Dyscalculia: News from the web:

We know that people who can easily work with both actual quantities like objects or dots and with written arabic numerals and can also easily translate between them so between the non symbolic and symbolic information, have good math skills. Reason to look into the question how the brain codes numbers like 2, 4, 6, 8 if brain sources are used for both symbolic and nonsymbolic information or that they is located in separate spots. Researchers from Western University in Canada and VanderBilt, Nashville did an fMRI study with 139 healthy adults. They used a 7 Tesla machine, which is very powerful so a great signal noise quality. They found that for specific numbers, like 4 and 6, the same neural resource was used to code for quantities of dots and written arabic numerals and also that both the left and right parietal lobes were active, also the dorsolateral prefrontal cortex and that the process is specific to individual numbers in multiple formats. Not everything can be unraveled yet and how this relates to math performance and that there are individual differences in working with symbolic and non-symbolic numbers depending on their math skills

MathFun is a mobile app created by the mobile app developer while following the Calculic Model approach for Malaysia Dyscalculia children. The outcomes of this paper view on the effectiveness of the model towards building a mobile application for these children. Usability was performed in order to assess the usability and verifying the effectiveness of MathFun. This study involved 3 teachers and three children. Descriptive analysis was performed from the collected data. Based on the outcome, it’s shows that by using the suggested model there is an increased in the acceptance and usability of the application by the children.

Dyscalculia: News from the web:

Dyscalculia is one of the less well-known learning problems in mathematics due to lack of exposure and study. Children with dyscalculia usually face arithmetic and symbolic number comparison issues, with about 3-6 percent of individuals affected. The lack of wide-ranging study and inconsistency in the condition’s characterizations through studies have impeded progress in identifying the root causes of dyscalculia and how best to handle it. This problem can be more serious because it can prolong up to adulthood. Therefore, this paper will discuss the general aspects related to dyscalculia problems and their effects on children in their lives. This paper also explains the signs and symptoms that are needed to understand children who may have dyscalculia. Finally, this paper discusses what treatments or methods can be used significantly to help children improve their mastery and mathematical skills,

The results of this large study show no significant impact of the home math environment on the children’s numerical and patterning skills. However the authors remark the following:

One explanation for these findings might relate to the characteristics of the general preschool system in the country of the present study (Belgium). Future studies should consider the effect of the preschool learning environment because it might explain differences between studies and countries with regard to the home math environment and its association with mathematical skills.
