The New Curriculum Concept High School Solid Geometry, The Research And Practice Of Teaching

Since the new course reform, the three-dimensional geometry of content is divided into compulsory and optional content into the new high school textbooks, it is to develop students ability of geometric intuition,intuition thinking ability, logical reasoning ability abstract logical ability and play a decisive role, while using three vector method to solve the problem in solid geometry and provides a new angle of view, In the new curriculum reform background, we investigated how solid geometry teaching?This research mainly adopts questionnaire survey method, interview method, classroom practice of Wuhan University attached middle school teachers and students were surveyed, using literature research method, mathematical learning theory, educational psychology of mathematics, mathematics teaching theory, curriculum and teaching theory as the basis, to theoretical research, on the basis of practice research. Focus on the new curriculum reform after the solid geometry teaching and learning problems, and puts forward some suggestions. This thesis is divided into four parts to do research:The first part is to bring forward the question. This part mainly expounds solid geometry knowledge in high school mathematics content in the status and role, three-dimensional geometry education value and significance and the important position in developing students’ability.The second part studies under the new curriculum standards, the three-dimensional geometry of the content and teaching theory. From geometry, domestic and foreign textbooks in the three-dimensional geometry content setting, the old and the new textbooks in the solid geometry content comparison three aspects to carry on the elaboration, summarized. On this foundation, it is clear in the teaching direction of the solid geometry of the new curriculum.The third part studies the thinking under the new course standard in solid geometry teaching. Using a combination of theory and practice way, conducted an investigation and theoretical research. From the teacher to the using of new teaching materials, solid geometry and mathematical thinking, the creation of the problem situation, the vector method of introducing four respects undertook studying, we analyze the problem of existence, which caused the thinking. As the new curriculum teacher, how should we do in the area of effective teaching.The fourth part is solid geometry teaching practice research. Through a typical case in front under the guidance of the theory, we do the practice teaching and study on the feasibility of teaching method.
