Instruction Design Of "Spherical Geometry" And Experimental Study

Mathematic curriculum standard (laboratorial version) of senior high schools was issued in April, 2003. A lot of selected topic was fixed in this curriculum standard for the first time. These content of selected topic are new and frontier, it is a severe challenge to the senior high school teachers."Spherical Geometry"is the one of selected topic, many teachers feel more strange and difficult to teach. Therefore, it is necessary for the normal university students to learn about selected topic of senior high schools before they graduate. So it is meaningful to study"Spherical Geometry"instruction design to the normal university students.Firstly, this study investigated by questionnaire to senior high school teachers and the normal university students of Guizhou province about"Spherical Geometry",It sures the necessity of instructional design of Spherical Geometry. A systematic instructional design about Spherical Geometry based on their logical system. including the learning analysis, contents analysis, strategies making, fixing of teaching process, exploitation of instructional resource, implement, and evaluation were made.Secondly, the experimental work about"Spherical Geometry"has been carried out so that above-mentioned instruction design can be tested. The results show that setting instruction design program about Spherical Geometry is feasible. At the same time, analogy is used most frequently at learn Spherical Geometry; student's school work evaluation should adopt diverse evaluate methods; the writing of the teaching material should perfect step by step in practice.Finally, Summarize this study'lacking and prospect.
