分数知识是一种非常抽象的概念,而对于低年级学生而言,其处于儿童阶段,很难充分理解这种概念。所以通过实验可以得知在低年级学生形成分数概念时,能够运用认知负荷理念中交互性、通道效应以及反馈形式等因素,对分数概念的学习过程进行影响、改变。 Fractional knowledge is a very abstract concept, and for younger students it is in childhood and difficult to fully understand the concept. Therefore, it can be learned through experiments that in the formation of fractional concepts in lower grade students, we can use factors such as interactivity, channel effect and feedback form in cognitive load concept to influence and change the learning process of fractional concepts.
