A Comparative Study Of The "Practical Mathematics Wide Angle" And The Qingdao Version Of "Wisdom Square"

Since the reform of the new curriculum,in order to response the educational policy of textbook written in a variety,the version of elementary school mathematics textbooks are becoming increasingly diverse,also according to the new curriculum standards,the content of textbooks are becoming constantly plentiful,the content of elementary school mathematics textbooks are more and more suiting the development needs of students? physical and mental.According to the compiling ideas of the new curriculum,the "wisdom Square" of QPH and the "Mathematics Wide-angle" of PEP both are new topics that aim to permeate mathematical thinking.I select "Mathematics Wide-angle" 0f PEP and the "Wisdom Square" of QPH as the research object, selecting the compiling recommendations 0f Compulsory Education Mathematics Curriculum Standards(2011 edition) as guideline, using the method 0f literature, comparison, content analysis and interview to analyze the written characteristic about material selection, content arrangement and presentation of "Mathematics wide-angle" and "Square wisdom", so as to find the similarities and differences, the advantages and deficiencies in "Mathematics wide-angle" and "Square wisdom" writing,finally provide some suggestions for writing and teaching.Through literature analysis, the author found that the existing comparative study of the textbooks at home and abroad are mostly about the static text analysis of different versions of textbooks, the lack of dynamic survey of the use of textbooks. Selecting "Mathematics wide-angle" and "Square wisdom" to compare, there are helping to the further understanding of the different versions of textbooks of mathematics thinking, writing characteristic, also provide a theoretical reference for the teachers.After the analysis of "the wisdom of the square" and "mathematics wide-angle" material, the author found that "mathematics wide-angle" and "wisdom square" source of material for the use of mathematical activities, content, the selection of visual image, in line with the law of physical and mental development of children. Material selection is mainly based on the tendency of neutral, lack of rural subjects. The author of "the wisdom of the square" and "mathematics wide-angle" content list sorting found two parts are the spiral structure of the arrangement of the contents, the gradual infiltration mathematical thought; in the order of arrangement, "mathematics wide-angle" and wisdom square in students in different periods of the arrangement of different mathematical ideas. The first section of mathematics thought foundation of intuitive, the second period considering the improvement of the level of physical and mental development of the students, mathematics thinking abstraction has improved.In the presentation, the author found that "mathematics wide-angle" and "the wisdom of the square" in the column settings, examples, exercises, illustrations and verbal presentation on each with its own characteristics. "Mathematics wide-angle" column are varied and pay attention to the penetration of mathematical culture, illustrations, material selection, examples and exercises of the scene present close to the reality of the students, the speech has the students with the characteristics of expression. Examples and exercises, speech presentation are in accord with the laws of the development of children, examples and exercises design in consideration of recent theories of development zones based on challenging, rich interest and development of examples of gripping design mathematical thinking, problem solving process is presented to fully mobilize the enthusiasm of the students' initiative. Among them, the "mathematical wide-angle" exercises designed to fully reflect the level and openness, can fully mobilize children to think.On the basis of static text analysis, the author selects a primary school in Wei Fang City, Jinan City, a primary school mathematics teachers in each of the 5 to interview. The interviews with teachers help us to further understand the characteristic of " wisdom square " and " mathematics wide-angle " in teaching use, then put forward some suggestions for writing and teaching.
