The authors of this article discuss three pedagogical approaches, learning community, community of practice and community learning, and analyse their significance for knowledge acquisition and construction in higher education. The authors also explore the roles of technology in creating adequate environments for educators to implement teaching practices supported by these approaches and explain, through an illustrative course example, how technology and teaching methods can be used together to promote interaction among learners and help them achieve course goals.
Robotic Autonomy is a seven-week, hands-on introduction to robotics designed for high school students. The course presents a broad survey of robotics, beginning with mechanism and electronics and ending with robot behavior, navigation and remote teleoperation. During the summer of 2002, Robotic Autonomy was taught to twenty eight students at Carnegie Mellon West in cooperation with NASA/Ames (Moffett Field, CA). The educational robot and course curriculum were the result of a ground-up design effort chartered to develop an effective and low-cost robot for secondary level education and home use
Sage is a robot that has been installed at the Carnegie Museum of Natural History as a full-time autonomous member of the staff. Its goal is to provide educational content to museum visitors in order to augment their museum experience. This paper discusses all aspects of the related research and development. The functional obstacle avoidance system, which departs from the conventional occupancy grid-based approaches, is described. Sage's topological navigation system, using only color vision and odometric information, is also described. Long-term statistics provide a quantitative measure of

This study was designed to contribute to a small but growing body of knowledge on the influence of gender in technology-rich collaborative learning environments. The study examined middle school students’ attitudes towards using computers and working in groups during scientific inquiry. Students’ attitudes towards technology and group work were analyzed using questionnaires. To add depth to the findings from the survey research, the role of gender was also investigated through the analysis of student conversations in the context of two activities: exploring science information on a hypertext

Museums are excellent locations for testing ubiquitous systems; the Exploratorium in San Francisco offers a unique and challenging environment for just such a system. An important design consideration is how users switch between virtual and physical interactions.

In this study our goal is to conduct a "connective ethnography" that focuses on how gaming expertise spreads across a network of youth at an after-school club that simultaneously participates in a multi-player virtual environment (MUVE). We draw on multiple sources of information: observations, interviews, video recordings, online tracking and chat data, and hundreds of hours of play in the virtual environment of Whyville ourselves. By focusing on one particular type of insider knowledge, called teleporting, we traced youth learning in a variety of online and offlien social contexts, both from
Girls and women, especially if they are people of color, supposedly do not like computer technology or science. Myriad reports and studies document their limited interest and participation in these fields, both in school and at work. This article reports some preliminary results from an after-school intervention intended to increase urban, African-American middle school girls' interest and participation in computer technology and science. The intervention program was designed by university researchers, community developers, and local residents to correspond to state curriculum content
This article describes the software architecture of an autonomous, interactive tour-guide robot. It presents a modular and distributed software architecture, which integrates localization, mapping, collision avoidance, planning, and various modules concerned with user interaction and Web-based telepresence. At its heart, the software approach relies on probabilistic computation, on-line learning, and any-time algorithms. It enables robots to operate safely, reliably, and at high speeds in highly dynamic environments, and does not require any modifications of the environment to aid the robot's
The article reviews the strikingly divergent viewpoints of intellectuals—scientists and non-scientists—about “Science” and “Technology.” It shows that while scientists implicitly accept the difference between “Science” and “Technology,” to non-scientists that difference is irrelevant. The most important differences between “Science” and “Technology” that lie in their relative scales, outputs and accuracy of predictions are highlighted. The complexity of and difficulty in trying to quantify the contribution of science and technology to economic growth are discussed. Views of science and
The concern with a "digital divide" has been transformed from one defined by technological access to technological prowess--employing technologies for more empowered and generative uses such as learning and innovation. Participation in technological fluency-building activities among high school students in a community heavily involved in the technology industry was investigated in a study of 98 high school seniors enrolled in AP-level calculus. Findings indicated substantial variability in history of fluency-building experiences despite similar levels of access. More and less experienced
This article describes the Quest Atlantis (QA) project, a learning and teaching project that employs a multiuser, virtual environment to immerse children, ages 9–12, in educational tasks. QA combines strategies used in commercial gaming environments with lessons from educational research on learning and motivation. It allows users at participating elementary schools and after-school centers to travel through virtual spaces to perform educational activities, talk with other users and mentors, and build virtual personae. Our work has involved an agenda and process that may be called socially

The Situating Hybrid Assemblies in Public Environments (SHAPE) project within the European Disappearing Computer initiative has explored how emerging ubiquitous technologies can support museum visiting experiences. SHAPE has designed hybrid artifacts that support visitors manipulating phisical and digital material in a visible and interesting manner.
