Usar descaradamente los dedos para resolver una operación - TopicsExpress

Usar descaradamente los dedos para resolver una operación sencilla es un acto que se repite en todas las escuelas del mundo. Y es que, para miles de alumnos, una resta puede ser una operación extremadamente difícil; y para las sumas más complicadas, nunca hay suficientes manos... La cuestión es que muchos niños consideran que las matemáticas resultan complejas o aburridas. No obstante, tras su apreciación puede encontrarse un trastorno conocido como discalculia, que afecta a entre el 3% y el 7% de la población. Este fenómeno no solo preocupa a pedagogos y psicólogos, sino que también ha captado la atención de los neurocientíficos, interesados en comprender cómo nuestro cerebro procesa la información numérica y las operaciones matemáticas. Cuando observamos dígitos, se activan unos circuitos neuronales de un área del cerebro llamada giro temporal inferior. Las neuronas de los lóbulos frontal y parietal también se ponen en marcha cuando resolvemos problemas. Al determinar las zonas de la masa gris especializadas en el cálculo numérico, los investigadores han podido estudiar mejor las alteraciones específicas del cerebro discalcúlico. Use fingers to solve blatantly simple operation is an act that is repeated in all schools in the world. And, for thousands of students, a subtraction operation can be extremely difficult, and for more complicated sums, there are never enough hands ... The issue is that many children believe that mathematics are complex or tedious. However, after assessment may be a disorder called dyscalculia, which affects between 3% and 7% of the population. This phenomenon concerns not only educators and psychologists, but has also attracted the attention of neuroscientists are interested in understanding how our brain processes numerical and mathematical operations. When looking digits, neural circuits are activated an area of the brain called the inferior temporal gyrus. Neurons in the frontal and parietal lobes also are launched when solving problems. In determining the gray areas specialized in numerical calculation, researchers have been able to study better discalcúlico specific brain disorders.
