          Abstract

          Pesquisas têm demonstrado que as crianças que se desenvolvem tipicamente constroem conceitos matemáticos desde muito cedo. Esse processo de desenvolvimento cognitivo parece estar intimamente conectado com o desenvolvimento da linguagem verbal. O que acontece com o desenvolvimento matemático de crianças que possuem uma forma diferente de linguagem, como a língua de sinais utilizada pelos surdos? Essa pergunta, além de demais indagações sobre o baixo desempenho em matemática de alunos surdos documentado por outros estudos, orientou o desenvolvimento da pesquisa aqui apresentada. Para responder a tais questionamentos, foram realizados testes experimentais com crianças surdas (grupo 1), crianças ouvintes mais jovens da escola pública (grupo 2), crianças ouvintes mais velhas da escola pública (grupo 3) e crianças da escola privada (grupo 4). Os resultados evidenciaram uma clara distinção entre habilidades cognitivas matemáticas mais dependentes e menos dependentes do estímulo linguístico, notificando que crianças surdas têm o mesmo desempenho ou, em alguns casos, até mesmo um desempenho superior do que crianças ouvintes em habilidades menos dependentes do estímulo linguístico. Contudo, tanto as crianças surdas quando as crianças ouvintes mais jovens da escola pública demonstraram um desempenho significativamente baixo em relação às crianças ouvintes mais velhas da escola pública e às crianças da escola privada. Tal resultado indica que a surdez não é causa de baixo rendimento escolar na área da matemática. Assim, parece ser necessário pensar em formas de intervenção pedagógica que possam garantir uma aprendizagem de sucesso em matemática tanto para as crianças surdas, quanto para as crianças ouvintes que frequentam as escolas públicas brasileiras.

          Translated abstract

          Research has shown that children who develop typically build mathematical concepts very early. This process of cognitive development seems to be closely connected with the development of verbal language. What happens to the mathematical development of children who have a different form of language such as the sign language used by deaf people? This question, and other questions about deaf students' low performance in mathematics documented by other studies guided the development of the study presented here. To answer these questions, experimental tests were carried out with deaf children (group 1), younger hearing children from public schools (group 2), older hearing children from public schools (group 3) and children from private schools (group 4). The results evidenced a clear distinction between mathematical cognitive skills more dependent and less dependent on linguistic stimuli, notifying that deaf children have the same performance, or in some cases even higher performance than hearing children in skills less dependent on linguistic stimuli. However, both deaf children and younger hearing children from public schools had a significantly lower performance in comparison to older hearing children from public schools and children from private schools. This result indicates that deafness is not a cause of poor academic performance in mathematics. Thus, it seems necessary to think of forms of pedagogical intervention which can ensure the successful learning of mathematics for both deaf children and hearing children who attend public schools in Brazil.

            The Stanford Achievement Test, 9th Edition: National Norming and Performance Standards for Deaf and Hard-of-Hearing Students.

            C Traxler (1999)
            This article presents a rich context of information for interpreting Stanford Achievement Test scores and for describing the achievement of deaf and hard-of-hearing students. The publisher's national norming of the Stanford Achievement Test provides a context of actual performance of hearing students. The publisher's Performance Standards provide a context of expectations for hearing students as determined by a panel of experts. The Gallaudet Research Institute's norming of the test on a national sample of deaf and hard-of-hearing students provides a context of test performance by this special population. A smaller subsample of the deaf and hard-of-hearing students who take the same test levels as hearing students provides an additional reference group with respect to the Performance Standards. Information from these sources is brought together into two graphical contexts to address these questions: Can the normative data from the publisher's national standardization of the test with hearing students, and the normative data from the GRI's national norming of the test with deaf and hard-of-hearing students provide a useful context for the interpretation of individual test scores? Can they provide a useful way to examine achievement of groups of students? Can the new Performance Standards defined by the test publisher offer a useful context for test score interpretation for high-achieving deaf and hard-of-hearing students?
