Research on gesture development has mostly focused on home environments. Little is known about early communicative development in other relevant contexts, such as early-year-schools. These settings, rich in diverse educative situations, objects, and communicative partners, provide a contrast to parent-child interactions, complementing our…

A fundamental question in early childhood mathematics concerns the relationship between young children's own informal signs and the formal abstract symbolic language of mathematics. This study presents research investigating the genesis of mathematical semiosis from a Vygotskian cultural-historical (social-semiotic) perspective. In this study we…

This research explored the transformative potential of technology in special education, informed by the researcher's extensive experience in the Los Angeles Unified School District. Highlighting the case of a nonspeaking student with autism who made significant academic progress using an augmented alternate communication (AAC), device, the study…

Background: In the last decades, children's understanding of mathematical principles has become an important research topic. Different from the commutativity and inversion principles, only few studies have focused on children's understanding of the addition/subtraction complement principle (if a - b = c, then c + b = a), mainly relying on verbal…

This study focuses on the nature of children's participation in an Australian early childhood context in which their second language is used. The aim is to create knowledge of toddlers' modes and trajectories of participation. Empirical data documenting the participation of two toddlers were gathered through video observations of everyday…

It has been suggested that the differences observed for dyslexic readers compared to normal readers on tasks measuring visual sensitivity may simply be the result of differences between the two groups in general cognitive ability and/or attentional engagement. One common way to accommodate this proposal is to match normal and dyslexic readers on…
