Research On Review Teaching Of Conic Sections In Senior Grade 3

Conic curve is one of the important contents of analytic geometry in senior high school.Learning conic curve can cultivate students' mathematical discovery ability and mathematical problem-solving ability.At the same time,conic curve is also the content of the annual college entrance examination,it involves a wide range of content,there are basic knowledge of the investigation,but also with straight lines,triangles,sequence of numbers,plane vector and so on.The investigation of this part of the content requires higher students' mathematical thinking ability,so that the students' score rate is low every year.If teachers do their best to review this part of the content and find effective review strategies,then this will be of far-reaching significance to the development of students' mathematics.In this study,the influence of senior school conic review teaching strategy based on CPFS structure theory on students' mathematics achievement was explored from the following two aspects,taking Class 5(6)of Senior School Science(5)(6)as the experimental object.First of all,the present situation of high school science students learning conic curve is investigated in order to understand the students' mastery of conic curve,review methods and listening habits.At the same time,a questionnaire survey was conducted among 7 senior high school mathematics teachers on the review of conic curves,and the teaching status of teachers reviewing conic curves was preliminarily understood.Secondly,based on the analysis of the above survey results,the conic review experiment based on CPFS structure theory is carried out,and the teaching strategy is put forward to carry out the teaching and classroom record.Finally,the difference test of students' mathematics scores before and after the implementation of teaching is carried out.The experimental study shows that the conic review teaching strategy based on CPFS structure theory can significantly improve the students' mathematical performance in statistical sense.These teaching strategies include: revealing the concept connotation strategy from many angles in the concept review,forming the concept system strategy,strengthening the concept application strategy,paying attention to the process strategy,paying attention to the variant strategy,forming the proposition strategy,strengthening the proposition application strategy in the proposition review,paying attention to the process strategy,paying attention to the variant strategy,forming the proposition strategy and strengthening the proposition application strategy in the proposition review.Comprehensive problem review in the variant teaching strategy,reorganization and integration strategy.This study provides a reference for first-line teachers to carry out the review teaching of conic curve and guide students to construct the concept domain,concept department,life question domain and proposition department of conic curve.To help it effectively complete the task of mathematics education and teaching in senior school.
