The Use of the Analysis of Co‐variance in Educational Research: panacea or pitfall for the unwary?     

Robert Lambourne  Kevin Wheldall 《Educational studies》1979,5(1):43-51

The theory underlying the analysis of covariance is outlined and certain common misuses delineated. The technique is severely limited in its applications while invalid applications may lead to false inferences. It is shown that it cannot make non‐experimental designs experimental and that invalid assumptions regarding the slope of the regression lines may also lead the educational researcher astray.  相似文献   

Effectiveness of fieldwork at an information desk: A prototype for academic library-library school collaboration     

Diane Nahl  Assistant Professor  Ann Coder  Head  Janet Black  Reference Librarian  Margie Smith  Referrence Librarian  Information Desk Coordinator 《The Journal of Academic Librarianship》1994,20(5-6)

This article presents a model of how academnic libraries and schools of library and information studies (LIS) may collaborate to provide useful educational experiences to LIS students and reliable reference service to library users. LIS students staff an information desk for s fieldwork component of a basic reference course. Research shows that the students provide accurate services at the desk.  相似文献

How Niche Magazines Survive and Thrive Through an Industry in Turmoil     

Kevin M. Baker 《Publishing Research Quarterly》2018,34(3):407-416

In recent years, many general-interest magazine publishers have had problems maintaining stability. What can these publications learn from smaller, niche titles that have  remained successful through the same industry changes? This paper will examine three major strengths for niche magazines that general-interest magazine publishers lack: their reader devotion, their careful approaches to digitalization, and their use of paid digital content. These strengths are analyzed in three case studies from different sub-genres of niche publishing: a city magazine, a luxury product magazine, and a hobby magazine. This paper offers practical suggestions general-interest magazines can implement. Looking at the successful practices suggests the potential to address industry-wide problems and to potentially yield more stable magazine publishing environments.  相似文献

Judging the Need for and Value of DDA in an Academic Research Library Setting     

Kevin W. Walker  Michael A. Arthur 《The Journal of Academic Librarianship》2018,44(5):650-662

This article reports findings from a multiphase analysis of demand-driven acquisitions (DDA) within the academic research library setting. Evaluating local collections within the context of Trueswell's (1969) often-cited 80/20 Rule, phase one of this study illustrates the deficiencies of a just-in-case approach to building library collections. Following from this, phase two evaluates the viability of DDA as the just-in-time collection-building solution librarians have sought as an answer to low-use titles that plague most academic library collections. Supported by 16?months of data, this study scrutinizes the comparative value of DDA against traditionally acquired titles along two key dimensions—the subject-matter profile of purchases and their overall usage levels. Further, the concept of a utility as value paradigm, as well as a purchase-use equilibrium for library collections, provide a theoretical framework in which the relative value of DDA is assessed. From a content, or subject-matter, perspective, this study finds negligible deviation in those purchasing patterns associated with DDA when compared with traditionally-acquired materials. At the same time, DDA titles experience much higher levels of use and are, therefore, associated with markedly lower cost-per-use figures and greater overall value.  相似文献

Experimental evidence for diagramming benefits in science writing     

Brendan Barstow  Lisa Fazio  Christian Schunn  Kevin Ashley 《Instructional Science》2017,45(5):537-556

Arguing for the need for a scientific research study (i.e. writing an introduction to a research paper) poses significant challenges for students. When faced with these challenges, students often generate overly safe replications (i.e. fail to find and include opposition to their hypothesis) or in contrast include no strong support for their hypothesis (i.e. relevant, valid evidence). How can we support novice scientists in generating and defending high quality hypotheses? A long history of research supports the affordances provided by structured representations of complex information. More recently, argument diagramming has gained traction in instruction for philosophy, social studies, and law. However, its effectiveness for supporting students in science is relatively untested. The purpose of the current study was to test the effectiveness of a simple argument diagram optimized for supporting students’ research writing in psychology. Two groups of undergraduate students in research methods lab courses were randomly assigned to diagramming support or no support. In the research papers, those given diagramming support were more likely to argue for an appropriately ‘risky’ hypothesis and wrote more about the relevance and validity of cited studies. Some of these gains show signs of transfer to a second paper written later in the course that did not require use of the diagramming tool.  相似文献   

Further evidence for the efficacy of an evidence-based,small group,literacy intervention program for young struggling readers

Abstract

An earlier series of pilot studies and small-scale experimental studies had previously provided some evidence for the efficacy of a small group early literacy intervention program for young struggling readers. The present paper provides further evidence for efficacy based on a much larger sample of young, socially disadvantaged, at-risk readers. The participants comprised 14 successive intakes of Year 1 and Year 2 students into small group remedial literacy intervention programs hosted by two charitably run tutorial centres. In each semester, over the years 2005–2011, eight students (on average) attended each centre for one hour, for four days per week, for 15 weeks. Pre- and post-test assessment data on eight measures of early literacy performance were available on up to 194 students who completed the program. Substantial and statistically significant gains were evident on all literacy measures with large effect sizes. These results provide further evidence for the efficacy of the small group literacy intervention program.  相似文献
