摘　　要：作为辅助性教学手段,"几何画板"在数学命题变式教学中具有举足轻重的作用.其形象化、可视化、动态化的特征使它能够降低认知负荷、优化学生的认知结构.同时,实施各种变式,能够更好地促进高等数学教学过程中的命题教学.而基于"几何画板"的数学命题变式教学,体现在公式、定理和法则等方面.As a supplemental means of teaching,the Geometer＇s Sketchpad（GSP）has an important role in the mathematical teaching of propositional variant.Its visual and dynamic features enable it to reduce the cognitive load and optimizing the students cognitive structure.At the same time,the implementation of various variants can promote the teaching of the proposition during the teaching course of higher mathematics.And the mathematical teaching of propositional variant based on the Geometer＇s Sketchpad is related to the formula,theorems and laws and so on.
