Calibration of an item bank for computer adaptive testing requires substantial resources. In this study, we investigated whether the efficiency of calibration under the Rasch model could be enhanced by improving the match between item difficulty and student ability. We introduced targeted multistage calibration designs, a design type that considers ability‐related background variables and performance for assigning students to suitable items. Furthermore, we investigated whether uncertainty about item difficulty could impair the assembling of efficient designs. The results indicated that targeted multistage calibration designs were more efficient than ordinary targeted designs under optimal conditions. Limited knowledge about item difficulty reduced the efficiency of one of the two investigated targeted multistage calibration designs, whereas targeted designs were more robust. 相似文献

ABSTRACTIn this study of microteaching in a secondary English methods course, we intentionally stray from normative assessment practice, instead asking pre-service teachers to provide feedback on their peers’ microteaching using assessment practices designed to orient them figuratively. The term ‘figurative’ refers to ‘figurative language’: the bringing together of multiple, seemingly unrelated things, through associative configurations, and placing them side-by-side in order to reorient thought towards new or unexpected meanings. This study reframes assessment, not as a means of collecting data on what students have learned from a given lesson in order to evaluate and augment learning, but instead figuratively, as providing opportunities to expand and imagine ways of meaning-making through and with assessment. We examine in detail four modes of figurative assessment practices through which we sought to surprise and disorient students, producing new and different kinds of responses to microteaching that went beyond normative feedback practices. 相似文献

This contribution reports on an investigation into the importance of supporting first language for the command of first and second language skills using a quasi-experimental longitudinal study of migrant children in kindergarten. For two years the development of both first and second language skills was coordinated through the treatment of the same topics and stories during lessons. Furthermore, parents were asked to read their children a story or play an audio book in the first language three times a week. This extensive intervention neither had statistically significant effects on the development of language competency in the first nor the second language, German. The transfer effects between first and second language expected by the interdependency hypothesis of Cummins were only in evidence to a very limited extent. 相似文献

During the past two decades, relationships between artists and museums have changed in subtle, but significant, ways. Artists have become more fully integrated into the day-to-day workings of the art museum, whether as employees, guest curators, or even as members of decision-making boards. A new awareness of museum ethics in the 1980s has led to questioning of some common practices, and issues such as censorship have come to the fore. What has emerged is the growing realization on the part of both museums and artists that their fates are inextricably linked. 相似文献

Twitter has become a global, social media platform that is reshaping the way journalists communicate, gather information, and disseminate news. This study builds on the relatively young field of research by using diffusion of innovation theory to gauge what factors influence the spread and adoption of Twitter. Case-study and in-depth interview methods were used in collecting data from 50 journalists at 4 metropolitan newspapers. Results show that the adoption and implementation of Twitter relies on peer pressure and coaching to get reluctant journalists to try Twitter. Adoption is then immediate because journalists see how Twitter is a gateway to new sources of information and story tips. Ultimately, journalists embrace Twitter because it provides instant gratification from followers, allowing them to share stories with a broader, global audience. 相似文献
