tandfonline.com – The neural basis of arithmetic and phonology in deaf signing individuals

tandfonline.com har udgivet en rapport under søgningen “Teacher Education Mathematics”: ABSTRACT ABSTRACT Deafness is generally associated with poor mental arithmetic, possibly due to neuronal differences in arithmetic processing across language modalities. Here, we investigated for the first time the neuronal networks supporting arithmetic processing in adult deaf signers. Deaf signing adults and hearing non-signing peers performed arithmetic and phonological tasks during fMRI scanning. At whole brain level, activation patterns were similar across groups. Region of interest analyses showed that although both groups activated phonological processing regions in the left inferior frontal gyrus to a similar extent during both phonological and multiplication tasks, deaf signers showed significantly more activation in the right horizontal portion of the inferior parietal sulcus. This region is associated with magnitude manipulation along the mental number line.… Continue Reading →

Eric.ed.gov – Teaching Mathematics Vocabulary with an Interactive Signing Math Dictionary

eric.ed.gov har udgivet: State frameworks and national standards are explicit about the mathematics content that students must master at each grade level. Although the Individuals with Disabilities Education Act and the No Child Left Behind Act mandate that students who are deaf or hard of hearing and communicate in sign language have access to this content, evidence suggests that it remains out of reach for many in this group. The purpose of the implementation research described in this article was to examine use of a Signing Math Dictionary (SMD) to help students who are members of this population access the vocabulary required to master the mathematics content that underlies the topics they are studying. The study included eight separate classes and a total of 39 participants–8 teachers and 31 students–representing… Continue Reading →
