LOPEZ-MOJICA, José Marcos. Understanding the probability at young with intellectual disability. Rev. Cient. [online]. 2018, n.33, pp.306-315. ISSN 0124-2253.  https://doi.org/10.14483/23448350.13326.

This report is part of a larger investigation that was interested in characterizing the probabilistic thinking of children with disabilities. In particular, the document shows the use of compensatory schemes related to the probabilistic thinking of children with intellectual disabilities. Three guiding axes govern the research, qualitative and ongoing: epistemological, cognitive and social. Here are presented the results of the third phase that concerned the understanding of the fundamental ideas of probability, after teaching, of three young people (15-17 years old) with intellectual disability of the third degree of special secondary, revealed in semi-structured individual interviews in the Gesell camera on the frequency approach of probability. The strategy was to give students the role of examiner to obtain data of their understanding of the mathematical concepts included in what they examine. The results concern the use of working memory, the visual perceptual scheme and the attention for the ideas of sample space, probability measure and random variable (qualitatively with absolute frequencies).

Keywords : probability; intellectual disability; special education; school mathematics.
