Stereoscopic geometry is an important part of high school mathematics. It is based on the geometric aspect of junior middle school, and further studies the relationship between spatial point, line and surface. Stereo geometry is the focus of high school mathematics and difficult, but also the contents of the college entrance examination must pass the calendar year. However, from the actual learning situation of students that students on the three-dimensional geometry of this part of the content is not ideal, mainly in the three-dimensional geometry of the study, students are often faced with specific problems feel helpless. How to understand the basic concepts and theorems involved in the three-dimensional geometry; how to understand the ability of the graphics, geometric intuition and spatial imagination, logical reasoning ability, the students in the three-dimensional geometry of the study of what What obstacles are in urgent need of research.The text through questionnaire and test in the form of a middle school in Lu'an city high school 206 students from learning solid geometry attitude, students mastery of the basic knowledge of solid geometry, the students of graphics research on students' ability to grasp the geometric language ability etc., found that students learning disabilities are divided into solid geometry three aspects: first, understanding obstacles in learning solid geometry in the sketch, the definitions and theorems of memory and understanding,thinking and spatial imagination judgment and other obstacles; second, operation: in the application of knowledge proof methods and ideas, and drawing theorem and methodOther aspects of the disorder; third, affective disorder: emotion is the human heart to hold things outside positive or negative, reflecting positive or negative attitude,including attitude, cognition, emotion and behavior tendency of the three aspects of the disorder.According to the above analysis of the obstacles of the causes of these obstacles,and then put forward the corresponding countermeasures. First, barriers, consolidating basic knowledge and promote students' understanding of knowledge; strengthen the linkage of junior high school; specification language teaching, improve math skills; to understand their existing cognitive structure and knowledge level of experience. Second,operation obstacles: pay attention to the teaching of mathematical thinking; gradually improve students' spatial ability; training of mathematics reading ability attention; third,affective disorder: inspire students thirst for knowledge; to help students clear learning objectives and plans; harmonious relationship between teachers and students.
