10,000 Libraries, 4 Years: A Large-Scale Study of E-Book Usage and How You Can Use the Data to Move Forward     

Michael Levine-Clark  Kari Paulson  Paul Moeller 《期刊图书馆员》2015,68(1-4):262-268

Michael Levine-Clark and Kari Paulson examine 2013 worldwide usage data for ebrary and E-book Library (EBL) covering hundreds of thousands of titles. They examine usage patterns across academic libraries globally and establish benchmarks useful to libraries and consortia for local planning. Sessions versus availability, the use of higher-quality e-books, broad disciplinary differences, performance relative to predicted use, and level of immersion are considered. Levine-Clark is in the process of analyzing ebrary and EBL data for a forthcoming white paper, and this presentation and associated discussion will inform the development of that study.  相似文献

A pedagogy of belonging: troubling encounters with ethnic and religious difference     

Kathryn Edgeworth  Ninetta Santoro 《Cambridge Journal of Education》2015,45(4):415-426

Understanding the construction of belonging, and how unbelonging might be troubled, is critical work. For schools in many parts of the world one of the many challenges of globalisation is the task of teaching with, and for, ethnic and cultural diversity. This paper examines the exclusionary practices of teaching that construct ethnic and religious minority students in states of unbelonging. These practices are due, in part, to teachers’ failure to really know their students. Alongside this argument, discourses of belonging in rural schools that speak to possibilities for everyday place-sharing for ethnic and religious minority students are examined. Simple and common moments of mutual recognition and understanding speak to the possibilities for belonging that are opened up in everyday relations of knowing. The implications of these ideas for teachers and teacher education in what is framed as a ‘pedagogy of belonging’ are considered.  相似文献

Identity Matching to Scientists: Differences that Make a Difference?     

Hanne Moeller Andersen  Lars Brian Krogh  Eva Lykkegaard 《Research in Science Education》2014,44(3):439-460

Students' images of science and scientists are generally assumed to influence their related subject choices and aspirations for tertiary education within science and technology. Several research studies have shown that many young people hold rather stereotypical images of scientists, making it hard for them to see themselves as future scientists. Adolescents' educational choices are important aspects of their identity work, and recent theories link individual choice to the perceived match between self and prototypical persons associated with that choice. In the present study, we have investigated images of scientists among the segment of the upper secondary school students (20 % of the cohort) from which future Danish scientists are recruited. Their images were rather realistic, only including vague and predominantly positive stereotypical ideas. With a particular Science-and-Me (SAM) interview methodology, we inquired into the match between self- and prototypical-scientists (N?=?30). We found high perceived similarity within a core of epistemological characteristics, while dissimilarities typically related to a social domain. However, combining interview data with survey data, we found no significant statistical relation between prototype match and aspirations for tertiary education within science and technology. Importantly, the SAM dialogue revealed how students negotiate perceived differences, and we identified four negotiation patterns that all tend to reduce the impact of mismatches on educational aspirations. Our study raises questions about methodological issues concerning the traditional use of self-to-prototype matching as an explanatory model of educational choice.  相似文献   

The Science of Pizza: The Molecular Origins of Cheese,Bread, and Digestion Using Interactive Activities for the General Public     

Amy C. Rowat  Daniel Rosenberg  Kathryn A. Hollar  Howard A. Stone 《Journal of Food Science Education》2010,9(4):106-112

Abstract: We describe a presentation on the science of pizza, which is designed for the general public including children ages 6 and older. The presentation focuses on the science of making and digesting cheese and bread. We highlight 4 major scientific themes: (1) how macromolecules such as carbohydrates and proteins are composed of atoms and small molecules; (2) how macromolecules interact to form networks in bread and cheese; (3) how microbes contribute to the texture of bread; and (4) how enzymes break down macromolecules during digestion. Using live demonstrations and interactive exercises with children in the audience, we provide simple explanations of the scientific principles related to these themes that are essential for understanding how to make pizza, and what happens when we eat it. This general approach can be adapted to a variety of informal and classroom settings focused on sharing the excitement of scientific discovery and understanding with students and the public.  相似文献   

Announcing the Engagement of Sudoku: An In‐Class Genetic Algorithm Game          下载免费PDF全文

Kathryn W. Ernstberger  M.A. Venkataramanan 《Decision Sciences Journal of Innovative Education》2018,16(3):185-196

This teaching brief describes an engaging, in‐class exercise that introduces genetic algorithms as well as advanced Excel functions and capabilities by modeling the familiar Sudoku puzzle. Student groups are first asked to manually solve a given puzzle and then translate that solution methodology to a spreadsheet model. This exercise can be used to build classroom community and as a launching point for the content area of genetic algorithms and the use of Evolutionary Solver.  相似文献   

Quantification of improvement in triathlon swimming performance by textile speedsuits     

