This article reports on an investigation of African American families' perceptions and experiences in an after-school family-school involvement program at two inner-city schools. Centered in the sphere of sociocultural theory and situated cognition, this study focuses on family-child relationships to improve children's literacy using oral histories and technology. It also explores a model for preparing preservice teachers to work with families. Families indicated that prior to program implementation, they had received bureaucratic invitations of school involvement and empathized with other
Current empirical research in science and technology studies provides new and different views of science and scientists that contrast markedly with the mythical views that underlie many curricular efforts geared toward increasing scientific literacy. If descriptions of science and scientists that emerge from science and technology studies are legitimate, considerable implications arise for educational aims guiding science instruction, learning experiences directed toward those educational aims, and resources that support those learning experiences and educational aims. In this paper, we (a)
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 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
