Application Of Flipped Classroom Model Based On Problem Orientation In Junior High School Mathematics Teaching

Junior high school mathematics is an important subject connecting the advanced high school and even university stage.Using problem-oriented method can help students to sum up their knowledge points more efficiently.This paper will focus on the key points of the connotation of the problem-based teaching approach and the implementation strategies that are combined with the flipped classroom in order to help the quality of classroom teaching.Firstly,this study reviews the research of flipped classroom teaching model and problem-based teaching model in recent years and clarifies the research questions of this paper: What is the research status of flipped classroom,and how to combine the problem-oriented teaching model and the flipped classroom teaching model.Secondly,it attempts to build a flipped classroom teaching model based on the problem-oriented teaching model by combining previous flipped classroom teaching models.It consists of four parts: the introduction stage of teaching problems,the independent problem-building stage,the problem-oriented teaching practice stage and the interactive communication stage.Under this model,take the quadratic equation of one variable as an example,a two-month practice was done in a secondary school through action research with the common advice and guidance of the teachers in the teaching and research group.A detailed analysis was done before,during and after class,and the teaching suggestions are as follow.Reasonable disassembly of knowledge points,production of high-quality problem-oriented video,reasonable and strict introduction of problem design before class;When in class,from the problem inquiry,problem summary,problem expansion to complete the classroom flip;after class,complete after-class consolidation from after-class mutual evaluation,after-class test and after-class expansion.Thirdly,combined with empirical research and teacher interview analysis,this paper puts forward a strategic analysis of the difficulties of flipped classroom implementation at the present,such as changing the teaching relationship,focusing on asking questions from the perspective of students' learning and thinking,playing the role of the main body of student learning,and using multimedia equipment flexibly.The opportunity to ask questions should be seized to guide students to develop a sense of questioning and reflection.Finally,the relevant results of the study were drawn: a theoretical framework of the problem-oriented flipped classroom teaching model was constructed;reference cases were provided in the implementation of the flipped classroom in junior high school mathematics;the combination of problem-oriented and flipped classroom brought help to the junior high school mathematics classroom,guiding students to generate mathematical thinking and enhancing their mathematical ability;however,the current situation of the flipped classroom based on the problem-oriented model in the application of mathematics teaching for junior high school students was not not optimistic,and thus the degree of adaptation to the problem-oriented flipped classroom has yet to be improved.
