The development of any assessment should be an iterative and careful process. Ideally, this process is guided by a well-defined framework (see for example Downing in: Downing and Haladyna (eds) Handbook of test development, Lawrence Erlbaum Associates, Mahwah, 2006; Mislevy et al. in On the roles of task model variables in assessment design (CSE Technical Report 500), Educational Testing Service, Princeton, 1999; AERA et al. in Standards for educational and psychological testing, AERA, Washington, DC, 2004), but such a framework is not always available when the instrument to be developed is new or innovative. Frameworks for the development of traditional computer-based tests have been published and experimented with since the late 1990s, by which time CBT had already existed for more than a decade. In an earlier empirical pilot study, we described a new type of assessment for Dutch vocational education, called multimedia-based performance assessment (MBPA) (self-revealing reference 2014). This CBT uses multiple media formats and interactive tasks to measure skills that are currently measured by performance-based assessment. In conducting that pilot study, deficits in the existing literature made it difficult to ground all developmental steps in sound scientific theory. To remedy those deficits, this article presents and validates a framework for the design and development of MBPA, combining a search of the relevant literature from several subfields of educational assessment and consultation with assessment experts. The framework unites assessment development and multimedia development theory, focus solely on vocational education, and answers the call for a framework from the scientific community. The first step in validating the prototype framework involved five semi-structured interviews with Dutch assessment and multimedia experts to produce a final version of the framework. Second, the pilot MBPA was reconstructed in accordance with this finalized framework, resulting in an improved MBPA and demonstrating that the proposed framework is a useful and applicable tool for the design and development of MBPA in vocational education. 相似文献

Abstract Beginning with Wallace Stevens, the influence of Simone Weil’s philosophy of decreation on American poetry has been substantial, if often underestimated. Focusing on recent volumes by Jorie Graham and Anne Carson, I suggest that this use of Weil’s philosophy presents a new way of understanding a dominant trend towards the metaphysical and difficult in modern American poetry. In various and divergent ways, both poets’ work explicitly points towards a decreated world and explores the ways in which poetry replaces prayer when God is absent. Both in form and content, this work expands upon and illuminates ideas put forth by thinkers such as Blanchot and Nancy, but it is primarily through an understanding of Weil and decreation that such work can best be approached. For Carson and Graham, poetry is the best expression of the imminent void; by placing their work in a definite Weilian context, it is possible to reveal their claims about the nature of truth, God and the material world more fully. 相似文献

Salt crystallization is recognized as a major cause of damage to porous building materials, threatening the sustainable preservation of our valuable built heritage. Unfortunately, the crystallization behavior of the detected salt mixtures is complex and not fully understood. While the deliquescence points of single salts are well documented, this is not the case for salts in a mixture where one is confronted with the presence of different cations and anions. In this paper the salt content of the murals and the limestone tracery of the main entrance porch from the sixteenth century church of St. James in Liège, Belgium is investigated and related to the climatic conditions of its environment. Concerning the salt load, the research consists of hygroscopic moisture content measurements, quantitative ion analyses, and the prediction of phase equilibria using the thermodynamic model ECOS/RUNSALT. This model can predict the salt crystallization sequences of a particular ion mixture. The output is mathematically evaluated with collected temperature and relative humidity data, which enables the calculation of the number of salt crystallization–deliquescence cycles. The results show that even small amounts of salts can cause damage over a long period of time when the environment causes frequent cycles of crystallization–deliquescence over time. It is shown how a mixture of small amounts of (double) salts, including hygroscopic ones, can have a significant effect on the decay of historic building materials in the case of daily changing climatic conditions and periods of extreme drought. As a result, the crystallization of double salts and hygroscopic salts such as calcium nitrate cannot be ignored. The scientific method and the results are described. 相似文献
