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
Several instruments have been developed to assess student images of scientists, but most require children to respond in writing. Since not all children can respond appropriately to written instruments. Chambers (1983) developed the Draw-A-Scientist Test (DAST) in which children's drawings are rated according to particular characteristics present or absent in the drawings, allowing researchers to determine the images of scientists children hold. In order to improve the objectivity and interrater reliability of this means of assessment, the authors built upon Chambers' study to develop a

The purpose of this longitudinal case study is to describe the educational trajectories of a sample of 152 young women from urban, low-income, single-parent families who participated in the Women in Natural Sciences (WINS) program during high school. Utilizing data drawn from program records, surveys, and interviews, this study also attempts to determine how the program affected the participants' educational and career choices to provide insight into the role informal science education programs play in increasing the participation of women and minorities in science, math, engineering, and
Thomas Kuhn's notion of a disciplinary matrix provides a useful framework for investigating the growth of research on family learning in and from museums over the last decade. To track the emergence of this disciplinary matrix we consider three issues. First are shifting theoretical perspectives that result in new shared language, beliefs, values, understandings, and assumptions about what counts as family learning. Second are realigning methodologies, driven by underlying disciplinary assumptions about how research in this arena is best conducted, what questions should be addressed, and
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
We used meta-analysis to review 55 evaluations of the effects of mentoring programs on youth. Overall, findings provide evidence of only a modest or small benefit of program participation for the average youth. Program effects are enhanced significantly, however, when greater numbers of both theory-based and empirically based "best practices" are utilized and when strong relationships are formed between mentors and youth. Youth from backgrounds of environmental risk and disadvantage appear most likely to benefit from participation in mentoring programs. Outcomes for youth at-risk due to

In this study, detailed observations and interviews from a high school student's semester-long cooperative (co-op) placement in a dental practice are used to exemplify Hung's theoretical approach to understanding situated learning. Using Hung's theory of epistemological appropriation in an analysis of the co-op supervisor's regulatory behaviors (scaffolding, modeling, and coaching) and of the novice's corresponding regulatory behaviors (submitting, mirroring, and constructing) helped to explain the developments in this student's learning, actions, and beliefs. In contrast to the progression

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
