The Teaching Practice Research Of Conic Curve Under Constructivism Learning Theory

The conic curve module is an important chapter of analytic geometry,and its content is more.Because the "Ordinary High School Mathematics Curriculum Standards"(2017 edition)has higher requirements for this module,it is also the focus of the college entrance examination,so the module is difficult to learn.The teaching effect is not ideal.The author investigates the teaching status of the current high school math conic curve through questionnaire interviews.Through the analysis of the survey results,combined with the knowledge view,mathematics learning view and mathematics teaching view under the constructivist learning theory,the current high school mathematics conic curve Teaching is conducted.Constructivist learning theory requires the full play of the student's dominant position,the teacher's leading role,allowing students to actively participate in the classroom teaching,to enhance students' interest,rather than passive acceptance of knowledge.On the basis of the existing mathematical knowledge or experience,students construct their own knowledge systems under the guidance of teachers,and actively grasp the knowledge content.The author also carried out teaching practice on the basis of theory,and expounded the research significance of this paper through the analysis of the practical results.This paper draws on the research of many scholars at home and abroad,combined with the author's internship experience,puts forward the teaching principles and teaching measures of the conic curve under the constructivist learning theory.The innovation of this paper lies in the combination of the four principles mentioned above,namely,the creation of the principle of situation,the principle of teacher-led students as the main body,the principle of conceptual teaching,and the principle of mutual cooperation.The conic curve is given from six aspects.The teaching measures are the construction process of teachers to complete their own knowledge system;the introduction of problem situations in the process of introducing conic curve knowledge,the introduction of mathematical culture,the introduction of information technology;the guidance of students in the process of conical knowledge understanding,encourage students Intuitive conjecture;in the application process of conic curve knowledge,infiltrate students' mathematics thoughts,strengthen students' practical application;systematic process of conic curve knowledge and construction process of teachers' students' after-school reflection.The constructivist learning theory is integrated into the complete teaching process,with examples as support,and some suggestions for conic curve teaching.
