Vector Teaching Study In Middle School Mathematics

With the rapid development of science and technology, particularly Computer science, the original curricular and model of mathematics have been challenged, which give rise to worldwide reform of mathematics Curriculum. In order to build a new system of basic education for 21st century, experimental textbooks have been firstly used in the province of Jiangxi and Shanxi, also the city of Tianjirig in 1998.Vector which is the weak point of mathematical course in our country is contained in the mathematical curricular. Now, Vector Algedra is one of the core contents in middle school's mathematical course all over the world. Vector involved in class of middle school is necessary ,because dual indenticy (calgebra and geometry) of vector provide a direct basis for the trasition and connect primary mathematics and higher mathematics. At the same time, the concept of vector combined with the development of physics helps students to recongnize the power of maths ,which will enhance their interests. It's a powerful tool to improve geometry in a middle school .Vector involved in the class of middle school is feasible for students have already learned the basic knowledge of coodinats, and leathers have rich teaching experiences using modern educational technology, make learning vector easier.The author, with careful analysis, elaborate designing, bold practicing, based in modern educational theory and technology in teaching vector, provides practical teaching cases and methods, in order to make vector teaching effectively and fluently.The author reflects carefully after teaching, offers some advice on training before teaching vector. Middle school teachers should firstly study "Vector algebra and vector analysis" systematically, by which not only they can comprehend profoundly the relationship between vector and other mathematical structure,but also see combination of vector and math with an developing eye to appropriate dynamical curriculum standard.
