A Comparative Study Of The Textbooks Of Junior Middle School

After the Mathematics Curriculum Standard of Compulsory Education(2011) has been promulgated, various of textbooks have carried out a new round of amendments, the equation as the core content of compulsory education in mathematics teaching has important research value, in order to better grasp content of the new textbook equation,in this study, the People’s Education Press, Beijing Normal University Press, Jiangsu Science and Technology Press, the three versions of textbooks for the study of equations and related content. Through the systematic study of linear equation with one unknown, system of linear equation with two unknowns, fractional equation, quadratic equation with one unknown, intended to highlight the equation holistic learning in junior high school. The study compares the research mainly from the architecture of equation, the presentation of equation and the characteristics of textbook three methods of teaching materials, conclusions of this research are as follows:Study equation for architecture, mainly from the system and structural equation equation launched two angles. First, the equation system of the three versions of textbooks is similar to each other. It’s all in accordance with linear equation with one unknown, system of linear equation with two unknowns, fractional equation, quadratic equation with one unknown, order to start learning, the order of system of linear equation with two unknowns, fractional equation, and linear function three versions are slightly different, and each part of the lesson arrangements are different; secondly, the structure of the equation by comparing the transverse and longitudinal study found that three versions of the content of the presentation materials of the equation are using a spiral structure, the overall structure is highly similar, each part of the equation is broadly divided into understanding the contents of the title equation model, solving equations and three categories of application equation, basically followed the "problem situation â†'establish equation modelâ†' solving, application and expansion "mode, all kinds of equation design ideas are basically the same, on the one hand reflects the consistency of their own design, on the other hand, also reflects a certain degree of convergence on existing materials.The presentation of equation, start mainly from the textbook style, column setting, issue material the three angles.First, from the perspective of teaching style, the most abundant form of the People’s Education Press textbook style structure, the Jiangsu Science and Technology Press second, followed by the Beijing Normal University Press is relatively simple; secondly, from the column design perspective, the most abundant form of the Jiangsu Science and Technology Press textbook column settings the most abundant form, but functional overlap, the People’s Education Press setting than the rich, the lack of operating activity type column, the North Division version column set is relatively simple; Finally, from the perspective of textbook chapters before the problem analysis, the number of questions and there are differences in background. For the textbook examples and exercises are also significant differences in material selection.Research on the characteristics of materials, mainly analyzes the various versions of textbooks for the penetration of mathematical thinking, which contains the equation of thought, the idea of combination of number and shape, classification thinking, as well as substitution, mathematical method to reduce time, elimination, etc. Each version of the textbook is designed with certain characteristics.
