Case Study Of Classroom Teaching In Junior Middle School Mathematics Enrichment Curriculum

The research is based on the design research of "planning-action-observationreflection and replanning",and take four excellent teachers' teaching videos of middle school mathematics enrichment curriculum as the object of analysis.Through video study,we carried out qualitative and quantitative analysis from the aspects of teaching objectives,teaching activities and teaching interaction,and then summarize the classroom teaching characteristics of four excellent teachers who carry out two themes of mathematics enrichment curriculum in junior middle school.The study found that the differences and commonalities between the teaching characteristics of the junior middle school mathematics enrichment curriculum which topics are "Mathematics and Applications of Life" and "Mathematics Thoughts and Methods".The teaching differences between the two types of topics are mainly reflected in the design of activity tasks and types of activities under different teaching goals.Among them,the "life mathematics" focuses on the level of life experience mathematics,and mainly focuses on the solutions and experimental activities of training and exploratory questions.The common characteristics are mainly reflected in the organization of activities,interaction modes,types of questions and feedback,which are mainly organized in the form of whole-class communication activities,and the time distribution of each activity phase is relatively close.According to the commonalities and differences of the teaching characteristics of the two kinds of enrichment curriculum,in order to reflect the flexibility of instructional design in multiple dimensions,we can dig through teaching material resources and design activities around the problem,and get the following teaching inspiration for the implementation of the junior middle school mathematics enrichment curriculum.In the implementation of the mathematics enrichment curriculum,we should strengthen the teaching materials.What's more,the content of the basic curriculum subject should be reconstructed to form the teaching goals.On the basis of clear learning objectives,we should set different levels of activity tasks,and choose the appropriate activity type in combination with the theme to enrich the expansion content and reflect the openness of classroom teaching of the enrichment curriculum.In order to create an open and harmonious classroom atmosphere,teachers should flexibly choose different forms of activity organization and give students corresponding exploration time and feedback for different types of questions,so that can increase the opportunities for students to experience,explore,operate and cooperate,and reflect student-centered.
