Best Practice in Middle-School Science

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

Quantifying the interdisciplinarity of scientific journals and fields     

F.N. Silva  F.A. Rodrigues  O.N. Oliveira  L. da F. Costa 《Journal of Informetrics》2013,7(2):469-477

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   

Level of deprivation does not affect degree of discounting in pigeons     

Luís Oliveira  Amanda L. Calvert  Leonard Green  Joel Myerson 《Learning & behavior》2013,41(2):148-158

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   

Viscoelasticity of blood and viscoelastic blood analogues for use in polydymethylsiloxane in vitro models of the circulatory system     

Laura Campo-Dea?o  Roel P. A. Dullens  Dirk G. A. L. Aarts  Fernando T. Pinho  Mónica S. N. Oliveira 《Biomicrofluidics》2013,7(3)

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

Teams’ innovation: getting there through knowledge sharing and absorptive capacity     

Carla Curado  Mírian Oliveira  Antonio Carlos Gastaud Maçada  Felipe Nodari 《知识管理研究与实践》2017,15(1):45-53

This study addresses the contribution of knowledge sharing behaviour and absorptive capacity to innovation at team level. Although the hypotheses reflect the dominant literature, the study’s novelty lies in the data collected from several industries in Portugal, avoiding possible industry bias. Relationships are tested outside sectors where traditionally team effects are studied, for example healthcare. Data were collected from 141 employees working in organizational teams, excluding top management teams, which are often the object of research addressing phenomena leading to innovation. There is no evidence in support of organizational size effect, team’s geographic concentration effect or gender effect. However, team tenure duration is positively related to increased knowledge sharing, that is, recent teams do not share as much knowledge as older ones. Structural Equation Modelling was used to test the mediation effect of absorptive capacity between individual knowledge sharing behaviour and team innovation. Evidence in support of full mediation was found.  相似文献
