The Accuracy and Consistency of a Series of IRT True Score Equatings     

Deping Li  Yanlin Jiang  Alina A. von Davier 《Journal of Educational Measurement》2012,49(2):167-189

This study investigates a sequence of item response theory (IRT) true score equatings based on various scale transformation approaches and evaluates equating accuracy and consistency over time. The results show that the biases and sample variances for the IRT true score equating (both direct and indirect) are quite small (except for the mean/sigma method). The biases and sample variances for the equating functions based on the characteristic curve methods and concurrent calibrations for adjacent forms are smaller than the biases and variances for the equating functions based on the moment methods. In addition, the IRT true score equating is also compared to the chained equipercentile equating, and we observe that the sample variances for the chained equipercentile equating are much smaller than the variances for the IRT true score equating with an exception at the low scores.  相似文献   

International trends in health science librarianship: part 1 - the English speaking world     

Browne R  Lasserre K  McTaggart J  Bayley L  McKibbon A  Clark M  Perry GJ  Murphy J 《Health information and libraries journal》2012,29(1):75-80

This is the second in a series of articles exploring international trends in health science librarianship in the first decade of the 21st century. The invited authors were asked to reflect on developments in their country - viz. Australia, Canada, New Zealand and the United States. Future issues will track trends in Northern Europe, the Nordic countries, Southern Europe and Latin America. JM.  相似文献

Measuring patrons' technology habits: an evidence-based approach to tailoring library services     

Jin Wu  Amy J. Chatfield  Annie M. Hughes  Lynn Kysh  Megan Curran Rosenbloom 《Journal of the Medical Library Association》2014,102(2):125-129

Librarians continually integrate new technologies into library services for health sciences students. Recently published data are lacking about student ownership of technological devices, awareness of new technologies, and interest in using devices and technologies to interact with the library. A survey was implemented at seven health sciences libraries to help answer these questions. Results show that librarian assumptions about awareness of technologies are not supported, and student interest in using new technologies to interact with the library varies widely. Collecting this evidence provides useful information for successfully integrating technologies into library services.  相似文献   

Evidence‐Based Teaching in Higher Education: Application to Counselor Education          下载免费PDF全文

Krista M. Malott  K. Hridaya Hall  Angela Sheely‐Moore  Megan M. Krell  LeeAnn Cardaciotto 《Counselor Education & Supervision》2014,53(4):294-305

The authors examined best practices in university‐level teaching, as premised on the evidence‐based teaching (EBT) literature found in fields external to counselor education. Findings were reported in relation to 3 areas: developing an effective learning environment, structuring intentional learning experiences, and assessing teaching effectiveness. Implications regarding the training of doctoral‐level counselor educators using EBT practices are discussed.  相似文献

The dark side of social support: Understanding the role of social support,drinking behaviors and alcohol outlets for child physical abuse     

Bridget Freisthler  Megan R. Holmes  Jennifer Price Wolf 《Child abuse & neglect》2014

The purpose of this study is to examine how parental drinking behavior, drinking locations, alcohol outlet density, and types of social support (tangible, emotional, and social companionship) may place children at greater risk for physical abuse. Data on use of physical abuse, drinking behaviors, types of social support, social networks, and demographic information were collected via telephone interviews with 3,023 parent respondents in 50 cities in California. Data on alcohol outlet density were obtained by the California Department of Alcoholic Beverage Control. Multilevel Poisson models were used to analyze data for the drinking levels in the entire sample and dose-response drinking models for drinkers. Social companionship support was related to more frequent use of physical abuse. Having a higher percentage of social companionship support network living within the neighborhood was related to more frequent physical abuse in the full sample. This relationship was moderated by on-premise alcohol outlet density. With regards to drinking behaviors, drinking behaviors from ex-drinkers to frequent heavy drinkers used physically abusive parenting practices more often than lifetime abstainers. The dose-response models show that each additional drinking event at a bar or home/party was related to more frequent use of physical abuse. Practitioners working with parents who abuse their children should be aware that not all social support is beneficial. Findings build evidence that child maltreatment is influenced by the interaction between individual and ecological factors.  相似文献   

Three Contemporary Dilemmas for Rural Superintendents     

Aimee Howley  Megan Eliason Rhodes  Jacqueline J. Yahn 《Peabody Journal of Education》2014,89(5):619-638

The school district is the fundamental administrative unit of schooling in the United States and the superintendent the lead official. The nature and the challenges of this position, however, vary across the landscape. Because most superintendents lead rural districts, the challenges facing those districts are the ones that typically bedevil the superintendency overall (perhaps a surprising thought to many readers). From this vantage, we theorize such challenges overall, and illustrate the theory with three episodes: (1) the continuing threats of school and district consolidation; (2) the arrival of ethnic diversity in previously all-White rural places; and (3) the leasing of school lands for mining, with a focus on hydraulic fracturing (“fracking”).  相似文献
