The Use Of "Shuoxingjiege Thought Of" Guiding Junior Teaching And Research And Lesson Function Analysis

Engels said "The mathematics is the science which study the magnitude relationship and space format". Interpretation for "compulsory education mathematics curriculum standards (2011)", found that many important mathematical content and concept also have the characteristics of number and shape,which required to proceed from these two areas, understand and grasp the meaning of the essence, this is the " combination of number and shapes"."The combination of number and form," is an important mathematical ideas, is also an important study on the mathematical method. Thus, some of the theorists and teachers improve the thinking ability for" combination of number and shapes " as a necessary way for students to develop good mathematical thinking. In the actual teaching, the author mainly through this idea to guide students to analyze the function and graph, and to get the effectiveness. This article is divided into six chapters to elaborate the role of " combination of number and shapes " in the function of teaching for the junior high school:The chapter Ⅰ introduction, to introduce the topic background of research and the definition of main concepts, and research methods; Chapter Ⅱ the subject status quo research, introduce The status quo of foreign and domestic" combination of number and shapes"; ChapterⅢ the teaching current situation and thinking of junior high school; Chapter Ⅳ the teaching principles and measures" combination of number and shapes "; Chapter Ⅴ task analysis for the ideological training of" combination of number and shapes " of junior high school function teaching, by means of the concept guidance, exercises course, and subject course, training students for the use of the " combination of number and shapes ", to guide students solve the function and graph issue vividly and concisely. Thesis by teaching practices, from "help","solution","conversion" three point of argument "number shape Union" steering function study in junior middle school, you can make complex questions simple, abstract problem materializes, optimize students’cognitive approaches, improve students mathematical literacy. Chapter VI conclusions and issues to be studied.
