The Proposition Analysis Of Vector Examination For College Entrance And Vector Teaching Strategies Study

Vector set "number" and "shape" in one,not only combine the different knowledge points within the discipline,also have extensive application between the discipline and the discipline,in our life,the vector is also with shape.As a mathematical tool,vector has been widely used.It builds a bridge between geometry and algebra.It links plane geometry,solid geometry,algebra and trigonometry.It gives us a new way to solve problems and exercises the students 'ability to apply knowledge synthetically.The vector of learning not only expands the operation of numbers and provides new ideas for solving geometry problems,but also lays a solid foundation for us to further study higher education knowledge.The college entrance examination is a window for selecting talents.The analysis of the college entrance examination questions can make us better grasp the requirements and standards of vector chapters in the new "curriculum standard",which is conducive to establishing teaching goals and improving teaching strategies.Investigating students 'problems in learning vectors is helpful for us to reflect on our teaching shortcomings and find the correct methods and strategies.In this paper,the history,understanding and value of vector in high school are introduced,and the present research situation of vector in college entrance examination is analyzed.Secondly,we selected the national,Beijing,Guangdong,Jiangsu and 15 sets of test papers in the past three years.Then,the problems in the course of learning vector and in the course of problem making are investigated and analyzed by questionnaire.Finally,some high school vector teaching strategies are given.Through analysis and summary,some conclusions and teaching strategies are drawn and shown as follows:1.The vector proposition analysis of the university entrance examination: the high examination question is "live" new class standard,the proposition score and proportion of the vector part tends to be stable,and has the upward trend,the topic type is more diverse,the knowledge point that examines more.The comprehensive difficulty of vector topics tends to be stable,focusing on the examination of knowledge,logical reasoning and application;2.Problems of students in learning and exercising:Problems of students in learning and exercising: the students have less interest in learning,the mechanization of learning methods,the confusion of concepts,the poor sense of vector application,and the degree of mastery of high test points.3.High school vector teaching strategy: change teaching mode,permeate the idea of combination of numbers,strengthen spatial concept,understand vector essence,comb the vector related knowledge points,take students as the main body,train the ability of independent learning.
