Spatial ability used to detect Dyscalculia

Dyscalculia: News from the web:

A thesis from 1996 had as purpose:

The purpose of this study was to examine how spatial
abilities as measured on the Kaufman Assessment Battery for
Children (K-ABC) could be used to predict dyscalculia.

Spatial abilities were found to be most closely approximated on the
Spatial Memory subtest in the ability battery. This subtest
was examined in relationship to the Arithmetic subtest on the
achievement battery, and a high correlation was demonstrated.

This is interesting because there was critisism about the traditional way of assessing Dyscalculia by comparing ability (IQ) with achievement and this was a great measure to serve as an alternative.

How much do educators in the UK know about dyscalculia?

Dyscalculia: News from the web:

There is a PhD student from Loughborough University trying to find that out.

Their study has the following aims:

1. Educators’ awareness, knowledge and understanding of dyscalculia (a specific learning disorder in mathematics) and co-occurring developmental disorders.

2. Educators’ experiences of pre-qualifying and in-service training in dyscalculia and other developmental disorders.

3. Strategies and interventions that are currently working well to support children at risk of dyscalculia.

4. Educators’ perceptions about what might be beneficial in improving the outcomes of children at risk of dyscalculia.

dyscalculia research

Dyscalculia: News from the web:

We had to share this research paper about interventions in teaching math to students with learning disabilities. The short is that the interventions were successful, for a longer and more in-depth see below, for the whole paper, click the read all about it link

The purpose of this study was to examine the effects of utilizing explicit instruction, point-of-view video modeling, and augmented reality technology to teach mathematics to students with disabilities. A multiple probe single-case research design was used. Three students with learning disabilities who were receiving special education services in mathematics participated in the study. The results were analyzed using visual analysis of trend, level, and variability. Tau-U was calculated to be 0.98 on the participants’ overall results from baseline to intervention. The results demonstrated a functional relation between the intervention and the students’ performance on three rational number mathematics skills. Participants’ maintenance and generalization of the rational number skills were measured with variable findings. The intervention was determined to be socially valid by the participants and teachers.

Here is where we find dyscalculia

Dyscalculia: News from the web:

Wonderful study that shows real differences between the brains of typical developing children and those with developmental dyscalculia.

we did find significant differences in regions-of-interest tracts which had previously been related to math ability in children. The major findings of our study were reduced white matter coherence and shorter tract lengths of the left superior longitudinal/arcuate fasciculus and left anterior thalamic radiation in the DD group. Furthermore, lower white matter coherence and shorter pathways corresponded with the lower math performance as a result of the correlation analyses. These results from regional analyses indicate that learning, memory and language-related pathways in the left hemisphere might underlie DD.

Telling time and dyscalculia

Dyscalculia: News from the web:

Considering that difficulties in reading clocks in early classes can be an early indicator of
dyscalculia, classroom teachers may need to pay close attention to the difficulties experienced by six and seven-year-old children (Burny et al., 2012). In addition, considering the procedural, semantic,
and spatial difficulties experienced by dyscalculic children, certain adaptations can be made to make it
easier for them to learn to read clocks.
