As literacy grows in importance, policymakers’ demands for programme quality grow, too. Evidence on the effectiveness of adult and family literacy programmes is limited at best: research gaps abound, and programme evaluations are more often than not based on flawed theories of programme impact. In the absence of robust evidence on the full range of short- and long-term programme impacts, it is difficult to accurately measure intervention effectiveness. Too frequently, researchers and policymakers focus only on short-term, easily measured outcomes, creating a ‘tyranny of effect size’ that may systematically underestimate impact while simultaneously distorting practice. However, the answer does not lie in turning away from quantitative research. Doing so will consign adult and family literacy to the margins of public policy, when they should be in the mainstream. Longitudinal research from Turkey and the US suggests a need for revised, more subtle theories of how adult literacy and family literacy programmes work, and the diverse ways they benefit participants. By working together more closely and intelligently, researchers, policymakers and practitioners can develop evaluation strategies that more accurately measure programme effects. The key is combining methodological rigour with fully fleshed out theories of literacy development and programme impact.  相似文献

This paper discusses the challenges of finding evidence needed to implement Evidence-Based Librarianship (EBL). Focusing first on database coverage for three health sciences librarianship journals, the article examines the information contents of different databases. Strategies are needed to search for relevant evidence in the library literature via these databases, and the problems associated with searching the grey literature of librarianship. Database coverage, plausible search strategies, and the grey literature of library science all pose challenges to finding the needed research evidence for practicing EBL. Health sciences librarians need to ensure that systems are designed that can track and provide access to needed research evidence to support Evidence-Based Librarianship (EBL).  相似文献

This case study describes strategies developed for medical students to conduct Specific (as opposed to Sensitive) searches in PubMed so they can quickly locate several relevant references to articles on the population and social aspects of medicine. The Specific search strategy protocol for population and social aspects of medicine involves use of the MeSH Database, certain features of the Detailed Display in the MeSH Database, and applying Limits. By teaching the Specific form of search strategy, busy users can learn a handful of basic techniques that should yield a useful proportion of references, thereby ensuring these users' frequent success.  相似文献

Objective:

The research tested the accuracy of the VIVO Harvester software in identifying publications authored by faculty members affiliated with a National Institutes of Health Clinical and Translational Sciences Award (CTSA) site.

Methods:

Health sciences librarians created “gold standard” lists of references for the years 2001 to 2011 from PubMed for twenty-five randomly selected investigators from one CTSA site. These gold standard lists were compared to the same twenty-five investigators'' reference lists produced by VIVO Harvester. The authors subjected the discrepancies between the lists to sensitivity and specificity analyses.

Results:

The VIVO Harvester correctly identified only about 65% of the total eligible PubMed references for the years 2001–2011 for the CTSA-affiliated investigators. The identified references produced by VIVO Harvester were precise yet incomplete. The sensitivity rate was 0.65, and the specificity rate was 1.00.

Conclusion:

While the references produced by VIVO Harvester could be confirmed in PubMed, the VIVO Harvester retrieved only two-thirds of the required references from PubMed. National Institutes of Health CTSA sites will need to supplement VIVO Harvester–produced references with the expert searching skills of health sciences librarians.

Implications:

Health sciences librarians with searching skills need to alert their CTSA sites about these deficiencies and offer their skills to advance their sites'' missions.  相似文献

Every major health profession now provides competency statements for preparing new members for their respective professions. These competency statements normally include expectations for training health professions students in library/informatics skills. For purposes of this article, searches were conducted using various sources to produce a comprehensive 32-page Compendium that inventories library/informatics-related competency statements. This compendium should aid readers in integrating their library/informatics skills training into various health professions education curricula.  相似文献
