Fostering collaboration with asymmetric roles in accessible programming environments for children with mixed-visual-abilities

Abstract

Introduction of computational thinking training in early childhood potentiates cognitive development and better prepares children to live and prosper in a future heavily computational society. Programming environments are now widely adopted in classrooms to teach programming concepts. However, these tools are often reliant on visual interaction, making them inaccessible to children with visual impairments. Also, programming environments in general are usually designed to promote individual experiences, wasting the potential benefits of group collaborative activities. We propose the design of a programming environment that leverages asymmetric roles to foster collaborative computational thinking activities for children with visual impairments, in particular mixed-visual-ability classes. The multimodal system comprises the use of tangible blocks and auditory feedback, while children have to collaborate to program a robot. We conducted a remote online study, collecting valuable feedback on the limitations and opportunities for future work, aiming to potentiate education and social inclusion.
