The Construction And Application Research On The Stratified-cooperative Learning Mode For Junior Middle School Math Based On Activity Theory

Stratified-cooperative learning is a noticeable trend in the development of classroom education reform in schools for our country,which satisfies the requirements of the times of knowledge.This paper chooses stratified-cooperative learning mode based on the activity theory as the subject.Through practice,we try to build a general teaching mode of stratified cooperative learning based on the activity theory in traditional middle school mathematics classroom,and put forward the seven-step teaching process,that is,"pre-learning-lead to learn-self-learning-mutual-learning-seek to learn-learning consolidation-post-learning".Furthermore,based on the concept of learning activity system,we point out the principal activities of the teachers and students,the coordination of parents.and classroom teachinsg organizational process in each step respectively.Compared with the actual situation of our school's original stratified teaching,the learning mode we introduce is relatively easier to practice and has practical significance to guide and promote the reform of classroom teaching.This paper mainly considered the following items focusing on the construction of the stratified-cooperative learning mode based on activity theory:1.The author presents stratified-cooperative learning background to summarize domestic and foreign scholar research of stratified-cooperative learning and describe the research approach we plan to adopt in this paper.2.The author elaborates the connotation of stratified-cooperative learning class teaching mode based on activity theory and the related theories of cooperative learning.3.The author analyzes the advantages and disadvantages with respect to the traditional stratified teaching mode,and then formulates a general stratified-cooperative learning model based on activity theory for junior middle school math class.4.Based on the junior middle school classroom stratified-cooperative learning and teaching process we propose,from the preparation,implementation and experimentation,the author discusses the application of the teaching mode in the concrete teaching strategy.5.Through the questionnaire survey and data processing,the author analyzes the effect of the application in junior middle school class stratified-cooperative learning and teaching mode based on activity theory and introduces problems that should be paid attention using in the application of this learning mode.The result of this research indicates that adopting the stratified-cooperative learning mode we introduce,the students in the experimental class have made notable progress on the following four aspects,that is,math scores and the polarization among students,class learning behavior,math learning interest and ability,the relationship with the classmates.The innovation of this article is that the stratified-cooperative learning mode we clearly outlined in this thesis not only has a theoretical analysis but also concrete operation in practice and provides an option for junior middle school class launching group cooperation learning and teaching reform.
