In this article I bring artistic production into the learning sciences conversation by using the production of representations as a bridging concept between art making and the new literacies. Through case studies with 4 youth media arts... more
An exploratory study of77 high ability Grade 5 and 6 children investigated links between their understanding of the numeration system and their representations of the counting sequence 1–100. Analysis of children’s explanations, and... more
Learning science research has examined how external representations can be used to foster student reasoning and understanding. This paper describes additional roles that students' representations play in a reform mathematics... more
Many current neurophysiological, psychophysical, and psychological approaches to vision rest on the idea that when we see, the brain produces an internal representation of the world. The activation of this internal representation is... more
Living humans are unique among the animal kingdom with respect to their ability to externalize mental representations outside the brain through a variety of media and in a recursive or creative manner (i.e., generating a potentially... more
The nodes of a Blue Gene supercomputer are connected by five networks, four of unusual design. Only the I/O nodes have a conventional IP-based Ethernet. Plan 9�s internal and external representations of networks is simple and clean yet... more
Multimedia learning environments usually combine multiple forms of representations like texts, pictures, animations, tables or formulas. However, knowledge acquisition from multiple representations requires the integration of these... more
Computer-supported collaborative learning (CSCL) environments, particularly environments where students share external representations, are discussed as an interesting area for the application of cognitive load theory (CLT). CSCL... more
Computer Supported Collaborative Learning (CSCL) systems are assumed to have the potential to enhance the effectiveness of peer learning interactions (Andriessen et al., 1996; Dillenbourg, 1999). Groupware programmes are used for CSCL as... more
Sketching in a design context serves not only as a visual aid to store and retrieve conceptualizations but also as a medium to facilitate more ideas, and to revise and refine them. We examine whether designing is possible without... more
