The Survey And Analysis Of The Developing Circumstances Of Junior Middle School Students' Space Notion

Geometry and Space Notion are an important component of mathematics education, which can reflect our physical environment and help to foster people's creative ability. Environment in which we live has become a full of rich imagination and creativity of social, so that Space Notion is becoming an important content of the stage of Compulsory Education.The view part is important learning resource to culture students'spatial concepts. The purpuse of this paper, is to study the situation on "Graphic Understanding of the Initial" of Junior high school students, analyze their degree of control, make some countermeasures and suggestions and service for developing junior high school students spatial concepts。In this paper, the Beijing region's two junior high school students and teachers as the research object, mathematics curriculum, education theory, curriculum theory, based on "Mathematics curriculum standards" requirements, as measured in the students to master teaching content (mainly includingidentification of three-dimensional graphics, three-dimensional graphical view of the three to start plans, etc.) to form a concept of space (including the knowledge map capabilities, spatial imagination skills, etc.), teacher interviews, etc., the use of literature analysis, content analysis, surveys, comparative research methods, etc.Expand investigations and studies. Through surveys and analysis, to identify Beijing this mathematical view of two junior high students in the initial part of the problem The reason put forward some countermeasures and suggestions for improvement.Through analysis and research, This paper argues that students in the two junior high schools exist in the following questions: Students of different sexes have different learning geometry when the acceptability, to be divided; Most of the students in numeracy maps carefully observe the graph is not enough, consider the problem is not comprehensive, students should be further improved graphics cognitive abilities; key part in knowledge3 view, expand diagram, a good mastery of animation, but the three-view drawing of the selection and there are still some issues, such as less capable graphics logo, name is not accurate; space of the imagination, examining the problem is not comprehensive, imagine the poor, and can not imagine in a short time a complete and accurate graphics.In response to these problems, the authors first-line teachers in the school work interviews, this paper think we should take the following measures:For the students of different genders, it is necessary to adopt a different training method. Treatment of girls, mainly to enhance the expansion of thinking, response capabilities, enhance their knowledge and mastery of the absorption capacity; and treatment of boys, mainly from doing the theme of accuracy, rigor of thinking, answer the steady-state starttrain boys seriously, a careful examination capabilities; designed to improve students through teaching a variety of space capabilities, so that students perceive, experience in the creation of space concepts; the use of modern educational technology to students of space and deepened their understanding and impression; in extra-curriculartraining to enhance students knowledge map, spatial imagination, strict demands on students, practice makes perfect.
