Open collaborative authoring systems such as Wikipedia are growing in use and impact. How well does this model work for the development of educational resources? In particular, can volunteers contribute materials of sufficient quality? Could they create resources that meet students’ specific learning needs and engage their personal characteristics? Our experiment explored these questions using a novel web-based tool for authoring worked examples. Participants were professional teachers (math and non-math) and amateurs. Participants were randomly assigned to the basic tool, or to an enhanced

Community technology centers (CTCs) help bridge the digital divide for immigrant youth in disadvantaged neighborhoods. A study of six CTCs in California shows that these centers also promote positive youth development for young people who are challenged to straddle two cultures.

This paper suggests new strategies for introducing students to robotics technologies and concepts, and argues for the importance of providing multiple entry points into robotics. In particular, the paper describes four strategies that have been successful in engaging a broad range of learners: (1) focusing on themes, not just challenges; (2) combining art and engineering; (3) encouraging storytelling; (4) organizing exhibitions, rather than competitions. The paper describes a new technology, called the PicoCricket, that supports these strategies by enabling young people to design and program

Multimodal technologies are creating new experiential opportunities for exploring, tinkering, learning and interacting in the virtual world. Once combined with sensorial objects and open-ended activities in the physical world, they introduce a new genre of interactive environments called ThinkeringSpace. ThinkeringSpace is a hybrid system - made of networked and remotely accessible physical environments - that seeks to bring school-age children together to collaborate face-to-face and tinker with things, both physical and virtual, reflect upon what they do and discover, and elaborate their

Creating multiple prototypes facilitates comparative reasoning, grounds team discussion, and enables situated exploration. However, current interface design tools focus on creating single artifacts. This paper introduces the Juxtapose code editor and runtime environment for designing multiple alternatives of both application logic and interface parameters. For rapidly comparing code alternatives, Juxtapose>introduces selectively parallel source editing and execution.

We are in the midst of an explosion of emerging humancomputer interaction techniques that redefine our understanding of both computers and interaction. We propose the notion of Reality-Based Interaction (RBI) as a unifying concept that ties together a large subset of these emerging interaction styles. Based on this concept of RBI, we provide a framework that can be used to understand, compare, and relate current paths of recent HCI research as well as to analyze specific interaction designs. We believe that viewing interaction through the lens of RBI provides insights for design and uncovers

This paper demonstrates a pressure-sensitive depth sorting technique that extends standard two-dimensional (2D) manipulation techniques, particularly those used with multitouch or multi-point controls. Then analyzes the combination of this layering operation with a page-folding metaphor for more fluid interaction in applications requiring 2D sorting and layout.
