Teaching Research On "Coordinate System And Parametric Equation"

With the continuous advancement of the new curriculum reform process,the new round of high school curriculum reform has entered a critical period,and it is imperative to explore a new high school teaching model.As a bridge connecting geometry and algebra,analytic geometry plays an important role in high school mathematics,especially coordinate thinking is the key content of high school mathematics.The study of coordinate system and parametric equation can effectively expand students’analytical geometry and provide a new solution to the previous knowledge.This article obtains information through questionnaires,case studies,and literature research methods.Using the familiar curve parameter equations and simple curve polar coordinates,students can have a comprehensive understanding of parametric equations and coordinate method ideas,helping students to further improve their ability to use the knowledge they have learned to solve practical problems,and then let students learn mathematics.A comprehensive understanding of cultural values,applied values,and scientific values.This study intends to investigate and analyze the learning situation of the coordinate system and parametric equations of the senior high school students in Wuyuan Middle School by means of questionnaires,aiming to solve the following problems:(1)What are the specific requirements of the college entrance examination for this topic,and how should these requirements be reflected in the teaching design?(2)What effective teaching methods should high school mathematics teachers use?(3)How should high school mathematics teachers correctly guide students to form a combination of numbers and shapes?(4)How does a high school mathematics teacher conduct a round of reviewing instructional design?In the teaching,combined with the coordinate system and parametric equation case study and its own teaching practice experience to summarize the teaching strategy,and deeply analyze the necessity of the coordinate system and parametric equations,and provide a new idea for the study of the topic content.In the round of review,the idea of problem string is adopted,that is,the idea of setting small problems under big problem is used for teaching design.In the teaching,the problem-guided teaching mode is adopted to guide students to learn the coordinate system and parametric equations from shallow to deep.In the teaching,the students are guided to draw more pictures,use images to help students learn to master the content of the topic,infiltrate the idea of combining numbers and forms in teaching,and use a variety of information technologies to cultivate students’ interest in this topic.Do this topic and the previous high school.The connection of the knowledge system.
