A Study On Students' Participation In Senior High School Chemistry Exhibition Class Based On CPUP Model

Since the implementation of the new curriculum reform,in order to improve the effectiveness of chemistry classrooms,front-line teachers have paid attention to students' classroom participation,and significant changes have taken place in teaching design and teaching methods.Although there are many researches on student class participation at home and abroad,there is no systematic and operable tool.Professor Zheng Changlong of Northeast Normal University and his team proposed the CPCP model of the chemistry classroom teaching system,and on this basis,further constructed the CPUP model of the chemistry classroom teaching system.The series of models proposed for the chemistry classroom teaching behavior and the study of teaching content provides a quantitative and refined method,and also provides a new perspective for students' participation in the chemistry class.The two lessons selected in this study are both “one teacher,one excellent class,one lesson for one class”.Based on the literature research method,video analysis method and statistical analysis method,based on the CPUP model of the chemistry classroom teaching system,the teaching behavior pair and teaching behavior chain of the two selected "the simplest organic compounds-methane" demonstration classes,analyze from the four aspects of type,frequency,time and distribution,and draw conclusions.Through the research,it was found that the teachers of the two demonstration classes designed a large number of student-oriented teaching behavior pairs in the classroom to allow students to learn independently and actively participate in the chemistry classroom.At the same time,it was also found that the ratio of frequency and time spent in teaching behavior chains with higher classroom participation was much higher than the teaching behavior chains with lower classroom participation,indicating that students had higher classroom participation.Based on the study of the above teaching behaviors,the author puts forward suggestions for the majority of front-line teachers.
