Research And Practice On Teaching Design Of High School Mathematics Unit

Under the background of the new era,the "General High School Mathematics Curriculum Standards(2017)" puts forward the six core qualities of mathematics,guides the entire curriculum structure with themes,and advocates teaching in the form of major concepts of the subject.However during the internship,the author found that many teachers teach in the form of segmented knowledge points,which is inconsistent with the new curriculum standards.In order to help them jump out of the previous teaching mode.This article focuses on unit teaching,takes the knowledge of the plane vector chapter as the carrier,mainly discusses the following two issues:(1)Taking the plane vector chapter as an example,how to systematically carry out unit teaching design?(2)Compared with traditional class-time teaching,what is the effect of unit teaching design?On the basis of combing relevant literature and selecting appropriate research methods,the following conclusions can be drawn:(1)In the systematic design of the plane vector chapters,it can be carried out in three parts:the planning of large units--the design of small units--the teaching of class hours.Among them,the planning of large units is the guidance,the design of small units is the core,and the teaching of class hours is the implementation.In the overall design,we should grasp the thread and highlight the main theme.(2)In the specific design ideas,firstly,the contents of the chapter should be integrated and the teaching objectives of the unit should be formulated;Second,determine the clues of unit development and divide the content into several small units;Third,it is necessary to plan small units and arrange class hours.Finally,on the basis of teaching analysis of small units,class teaching is carried out from the perspective of unit.In the design of the new course,we should let students master the essence of knowledge and grasp the logical structure.On the design of exercise class,we should let students grasp the general method of solving problems.(3)In the practice of unit teaching,the unit teaching and traditional class teaching are implemented together,the results show that the teaching performance under the unit teaching mode is more excellent.This teaching mode can help students better understand the basic concepts,recognize the nature of the problem,grasp the context of knowledge and master general methods.On the basis of research,the following suggestions concerning unit teaching design are put forward:(1)Grasping the essence of knowledge and integrating teaching resources is the foundation;(2)Based on students' academic conditions,setting teaching goals is the key;(3)Linking with learned knowledge,Focusing on combing and transforming is a means;(4)To improve the design dynamically,and to do a good job of reflection after class is perfect;(5)To strengthen unit teaching practice and enhance teaching creativity is the goal.
