| At present,the basic education curriculum reform has entered the era of core literacy.The core quality points to students' independent learning ability and lifelong learning ability,and puts forward new requirements for students' learning mode and teachers' teaching mode.In junior high school mathematics teaching,how to change or optimize the existing mathematics classroom teaching mode based on the development of students' core literacy and mathematics subject core literacy is not only a very practical problem,but also has the value of theoretical discussion.Based on this,this study takes mathematics "one teacher one excellent course" on the national education resources public service platform as the research object,and takes Joyce and Weill's teaching model concept as the theoretical framework,analyzes the teaching model characteristics of junior high school mathematics "one teacher one excellent course" in different content fields and different course types,and explores the effective mathematics teaching model that points to the development of core literacy.In this study,35 excellent mathematics courses were selected from "one teacher one excellent course" of junior high school mathematics on the national education resources public service platform(mathematics courses with four content themes: 5 "image and nature of inverse proportion function",5 "diamond judgment",5 "stability of frequency",5 "synthesis and practice";three types of mathematics courses: 5 new courses,5 review courses and 5 section paper lecture)is the sample of the study.Based on the characteristics analysis framework of Bruce Joyce and Martha Weil and the practice of junior high school mathematics teaching in our country,this paper puts forward three dimensions of the characteristics analysis of the teaching model of this study: the interaction between teachers and students,the supporting system and the structural system.With the help of the video case analysis tool,this paper analyzes the characteristics of the teaching mode of 35 excellent mathematics courses in junior middle school from three aspects of the interaction between teachers and students,the supporting system and the structural system.It is found that the teaching mode of mathematics excellent course in junior middle school shows the following characteristics: in the type of teacher-student interaction,the main type of teacher-student interaction behavior is teacher class interaction,the lack of teacher group interaction,and the interaction between teachers and classes is carried out in a cross way.In the aspect of language interaction between teachers and students,mathematics classroom has gradually changed from "teacher centered" to "teacher-student cooperative" and "student centered".In the aspect of supporting system,the supporting conditions of "Ministerial excellent course" classroom teaching are diversified: pay attention to the integration with information technology and the use of classroom props to enrich the form of classroom teaching.In terms of the structure of teaching mode,the diversification of teachers' teaching link design enriches classroom teaching activities.According to the characteristics of "Ministerial excellent course" in junior high school mathematics,the following enlightenment is given to explore the teaching mode of core literacy: in the aspect of teacher-student interaction,the classroom of core literacy training is the classroom of teacher-student interaction: we should use a variety of interaction types and language interaction forms to cultivate students' core literacy.In the aspect of supporting system,teachers should try to use a variety of teaching props and means to enrich the classroom teaching form and cultivate students' mathematical culture.Provide students with real practical experience to cultivate students' inquiry ability.In the aspect of structure system,teachers should guide students to learn independently and cooperatively to cultivate students' sense of responsibility. |
