解析几何

Plane analytic geometry is a important content in the mathematics curriculum of high school, which embodies powerful function of analytic method and algebraic method in the depicting curve. It reflects important idea of the combination of number and figure. Learning the course is very important for students to improve mathematics thought ability. Teachers and students are engaged in teaching and learning by the textbook, so it is necessary to analyse plane analytic geometry textbook.

Textbook is not only the primary basis for students to grasp knowledge and method but also resort and carrier to train capability. New textbook has been tested in some provinces and cities since 1997, some educational and teaching concepts in new textbook inosculates with new mathematics course which is being tested now, it has taken great role for the transition of teachers' teaching idea and students' learning way. This paper will analyze Plane Analytic Geometry high school textbook of 2004 edition which is published by People's Education Publishing House in some aspects such as content structure, educational function, psychological characteristic according with student cognizance and teaching through the method of content analysis, investigation, comparison and statistical analysis . The paper's purpose is to excavate the potential value of the textbook and understand educational idea and concept of new textbook so that students can grasp more basic thought of analytic geometry in teaching and can learn studying and discovering and solving problem ,at the same time it builds a kind of independent, disquisitive, cooperative and lifelong learning pattern.

教材既是学生掌握知识和方法的主要依据，又是培养学生能力的凭借和载体，自1997年新教材在部分省市实验以来，新教材中所体现的一些教育教学理念与现在正在实验的高中数学新课程相吻合，对教师的教学观念和学生的学习方式的转变都起到了很大的作用，本文将对人民教育出版社2004版普通高中教材中的平面解析几何部分通过内容分析法、调查研究、比较研究、统计分析等研究方法从教材的内容结构、教育功能、符合学生认知心理特点、教学等几个方面进行分析，目的是挖掘教材内容的潜在价值，真正领会新教材所蕴涵的教育思想和理念，以使教师在教学中能够让学生更多的掌握解析几何的基本思想，以培养学生学会学习、学会发现问题和解决问题，为学生构建一种自主的、探究的、合作的、终身的学习模式。
