The Compilation Of Examples Of Mathematics Textbooks For Junior Middle School Published By People Edition And The North Edition Characteristics Of Comparative Study

With the advancement of the new curriculum reform of mathematics,teaching materials as the carrier of the curriculum plays an important role in teaching and studying.As one of the three organic components of the junior middle school mathematics textbook(text,examples,exercises),it reflects the application of mathematical concepts and laws.As a link to linking knowledge,skills and methods of thought,it is important to transform the knowledge of teaching materials into students abilities.Its writing characteristics directly affect the quality of teaching materials also affect the quality of mathematics classroom teaching,the writing characteristics occupy the prominent position in teaching materials.In this paper,we study the characteristics of some examples of "number and algebra" of junior middle school mathematics teaching materials in two versions of our country,and divide the research questions into three points: 1.how to build junior high school "number and algebra" examples of text analysis framework,that is,from which category analysis of textbooks in the preparation of examples of examples? 2.in the textbook,the two versions of the examples prepared in the framework of what kind of features? 3.the analysis of the results and the preparation of new materials for junior high school students to make recommendations and teachers use the textbook example of the proposal.First,construct the example text analysis framework,including the following six aspects:1.the case contains the type of context;2.examples include the problem-solving stage;3.examples of openness;4.examples of the knowledge area;5.examples of content contained in the type;6.examples of mathematical ideas.Secondly,the text is encoded,statistically and analyzed by means of literature,content analysis,comparative research,statistical analysis and other research methods.Two versions of the textbook examples of the preparation features: 1.pay attention to pure mathematical problem situation(the proportion of up to 78.18%).Explain the teaching examples of the problem set more attention to the basic knowledge of mathematics;2.pay attention to proposition type example design(52.73%),concerned about the students on the formula,the law and theorem of the direct application;3.in line with the requirements of the new curriculum,the number of content and more(61.82%);4.examples contain rich mathematical ideas and methods.Some examples include only one,and some with a variety of mathematical ideas.Accordingly,recommendations are made from two aspects.1.the recommendations to the junior high school mathematics textbook preparation :(1)highlight the example of the preparation of personalized;(2)increasing the proportion of examples of social life and other disciplines as problem situations;(3)increasing the proportion of multiple stages to solve the problem;(4)increase the proportion of various types of open examples.2.teachers use the textbook example of the proposal:(1)to create a problem situation,contact students’ "mathematical reality";(2)to set up open issues,play the main body of students;(3)to inspire students to learn mathematics,perception of mathematical ideas and methods.The main two directions of the follow-up study: 1.the contents of other versions of the textbook research;2.in addition to the other content of the study in "number and algebra".
