This study examines how three elementary teachers refer to pictorial models (photographs, drawings, and cartoons) during science read-alouds. While one teacher used realistic photographs for the purpose of visually verifying facts about crystals, another employed analytical diagrams as heuristic tools to help students visualize complex target systems (rainbow formation and human eye functioning). Another teacher used fictional cartoons to engage students in analogical storytelling, communicating animal camouflage as analogous to human “blending in.” However, teachers did not always explicitly convey the representational nature of pictorial models (analog and target as separate entities). It is argued that teachers need to become more aware of how they refer to pictorial models in children’s science books and how to promote student visual literacy. 相似文献

Using socio-ecological theory, this study explores best practice (educational practices correlated with higher student performance) in middle-school science. Seven schools with consistently higher student performance were compared with three demographically similar, average-performing schools. Best practice included instructional approaches (relevance and engagement, inquiry, differentiated instruction, collaborative work, moderate amounts of homework, and integration of language literacy and science) and administrative practices (nurturing a climate of opportunity to succeed in science, offering professional development based on data and dialogue, engaging teachers in standards-based curriculum revision and alignment, and recruiting the right fit of teacher). It is argued that best practice entails multiple levels of teaching and administrative praxis that together form a school-wide socio-ecological system conducive to higher performance. 相似文献

ABSTRACT This article reports a graduate level program designed to facilitate inquiry into the integration of technology in schools (ITS). The ITS Process is described within the frame of insights related to teacher developmental readiness for change. The process of teacher education is viewed as change within the dialectic of ideas and actions built around the dynamics of reflection, experience, modeling, planning, and a return to reflection. Four domains of inquiry, the building of a community of thinkers, a broad base of collaboration, and transdisciplinary study are presented as the foundation of the ITS Process. A four semester process of study and the concomitant curriculum are outlined, and strategies for facilitating the process are explored. 相似文献

Librarians at the University of Florida Health Science Center Libraries partnered with faculty to promote awareness of and access to research on women's health and sex and gender resources in an outreach project funded by the National Library of Medicine and the National Institutes of Health Office of Research on Women's Health. The project featured elements that facilitated cross-disciplinary collaboration (using CoLAB Planning Series®, or CoLABs), instruction to various groups (including faculty, undergraduate students, graduate students, and professional students), collection development, and information dissemination. Librarians leveraged existing partnerships with faculty and built new ones. Success in this project demonstrates that libraries can partner effectively with their faculty on emerging trends and new initiatives. 相似文献

There is an overall perception of increased interdisciplinarity in science, but this is difficult to confirm quantitatively owing to the lack of adequate methods to evaluate subjective phenomena. This is no different from the difficulties in establishing quantitative relationships in human and social sciences. In this paper we quantified the interdisciplinarity of scientific journals and science fields by using an entropy measurement based on the diversity of the subject categories of journals citing a specific journal. The methodology consisted in building citation networks using the Journal Citation Reports® database, in which the nodes were journals and edges were established based on citations among journals. The overall network for the 11-year period (1999–2009) studied was small-world and followed a power-law with exponential cutoff distribution with regard to the in-strength. Upon visualizing the network topology an overall structure of the various science fields could be inferred, especially their interconnections. We confirmed quantitatively that science fields are becoming increasingly interdisciplinary, with the degree of interdisplinarity (i.e. entropy) correlating strongly with the in-strength of journals and with the impact factor. 相似文献

Two experiments tested the effects of food deprivation on discounting in pigeons. An adjusting-amount procedure was used to estimate the subjective value of food at delays ranging from 1 to 24 s. Experiment 1 compared pigeons’ discounting of delayed food reinforcers at 75 %–80 % and 90 %–95 % of free-feeding weight. Experiment 2 compared discounting under 1- and 23-h food deprivation. In both experiments at both deprivation levels, discounting was well described by the hyperboloid discounting function. No systematic effect of level of deprivation on degree of discounting was observed in either experiment. This finding is consistent with the view that pigeons’ choices are controlled by the relative, rather than the absolute, value of reinforcers. 相似文献

The non-Newtonian properties of blood are of great importance since they are closely related with incident cardiovascular diseases. A good understanding of the hemodynamics through the main vessels of the human circulatory system is thus fundamental in the detection and especially in the treatment of these diseases. Very often such studies take place in vitro for convenience and better flow control and these generally require blood analogue solutions that not only adequately mimic the viscoelastic properties of blood but also minimize undesirable optical distortions arising from vessel curvature that could interfere in flow visualizations or particle image velocimetry measurements. In this work, we present the viscoelastic moduli of whole human blood obtained by means of passive microrheology experiments. These results and existing shear and extensional rheological data for whole human blood in the literature enabled us to develop solutions with rheological behavior analogous to real whole blood and with a refractive index suited for PDMS (polydymethylsiloxane) micro- and milli-channels. In addition, these blood analogues can be modified in order to obtain a larger range of refractive indices from 1.38 to 1.43 to match the refractive index of several materials other than PDMS. 相似文献

In this paper I examine some issues raised by conspicuous displays of religiosity in sports. In particular, important questions have been occasioned by the relatively recent pronouncements and behavior of a celebrated evangelical Christian athlete in American professional football. I explain reasons why some find such conspicuous piety worrisome. I raise concerns related to the nature of sport, consistency, divisiveness, trivialization, and religious diversity. After discussing objections to exclusivist forms of religion, especially theistic religions, I focus on how religious beliefs should be held. I present what I call the Basic Argument from Religious Disagreement, whose conclusion claims that religious beliefs ought to be held fallibly, rather than confidently or with certainty. Fallible religious belief has important and valuable consequences, overall and in the specific context of sports. Celebrated athletes have strong reasons to hold religious beliefs fallibly and, if they claim to be role models, they may have epistemic responsibilities as well as moral responsibilities. 相似文献
