The Evolution And Development Of Solid Geometry In High School

Along with the boost of the new curricular reform , the basic education is at an important change in china, and teaching material is an important carrier of educational reform, so researching teaching materials and rethinking the curricular reform in recent decades has an important practical significance to the current or future curricular reform .In view that the knowledge of solid geometry has an important role in high school, this thesis selects the content of solid geometry of version-1983, version-2001, version-2007-A published by People's Education Press, and researches the evolution and development of solid geometry in nearly three decades by the literature method, the method of the content analysis and the questionnaire survey, and strives to point to the characteristics of mathematical courses and the transitions of the educational theories.Solid geometry in the 1980s had the advantages which included strong system ,the obvious discipline characteristic, highlighting axiomatic thoughts, highlighting the rigor, at the same time, it also existed the problems which included various contents, the demand of the teaching highly, the difficulties of students' learning deeply, readability of textbooks poorly. The curricular reform reflected the educational reforms in china, and used a large quantities of the advanced theories in courses and the educational concepts from the foreign countries for reference at the end of 1990s, then solid geometry made the corresponding adjustments which included retaining the essences and deleting the branches, highlighting the essences, considering the cognitive laws of the students ,reducing the difficulties of the learning, paying attention to the penetration of the algorithm, but due to deleting the contents too much, it reduced the students' intellective level. Entering the 21st century, the new curriculum embodies the constructivism more and the notion—"learners-oriented",Solid geometry has adjusted the curricular contents moderately , it embodies humanistic care, and emphasizes the cultivation of the ability in inquisition, and highlights the application of the information technology and algorithm thoughts in solid geometry, and enhances the readability of textbooks . Through the analysis of textbooks and the characteristic of the curriculum, the article reflects the transitions of the educational concepts in math in the past of 30 years: keeping the educational traditions——"mathematics is the tool to training the thinking",and"developing students' abilities in math all-round", at the same time ,mathematical education emphasizes the conversion from knowledge-oriented to learner-oriented , from emphasizing internal integrity and independence of the discipline to emphasizing the mathematical unity and inner link, from emphasizing the value of math as the tool to emphasizing the multiple value.By the reflection to the evolution of solid geometry in high school, the article has concluded the revelations to the current reform: first of all, a comprehensive understanding to the value of the mathematical education: paying attention to"mathematics is the gymnastics of training thought", and revealing the values of mathematical culture, mathematical application and rational spirit. Secondly, curricular reform should establish the idea of mathematical education——"learners-oriented"; and curricular reform is not"revolutionary", but it has inheritances and abandonments, and it is a gradual process; Moreover curriculum reform should consider various factors comprehensively, and coordinate the relationships and the contradictions.
