The notion that science is unified in one way or another dates back at least to Aristotle, though unity claims since then have been diverse and va riously motivated. By way of introduction to the modern discussion of unity, disunity, and integration, in this first section we examine five historical attempts to unify knowledge: Aristotle’s metaphysical and hierarchical unity; the Enlightenment project of the French Encyclopedists; the systematic unity of Naturphilosophen Lorenz Oken; the methodological unity of the Vienna School’s Encyclopedia of Unified Science; and finally, the organizational
This article takes an anti-essentialist approach to the gendered construction of the science curriculum and its exclusivity. Drawing on post-structuralist theory, it examines the student subject positions that are generated within the dominant discourses and practices of curriculum science. A critical discourse analysis of student interview talk demonstrates the importance of both gender and ethnicity in the production of, or rejection of, scientist identities. While hegemonic masculinity can provide comfortable scientist identities for some males, femininity is less compatible with physical
Building on and extending existing research, this article proposes a 4-phase model of interest development. The model describes 4 phases in the development and deepening of learner interest: triggered situational interest, maintained situational interest, emerging (less-developed) individual interest, and well-developed individual interest. Affective as well as cognitive factors are considered. Educational implications of the proposed model are identified.
This chapter draws attention to the self-regulatory skills that students use in informal learning settings. Formal and informal learning settings are defined as complementary learning environments and it is pointed out that students differ with respect to the learning environments they find conducive to learning. It is suggested that the goals students set for themselves when learning in an informal learning context are different from the goals they set for themselves in a formal learning context. Furthermore, it is speculated that students attend to different clues and select different self
Positive affect systematically influences performance on many cognitive tasks. A new neuropsychological theory is proposed that accounts for many of these effects by assuming that positive affect is associated with increased brain dopamine levels. The theory predicts or accounts for influence of positive affect on olfaction, the consolidation of long-term (ie. episodic) memories, working memory, and creative problem solving. For example, the theory assumes that creative problem solving is improved, in part, because increased dopamine release in the anterior cingulate improves cognitive

This study investigated the effectiveness of a combined museum and classroom intervention project on science learning in low-income children. The focus of the program was on children's content knowledge and concept complexity. Thirty children were in the experimental group. A control group of 18 children visited literacy and social studies exhibits at the museum. Results indicate that children in the experimental group learned content knowledge about the components of bubbles and the definition of a current. Although children in the experimental group exhibited more complex concepts about

Investigates home influence on science education by referring to a project in which very simple science activities were given out by the teacher at school to be performed at home by the primary pupils with their families.
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
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'
