          Abstract

          Abstract The aim is to assess contribution provided by soroban – or Japanese abacus – not only for the students’ learning of number and operations content, but also in the development of their higher psychological functions. As an applied nature, it was developed under a pedagogical intervention for data collection and analysis. The eight participants were adult students, aged 19 to 47 years old, who attended a special education school in a city in the countryside of the state of Paraná - Brazil. The data was analyzed through assessment of the conversation. The students with intellectual disabilities participating in the study had limited knowledge regarding the use of numbers and operations in school situations and in different contexts of everyday life, so these concepts were taught to them. After the pedagogical intervention, they showed advances in this knowledge, appropriating both the concept of numbers and the use of soroban as a tool for performing mathematical calculations. As it is a human right to appropriate the knowledge produced historically and culturally by mankind, which in turn leads to development, teaching the use of soroban to students with intellectual disabilities promoted the learning of mathematical concepts, developing superior skills such as thought, defending the thesis proposed by this study that cognitive limitations of the intellectually disabled are not barriers to learning of an array of educational concepts.

          Resumen El presente artículo es producto de una investigación que tuvo como objetivo comprobar las contribuciones del soroban, también llamado de ábaco japonés, para el aprendizaje del contenido de Educación Matemática “números y operaciones”, bien como para el desarrollo de las funciones psicológicas superiores en estudiantes con deficiencia intelectual. Los sujetos de estudio fueron ocho estudiantes adultos, de entre 19 y 47 años, que frecuentan una escuela de educación especial en un municipio del Estado del Paraná, Brasil. Se utilizó la observación participante e intervención pedagógica como herramientas para la colecta de datos, los que fueron registrados a partir de medios audio-visuales y diarios de campo. El análisis de datos reveló que los estudiantes con deficiencia intelectual presentaban conocimientos limitados en lo que se refiere al uso de números y operaciones, y no solo en situaciones escolares, sino también en distintos contextos cotidianos. Debido a ello, estos conceptos fueron enseñados teniendo como herramienta pedagógica el soroban. Después de esta intervención, los y las estudiantes presentaron avances, puesto que se apropiaron del concepto “número” y aprendieron a utilizar el soroban para la realización de operaciones matemáticas. Se considera como un derecho de todas las personas el apropiarse del conocimiento histórico-cultural producido por la humanidad; uno de estos es la utilización de números para realizar cálculos matemáticos. Nuestra investigación demuestra que la enseñanza del uso de soroban en estudiantes con deficiencia intelectual favorece el aprendizaje de los conceptos trabajados, desarrollando capacidades superiores como el pensamiento. Esto permite defender la tesis propuesta en el estudio: que las limitaciones cognitivas de personas con deficiencia intelectual no deben entenderse como barreras para el aprendizaje de “números y operaciones”.

            Abacus in the Brain: A Longitudinal Functional MRI Study of a Skilled Abacus User with a Right Hemispheric Lesion

            The abacus, a traditional physical calculation device, is still widely used in Asian countries. Previous behavioral work has shown that skilled abacus users perform rapid and precise mental arithmetic by manipulating a mental representation of an abacus, which is based on visual imagery. However, its neurophysiological basis remains unclear. Here, we report the case of a patient who was a good abacus user, but transiently lost her “mental abacus” and superior arithmetic performance after a stroke owing to a right hemispheric lesion including the dorsal premotor cortex (PMd) and inferior parietal lobule (IPL). Functional magnetic resonance imaging experiments were conducted 6 and 13 months after her stroke. In the mental calculation task, her brain activity was shifted from the language-related areas, including Broca’s area and the left dorsolateral prefrontal and IPLs, to the visuospatial-related brain areas including the left superior parietal lobule (SPL), according to the recovery of her arithmetic abilities. In the digit memory task, activities in the bilateral SPL, and right visual association cortex were also observed after recovery. The shift of brain activities was consistent with her subjective report that she was able to shift the calculation strategy from linguistic to visuospatial as her mental abacus became stable again. In a behavioral experiment using an interference paradigm, a visual presentation of an abacus picture, but not a human face picture, interfered with the performance of her digit memory, confirming her use of the mental abacus after recovery. This is the first case report on the impairment of the mental abacus by a brain lesion and on recovery-related brain activity. We named this rare case “abacus-based acalculia.” Together with previous neuroimaging studies, the present result suggests an important role for the PMd and parietal cortex in the superior arithmetic ability of abacus users.
