A Content Distribution Comparative Research To Four Major Domains Of Three Sets Of Junior Middle School Mathematics Textbooks

Since 2001, China began to carry out basic education curriculum reform, one of this new curriculum reform's key was "the program of instruction" turned the past "the curriculum standard", Teaching material's system has also had the very big change, turned one kind of standard necessary many kinds of teaching material from past standard necessary one kind of teaching material. Junior middle school textbooks in many new situations, various materials on the "curriculum standards" understand quite different. In these textbooks, Beijing Normal University Publishing House version, East China Normal University Publishing House version and the People's Education Publishing House version. These three materials is the most representative materials. For these three studies textbooks and it is very theoretical and practical significance.In the reform of the junior middle school mathematics curriculum were divided into four areas: Number and Algebra, Space and graphics, Statistics and Probability, Practice and integrated application. This article is to say that in front of the three textbooks for the object, three textbooks on the four fields of study, through research, we found that:First, in the "the number of algebra" area, three junior middle school textbooks with the "curriculum standards" is the same.Second, in the "Space and graphics" area, three junior middle school textbooks with the same proportion, but in some aspects of the presentation of the structure, there are obvious difference.Third, in the field of statistics and probability, three junior middle school textbooks vary greatly, the East China Normal University Press textbook in addressing the problem of the calculation of probability, with the "curriculum standards" quite different.Fourth, in the field of practice and an application, and three junior middle school textbooks have made some reforms, and the contents do not show the same respect, but because no previously not done so, are right.In view of the above study conclusion, the authors make the following main observations and recommendations:On the one hand, improve the author's textbook "curriculum standards" understanding, On the other hand perfect "curriculum standards" itself, And hope that the author can consider user's opinion, Reasonable textbook ratio arrangement may be considered at the same time. There is no standard and theory available for the textbooks' content distribution research, we hope by this article a real exploration can be realized.
