching practices of conceptual transformations of two typical examples of "material quantity" and "redox reaction" in the textbooks of the Chemistry PEP for Senior High School in PEP,The reference role.Theoretically,the research deeply studies and summarizes the research background,the purpose and significance of the research on the conceptual transformation theory system,and at the same time explains and summarizes the basic concepts involved such as scientific concepts,mythological concepts and concept transformation.After studying and thinking deeply about the system of conceptual change,this article summarizes and elaborates its connotation,theoretical basis and teaching strategies.In practice,this research takes psychology and modern pedagogy as the perspectives,examines the concept of chemical myth based on the theories of cognitive development,constructivism and concept transformation,Select the "amount of substance" and "redox reaction" These two compulsory high school stage a relatively large degree of difficulty the two concepts were studied.In the study,many research methods such as investigation and questionnaire,interviews,comparative analysis and statistical research were used to probe into the students' myths and concepts.According to the concept of myths students exist,targeted and scientific teaching design,the concept of teaching students to change,and achieved some research results.Finally,on the basis of practical research,it is concluded that the teaching of concept change can achieve better teaching effect than the traditional teaching mode,and can be practiced.According to the survey of students' cognition and emotion,students are willing Accept the concept of change teaching mode,high recognition,promotion of great value.
