A Compare Study On The Geometry Knowledge Arrangement Of Mathematics Textbook In Junior Middle School

Mathematics is the national curriculum in primary and secondary schools is a discipline unified words, then the geometry is a part of the unified. Textbooks in the implementation of the curriculum plays a very important role. A country’s level of textbooks in some extent reflects the country’s level of education. In the actual teaching, no textbook both in students’learning still plays an important role in the classroom teaching. Based on the knowledge of junior high school mathematics textbook arrangement as the breakthrough point, the junior high school mathematics textbooks in Chinese PEP and ECNUP and Japanese Kai Lin Museum as the research object, from the dimension for the study of reasoning way of concept and proposition of geometric thinking level and proposition, found the similarities and differences of the 2 countries the 3 versions of textbooks。1 junior middle school mathematics textbook contents, textbooks of the two countries Each has its own merits., Japanese textbooks to Chinese in solid geometry textbook, content involves many. And our country in plane geometry part of either the number of concepts and propositions, are more than 2 in Japan; geometry thinking level, the three versions of textbooks in accordance with the Vancil theory of geometric thinking level. Our country is higher than that of Japanese textbooks in junior high school textbooks, especially the 7 grade. Two versions of Chinese textbooks, the geometric thinking level of ECNUP edition textbook is obviously higher than that of PEP edition. The textbook knowledge of geometry thinking level grade span are larger; reasoning in proposition 3 is introduced, the three versions of textbooks have paid attention to plausible reasoning and deductive reasoning. China is Japan’s textbook teaching department pay more attention to plausible reasoning. Compared with the Japanese textbooks, textbooks in China pay more attention to the introduction of geometry as a way; 4 in the geometry arrangement system, the Japanese textbook pay more attention to the educational value in geometry, textbooks in China pay more attention to the knowledge structure geometry; the 5 generation of concept learning, textbooks in China pay more attention to the concept of Japanese textbooks pay more attention to the concept of assimilation.Finally put forward the junior middle school mathematics textbook "graphics and geometry" in the field of some suggestions for the arrangement of knowledge:pay more attention to cultivate students’ ability of space imagination; in the curriculum, should pay attention to the selection and development of Grade 8 of the content; in the presentation of concepts and propositions, the focus should be on the geometric characteristics, the concept itself the structure of knowledge and students’thinking features, to prevent too; the concept is present, should pay attention to convergence problems in middle and primary school; in the geometric reasoning, reasoning in the form of deductive inference and plausible reasoning fully reflected, should focus on students’formation of deductive reasoning method, students can understand the proving of geometry textbooks, can independently that does not mean the students.
