本文关注的是如何以及有头指令有理数概念的基础上，连续的操作援助的儿童能够转移他们的知识，以完成任务的基础上，操作援助，可以解释为离散的。所使用的辅助工具是一个鸡蛋盒，如果受试者认为这些孔是突出的，那么它是离散的;另一方面，如果受试者关注每个孔的边缘所包围的总面积的比例，那么它被视为一个连续的实体。
This paper is concerned with how well children who have head instruction about rational number concepts based on a continuous manipulative aid are able to transfer their knowledge to accomplish tasks based on a manipulative aid which can be interpreted as discrete. The aid used was an egg carton which, if the subject views the holes as salient, is discrete; if, on the other hand, the subject focuses on the proportion of total area enclosed by the edges of each of the holes, then it is viewed as a continuous entity.
