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
Women in the United States are underrepresented in science, mathematics, and engineering (SME) educational programs and careers. One cause is the dramatic and disproportionate loss of women who intended in high school to pursue science-related careers. This article uses the longitudinal survey responses of 320 male and female SME summer program students to assess the ways in which their social relationships and experiences affect their involvement in science and technology. The issues are framed in terms of identity theory. Structural equation models support the identity framework; emotionally
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
Research indicates that young children, unlike adults, have a generalized tendency to view not only artifacts but also living and nonliving natural phenomena as existing for a purpose. To further understand this tendency's origin, the authors explored parents' propensity to invoke teleological explanation during explanatory conversations with their children. Over 2 weeks, Mexican-descent mothers were interviewed about question-answer exchanges with their preschool children. Analyses revealed that children asked more about biological and social phenomena than about artifacts or nonliving

Despite the many hours students spend studying science, only a few relate to these subjects in such a manner that it becomes a part of their essential worldview and advances their education in a larger sense - one in which they make a connection to the subject matter so that it becomes a source of inspiration and occupies a formative position in their life. Using the hermeneutic/phenomenological sense of lifeworld as our being in the world, we explore questions of identity in the teaching and learning of science. We suggest that by taking the notion of identity in science to include students'
This paper explores the importance of iterative design and evaluation in developing playful learning experiences in museums. According to research, play has five defining aspects: it is structured by constraints, active without being stressful, focused on process not outcome, self-directed, and imaginative (Gray 2008). For each of these aspects, we demonstrate how an iterative process of development and formative testing improved several museum exhibits, engendering more playful learning experiences for visitors. We focus on the assessment element of the design-test process, offering in detail
This research investigated gender equitable exhibit development by enhancing a geometry exhibit with several female-friendly design features and analyzing video data to determine the effects on girls' engagement and social interactions with their caregivers. The findings suggest that incorporating several female-friendly design features leads to significantly higher engagement for girls (evidenced by greater attraction and time spent). This study also looked for any unanticipated negative effects for boys after incorporating the female-friendly design features.
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
This study evaluated a 2-week residential program aimed at enhancing the science interest and persistence of high-achieving 8th-grade girls. Questionnaires were administered to 38 program participants (14 of whom were of minority ethnicity) and 173 applicants who did not attend the program, at 3 time points: preprogram, 1 year postprogram, and 4 years postprogram. Outcomes, measured postprogram, included science self-concept and interest, persistence and aspirations in science, science activities, science course-taking in high school, and plans for a science college major. There was no main

The National Science Education Standards [National Research Council (1996) National science education standards. Washington, DC: National Academy Press] recommend that students understand the apparent patterns of motion of the sun, moon and stars by the end of early elementary school. However, little information exists on students’ ability to learn these concepts. This study examines the change in students’ understanding of apparent celestial motion after attending a planetarium program using kinesthetic learning techniques. Pre- and post-interviews were conducted with participants from seven

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
