Mathematical competencies in children with different types of learning difficulties.

Abstract: The mathematical performance of 182 third and fourth graders in 8 different areas of mathematics was examined. The children belonged to 4 achievement groups: children with mathematic difficulties (MD only), children with both mathematic and reading difficulties (MD-RD), children with reading difficulties (RD only), and normally achieving children (control group). Both MD groups performed worse than the normally achieving children in all but 1 area, place value knowledge. The MD-only and the MD-RD children perf… Show more

“…Although, in general, verbal working memory was found to be as important as visual working memory in fourth graders, the difference between MLD and TD children is especially visible in visual working memory, which is in accordance with former literature (Ashkenazi et al, 2013;Szucs et al, 2013). This finding may be explained by the same mechanism that explains why visual working memory is more important in elementary math, while verbal working memory is more involved in later math (Van der Ven et al, 2013; Van de WeijerBergsma, : Children with MLD have difficulties with automatizing facts and procedures (e.g., Andersson, 2008;Geary et al, 2012), which leads to math problems being relatively 'new' for them, because they can't rely on memorized facts and procedures. Visual spatial working memory seems to be more involved in new problems, and thus in the problem solving of children with MLD.…”

“…Tal variação é condizente com os valores utilizados em outras pesquisas (por exemplo, Bull & Johnson, 1997;Geary et al, 2004;Geary et al, 1999;Orrantia, Martínez, Morán, & Fernán-dez, 2002 New Zealand, 2007). Na ausência de uma normatização para esse material foi realizada uma tradução e adaptação pela primeira autora do presente artigo, a qual constou de sua tese de doutorado (Costa, 2009 A resposta era considerada como utilizando um processo apoiado na memória, quando a criança respondia imediatamente, após a apresentação do cálculo, considerando 3 segundos, o tempo máximo de resposta apontado na literatura (Andersson, 2008;Russell & Ginsburg, 1984).…”

“…Ou seja, há evidências de que o armazenamento e/ou o acesso automático e preciso dos fatos aritméticos básicos da memória de longo prazo, são habilidades prejudicadas em estudantes com TDAH (Miranda-Casas et al, 2009), principalmente as do subtipo desatento (TDAH-D) e combinado (TDAH-C; Marshall, Hynd, Handwerk, & Hall, 1997). Tal recuperação, ou domínio de um fato básico (conforme Van de Walle, 2009), refere-se à habilidade de alcançar a resposta correta de forma rápida (geralmente de 2 a 3 segundos, segundo Andersson, 2008) e precisa, sem a necessidade de recorrer a expedientes auxiliares, como a contagem. Entende-se como fatos básicos aritméticos as combinações, de adição, subtração, multiplicação e divisão, entre dois fatores menores que dez (Van de Walle, 2009).…”

“…This information would presumably guide testers to help children through the solving process and to provide rich information about children's need for instruction. In particular, because children with arithmetic difficulties may, besides having difficulties with math skills, also have deficits related to specific multi-step problem-solving processes such as establishing a problem representation and developing a solution plan (Andersson, 2008;Bryant, Bryant & Hamill, 2000;Mädamürk, Kikas & Palu, 2016). We therefore developed six scenario-protocols for each step in the problem solving process of the complex version of the Seria-Think Instrument (Tzuriel, 1998;.…”
