浅析向量在高中数学中的角色（Analysis of the role of vectors in high school mathematics） Analysis of the role of vectors in high school mathematics Mathematics teacher of yangjiang farm middle school, qiongli county, hainan province: even huihua The 2009-4-14 In high school mathematics new curriculum, the compulsory 2 learning space geometry, dot, line, surface, then the required four second learn plane vector, lets the student have a preliminary understanding to vector, to take 2-2 space vectors and solid geometry before learned the content of the organic unifies in together, using vector space geometry problems clear, process simple, unexpected magic effect, better than in the past conventional method to solve the problem of space geometry is the more deep the understanding of the novel. This fully reveals the importance of the method. If we can pay attention to the teaching of vector, we can guide students to expand their thinking and reduce the burden. The flat vector is a new addition to high school math and a bright spot in the new college entrance exam. Knowledge vector, vector view in many branch of mathematics, physics and other disciplines has been widely used, it has the algebra form and the geometry form of double identities, can melt number form into an organic whole, with the middle school mathematics teaching content of many of the main comprehensive knowledge, create knowledge. In high school mathematics system, space geometry plays a very important position, there are some problems with conventional methods to solve the operation is complicated, often might as well use vector for the shape and the number of conversion, will greatly simplify the process. According to the 2009 exam syllabus, the mathematics subject of the 2008 exam is basically unchanged. This characteristic shows that the national college entrance examination mathematics exam after years of exploration, reform, has been gradually stabilized, forming stable, pay attention to the foundation, outstand
