Research On Teaching Design Of Plane Analytic Geometry In Senior High School Based On "Four Bases"

In January 2018,the ministry of education issued the "mathematics curriculum standards for ordinary high schools",which formally proposed the "four basic" curriculum objectives for high school mathematics for the first time.Teaching design is the basis of guiding mathematics teaching activities.In order to integrate the goal of "four bases" into high school mathematics classroom,we need to find a kind of effective method.Taking high school plane analytic geometry as an example,this study tries to solve the following problems: 1.The present situation and problems of plane analytic geometry teaching in senior high school;2.The theoretical analysis of the teaching design of plane analytic geometry in senior high school based on "four bases";3.Based on "four bases" classroom teaching design framework and teaching evaluation scale.Under this background,this paper firstly collects and arranges the teaching of plane analytic geometry,mathematics teaching design,the connotation of "four bases" and the relevant literature materials of "four bases" teaching by means of literature analysis,and clarifies the necessity and feasibility of the research.On this basis,from the plane analytic geometry content cognition,the emotion attitude,the teaching behavior and the problem solving ability four dimensions,through carries on the questionnaire investigation and the interview to the student and the teacher.Master the dynamic situation of the teaching of plane analytic geometry in senior high school under the goal of "four bases",and find out its shortcomings;Through exploring the relevant theories of "four bases" and combining with the current teaching situation,the author draws a conclusion.The six principles of teaching design of plane analytic geometry in senior high school based on "four bases" are the principles of creating teaching situation,permeating mathematical thought,integrating,information technology,inquiry and effectiveness.At the same time,five strategies have been put forward: 1.Doing a good job in the analysis of academic situation and injecting effective experience into the development of the "four bases";2.Comprehensive understanding of teaching objectives,for the development of the "four bases" to clarify the direction of learning;3.Effectively create multiple situations to accumulate emotional experience for thedevelopment of the "four bases";4.Continuously strengthen the mathematical experience to provide an activity process for the development of the "four bases";5.Grasp the curriculum content as a whole and construct the cognitive structure for the development of the "four bases".Based on the above principles and strategies,this study then puts forward the steps of teaching design of plane analytic geometry in senior high school under the "four bases",that is,textbook analysis,learning situation analysis,goal analysis,teaching ideas and link design and classroom evaluation.According to these steps,the classical class hyperbolic and its standard equation are selected for teaching design and practice,so that the "four bases" run through each link.Finally,the research is summarized and reflected,and the corresponding conclusions are drawn as follows: 1.At present,the teaching of "four bases" for senior high school mathematics content is in the blank stage;2.Compared with "double bases",the teaching design of "four bases" reflects more students as the teaching design.The concept of the center focuses more on letting students go through the process of deducing knowledge,and obtaining the mathematical thought and activity experience of solving problems from it.3.Taking the "four bases" as the starting point,in order to make a multi-dimensional interactive judgment on each link of the teaching design in the design of the teaching framework,the mathematical "four basis" teaching evaluation form and the learning evaluation form are derived.Its evaluation method is more diversified,more important is the comprehensive literacy of students,rather than just a certain aspect of the results.In summary,this thesis takes the plane analytic geometry of senior high school as the research content,aims to carry out the teaching goal of "four bases" in the classroom,and develops the teaching research of plane analytic geometry of senior high school based on the "four bases" from two aspects of theory and practice.This helps teachers to better understand and implement the "four bases" in the teaching process,and helps students to accumulate mathematical thinking and mathematical experience in addition to better mastering the "double bases" in the learning process,and helping teachers to better understand and implement the "four bases" in the course of teaching and help students to accumulate mathematical thinking and experience in the learning process.It can effectively improve the quality of classroom teaching and provide the basis for the implementation of other mathematics knowledge in senior high school.However,this study is limited by the author's own research level and practical experience.With the implementation of the new curriculum reform and the continuous advancement of the new curriculum reform,the author believes that the theory of "four bases" in high school mathematics will be gradually paid attention toand promoted by then.This kind of research will be further supplemented and perfected.
