Research Of Chemistry Class Of Exercise Teaching Based On Group Work

The importance of cooperation in today's social team has become increasingly prominent,collaboration with others is an inevitable choice,but the current high school students are mostly Only Children,and others lack of awareness and ability to cooperate.So how to enhance the ability of students to cooperate,is an important issue placed in front of China's basic education.Students in the prevalence of learning inertia,in the group of cooperative learning,you can get the most effective and most rapid help.This paper first summarizes the existing research on cooperative learning and chemistry exercises in chemistry teaching,and puts forward that the teaching of chemistry exercises based on group cooperative learning should follow: the principle of subjectivity,the principle of cooperation,the principle of hierarchy,openness in principle.This paper further studies the teaching model of chemistry exercises in the course of "independent questioning-independent revision-group discussion-group discussion-summary and improvement-standard test-group evaluation",and from the reasonable grouping,selected exercises,timely guidance and encouragement The evaluation of several aspects of the implementation of the group to discuss the cooperative learning of chemistry exercises teaching strategies.The grouping method is to use the "group homogeneity,group heterogeneity",after the completion of the group members of the team to cooperate in the way of training,the development of group cooperative learning rules;exercises to focus on basic knowledge and basic skills training,attention to students The students in the process of cooperative learning,teachers should promptly inspect and conduct effective guidance;in order to promote the smooth progress of cooperative learning,you can take a variety of incentives to evaluate the way,in order to promote the development of cooperative learning.On the basis of these theoretical analysis and research,this study also designed two examples of "atomic structure and element" and "carbon and carbon oxides" based on group cooperative learning exercises.In order to verify the validity of the theoretical conception and teaching design of this study,this study chooses the experimental class and the control class to carry out the one-year teaching practice research.The research shows that the teaching mode and strategy tried by this institute can help to improve students' chemistry Academic performance,student awareness and skills have also been a certain degree of training.
