"People’s Education Version" And "Beijing Normal University Version" A Comparative Study Of Junior Middle School Mathematics Teaching Material Content Of The Triangle

According to the full-time compulsory education mathematics curriculum standard (experiment draft) more than a guiding ideology, all over the country at that time has launched a number of different versions of the mathematics teaching material, these versions have distinguishing feature each, for the vast numberof mathematical education workers left a broad thinking space.Based on "People’s education version" and "Bijing normal university version" junior middle school mathematics teaching material of the triangle as the research object, use the literature material method, comparative study method and content analysis method, the difficulty of the teaching material content Settings in the two versions of textbooks and teaching materials on the basis of the comparison:by comparing the content of the two versions of textbooks set found:In the aspects of system structure, " People’s education version " textbook knowledge of layout more compact, focuses on the consistency and integrity of knowledge; "Beijing normal university version of the textbook knowledge arrangement detail, pay attention to the students’ cognitive level; In figure configuration:" People’s education version " the selection of textbook illustrations more life physical figure, pay attention to the reality and students; "Beijing normal university version" textbooks used a lot of decorative pictures to beautify the teaching material, but also easy to distract students’ attention; On problem sets:"Beijing normal university version" material significantly greater than the number of problem sets " People’s education version ", but the two versions of textbooks problem sets for the configuration of class is moderate. And, on the problem sets type two versions are for low proportion of objective questions, prove that topic, the short-answer questions dominated, attaches great importance to the construction problem, problem sets such some characteristics such as close to the reality,based on the difficulty of two versions of teaching materials is found:Degree of difficulty of teaching material "Beijing normal university version" is 1.26 times that of " People’s education version " problem sets its main reason is that the two versions comprehensive difficulty differences.On the breadth and depth of content:the content of the " Beijing normal university version " breadth and depth are slightly higher than that of " People’s education version ", but overall the difference is not big;On the problem sets comprehensive difficulty: "Beijing normal university version" textbook exercises comprehensive difficulty is 1.3 times that of" People’s education version " and exercises the average difficulty is slightly higher than the " People’s education version " teaching material.Comparative study found that each have two versions of textbooks, therefore in the process of compiling textbooks can complement each other, each other effectively and make the version teaching material more scientific; In the teaching, teachers can be based on a version of the teaching material, with the aid of other versions of the teaching material the use of creative at the same time; Can also be aimed at the problems existing in the teaching material, add the corresponding contents and topic, so that the teaching material to better service for the education teaching activities.
