The Teaching Status And Teaching Design Case Study Of Conic Section’s Topic Course

Conic,as one of the main knowledge in the college entrance examination,is one of the compulsory examination points of the college entrance examination.It is not only complicated in the process of solving problems,but also often connected with other knowledge to examine students’ comprehensive application ability,which has been paid attention and concern by educators.Although a large number of educators continue to study and explore the content of conic,but in the actual teaching of conic section,the accuracy of students to solve problems is often not high,there are still many difficulties in the process of learning and solving problems.Therefore,this paper analyzes and sorts out some knowledge of conic curves in the form of a special topic and makes a series of investigations to make teaching design of related special courses,in order to improve students’ understanding of conic curves,form problem-solving thinking,and provide some help and reference for front-line teachers’ teaching.In this paper,literature analysis,questionnaire and interview methods were used to study the following contents: Firstly,literature review and collection of conic curve related literature were conducted to understand the current teaching and learning situation of conic curve,the research situation of problem solving strategy and teaching research situation;At the same time,questionnaire survey and interview were conducted for students and teachers respectively,Through the investigation,it is found that there are generally six problems in the process of conic curve learning: first,ignore the importance of problem solving strategy accumulation;Second,there is fear of conic curve;Third,the understanding of basic concepts is not clear enough;Fourth,the computing power needs to be improved;Fifth,lack of geometric transformation ability;Sixth,study habit is not good.Through the investigation,it is also found that the current theoretical system of thematic course teaching is not complete and lacks theoretical guidance,which leads to difficulties in the implementation of teachers and requires further exploration and research.This paper puts forward some ideas and strategies for solving the problems of eccentricity,symmetry and maximum value.On the basis of problem-solving ideas and strategies,combined with students’ learning conditions,this paper puts forward five links of teaching design of thematic courses: determine the theme of thematic courses,formulate teaching tasks,select teaching methods,design teaching activities,improve teaching design,and design the teaching of three conic curve thematic courses based on this.
