Dyscalculia caused by bad teaching?

Dyscalculia: News from the web:

Well one Dutch professor thinks so and points at a study where pupils got 6 weeks of arithmetic drilling and that put them 18 months ahead. The question is for how long that advantage stayed and if those pupils had been rightfully diagnosed with dyscalculia

The role of language in Mathematics

Dyscalculia: News from the web:

Martin Saunders writes a good story about the role of language in children’s learning of Mathematics. His conclusion (but you really need to read the whole piece in our link for today):

In summary, it is clear that language is a requirement for mathematical cognition, if not higher cognition in general. Where language is a component of understanding it must also be a requirement for the learning process. A symbiotic relationship exists where dialogue, and in particular creating explanations, aids to build understanding but also to apply this understanding in ever more complex ways. As the ability to consider multiple conceptual areas collectively grows and with number facts readily available a proficient mathematician develops who is able to reason and problem solve with fluency.

Primary and Secondary Developmental Dyscalculia

Dyscalculia: News from the web:

Great article with indepth information about dyscalculia

Do read the whole article but here is the punch line:

Mathematical performance deficits, Developmental Dyscalculia, may arise because of a wide range of factors, from poor teaching, to low socio-economic status, to behavioral attention problems. However, a subset of children with math difficulties, possibly with the most-severe impairments, appears to suffer from a developmental learning disorder that undermines the ability to process basic numerical magnitude information, and that impairment in turn undermines the acquisition of school-level arithmetic skills. This disorder, “primary developmental dyscalculia,” should not be confused with “secondary developmental dyscalculia,” which refers to mathematical deficits stemming from external factors such as those described above. Instead, primary DD is associated with impaired development of brain mechanisms for processing numerical magnitude information and is thus driven by endogenous neurodevelopmental factors.
