Find Dyscalculia by Qualitative assessment, not by tests alone

Dyscalculia: News from the web:

Classifying students with mathematics learning disability (MLD, or dyscalculia) is typically based on composite scores from broad measures of math achievement, These scores may predict later math achievement levels but do not specify the nature of math difficulties likely to emerge among students at greatest risk for long-term failure in math.

Recent research from the University of Minneapolis suggests that specific qualitative assessments of symbolic number knowledge in early grades may reveal more about children’s thinking about numbers than does a typical “pass or fail” test. This in turn may reveal which students are most at risk for persistent poor math outcomes in future years,

Gender and Dyscalculia

Dyscalculia: News from the web:

In a recent UK study they looked at gender differences related to Developmental Dyscalculia. The outcomes show that when you look at absolute measures there is no differences in the prevalence of DD but when you apply a Math-Reading discrepancy measure there is a gender difference.

Defining and Diagnosing Developmental Dyscalculia

Dyscalculia: News from the web:

The studies into what defines Dyscalculia are not a numerous as the studies into Dyslexia. The definitions and diagnoses vary also from study to study. Still a huge percentage of the population is known for severe difficulties with Math. The writers suggest a developmental model of Dyscalculia to categorize the various causes of difficulty with math. Their main points:

• There is convincing evidence that basic numerical skills are impaired in Developmental Dyscalculia (DD). Therefore, purely educational (curricular) tests are not adequate to tap the characteristic numerical deficits associated with DD.
• DD is a heterogeneous disorder (like other neurodevelopmental disorders). Multi-dimensional assessments tracking different numerical representations and arithmetic processes should be used to evaluate response accuracy, speed,

Math anxiety in students

Posted on by

Dyscalculia: News from the web:

A study in Math anxiety among students across various majors is presented.

Math anxiety is a phenomenon that has increased over the 20th century, especially in the US.While emotional and disease models have been used to explain the experience, social learningtheories have increasingly been used to explain causality. The cost of math anxiety is high forsocieties because career choices, including those that rely on higher education, can be influencedby its presence.

Fractions and Dyscalculia

Posted on by

Dyscalculia: News from the web:

Researchers at the University of Minnesota have confirmed that there is a clear distinction between children with Low Achievement and Dyscalculia when evaluating fraction problems. Where children with Low Math Achievement typically get caught up by grade 8, the difficulties in solving Fraction problems continue through grade 8 for those with Dyscalculia. This and some more great findings in the report that you can find in the Journal of Experimental Child Psychology.
