Research On Teaching Practice Of Classification View In High School Chemistry Review Class

This thesis is based on the cultivation of the classification view of students in the middle school chemistry review class.Through the research background of classification concept and the research status at home and abroad,it is found that the teaching theory of middle school chemistry review class based on the construction of classification concept is relatively mature,but it is lacking the support of teaching practice.Based on this,the purpose and ideas of this research are put forward.From the perspectives of teachers and students,the author investigated the application of teachers and students to the classification concept and the application status of classification in the middle school chemistry review class.The survey found that although high school students and first-line chemistry teachers have realized the importance of the cultivation of classification concepts to students' development,they still need to be further implemented in specific teaching practices.To response to this problem,on the basis of the overall analysis of the textbook "Chemistry 1",the author reorganized the knowledge content of the third chapter and the fourth chapter,designed the teaching plan and carried out the teaching practice,and based on the test,the results of the experimental class and the control class were analyzed.Studies have shown that the implementation of classification teaching in the middle school chemistry review class is conducive to students achievement and ability development.It is suggested that middle school chemistry teachers can carry out the teaching practice of the chemical review class of classification construction from the aspects of content selection,goal formulation,situation creation,interest stimulation,problem design,media application,activity development,and timely evaluation.
