Analysis Of The Three-dimensional Geometry Questions In Mathematics Exam Papers Of The College Entrance Examination And Research Of The Teaching Strategy

Geometry is a spatial form of scientific research, and now still continues with the increasing of people’s awareness. The high school geometry is the most basic of this discipline and the easiest part which is also the foundation for further study and research. And the three-dimensional geometry in high school is the most important to learn,it is very beneficial to train and develop students’ ability of space imagination,reasoning ability,the ability to use graphic language and geometric intuitive ability to communicate, Improving students’ mathematical thinking ability is very useful.And it also accounted for a large proportion in college entrance examination scores. Therefore it is a common concern of many educators topic about the teacher how to tell the students about the knowledge of three-dimensional geometry and the students how to achieve good results in the entrance.Moreover high school,there are differences between arts and science students in mathematics.Thus this paper as an example of science,considers, high school mathematics textbook, ”mathematics curriculum standards”, near the entrance Mathematical analysis of two science questions and other information as the basis,to explore three-dimensional geometry of high school teaching strategies.Firstly, This paper discusses the statues of three-dimensional geometry in high school mathematics students and surveyed students,problems occurring in the learning process. Secondly, it determines its research direction by consulting information and analyzing current situation.Thirdly, investigating the learning situation of three-dimensional geometry in high school is to understand some of the issues in the three-dimensional geometry of students learning and teachers’ teaching.According to the analysis of 4aspects(number, scores, test knowledge, examine ability)of the College Entrance Examination Paper in2013,2014 each province,it get entrance exam type and solutions as well as some learning recommendations. Lastly combining with theoretical knowledge concerned, it makes the following teaching strategies:(a)Using objects and information technology to improve handing ability and to improve the ability of space imagination.(b)Paying more attention to basic knowledge during teaching,guidingstudents to integrate knowledge,forming their own knowledge networks.(c)Focusing on problem-solving analysis, leading students to give more solutions and reflect learning,improving the quality of thinking.(d)Infiltrating the mathematical culture to improve the students mathematics accomplishment.Hope to help students have a better learning on solid geometry, meanwhile provide a useful reference for teachers,teaching practice.
