Research On The Teaching Design Of "Plane Analytic Geometry" Unit In High School

Mathematics Curriculum Standards for Ordinary Senior High Schools(2017 edition,revised in 2020)emphasizes the thematic learning unit model,and the unit teaching design with the subject concept as the core is the key to deepen the curriculum reform.This paper mainly uses literature research method,interview method,case analysis method to study the teaching design of "plane analytic geometry" unit.Design plane analytic geometry as a unit.On the basis of clarifying the principles and procedures of unit teaching design,interviews were conducted with 4 first-line high school math teachers in H city,and the unit teaching design of "planar analytic geometry" of first-line high school math teachers in H city was collected,in order to understand some high school math teachers in H city.The current situation of teaching design of "Planar Analytical Geometry" unit.By analyzing the interview results and the collected unit teaching design,it is found that some high school mathematics teachers in H city only have a preliminary understanding of the unit teaching design,and do not pay much attention to the unit teaching design.The main reasons for this phenomenon are:(1)There is no general environment for unit teaching design;(2)Teachers have heavy teaching tasks and have no time to carry out unit teaching design;(3)There is a deviation in the understanding of unit teaching design;(4)Focus on mechanical training,ignoring the cultivation of core literacy.In view of the above phenomenon,the following suggestions are put forward:(1)Accurately interpret the curriculum standards and clarify the general direction of education and teaching;(2)Strengthen theoretical study,master and apply unit teaching design;(3)Strengthen the teamwork of unit teaching design;(4)Pay attention to the cultivation of students' core literacy;(5)Highlight the main line of the unit and reasonably construct the knowledge system;(6)Pay attention to the production process of knowledge;(7)Pay attention to the integration of information technology and curriculum.And according to the basic process of unit teaching design,he wrote a complete unit teaching design of "Analytical Plane Geometry" and the teaching design of "Analytical Plane Geometry" during the class,for the reference of mathematics teachers in first-line high schools in H city.
