The Research Of Exploration And Teaching Strategies Of Misconception-based On The Chemical Equilibrium

Since 2003,great changes have taken place in basic education of our country because of the new curriculum reform.High school chemistry teaching pay more and more attention to "taking the student as this","starting from the life experience of students",the education idea,textbook writing and teaching strategy strive to reflect it.Students's life experience and cognition match with the zone of proximal development in psychology,there are a lot of research about this.For chemistry teaching,concept is the core,is the basis of the study.From the teaching experience,I realize that deep understanding of concept is the key to learn chemistry knowledge and solve the problem of chemistry.But in actual teaching process,I also find that students have difficulty in learning concepts,which point to misconception.The first part of the article is to explore the theory basis of misconception.Firstly,we describe the basic theories?characteristics of misconception,and distinguish it with similar concepts.Secondly,we illustrate the course standard and the requirements of the exam outline in chemical equilibrium,as well as the importance of chemical balance.Thirdly,we adopt the comparative study method to analyze the domestic and international research on misconception,including its history origin,present situation and the shortcomings of nowadays research.Finally,we put forward our point of view in this paper combined with high school teaching practice.In the experimental designing part,we interviewed some teachers and students and then wrote a detecting questionnaire of misconception in the chemical equilibrium concept to investigate the students'misconceptions after school.We also designed a teaching plan,which adopting strategies of concept map and PAD class to change the students' misconceptions through teaching practice.And we also use SPSS statistical software to analyze the students learning achievements and emotional attitudes in the late stage.Ultimately it shows that the strategies of concept map and PAD class can effectively change the misconceptions in chemical equilibrium for the students.Through 2-phase test,we find that students have a lot of misconception in the study of chemical equilibrium.through the SPSS statistical software,we analysis from two aspects of learning achievement and emotional attitude achievement,the concept map and PAD class,can effectively change the misconception of chemical equilibrium,and can also produce positive effect in study conclusion.Finally,combining with teaching practice,the last part of this paper puts forward the author's own suggestion and expectation for the basis education of high school chemistry teaching.
