A Comparative Study On Quadratic Function In Different Learning Periods

Quadratic function plays an important role in high school teaching,so in order to lay a solid foundation for further study,it’s necessary to discuss the principle of quadratic function teaching,learn about the effect of function thoughts in integral teaching,and develop their math ability which are math modeling,abstraction calculating.At the same time,quadratic function is widely used in our daily life and production,so it should be studied carefully in different learning periods teaching.Many scholars focused on the links of quadratic function teaching in different periods,but they didn’t analyze and compare the quadratic function teaching.This thesis bases on the textbooks of Shaanxi and has a comparative research on quadratic function teaching in different learning periods.The thesis selects the document analysis and questionnaire survey to study the content distribution,link and important points in high and university entrance exam based on the “middle school math curriculum standard”.Then according to the questionnaire from different teachers and students and the author’s half years teaching practice,then the thesis puts forward some suggestions which can be tried in quadratic function teaching.The thesis is divided into six parts.The first part expounds the objectives and significance and introduces the study methods.The second part is the relevant bibliography and theories.In the third part,the author analyzes the quadratic function’s distribution in different periods and explains systematically,then discusses the linking problems based on the curriculum standard.Besides,the situation of quadratic function in high school and university entrance exam is carefully analyzed by comparing examoutline.In the fourth part,the thesis analyzes the results from the questionnaire and discusses the problems of quadratic function teaching.The fifth part is based on the third and fourth part,the author combines the excellent cases in her teaching practice and analyzes the problems of quadratic function teaching in different periods,then puts forward some teaching advice.The last part is the summary and reflections,including the innovation and shortcomings.
