We report a multidimensional test that examines middle grades teachers’ understanding of fraction arithmetic, especially multiplication and division. The test is based on four attributes identified through an analysis of the extensive mathematics education research literature on teachers’ and students’ reasoning in this content area. We administered the test to a national sample of 990 in‐service middle grades teachers and analyzed the item responses using the log‐linear cognitive diagnosis model. We report the diagnostic quality of the test at the item level, mastery classifications for teachers, and attribute relationships. Our results demonstrate that, when a test is grounded in research on cognition and is designed to be multidimensional from the onset, it is possible to use diagnostic classification models to detect distinct patterns of attribute mastery. 相似文献

Audience measurement data are increasingly central to what many media corporations produce, yet much of these data are inaccessible to scholars. I therefore argue that cultural studies is in need of an audience studies revival. Fan studies continues at strength, but a wider range of audience studies is required to counter and to interrogate the occasional proclamations that companies such as Netflix, Facebook, and Google share with us about audiences and users. 相似文献

Assessment,and the literacy practices of trainee PCET teachers 总被引:1,自引:0,他引:1
Jonathan Tummons 《International Journal of Educational Research》2008,47(3):184-191
Drawing on concepts of learning as socially situated within communities of practice and of literacy as social practice (the New Literacy Studies), this paper seeks to explore the assessment practices of a part-time teacher training course for teachers working in the post-compulsory education and training sector. This paper argues that the ways in which student teachers make sense of the assessment requirements of their course is not related to their prior experiences as students or as teachers, contradicting notions of transferable study skills. This paper also posits a conceptual framework for exploring the assessment process that seeks to reconcile assessment and pedagogy with the community of practice model. 相似文献

A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC2010 mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems. 相似文献

Experience gained in the construction of the world's first Geographical Information Systems tutor, ARCDEMO, emphasised the importance of accommodating different learning strategies. ARCDEMO, while highly successful, suffered from static graphical displays, a single pre-determined access path, and an overall design which restricted its scope in use. The Geographical Information System Tutor (GIST) was developed to address these problems using Apple's object-orientated HyperCard software. GIST incorporates a 'point-and-click' interface with graphical cues to initiate operations which include animated demonstrations, step-by-step illustrative graphics and graphical displays capable of user modification. The system was designed with two alternative access modes, serial or browsing , to allow different classes of user to work through the material in their preferred fashion. The use of GIST in undergraduate and short course teaching has shown how users respond well to the interface and find graphical explanations easy to follow. 相似文献
