BACKGROUND: Because of the expense of updating practice guidelines, recent attention has focused on approaches that can reliably assess any updating required. Shekelle et al. (Journal of the American Medical Association 2001, 286, 1461-7) proposed using limited literature searches with expert involvement to reduce resources used in assessing whether a guideline needs updating. OBJECTIVES: This study compared Shekelle's method and the traditional systematic review method regarding comprehensiveness and effort. METHODS: Two research teams translated critical key questions on screening test treatments and outcomes to Medical Subjects Headings (MeSH) and search strategies. They refined Shekelle's method over three iterations, seeking greater efficiency. Using both methods independently, teams assessed the need to update six topics from the 1996 Guide to Clinical Preventive Services (US Preventive Services Task Force). Outcomes included completeness of study identification, importance of missed studies and effort involved. RESULTS: The revised review approach produced fewer citations than the traditional approach and saved time, identifying fewer eligible studies than the traditional approach. None of the studies missed was rated important by the experts consulted. CONCLUSIONS: The revised review approach provides an acceptable method for judging whether a guideline requires updating. Librarians were an integral part of the research process that streamlined the searches.  相似文献

This article propose the Precision Education Initiative, which is the tailoring of education to the specific characteristics of the individual student. Mirroring precision medicine, the author lays out both near‐term and longer term goals that educational research, and importantly educational practice, should follow.  相似文献

Despite extensive research supporting educational acceleration for students with high academic ability, some psychologists, counselors, and educators express concerns about accelerative interventions. Such concerns often hinge on uncertainty about social acceptance, even in inclusive education settings. Research on acceleration has consistently shown benefits for students with high ability; however, there is a lack of research about grade‐based acceleration in inclusive schools. This study engaged two groups of students in group concept mapping processes to examine how they conceptualized beliefs about grade‐based acceleration in inclusive schools. First, 26 students in inclusive classes generated beliefs about grade‐based acceleration. Then they, and a group of 14 students with high ability, structured the data by sorting and rating a synthesized list of the generated beliefs. We analyzed the sorted data using multidimensional scaling and hierarchical cluster analysis. The resultant cluster maps revealed some differences and some similarities in the ways that the two groups of students conceptualized beliefs about educational acceleration. Practical implications are discussed.  相似文献

Despite the rapid growth in the use of computers in organizations, few of the resulting systems have had a significant impact on the way in which management makes decisions. Frameworks are needed which aid in understanding the structure of management information systems, toward providing focus and improving the effectiveness of systems efforts.This paper surveys recent conceptual and empirical work related to development of decision-oriented frameworks for management information systems design, particularly as related to the improving the management of organizations.  相似文献

Part of what has given higher education its remarkable stability in recent years has been its diversity. From the point of view of policy, there are three kinds of diversity in higher education: systemic, programmatic, and structural. Binary higher education systems, representing a form of systemic diversification, have evolved as a response to the massification of higher education. However, because of a number of factors, the perceived ideal remains the traditional university. The non‐university components of binary systems tend increasingly to resemble universities through processes of academic drift. To prevent these processes which in fact negate many of the intentions of planned diversification, social esteem and prestige must be built into all sectors which will then have an interest in preserving their individual identities.  相似文献
