Recent gender retheorisation has drawn on Mikhail Bakhtin's literary and linguistic theories of monoglossia and heteroglossia to reconcile seemingly contradictory gender discourses. Thus, girls/women and boys/men as they are biologically sexed might be discussed within a poststructural gender theory discourse that disconnects gender from the body. The concepts of gender monoglossia, gender heteroglossia and polyglossia have been applied here to empirical research into the construction of gendered leadership as it was seen to be done by one woman head teacher. The accounts of members of staff expose heteroglossia in the articulation of their understandings of gendered leadership beneath the construction of a monoglossic façade. They also reveal an understanding of polyglossic simultaneity as the head teacher is observed to ‘switch’ seamlessly between modes of doing gendered leadership depending on context and circumstances. There is also evidence of polyglossic simultaneity in the reports that might lead to the rejection and/or redefinition of gender theory discourses.  相似文献

ABSTRACT

This article explores some of the key impacts that Google and new technologies such as Web 2.0 have had on the way people see information and information professionals and presents the argument that much of what is typically seen as negative about Google is, in fact, positive.  相似文献

Search engine optimization, or the practice of designing a web site so that it rises to the top of the results page when users search for particular keywords or phrases, has become so prevalent on the modern web that it has a significant influence on Google search results. This article examines the techniques used by search engine optimization practitioners, the difference between “white hat” and “black hat” optimization tactics, and why it is important for library staff to understand these techniques and their impact on search engine results pages. It also looks at ways that library staff can help their users develop awareness of the factors that influence search results and how to better assess the quality and relevance of results listings.  相似文献

Previous research has demonstrated that cognitive test validities are generalizable and predictive of academic performance across situations. However, even after accounting for statistical artifacts (e.g., sampling error, range restriction, criterion reliability), substantial variability often remains around estimates of cognitive test–performance relationships suggesting the presence of additional moderators. In the present study, we examine the sources of institutional variation in Scholastic Aptitude Test (SAT) validity across a sample of 110 institutions. Institutional characteristics moderated the size of SAT validities, such that more selective schools and schools that emphasize traditional assessment techniques (i.e., school records, standardized tests) showed higher SAT validities while schools that were larger and where students demonstrated more financial need, schools that emphasized the usage of alternative assessment techniques (i.e., essays, letters of recommendations, extracurricular activities), and schools that enrolled higher percentages of historically disadvantaged minority students generally exhibited lower SAT validities. Future directions in the understanding of situational influences on SAT–grade point average validities are discussed.  相似文献

To design an effective computer science curriculum, educators require a systematic method of classifying the difficulty level of learning activities and assessment tasks. This is important for curriculum design and implementation and for communication between educators. Different educators must be able to use the method consistently, so that classified activities and assessments are comparable across the subjects of a degree, and, ideally, comparable across institutions. One widespread approach to supporting this is to write learning objects in terms of Bloom’s Taxonomy. This, or other such classifications, is likely to be more effective if educators can use them consistently, in the way experts would use them. To this end, we present the design and evaluation of our online interactive web-based tutorial system, which can be configured and used to offer training in different classification schemes. We report on results from three evaluations. First, 17 computer science educators complete a tutorial on using Bloom’s Taxonomy to classify programming examination questions. Second, 20 computer science educators complete a Neo-Piagetian tutorial. Third evaluation was a comparison of inter-rater reliability scores of computer science educators classifying programming questions using Bloom’s Taxonomy, before and after taking our tutorial. Based on the results from these evaluations, we discuss the effectiveness of our tutorial system design for teaching computer science educators how to systematically and consistently classify programming examination questions. We also discuss the suitability of Bloom’s Taxonomy and Neo-Piagetian theory for achieving this goal. The Bloom’s and Neo-Piagetian tutorials are made available as a community resource. The contributions of this paper are the following: the tutorial system for learning classification schemes for the purpose of coding the difficulty of computing learning materials; its evaluation; new insights into the consistency that computing educators can achieve using Bloom; and first insights into the use of Neo-Piagetian theory by a group of classifiers.  相似文献

Media Effectiveness in a Malaysian Park System   总被引:1,自引:0,他引:1  
Abstract

The effectiveness of three media formats (guides, booklets, and signs) were compared for use on a nature trail at Kinabalu Park, Malaysia. Based on a multiple-choice, cognitive test taken by 1,194 visitors, the guide treatment scores were significantly higher than the other media treatments. There was no difference between booklet and sign treatments, and all the media treatments scored higher than the control group (F 3,1190 = 173.76, α = .05). A second experiment compared only booklet and sign media. There was still no difference in effectiveness (Paired t test, t = 0.22, df = 566, p □ .05). The first language and educational backgrounds of visitors influenced media effectiveness. However, age, sex, residence, interest level, prior knowledge, and prior park visitation did not influence the relatively great effectiveness of the guide treatment. Other factors, such as cost, time, and numbers served, may justify use of media formats other than guides.  相似文献
