A Comparative Study Of The Basic Elementary Functions (Ⅰ) About "Beijing Normal University Version" And "People’s Education Version (A)"

The foundation education course reform outline (try ouline) and ordinary high school mathematics curriculum standard (experiment) encourage diversified writing textbooks, And at that time our country emerges out multiple versions of the mathematics teaching textbooks. With the diversification of textbooks, textbooks compare research is becoming more and more importation.In this paper, I take "Beijing normal university version" and the " People’s education version (A)" the basic function of junior high school (I) as the research object,to adopt the literature method, comparison analysis and statistic analysis method, set up and the content of the two versions textbooks difficultly to compare:(ONE) By comparing the contents of the two versions of discovery:(1) In the aspects of system structure:"Beijing normal university version" of the knowledge arrangement detail, pay attention to the logic of knowledge development and primary and high cohesion, pay more attention to the basis of the implementation of mathematics curriculum," People’s education version (A)" choreography is relatively simple, pay attention to knowledge system of systematic and integrity, consciousness of students’logical thinking is higher.(2) Knowledge on presentation:"Beijing normal university version" textbook on the introduction of the concept of using the spiral arrangement way, structure is compact, pay more attention to the continuity of the students’basic and logic,Directory to arrange specific;Chapter first introduction to highlight the status and role of this chapter;Setting up more novel, variety forms, pay attention to training students’ability to understand and hands-on practice;" People’s education version (A)" textbook in the mode of the introduction of the concept, more used to explore the way of thinking, pay attention to cultivate students thinking to explore the ability;Directory Settings are short;First chapter introduction instance is rich, pay attention to highlight the knowledge before and after contact as well as the method of mathematical thinking;Set column is relatively simple, pay attention to the development of the exploration and thinking ability of students.(TWO) Through the two versions the difficulty the comparison found:(1) On the breadth and depth of content:the content of the "main" breadth and depth are slightly higher than the "taught A" version, but the overall difference;Depth of the concept of average lies between1and2, compared with the high students’cognitive level;(2) On the difficulty of the problem sets comprehensive aspects:"Beijing normal university version" is the number of problem sets "taught A" version1.86times;Problem sets comprehensive difficulty is "taught A" version1.87times;(3) On the teaching material difficulty:"Beijing normal university version teaching material" the difficulty for "taught A version of the teaching material of1.74times.Comparative study found that the two versions have distinguishing feature each, therefore in the process of teaching material to write perfect can be targeted to learn from each other, complement each other.In terms of teaching material selection, different areas, different schools should be on the basis of fully understand the characteristics of the teaching material of expressing ideas, combined with the actual situation of students reasonable carefully select the teaching material, to translate the choice of teaching material to a specific area, the school and class;At the same time, teachers can be based on a version of the teaching material, at the same time reference other versions of the teaching material, using for reference the other teaching materials, complement each other, eclecticism, making the teaching material to better serve the education teaching activities.
