Scientific practices increasingly incorporate sensors for data capture, information visualization for data analysis, and low-cost mobile devices for field-based inquiries incorporating open web standards. While a broad range of design approaches for developing technology-enhanced learning has been used by researchers and practitioners for the last 15 years,(More)
In this paper we explore a new direction for pedagogical computer characters, which we believe will maximize students' learning gains and enjoyment. To the traditional scenario where students interact primarily with a single coach or tutor character on-screen, we introduce the addition of both a social, animate colearner, and the student's own avatar(More)
Designers today use a variety of artifacts — both physical and digital — in the course of documenting their work. Physical and digital media have significantly different affordances and organizing metaphors: most notably, paper remains the preferable medium for sketching but lacks the sharing affor-dances of digital media. Augmented paper interactions(More)
I.-INTRODUCTION: Most of the research within the field of interactive characters has concentrated on generating guidelines, or models, for believable individual variability among characters, often based on psychological personality models (such as Nass, Isbister and Lee, 2000), or biological behaviors (for example, see Blumberg, 1994). In contrast, we(More)
Code It! fosters mathematics learning environments where pre-algebra students use handheld technologies to confidently and enjoyably explore and learn about functions. The resources we developed-server-based and handheld software and paper-based student and teacher texts-were packaged as a 20-session unit on code making and breaking and designed to boost(More)
Social responses to lifelike characters can significantly alter human evaluations of technology. This study tested the differences between a picture of an on-screen character interacting in three different contexts (retail purchase, health advice, reading survey) versus a three-dimensional robot conducting the same interactions off screen. A laboratory(More)
In a collaborative task, group dynamics have been shown to affect students' grades, motivation to pursue a topic or subject, documentation of the experience, learning, enjoyment of a project, and relationships with their classmates. The results presented in this paper illustrate the effect team dynamics also have upon technology appropriation, by combining(More)
As computer systems are evolving and coming to be regarded as social actors, the importance of social intelligence that enables natural and socially appropriate interactions is gaining a growing interest among the human-computer interaction researchers. This article discusses the definition, importance, and benefits of social intelligence as agent(More)
