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

Many biomedical research universities have established outreach programs for precollege students and teachers and partnerships with local school districts to help meet the challenges of science education reform. Science outreach programs held in university research facilities can make science more exciting and innovative for high school students and can offer them much more insight into the nature of science and laboratory research than is available in most high school science courses. This paper describes a long-term follow-up study of high school students enrolled in the Summer Science
The 4-H Study of Positive Youth Development (PYD), a longitudinal investigation of a diverse sample of 1,700 fifth graders and 1,117 of their parents, tests developmental contextual ideas linking PYD, youth contributions, and participation in community youth development (YD) programs, representing a key ecological asset. Using data from Wave 1 of the study, structural equation modeling procedures provided evidence for five firstorder latent factors representing the “Five Cs” of PYD (competence, confidence, connection, character, and caring) and for their convergence on a second-order PYD
Summer science programs held in university research facilities provide ideal opportunities for pre-college students to master new skills and renew, refresh, and enrich their interest in science. These types of programs have a positive impact on a student's understanding of the nature of science and scientific inquiry and can open a youngster's eyes to the many possible career opportunities in science. This paper describes a study of high school students enrolled in the Summer Science Academy program at the University of Rochester that investigates the program's impact on students' knowledge of

Two important content areas associated with informal environmental science programs are ecology/natural science topics and awareness of environmental problems/issues. This study attempted to evaluate which of these content areas may provide a more optimum learning experience. A quantitative analysis was conducted on two field trips to a science center that represented an ecological oriented program and an environmental issue presentation. Two variables that were chosen as indicators of program success—knowledge retention and attitude change—are outcomes that have been found prevalent in
This article explores the ways that mothers and children from primarily middle-income European American backgrounds reason about events in which biological and nonbiological objects change in size. In Study 1, mother–child conversations were examined to investigate the events mothers described as growth, as well as the ways mothers explained events occurring in different domains. Findings indicate that although mothers primarily discussed events in domain-specific ways, they exhibited some domain blurring in their talk to children. In Study 2, 3-year-old children (M=3 years, 2 months) and 5
The Jackprot is a didactic slot machine simulation that illustrates how mutation rate coupled with natural selection can interact to generate highly specialized proteins. Conceptualized by Guillermo Paz-y-Miño C., Avelina Espinosa, and Chunyan Y. Bai (New England Center for the Public Understanding of Science, Roger Williams University and the University of Massachusetts, Dartmouth), the Jackprot uses simplified slot-machine probability principles to demonstrate how mutation rate coupled with natural selection suffice to explain the origin and evolution of highly specialized proteins. The
The purpose of this article is to describe a community-based science project that was coproduced with urban teenagers and to elaborate on my understanding of what it means to create a practicing culture of science learning. This understanding will be positioned in relation to various educationally relevant discourses and research on urban science education, concluding with an exploration of these questions: In what ways did an urban planning and community gardening project help to create a learning environment in which science was relevant? To whom was science relevant and toward what ends? It
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
In this paper I focus on the transition from everyday to scientific ways of reasoning, and on the intertwined roles of meaning-making dialogue and science content as they contribute to scientific literacy. I refer to views of science, and how scientific understanding is advanced dialogically, by Hurd (Science Education, 1998, 82, 402-416), Brown (The Journal of Learning Sciences, 1992, 2(2), 141-178), Bruner (Acts of Meaning, Cambridge, MA: Harvard University Press, 1990), Roth (In J.

Free-choice learning and, derivatively, free-choice environmental learning emerges as a powerful vehicle for supporting diversity in learning styles (Falk & Dierking, 2002). In this article, I argue that free-choice environmental learning holds great potential for enabling us to understand what is at stake in environmental learning and thus help us build a sustainable future. I examine the different informal learning contexts for children, home (family and play), museums, zoos, nature parks and wilderness, among many others, and offer an explanation for how learning occurs in these settings
In this article we describe an instance of free-choice learning in the context of an eelgrass mapping and stewardship project (the Project) that covers over 500 kilometers of coastline in British Columbia, Canada, and involves 20 volunteer groups. In this ethnographic case study we sought to (a) explicate the relationship between individual and collective learning in this free-choice setting and (b) understand how a network of Project participants could both constitute a free-choice learning setting and support such a setting. We articulate a dialectic relationship between individual and
