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 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
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

Research suggests that parents are effective at scaffolding their children's learning to help them become self-regulated problem solvers. Yet little is known about parents' effectiveness at assisting their children with problems that parents find unfamiliar and, thus, do not have at hand either the solution or strategies that a novice child could profitably implement. In this study, 20 dyads of parents and their preadolescent children spent 45 min solving a scientific reasoning problem that entailed generating and interpreting a series of experimental trials to understand the causal structure

This longitudinal research used a sociocultural perspective to examine planning competence in the everyday experiences of European American and Latino children from 7 to 9 years of age. Data on children's participation in planning their activities outside of school, parental expectations about children's planning competence, and children's planning in the classroom were collected yearly from Grades 2 to 4 from 140 children and their mothers, and the children's teachers. Results indicate that decision-making practices and parental expectations change with development and vary by ethnicity
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

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

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
An important challenge in urban science education is finding ways to engage all students in the learning of science. However, research in this area has consistently shown that around middle school student engagement in science wanes. Using critical ethnographic methods this study reveals how students cultivate a sense of ownership in an informal science video project. Student ownership of what they they learn plays an important role in how they engage in the learning environment. In this study ownership is characterized by five themes, and the notion of student ownership science is challenged
