Research On Classroom Teaching Behavior Of High School Chemistry Quality Class And Normal Class On CPUP Model

With the implementation of a new round of college entrance examination reform and the promulgation of new curriculum standards for chemistry,the requirements for chemistry teachers are increasingly high.How to improve the classroom efficiency in the limited classroom teaching time is particularly important,and the direct factor that determines the classroom efficiency is the classroom teaching behavior between teachers and students.In quality classes,the classroom teaching behavior is often diversified,novel and unique,which can greatly activate the classroom atmosphere and improve the classroom efficiency.However,there are more or less deviant classroom teaching behaviors in normal classes.Therefore,it is of great practical significance to study the teaching behaviors of quality class and normal class.This study is based on the model of classroom activity as the theoretical framework of CPUP model,with the nature of the chlorine gas,the properties and applications of sodium metal and the properties and application of sodium carbonate three quality class and three normal class as the research object,through literature research,classroom observation method,quantitative analysis,comparative analysis and other research methods,from the teaching behavior and teaching behavior chain of frequency and time to study high school chemistry element compound quality class and normal class teaching behavior.The study found that the differences in teaching behaviors between high quality class and normal class of elements and compounds were reflected in the following four aspects :(1)The frequency and types of teaching behavior pairs are different.In the quality class of elements and compounds,teachers' teaching behaviors are more frequent,more diversified and more unique.(2)Time arrangement of teaching behavior pair is different.In the quality class of elements and compounds,teachers pay more attention to the interaction with students,and can arrange more time for students to carry out hands-on operation,report communication,group report,independent thinking,etc.(3)The frequency and types of teaching behavior chain are different.In the quality class of elements and compounds,each kind of teaching behavior chain is involved,mainly including three kinds of teaching behavior chains: "autonomous","communicative" and "direct response".However,in the normal class of elements and compounds,the chain of "autonomous" teaching behavior with the highest degree of student autonomy did not appear,and the main chain of teaching behavior was "direct answer" and "self-answer".(4)Time arrangement of teaching behavior chain is different.In the quality class of elements and compounds,teachers can arrange teachers' activity time and students' activity time in a more reasonable way,and there is no teaching deviation behavior of "full teaching".After summarizing the research results of this paper,the author puts forward some Suggestions on how to improve the classroom teaching behavior,hoping to give some reference and enlightenment to the majority of chemistry teachers.
