MAGINA, Sandra; BEZERRA, Francisco Brabo  e  SPINILLO, Alina. Como desenvolver a compreensão da criança sobre fração? Uma experiência de ensino. R. Bras. Est. Pedag. [online]. 2009, vol.90, n.225, pp.411-432. ISSN 2176-6681.

This study involves a teaching experiment aimed to improve children’s understanding of fractions. 57 children (8-10 years old) were divided into 3 groups: Experimental and Control Groups: 3rd graders with no previous instruction in fractions; and Reference Group: 4th graders who were taught in a traditional way based on a mechanistic approach to fractions and focused on application of rules. The children who participated in the Experimental Group were offered a teaching experience based on the resolution of problem-situations involving fractions as quotient and as part-whole relationship. Those situations were presented through combinations and comparisons among different representation supports, in a discussion context in which the children reflected on the solution processes adopted. All participants were given a pre and a post-test. The Experimental Group showed a more expressive improvement than the other groups.
