本研究利用建构图设计一套含有六大部分的30道试题。题型包括拼写题、选择题和简答题。共有175名6到14岁儿童参加了此项考试。Rasch分析结果发现题组内局部题目依赖并不严重。信度为0．85。考题的难度和考生能力的配合度相当良好。我们根据建构图来编写考题,因此有一定程度的内容效度。但有9道题的难度稍微与原先预期略有出入。有5道题不大吻合Rasch模式的预期,没有发现在性别上有明显的项目功能差异。考生能力与学习英语的时间有正相关。最后探讨了基于信息通讯技术的远程计算机自适应测验的技术问题。 相似文献

Objective
The research determined the usage and satisfaction levels with one of two point-of-care (PoC) resources among health care providers in a rural state.Methods
In this randomized controlled trial, twenty-eight health care providers in rural areas were stratified by occupation and region, then randomized into either the DynaMed or the AccessMedicine study arm. Study participants were physicians, physician assistants, and nurses. A pre- and post-study survey measured participants'' attitudes toward different information resources and their information-seeking activities. Medical student investigators provided training and technical support for participants. Data analyses consisted of analysis of variance (ANOVA), paired t tests, and Cohen''s d statistic to compare pre- and post-study effects sizes.Results
Participants in both the DynaMed and the AccessMedicine arms of the study reported increased satisfaction with their respective PoC resource, as expected. Participants in both arms also reported that they saved time in finding needed information. At baseline, both arms reported too little information available, which increased to “about right amounts of information” at the completion of the study. DynaMed users reported a Cohen''s d increase of +1.50 compared to AccessMedicine users'' reported use of 0.82. DynaMed users reported d2 satisfaction increases of 9.48 versus AccessMedicine satisfaction increases of 0.59 using a Cohen''s d.Conclusion
Participants in the DynaMed arm of the study used this clinically oriented PoC more heavily than the users of the textbook-based AccessMedicine. In terms of user satisfaction, DynaMed users reported higher levels of satisfaction than the users of AccessMedicine.Keywords and Medical Subject Headings (MeSH) Clinical Decision Support Systems, Computer-Assisted Decision Making, Decision Making, Evidence-Based Library and Information Practice, Evidence-Based Practice, Health Status Disparities, Health Care Disparities, Information Divide, Information-Seeking Behavior, Medically Underserved Area, Nurse Practitioners, Nurses, Physician Assistants, Physicians, Public Health Nurses, Randomized Controlled Trial as Topic, Service Learning, Vulnerable PopulationsHealth care practitioners regularly seek to incorporate valid information into their evidence-based decisions. Electronic information resources now provide easy access to current health information and summarized forms of evidence to support clinical decision making.Access effects on health care
Health care providers who are affiliated with well-funded institutions benefit from access to a variety of high-quality information resources to support their evidence-based practices. Practitioners who are not affiliated with academic health sciences centers rarely have access to these same resources due to prohibitively high licensing costs. Ely et al. report that not having access to easy-to-use, high-quality, current information can negatively affect sound clinical decision making. [1].Patients in Isaac et al.''s study who were admitted to hospitals that had access to an electronic evidence-based resource experienced reduced length of stay and lower risk-adjusted mortality rates for prespecified conditions [2]. That study was validated on a broader scale by a multicenter investigation on the utilization of information resources by practitioners [3].Primary health care practitioners who are not affiliated with academic health sciences centers, particularly those who practice in rural or remote areas, often articulate the need for increased access to health information resources. The authors'' literature search and review of 114 of the most relevant research articles about the information needs and information-seeking behavior of health care practitioners suggested that these professionals most value speed and accuracy. For example, they likely would prefer to use point-of-care (PoC) resources for quickly and accurately answering their clinical questions.Desirability of point of care
PoC resources quickly guide physicians through the diagnosis, treatment, and management of commonly encountered clinical conditions. PoC resources can present compilations of highly authoritative, often evidence-based, information. Physicians can answer more questions and revise clinical decisions more often using these PoC resources [4]. Meanwhile, many health care practitioners still rely on textbooks familiar to them from their professional training programs, despite their potentially dated contents [5–14].Limited access in rural New Mexico
A randomized controlled trial involving public health practitioners across the rural state of New Mexico reported many barriers in accessing valued information resources [15, 16]. In another study, researchers in New Mexico set out to determine and analyze information needs of health care practitioners who were not affiliated with an academic center. Fifty-one interviews of rural physicians, nurses, physician assistants, and nurse practitioners showed both a need and desire for access to information resources [17].Goals and hypothesis
This study sought to determine which rural health care providers found more useful in answering everyday clinical questions: electronic PoC DynaMed, which is more clinically oriented, or electronic PoC AccessMedicine, which consists primarily of a health sciences textbook collection. We hypothesized that free access to the explicitly clinical format of the PoC resource DynaMed would result in more extensive use than a baseline of zero over a six-month period than the electronic PoC textbook collection AccessMedicine. We felt this would be due to greater utility of DynaMed in clinical practice. We also predicted that clinicians using the clinically oriented PoC would express higher levels of satisfaction than those using the textbook-based PoC and that clinicians using these PoC resources would prefer using them over other information resources. 相似文献37.

About 9,000 West German students representing the whole range of academic aptitude were examined at the beginning of their 13th school year. A general scholastic aptitude test was administered, and school marks and information on the pupils’ extracurricular interests and activities recorded. A group of highly gifted students was defined in terms of exceptional performance both in school and on the scholastic aptitude test. The extracurricular activities of this group were compared with those of the representative group. The popular hypothesis that superior cognitive giftedness and outstanding achievement in school go with an ‘impoverishment’ of extracurricular activities was not supported: In most areas a larger percentage of the highly gifted than of the reference group were actively involved. Furthermore, the range of individual activities was somewhat broader among the top students than among the representative group. 相似文献
