本研究探索概率概念开始萌芽、发展的年龄及感知动作、表象、概念三种认知成分在认知结构中的作用。结果表明:掌握概率概念经历:1.估计事件可能性,2.分析可能性随机分布的情况,3.估计随机分布事件的机遇大小,4.用具体数量表示机遇,5.概括机遇的比率等步骤。其认知结构中有分别以动作感知、表象、概念等中一种成分为主的动力变化,在5—11岁阶段,表象起极重要作用。对最简单概率的概念9岁才开始萌芽,10.11岁可算基本掌握,稍复杂的11岁才开始萌芽。
This study explores the role of probabilistic concepts in the initiation and development of age and the cognitive structures of cognitive actions, appearances and concepts. The results show that: mastering the concept of probabilistic experience: 1. Estimating the probability of an incident; 2. Analyzing the probability of random distribution; 3. Estimating the size of the chance of a randomly distributed incident; 4. Explicating the opportunity with a specific quantity; step. In the cognitive structure, there are dynamic changes in one of the components of action perception, appearance and concept, respectively. During the period of 5-11 years old, appearance plays an extremely important role. The concept of the simplest probability began to sprout at the age of 9, 10.11 can be considered a basic grasp of a bit complicated before the age of 11 began to sprout.
