A Comparative Study Of "three-dimensional Geometry" In High School Mathematics Textbooks

The exploration of mathematical content and teaching methods are continuing to advance since the reform of mathematics curriculum in 2003.By departing from the environment of original national unified standards and textbooks,the new round of curriculum's reform are paying more attention to the diversity of teaching materials and try to explore a new change in mathematics education through"one standard, multiple versions ".Aimed at the analysis and research of teaching materials have produced a lot of excellent results, especially in the comparison of'teaching materials.Comparison of Chinese and foreign textbooks, domestic and old version of the textbooks, different versions of the domestic textbook are too numerous to mention.The "solid geometry" content of high school is a very important part in the field of "graphics and geometry" and is the further deepen and exploration to the geography of compulsory education stage. It expands the knowledge of geometry from plane to space.improves students' inherent knowledge,and also paves the knowledge of "solid geometry" in the elective course 2-1. At the same time, the knowledge of "solid geometry" content become more difficult.and have higher requirements for the ability to intuitive observation.spatial imagination, and logical thinking skills.Because the comparative study of the "solid geometry" content in different versions of teaching materials is relatively vacant in the domestic.this article use the textbooks of published by the Jiangsu Education Press and People's Education Press(the version A) which have more extensive use and distinctive characteristics, draws on the excellent experience of this kind of research .use various methods of the literature method, the statistical method, the case law and so on. Comparing and analyzing the discussion of curriculum standard , the master of the overall structure,the analysis of specific content and other angles,it is summed that the textbooks of published by the Jiangsu Education Press and People's Education Press (the version A)are written in accordance with the content requirements and recommendations in the national unity "ordinary high school mathematics curriculum's standards(experimental draft)" for the "solid geometry" of the compulsory part.Due to the different scope of application, the two versions of teaching materials show different writing styles. The textbooks of published by the Jiangsu Education Press is simple and clear,pays more attention to the heuristic teaching through problems, tends to"spiral up"--a kind of teaching methods for mathematical knowledge, and is good at trying a variety of presentation and application to the knowledge ; The version A textbooks of published by the People's Education Press pays attention to the concept of identification, with a clear definition of the module, and emphasizes the contacts between the knowledge and the real life.This article think deeply the research on the writing situation of "solid geometry" content of existing textbooks,find commonness and difference between them,and promote the advantages, abandon the disadvantages.At last,summed up a series of recommendations to the preparation of teaching materials and mathematics teaching on the "solid geometry" of high school.It is hoped that the conclusion of this paper can play an effective reference role for the comparative study and preparation of future teaching materials.
