The Problems And Countermeasures Of Senior Two Students' Conic Curve Learning

Conic curve is a difficult and important point in high school mathematics,and also an introduction to analytic geometry in college.The knowledge point of conic curve is complex,the mathematics thought is rich,the student studies often appears the computation error,the condition transformation is not in place and so on problem.What problems do students have in the process of learning? As a teacher,how to deal with these problems?This article first through the study of conic in nearly five years the national Ⅰ,Ⅱ,Ⅲ volume distribution of examination and the requirements of the new curriculum standard in 2017.The position of conic curve in college entrance examination and teaching material is obtained.Then through the literature method from the conic teaching,problem solving,learning three levels of research.Summarize the existing research results and take constructivism and transfer theory as the theoretical basis.In addition to the above theoretical research,a conic curve learning questionnaire and test paper are developed based on the relevant papers,the Suggestions of front-line teachers and the actual situation of students.A questionnaire survey was conducted among 123 secondary school science students in nanchong no.10 middle school,and the survey results were improved and supplemented by interviews with teachers and students.Through the analysis of the survey results,it is found that there are mainly the following problems in the learning process:(1)Lack of good study habits,there is a psychology of fear;(2)Do not pay attention to the definition of conic curve,understanding is not in place,leading to problems in the application;(3)basic knowledge is fuzzy,especially in terms of definition,formula and geometric meaning of parameters;(4)There are big problems in operation ability,operation method and operation habit,and lack of correct operation consciousness;(5)Unable to use the appropriate mathematical thinking method to solve the problem,the reasonable transformation of conditions blocked.According to the problems of the above students in learning,this study proposes the following coping strategies:(1)Pay attention to the student's study situation,establish the courage to overcome the difficulty;Build the confidence to learn and overcome the psychological fear;(2)Attach importance to the formation of concepts,deepen the understanding of definitions,reasonable use of definitions to solve simple problems;(3)Tandardize students' problem-solving process,regular time training,in doing the problem time,problem solving habits,writing process to develop good habits;Reasonable selection of methods,reduce the amount of calculation,pay attention to the accumulation and application of parametric equations and common conclusions,improve the accuracy of calculation;(4)In the usual teaching in the infiltration of mathematical thinking and methods,develop the habit of drawing,experience the combination of number and shape;Pay attention to the content of the textbook cohesion,highlight the idea of function and equation;Make good use of image property,reasonable induction conjecture.
