The field of educational measurement has evolved considerably since the first doctoral programs were established. In response, programs have typically tacked on courses that address newly developed theories, methods, tools, and techniques. As our review of current programs evidences, this approach produces artificial distinctions among topics and techniques that are in fact a tightly coupled whole. This position paper advocates a redesign of the scope and sequence for doctoral programs focused on the preparation of the next generations of educational measurement specialists; a redesign that reflects the full life‐cycle of instrument development and use. 相似文献

Strategic planning and priority-setting have become inevitable for UK research funding agencies in the 1990's. But it is an activity which is viewed with some suspicion by the scientific community, in which it is an aphorism that discovery cannot be planned. There is considerable interest therefore, in the promise offoresight analysis as an alternative to conventional strategic planning. Most previous experience with foresight has been at a macro level, with a focus on national direction-setting. But what role can foresight have at amicro level; how can it help individual funding agencies develop strategies for specific scientific fields? This paper explores the problem by describing an experiment, supported jointly by three UK funding agencies, to apply foresight techniques in a review of a single field (cardiovascular research). The methodology developed for objective consultation with scientists and users is described, and preliminary results presented. Science-push and demand-pull factors emerged clearly, aa did a desire within the scientific community for a number of infrastructural changes to strengthen the future of the field. The study has shown that systematic surveys of users and researchers are capable of detecting coherent views on a number of issues that are relevant to forward planning in research funding agencies. The paper concludes by summarising the limitations of this approach to strategic planning, and presenting some general lessons that may be useful for consideration in other micro-level foresight exercises. 相似文献

The unforeseen trials of arts-based research may suppress creative and innovative explorations. Photovoice, a visual method of investigation employing participatory photography, presents a host of apprehensions. Yet, photovoice is both a valid and rich methodology that can greatly expand the reach and scope of applied communication research. In this essay, we – three applied communication researchers – discuss the complexities of photovoice, highlighting areas of consideration that interested researchers should contemplate before utilizing this methodology. Briefly exploring three of our research studies and their varying topics (i.e. long-term cancer survivors, domestic violence organizational advocacy, male body culture), we discuss three broad areas of difficulty in photovoice research: analysis, control, and exposure. Despite the unique obstacles that photovoice presents, we argue that it, along with other forms of arts-based research, are profitable and definitely worth the challenge. 相似文献

E-books and audiobooks are becoming increasingly popular in the United States. Unfortunately, the supply of digital titles does not meet the demand. Library patrons must frequently wait for weeks to receive popular e-books. We examined the issue of wait time for e-book and audiobook titles using three public library patron accounts to gather data consisting of the average daily number of wait spots for each title, and days until the title was available. Based on our observations, we propose the Waiting Reduction Rate (WRR) formula to determine the average number of wait spots per title as a metric to help determine a better holds-to-copy ratio for electronic materials and reduce patron wait time. 相似文献
