Application Of Layered Teaching Method Based On Group Cooperation Model In High School Chemistry Teaching

Layered teaching method is an educational teaching method that guides all kinds of students to master basic knowledge,learning skills and methods,and obtain emotional education by classifying students’ learning situation and cognitive level.The group cooperation mode is a learning mode of intra-group and inter-group competition under the guidance of teachers.In order to implement the students’ independent development and reflect the students’ dominant position,the hierarchical teaching method is combined with the group cooperation mode,it is applied in the teaching practice of high school chemistry.Through cooperation,the difficulties in learning are solved.The purpose is to combine the comprehensive development of students with the development of personality,so as to improve students’ interest in chemistry learning,cooperative inquiry ability,and implement the core literacy of chemistry.First,through combing the relevant literature and abroad to understand the research status of layered teaching method and group cooperation mode,define the concepts.Secondly,under the guidance of group dynamics theory and Zone of Proximal Development theory,according to the principle of stratification and group cooperation,the hierarchical teaching method model based on group cooperation mode is constructed.Then,’the quantity of substance’,’the classification of substance’,’the content of ion reaction ’in the compulsory chemistry textbook published by People’s Education Press are introduced as detailed cases,and the seat distribution map design and multidimensional teaching goal formulation are carried out before class.Follow the situation into class,arouse interest in learning;the new lesson teaches,launches the level teaching;group cooperation to achieve the objectives of each layer;group display,display task results;teachers and students summarize,feedback to fill gaps,five aspects of teaching;aftcr class to cooperate to complete the level of homework and group mutual assistance as a supplement.Finally,in a middle school practice in Yulin,Shaanxi Province,the student questionnaire and performance analysis,combined with student and teacher evaluation,teacher observation and interviews,through quantitative and qualitative analysis,summed up the results and shortcomings of this practice.The results show that the layered teaching method based on group cooperation is meaningful in high school chemistry teaching.From the questionnaire,the interest,learning attitude and cooperation ability of the experimental class were 78.22 and 74.12.The performance of the experimental class improves significantly;from the classroom observation record table,student interaction and independent behavior increase to promote the development of students at all levels;from the perspective of teacher evaluation,students ’thinking ability and learning efficiency;from the teacher interview,students ’cooperative inquiry and mutual learning ability improve.Therefore,this study combines layered teaching method with group cooperation mode;the new model improves students’ overall learning ability;the layered teaching method based on group cooperation mode is effective in high school chemistry teaching.
