Three-dimensional Model Software Blender To Assist Teaching Method Of Three-dimension Geometry

Three-dimension geometry figure teaching,a crutial part in three-dimension geometry teaching,cultivate students' competence in drawing,spatial visualisation and fighure comprehension,which can be better achieved combining multi-media technology.However,the applied effect is not that obvious in practice,making it a must for us to explore the practical use of teaching with the help of mutimedia teaching.It is a necessary trend to combine math class with modern information technology.One of the most significant researches is how to effectively and scitifically apply muti-media teaching aid to optimize math learning.What the author is going to research is application of new software.The essay elaborate in the first chapter what the background and real situations of research into the three-dimensional geometry,and suggest the necessity of application of muti-media in classroom teaching so as to introduce some related softwares of teaching material.The second chapter deals with the analysis,discussion and research of the features and learning obstacles of the three-dimensional geometry.With some research results,the chapter put forward the basic approaches and solutions.Chapter Three includes the survey the author made about 69 math teachers and 111 students in one Anshun senior high,according to pratical classroom teaching in three-view drawing,using SOLO classification to sort different category.The results include that teachers and students approve the effect of modeling in learning;that the Geometer Sketchpad is not widely used in practice;and that students have difficulty in drawing side view,to name just a few.Chapter four is the core of research.According to the results of the research mentioned above,the author makes a model,using three-dimensional model software—Blender,and operations like cutting,rotating,and zooming to create two-dimension and three-dimensional three views,making it a power point slide show or flash so as to use it in class and get the relative feedback.Experimental test about the research will be includeed in chapter five.It can be concluded that this teaching method is feasible and effective.The key is to use professional software to find the effective and simple teaching method of threedimension geometry,assisting teachers to cultivate students' ability of spatial visualisation.
