The authors of this article discuss three pedagogical approaches, learning community, community of practice and community learning, and analyse their significance for knowledge acquisition and construction in higher education. The authors also explore the roles of technology in creating adequate environments for educators to implement teaching practices supported by these approaches and explain, through an illustrative course example, how technology and teaching methods can be used together to promote interaction among learners and help them achieve course goals.
This paper uses a possible selves theoretical framework to examine whether and how adolescent girls' images of themselves as future scientists change during their transition from high school to college. Forty-one female high school graduates from diverse ethnic and socioeconomic backgrounds, who had enrolled in an intensive math and science program while in high school, participated in interviews focused on their perceptions of factors that influenced their career plans over time. Participants suggested that career-related internships and intensive academic programs, especially those that
Robotic Autonomy is a seven-week, hands-on introduction to robotics designed for high school students. The course presents a broad survey of robotics, beginning with mechanism and electronics and ending with robot behavior, navigation and remote teleoperation. During the summer of 2002, Robotic Autonomy was taught to twenty eight students at Carnegie Mellon West in cooperation with NASA/Ames (Moffett Field, CA). The educational robot and course curriculum were the result of a ground-up design effort chartered to develop an effective and low-cost robot for secondary level education and home use
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 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
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
