学习作为一种活动 ,是学习者高层次的精神活动 ,是个体知识及其结构的相关变化 .为了探讨这种变化规律 ,我一直在寻找一种“金字塔”式编码系统 ,来优化这种结构 .说“金字塔” ,就是希望它能起到“一管窥全貌”、“会当凌绝顶 ,一览众山小”的效果 ;说“系统” ,就像计算机的 As an activity, learning is a high-level spiritual activity of learners. It is the change of individual knowledge and its structure. To explore this law of change, I have been looking for a “pyramid” coding system to optimize this structure. Say “Pyramid” is to hope that it can play the role of “a glimpse of the whole picture” and “will be extremely effective when you are on top of the hill”. The “system” is like a computer.
