Middle School Mathematics Vector Teaching Research

The new-round mathematics curriculum reform, from the ideas, contents and implementations, has been changed greatly, Among them, "the vector mathematics" —which developed and applied at the turn of the 19th century to the 20th, with its wide application in modern mathematics. Physics, Engineering, and Spatial matter structure, has been noticed greatly. Further more, it has formed a mathematics system with a set of fine operation passing methods. Today it has been brought into the basic mathematics curriculum in middle school and became a flashpoint in this new mathematics curriculum reform.In many countries, vector as a basic course content, has already been included in the mathematics course for middle school students. However, in our country as it just has been applied in the middle school mathematics curriculum, the study of vector is still in its start stage. And the research of its is even weaker. The vector is one of the most basic concepts in modern mathematics, it has a "dual status"—"Algebra form "and "geometry form". It is a bridge to link up the contents of Geometry. Algebra and Trigonometry. It has rich actual background and widespread education value, including cultural and educational value, intelligent and educational value, practical and applied value. Vector value determines that it is very important to do its teaching well.It is necessary to bring vector into middle school mathematics course. However, how a teacher advances his vector teaching under a new education idea is what I want to go further in this paper attentively. During the research , the writer uses documental method, and describes the relative data, and also uses investigation method to survey the questions about the vector in the middle school teaching, and experimental method to realizes the strategies of teaching, this research enhances the experimental validity and reliability. I fully use modern educational concepts in my teaching practice, including documentation, investigation, combination the operation with study In this process, I study it carefully, design it accurately, put it into practice boldly and think it over. I give many suggestions on how to advance vector teaching in this paper. As far as we know, vector concepts and its operation are the key points of teaching. In the teaching process , we should pay attention to its background and introduction ,and improve our teaching by using geometry mapping skills of it s, At the same time, I use new curriculum reform concepts properly: "grouping ,cooperation and research" in my teaching in order to bring the initiative of students into main body ,and embody the principle that students should study actively .With this teaching method, we should strengthen the relations between vector and its application, attach the importance to infiltrate mathematics ideas and methods into it. Especially, we should know that vector analysis plays a very important role at the core in vector teaching.
