The "Main" And "o ’clock" Comparative Study Of Junior Middle School Mathematics Teaching Material Graphics And Geometric Part

This article is to present the Beijing normal university teaching materials and people’s education press materials of junior middle school mathematics graphics and geometric part of a comparative study, which is divided into five main parts.The first part, this study introduces the background, research status and research methods.The second and third part from the macro and micro two aspects of comparison,The author read about 12 books two sets of teaching materials, and using the Excel software to make charts and statistics figure, and map section structure were analyzed.A macro level, the author divided into "overall features", "chapters" and characteristics of "system" three main aspects;Micro level is divided into "topic type", "narrator", "pictures", "sample", "problem sets" the five main aspects.The fourth part joined with heterogeneous combined with the innovation of the teaching material more,Firstly, three standards of teaching material evaluation,Then select format differences of two content( " polygon angles and ", "the axisymmetric and coordinate change") in classroom activity and observe the student’s class,Then the teaching teachers and some of the students in the interview,According to the teaching case analysis and interview textbooks affect the teaching result, and compared the advantages and disadvantages of two versions of textbooks.The fifth part is summarized, and the main conclusions of this study are:One, the macro level1, Beijing normal university version of some of the more colorful, more detailed content distribution, chapter named lively, close to life, the history of mathematics contained a slightly higher number.Schools are teaching materials reasonable use geometric sketchpad and drawing software, contains number of inquiry-based learning activities than bnu edition textbooks.2, Beijing normal university version of the graphics and geometric part accounts fora large proportion of teaching material,Each book will be in Beijing normal university version graphics and geometry, number and algebra, probability and statistics with three parts,The schools are teaching material of the content of the graphics and geometric part together;Some content main arrangement in grade two different sections, and are arranged in the same section of the same grade.3, Be edition textbooks characteristic columns are "learning objective";Schools are teaching material characteristic columns is "project learning", "mathematical activity", "knowledge structure of this chapter", "in both English and Chinese vocabulary index".Second, the micro level1, Two sets of teaching materials is the introduction of the problem situation.Schools are teaching materials directly give way, way of bnu edition textbooks problem situation and review the introduction way.2, O’clock teaching far more than the total narrator bnu edition textbooks.Schools are teaching basic is stronger.3, Two sets of textbooks are most lifestyle illustration.Bnu edition textbooks significantly greater than the number of illustrations grade seven, eight, nine grade.Schools are teaching materials is the eighth grade in the days of the illustrations,later to grade eight book1&book 2 two sets of teaching material contains the number of illustrations are almost the same.4,Two sets of teaching materials of almost total sample.Are pure mathematics background of most of the sample category.Example reasoning is simple reasoning level accounted for the largest proportion.Examples to explore the level of two levels of the sample is memorization and understanding for a larger proportion.5, Be edition textbooks of problem sets the total number of more than one version of the teaching material,Two sets of teaching materials of after-school exercises number more than half of total number of problem sets.Two sets of teaching material is the base class exercises most.Third, compared with heterogeneous class1, Two versions of the teaching material arrangement and students starting due to development goals and degree, is beneficial to teachers organize the teaching material.2, Two sets of textbooks are fully penetrate the mathematical thought method.3, Two sets of teaching material design colorful, vivid and lively, close to life, can fully arouse the enthusiasm of students, and stimulate students’ thirst for knowledge,conform to the students in the heart of the characteristics and development pattern.4, Students actively building new knowledge from various aspects to strengthen students’ awareness and knowledge process.Fourth, the characteristics of the teaching material The characteristics of main materials:1, The design of the teaching materials, lively can fully mobilize the students’ interest in learning.2, The knowledge of the teaching material content has a fundamental and typicality.3, The teaching material arrangement system embodies a kind of spiral structure.4, Good show in the textbooks and penetrate the mathematical thought and culture valueThe characteristics of the schools are teaching material:1, Are common applicability, the teaching material, conform to the development of most of the students.2, The teaching material is good enough to show the generation process of knowledge, to guide students to actively building new knowledge.3, The teaching material arrangement system both straight line, and there was a spiral, variety.
