High School Three-dimensional Geometry Learning Problems And Teaching Strategies Research

The college entrance examination has a very important effect on students' future as the way to select talents.As the important part of senior mathmatics,the Solid Geometry accounts for fifteen percent in the college entrance examination.Moreover,the study of Solid Geometry can improve the students' ability to visual perception,observation and discovery,induction and analogy,spatial imagination,abstract epitome,etc.In addition,these abilities will certainly promote the progress of other aspects.Thus,a positive cycle will get formed.In this paper,a depth research on the solid geometry in senior high school knowledge system has been carried out.And it tries to find out the students' obstacles in the learning process of Solid Geometry and the scientific and reasonable teaching countermeasures which will be beneficial to students.In this study,firstly,the factors that disturbed students in the learning process of Solid Geometry are found according to the research results of predecessors.Then,the preliminary theoretical teaching strategies based on the Humanistic Learning Theory,Constructive Learning Theory,Study Transfer Theory and Trial-and-Error Learning Theory are obtained.What's more,this study carried out a further interpretation to the problem solving methods from the following two aspects: the learning obstacles and teaching strategies.Finally,the unexpected obstacles that students showed in the teaching and learning activities are collected.Furthermore,the preliminary theoretical teaching strategies are sublimated in practice.As a result,the practical significance of these teaching strategies are endowed.
