Current empirical research in science and technology studies provides new and different views of science and scientists that contrast markedly with the mythical views that underlie many curricular efforts geared toward increasing scientific literacy. If descriptions of science and scientists that emerge from science and technology studies are legitimate, considerable implications arise for educational aims guiding science instruction, learning experiences directed toward those educational aims, and resources that support those learning experiences and educational aims. In this paper, we (a)
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

Children often learn new problem-solving strategies by observing examples of other people's problem-solving. When children learn a new strategy through observation and also explain the new strategy to themselves, they generalize the strategy more widely than children who learn a new strategy but do not explain. We tested three hypothesized mechanisms through which explanations might facilitate strategy generalization: more accurate recall of the new strategy's procedures; increased selection of the new strategy over competing strategies; or more effective management of the new strategy's goal
The World Congress of Science Producers is an annual event of leading broadcasters and independent science producers from around the world. This year's congress is being planned and osted by WGBH. For this Congress, WBGH will add two new dimensions to the meeting: 1) involve working scientists in the meeting to increase the dialogue and contact between broadcast journalists and scientists, and 2) partially support attendance by individuals who are either are considering entering science journalism or are newly involved in the field. Sessions that include scientists include: an exploration of the most important science stories that journalists should be covering, an in-depth analysis of a specific science issue, a discussion of ethical issues related to genome research, legal issues related to science in the courts, an examination of coverage of science vs. pseudo-science, and visualization of science.
This Phase I SEPA proposal supports a consortium of science and education partners that will develop System Dynamics (SD) computer models to illustrate basic health science concepts. The consortium includes Oregon Health Sciences University (OHSU), Portland Public Schools (PPS), Saturday Academy, and the Portland VA Medical Center. SD is a computer modeling technique in which diagrams illustrate system structure and simulations illustrate system behavior. Desktop computers and commercial software packages allow SD to be applied with considerable success in K-12 education. NSF grants to Portland Public Schools have trained over 225 high school teachers in Portland and surrounding areas. Two magnet programs have been established with an emphasis on systems and at least five other schools offer significant systems curriculum. Major components of this project include (1) Annual summer research internships at OHSU for high school teachers and high school students, (2) Development of SD models relevant to each research project, (3) Ongoing interactions between high school science programs and OHSU research laboratories, (4) Development of curriculum materials to augment the use of the SD model in the high school classroom or laboratory setting, and (5) Development of video materials to support the classroom teacher. Content will focus on four fundamental models: linear input/exponential output, bi-molecular binding (association/dissociation), population dynamics, and homeostasis. Each of these models is very rich and may be extended to a broad variety of research problems. In addition these models may be combined, for example to illustrate the effect of drugs (binding model) on blood pressure (homeostasis model). System Dynamics is an exemplary tool for the development of materials consistent with National Science Education Standards. SD was specifically developed to emphasize interactions among system structure, organization, and behavior. Students use these material as part of inquiry-based science programs in which the teacher serves as a guide and facilitator rather than the primary source of all content information; technical writing by students is also encouraged. Finally, these SD materials will provide a coherent body of work to guide the ongoing professional development of the classroom science teacher.
