The Comparative Of Triangle In Junior Middle School Mathematics Textbooks Between China And America

This article selects Zhe Jiang to teach the version junior middle school mathematical teaching material and Oxford University Press in America junior middle school mathematical textbooks,from the selection and arrangement order and the content difficulty two aspects content,through the literature analysis, statistical analysis and other research techniques, has conducted the comparative study to the triangle content in textbooks.Chinese textbooks in the learning of new knowledge at the same time pay attention to the expansion of the subsequent content and extension, and the teaching material more attention paid to review the old knowledge. Material in China, the United States are in accordance with the special to general logical sequence. The second Chinese teaching material in terms of the breadth and depth of content of the triangle are slightly higher in America; In the aspect of the difficulty of the sample,the Chinese teaching material in reasoning level is lower than the United States, in the aspect of operation level and the United States teaching material close to, but on the background of knowledge level, and to explore the levels are higher than the United States.Finally, according to the analysis of the results obtained the following enlightenment and suggestions: to increase the color and interesting textbooks, so as to improve the enthusiasm of studentslearning. Before the new class, add the old knowledge related to this class and increase the connection of knowledge. To provide more opportunities for students to practice in the classroom, you can add a special section to allow students to draw the contents of the triangle. Appropriate to increase the level of reasoning examples, pay more attention to the innovation of thinking.
