High School Math Coordinates And Parametric Equations Research

In the mathematics course of senior middle school, coordinate system and parametric equation, as a monographic project, is one of the optional parts. It is on the foundation of learning required course,like analytic geometry, trigonometric functions, plane vector etc. In college entrance mathematical examination over the years, both coordinate system and parametric equation questions appeared in different forms, that is relatively easy points to scroe. So it needs to be mastered. This article carries on statistics and classification for matriculation texts in recent six years, then works out and explain them one by one. Corresponding solutions and teaching suggestions are acquired finally.Firstly, making statistics on all the question types and examination points of coordinate system and parametric equation in college entrance examination from 2010 to 2015, to conclude their distribution features. Then using symbolic-graphic combination, analogical models, induction and transformation etc, to analyze and solve the same sort of typical question of the examination, to summarize ideas and ways of solution. Eventually, based on analysis and summary, adjusting content, sequence, and lesson period in teaching process. To arrange teaching reasonably, and improve traditional lecture method, that is, student Initiative Inquiring learning- oriented, fully arousing student interest and lead students to proceed from the actual conditions of life, integrating learned knowledge with living practice, meanwhile using relevant mathematical software to increase teaching means, to make the teaching content more visualized. Focus on teaching approaches penetrated into the process, to make students master knowledge from the particular to the general. According to these to design teaching strategy so as to make the key contents of teaching stand out for teacher, and the goals of learning clear-cut for students.From summarizing ways of solution to designing teaching case, this article is aimed at providing some reference for students and teachers, broadening students' horizons and improving teaching method of teachers, contributing my small efforts to high school mathematical teaching.
