策略是一种法则,是发现问题、解决问题的一种方法和规则.我们认为立体几何学习策略有二.其一是数学语言(文字语言、符号语言和图形语言)相互转化的学习策略;其二是寻找母体(大家都熟悉的几何体,如正方体、长方体等)的学习策略.因为几何学是研究现实世界中物体的形状、大小与位置关系的数学学科,所以在立体几何学习策略的应用过程中,我们通常采用直观感知、操作确认、思辨论证、度量计算等方法认识和探索几何图形及其性质.1.数学语言相互转化的学习策略.数学学习,事实上就是数学语言的学习,就是(按
Strategy is a kind of rule, a method and rule of discovering and solving problems, and we think that there are two strategies of learning solid geometry: one is the learning strategy of mutual conversion between mathematical languages (text, symbolic and graphic language); The second is to find the mother (familiar geometry, such as cuboids, cuboids, etc.) learning strategy.As the study of geometry in the real world object shape, size and location of the mathematical discipline, so in the application of three-dimensional geometric learning strategy , We usually recognize and explore the geometry and its properties by the methods of intuitionistic perception, operation confirmation, speculative argumentation, metric calculation, etc. 1. Learning strategies of mutual transformation of mathematical languages.Mathematical learning is in fact the study of mathematical language, that is, ( press
