The Group Cooperates To Study The Applied Research In The Junior Middle School Chemistry Review Class

One of the key points of the curriculum reform in elementary education in the new century is to change the way students learn, advocate autonomy, inquiry and cooperation learning. At present, there are many schools in the domestic teaching reform mode, and a large number of curriculum schools have emerged. However, there are few reports on the implementation of teaching reform in junior middle school chemistry review. Based on the actual situation of the school, combining with the learning psychological characteristics of junior students, centering on the problem of chain, with team cooperation as a platform,to study case as the carrier, cooperative learning group in chemistry review course.On the basis of theoretical research, two parallel classes in the third grade of Erling Middle School in Danyang City were selected teaching and research for three and a half months. Experimental class teaching using cooperative learning group to review, the control class is to review the teaching with the traditional teaching mode. Before the experiment, the students' interest in chemistry learning and attitudes of chemistry was investigated. The survey(pretest) showed that there was problems that students had poor autonomous learning, the way to learn chemistry is not good and so on.After the end of the experiment, two classes of students to test the results of chemical test, with EXCEL test results for T test, the statistics show that the experimental class student performance of chemistry was significantly higher than the control class student achievement, and there are significant differences. At the same time a questionnaire survey(post test) on cooperative learning group in chemistry review course of the third grade, the statistics show that the majority of students like group cooperative learning method, is willing to exchange discussion and help students in the group.Through teaching practice, confirmed that the group cooperative learning can stimulate the students' chemistry learning interest to improve the efficiency of classroom learning, to promote the achievement of three-dimensional goals of students, and at the same time can improve the students' ability of cooperation and the sense of responsibility.
