Abstract: The overarching goal of the Science, Technology, Engineering, and Mathematics (STEM) Education Initiative is to foster effective STEM teaching and learning throughout the educational system at the local, state, and national levels, thereby producing science literate citizens and a capable STEM workforce. To contribute to achieving this goal, we have assembled six food science demonstrations for use at all educational levels and have presented these lessons to students at the elementary through higher education levels. The focus of this article is to share these food science demonstrations and our experiences using them so that others can use them for engaging students in STEM disciplines, through food science, at any educational level. Featured demonstrations include: (1) liquid nitrogen ice cream: a matter of changing phases, (2) seeing our senses work together, (3) whipping up the cream, (4) milk versus dark: what is the difference?, (5) counting calories by burning them, and (6) culinary spherification: the wonders of cross‐linking. Overall, our experience with using these demonstrations has been very positive. Students appear engaged in the learning process and love to consume the demonstration end products. Downloadable handouts containing demonstration details for each demonstration are available as supporting information. 相似文献

In interpersonal relationships characterized by aggression, the negotiation of conflict is especially significant. The present study examined the conflict management strategies used by 31 individuals who had experienced verbal and/or physical aggression during conflicts with their partners. Sillars’ (1986) conflict tactics coding system was used as a framework to analyze 960 pages of transcribed data. The results of this deductive content analysis indicated that the participants reported using primarily Distributive conflict strategies. Analytic induction was also used to interpret nonverbal forms of conflict management, revealing three common tactics: crying, nonverbal avoidance, and aggression. Implications for using these conflict strategies in interpersonal relationships characterized by aggression are discussed. 相似文献

In 1713, the scientific instrument-maker Jakob Leupold published designs for three machines were the first attempt to design machinery with internal moving parts that replaced human agency in creating original images. This paper first analyzes his text and engravings in order to explain how he proposed to do this, given contemporary materials and command of physical forces. Next, it characterizes the devices as a transition from concepts of incision to concepts of mirroring, taken as models of the history of mechanical reproduction. And finally, Leupold’s replacement of the sighting grid with differential gears points to a set of problems appearing in contemporary philosophy represented in Rococo artistic production of this period as well. Taking the proposed devices in context, they help to theorize the complex notions of creative activity in Rococo visual culture. Taken as an episode in the history of communications, they instance the development of conceptions of personhood and of physical forces at stake in the invention of automated media. 相似文献

This study is the first to provide best practices exclusively for communication about crises that involve issues of culture, ethnicity, and/or race from expert crisis managers' perspectives. Using complexity theory as a framework, this study provides an in-depth, theoretically grounded understanding of managing issues and crises involving culture, ethnicity and/or race through the experiences of 34 senior crisis communicators. Complex insider perspectives suggest that responsibility for crisis management must move beyond any managerial bias to become more organic, normative, inclusive, and community spirited. First, issues and crises involving culture, ethnicity, and/or race are defined, laying a foundation for future theory development on ways these issues can become or exacerbate crises. Second, research participants’ stories coalesce to produce best practices and a useful decision-making framework for practical application in organizations. 相似文献

The medical education literature is growing, and the result is not only greater knowledge, but an increasing complexity in locating quality evidence-based information. In 2008, eight librarians partnered with the Association of American Medical Colleges to research, conceptualize, and build an online module to develop medical educators’ search skills. Developing an online instructional module is a time-consuming, multi-stage process requiring the expertise of content, technical, and design specialists working in concert. Many lessons were learned, including the power of collaborative tools; the benefits of including specialists, such as graphic designers; the benefit of thoroughly surveying existing resources; and the importance of choosing technology wisely. 相似文献

This article reviews studies from various disciplines on plagiarism as a cross-cultural issue and examines cultural, educational, and linguistic factors that may influence the textual borrowing practices of international students. The reasons international students may employ inappropriate source use are complex and attempts to address and combat plagiarism in higher education must take into account multiple factors. Recommendations are made for ways in which academic libraries can assist international students with understanding plagiarism through orientations, instruction, reference service, and web-based guides and tutorials. 相似文献

This study explores whether the religious background of students affects their opinions about and attitudes to engaging with scientific explanations of the origins of the universe and of life. The study took place in four English secondary schools representing three different contexts (Christian faith-based; non-faith with majority Muslim catchment; and non-faith, mixed catchment). It comprised questionnaires and focus groups with over 200 students aged 14–16, supplemented by teacher interviews. The analysis approach was informed by grounded theory and resulted in the development of an engagement typology, which has been set in the context of the cross-cultural border crossing literature. It divides students into categories depending on both the nature and amount of engagement they were prepared to have with the relationship between science and religion. The model takes into account where students sit on four dimensions. These assess whether a student's preferred knowledge base is belief-based or fact-based; their tolerance of uncertainty (do they have a need for resolution?); their open mindedness (are they unquestioning or inquiring?); and whether they conceptualise science and religion as being in conflict or harmony. Many Muslim students resisted engagement because of conflicting religious beliefs. Teachers did not always appreciate the extent to which this topic troubled some students who needed help to accommodate clashes between science and their religious beliefs. It is suggested that increased appreciation of the complexity represented by their students can guide a teacher towards an appropriate approach when covering potentially sensitive topics such as the theory of evolution. 相似文献

Academic productivity and research funding have been hot topics in biomedical research. While publications and their citations are popular indicators of academic productivity, there has been no rigorous way to quantify co-authors’ relative contributions. This has seriously compromised quantitative studies on the relationship between academic productivity and research funding. Here we apply an axiomatic approach and associated bibliometric measures to revisit a recent study by Ginther et al. (Ginther et al., 2011a, Ginther et al., 2011b) in which the probability of receiving a U.S. National Institutes of Health (NIH) R01 award was analyzed with respect to the applicant's race/ethnicity. Our results provide new insight and suggest that there is no significant racial bias in the NIH review process, in contrast to the conclusion from the study by D. K. Ginther et al. Our axiomatic approach has a potential to be widely used for scientific assessment and management. 相似文献
