Inhibit The Ability To Solve Arithmetic Problems Of Redundant Information In Children

This paper studied the problem of redundant information arithmetic applications are simple mathematical problem, Only increase some irrelevant information that will not help solve the problem. An example of this type of problems is the following: "At the grocery there are 20 baskets of fruit, of which 12 of pears, and 9 baskets of vegetables. How many baskets are there in the shop?" In such problems, both contain useful information for problem-solving, but also contain useful information. In order to solve the problem correctly, the child has to pick out the data which is relevant for the solution ("20 baskets of fruit" and "9 baskets of vegetables") ignoring the rest ("12 of which are pears"). Hence, redundant data problems can be considered as a subtype of the classic class-inclusion problems first introduced by Piaget such as "In a bunch of flowers there are eight daisies and five tulips. Are there more daisies or flowers?" According to Piaget, only 8-year-old or older children succeed in this task when they achieve the logical competence of coordinating the relation between the two included subclasses A (daisies) and A' (tulips) and the superordinate general class B (flowers): A+A'=B, so that necessarily A