Olaf Ueberschär  Axel Schleichardt  Laura Buchhop  Ina Fichtner  Thomas Moeller 《Sports Engineering》2018,21(4):379-388

To quantify swimwear-induced differences under triathlon-specific conditions, we compare the swimming performance, the metabolic cost, and the standardised passive drag of well-trained triathletes when wearing (1) five speedsuit models by different manufacturers from 2017, (2) usual swimming trunks/swimsuits (men/women), and (3) individually preferred competition trisuits. Because of the complexity of the underlying hydrodynamic and biomechanical effects, three separate experimental stages were realized, each with 6–12 well-trained short- and middle-distance triathletes (male and female, mean age 22?±?5 years) from the German national elite or junior elite level. All measurements were conducted on the basis of real athletes’ motion in the water to correctly account for all relevant effects, including skin and muscle vibrations. First, the athletes took part in a series of 100 m short-distance tests at maximal effort in a long-course pool to quantify swim-time differences in absolute terms. Second, the subjects completed multiple submaximal 400 m tests at 95% of their individual maximal speed in a swimming flume, with their swimwear-related differences in metabolic load being explored in terms of blood lactate and heart rate. Third, the passive drag of the triathletes was measured in the flume during a towing test under standardised conditions in velocity steps of 0.2 m/s within the triathlon-relevant range of 1.1–1.7 m/s. In all three test stages, the speedsuits exhibited performance advantages over trunks/swimsuits: in the 100 m maximal test, the mean swim time with speedsuits decreased by 0.99?±?0.30 s (????1.5%). During the 400 m submaximal flume test, the mean heart rate showed a reduction of 7?±?2 bpm (? ??4.0%), while the post-exercise blood lactate accumulation decreased by 1.0?±?0.2 mmol/L (? ??26.2%). Similarly, the passive drag in the towing test was lowered by 3.2?±?1.0 W (????6.9% as for normalised power and ??5.2% as for normalised force) for the speedsuits. Wearing speedsuits instead of usual trunks/swimsuits is shown to improve the swimming performance and to reduce the metabolic cost for well-trained triathletes under triathlon-specific test conditions. The reduction in passive drag of the passively towed athlete’s body due specific speedsuit surface textures seems to be only one reason for performance advantages: the effective reduction in muscular, soft tissue, and skin vibrations at the trunk and thighs during active propulsive motion of the swimmer seems to further contribute substantially.  相似文献   

School board decision-making and the elimination of sport participation fees     

Kathryn L. Heinze  Jennifer Zdroik 《Sport, Education and Society》2018,23(1):53-67

Public schools in the US are increasingly charging ‘pay-to-play’ fees for participating in sports. Although these fees can cause reductions in participation, particularly for children from lower-income families, pay-to-play has become a legitimate practice within the field of public education. This study examines what leads some school districts to abandon sport participation fees, despite the trend in adoption. In particular, using a qualitative, case study approach, we investigate why and how school districts eliminate pay-to-play. We found that the decision to terminate pay-to-play in the ‘Ellis’ district was shaped by the community culture and district leadership. Our findings are supported by data on surrounding school districts. This study contributes to the literatures on institutional change; privatization of health, sport and physical education; and school board decision-making. The findings also shed light on the local context of pay-to-play—a policy that has implications for social equity and youth health and wellness.  相似文献

Objective:Since concussion is the most common injury in ice hockey,the objective of the current study was to elucidate risk factors,specific mechanisms,and clinical presentations of concussion in men’s and women’s ice hockey.Methods:Ice hockey players from 5 institutions participating in the Concussion Assessment,Research,and Education Consortium were eligible for the current study.Participants who sustained a concussion outside of this sport were excluded.There were 332(250 males,82 females)athletes who participated in ice hockey,and 47(36 males,11 females)who sustained a concussion.Results:Previous concussion(odds ratio(OR)=2.00;95%confidence interval(95%CI):1.02‒3.91)was associated with increased incident concussion odds,while wearing a mouthguard was protective against incident concussion(OR=0.43;95%CI:0.22‒0.85).Overall,concussion mechanisms did not significantly differ between sexes.There were specific differences in how concussions presented clinically across male and female ice hockey players,however.Females(9.09%)were less likely than males(41.67%)to have a delayed symptom onset(p=0.045).Additionally,females took significantly longer to reach asymptomatic(p=0.015)and return-to-play clearance(p=0.005).Within the first 2 weeks post-concussion,86.11%of males reached asymptomatic,while only 45.50%of females reached the same phase of recovery.Most males(91.67%)were cleared for return to play within 3 weeks of their concussion,compared to less than half(45.50%)of females.Conclusion:The current study proposes possible risk factors,mechanisms,and clinical profiles to be validated in future concussions studies with larger female sample sizes.Understanding specific risk factors,concussion mechanisms,and clinical profiles of concussion in collegiate ice hockey may generate ideas for future concussion prevention or intervention studies.  相似文献
