Research And Reflection On The Solution Of Solid Geometry In College Entrance Examination

Stereoscopic geometry is one of the important contents of high school mathematics knowledge.The new curriculum standard for senior high school mathematics(Experiment)states that students should improve their mathematics ability whit effort,enthusiasm and learning methods of daring to explore new knowledge.In such a large,three-dimensional geometry of this part of knowledge as to cultivate students' knowledge ability,figure drawing,flexible spatial imagination ability,logical reasoning ability and carrier learning analogy thought is very important.In learning mathematics at ordinary times,in addition to enriching their cognitive structure and strengthen the core literacy of mathematics,mathematics college entrance examination is one of the most important parts,new thoughts and new concepts can reflect the college entrance examination mathematics curriculum design and mathematics curriculum content directly,at the same time,college entrance examination is judged whether the students acquire mathematical knowledge and even get what the source of knowledge.In the college entrance examination,the degree of difficulty and quality of the test questions will directly affect the degree and level of the whole course of Mathematics.So that,the college entrance examination is an important factor that affect the future trend of mathematics education and teaching.And from the perspective of the college entrance examination mathematics examination paper structure,mathematics(the new curriculum volume)solid geometry problems and there are three types: fill in the blanks and answer,choice,and solid geometry in Senior high school to answer questions the rule of the annual problem.And every year the three-dimensional geometry of the solution is divided into two questions,a total of 12 point.Therefore,most of the students in the space of three-dimensional geometry of this part of the knowledge of learning more difficult,in the space to imagine,computing,logical reasoning and other aspects prone to more of the more Problems,especially in dealing with the college entrance examination three-dimensional geometric answer questions more difficult,the score was significantly lower.Therefore,it is necessary to combine over the years(2007-2016)college entrance examination solid geometry answer questions,from the teaching aspects of thinking and research.The first part of the thesis discusses the importance of solid geometry in senior high school mathematics knowledge in the sector and an important position.second part consulted about the three-dimensional geometry of the literature,analyze and research status of solid geometry questions.then the author identifies some problems in the research and the research direction in third,part of a high school science students in Shijiazhuang city about solid geometry knowledge system learning were investigated by questionnaire,and the use of frequency statistics on the results of the survey,to understand students' learning and the teachers in solid geometry exists in the educational fields asked from Problems,and these problems the author made the corresponding summary.the fourth part according to the results of the questionnaire,the author of the recent ten years(2007-2016)the national mathematics curriculum volume(Science)in solid geometry questions to conduct a detailed statistical analysis,and analyzes the common knowledge in the college entrance examination in the three-dimensional geometry of questions with the commonly used method,after discuss the national new curriculum volume(Science)solid geometry proposition trend to answer questions in the college entrance examination in the future.then according to the above analysis to put forward some teaching suggestions related to teachers in the teaching work.Based on the results above,put forward the following strategies:(1)to deepen the understanding of concepts and propositions,training rigorous reasoning ability.(2)pay attention to explanation and practice method,master the methods to solve the essence.(3)enhance the transformation of students problem-solving ideas,reveal the inherent relations of knowledge.(4)the rational use of space vector method that is the key to establish the coordinate system.(5)the cultivation of students' rigorous logical thinking,training students' ability of solving problems.(6)improve the students' mathematical literacy core,enhance the sense of innovation.Finally the author of some summary and reflection of this thesis,summarizes the main content of the paper,in the course of this study is insufficient the author places and in some future.I hope this research can provide teachers provide some reliable useful reference in the future teaching practice.
