| In recent years,the country has issued a double-reduction policy.The author advocates the art education which combines in-class teaching and extracurricular activities.This paper refers to various literature,based on the interaction theory of Mead,the complementary theory of Danish atomic physicist Bohr and the reciprocal teaching of Muska.Moston,and sorts out the relationship between the three interactions in the combination of in-class and out-of-class.First,there are interaction and complementary behaviors between teachers and students in in-class teaching and extracurricular activities respectively.The second most important thing is that the combination of in-class teaching and extracurricular activities has the interaction of teaching form.In addition,through the combination of in-class and out-of-class,students can guide the practice of activities with the theoretical knowledge they have learned,which is the interaction of students’ thinking ability and behavior ability.Therefore,on the basis of in-class teaching and extracurricular activities,teaching content and time are complementary to each other to varying degrees,and the thinking and behavior of students and teachers are also complementary because of the interaction in and out of class.Similarly,reciprocity means that under the drive of interaction and complementary,the ability of students and teachers is developed.Students can improve their interest in learning and develop their own individual needs,and teachers can improve their teaching ability and design better art courses.To sum up,interaction,complementary and reciprocity are gradually linked.The author conducted a survey on H Middle School in Chengdu by means of questionnaire survey and interview to understand the basic problems of art teaching in this school.Then designed teaching practice cases according to the strategies and suggestions.The "three reciprocal" teaching is applied to practice.The "three mutual" teaching combined with both inside and outside class can solve some problems in H Middle School,and better cultivate students’ core quality and comprehensive ability of art.Therefore,the combination of in-class teaching and extracurricular activities is a "three-mutual" teaching with the characteristics of interaction,complementary and reciprocity. |
