The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ2 (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

Anne Jones (of the Froebel Institute College, Roehampton Institute of Higher Education) and David Johnson (Head of the Department of Neuropsychology, Astley Ainslie Hospital, Edinburgh) consider some of the problems experienced by children with head-injury on their return to school. Although education is an integral part of rehabilitation, the organisation of services and the provision of accurate information, training and communication between different agencies were all found to be inadequate. Given the high incidence of head-injury, urgent attention to these problems is essential. 相似文献

This paper builds on Leslie Morton's vision of enabling users through education and training. It describes three different approaches to mediated training for medical students and clinicians provided by peers, juniors (i.e. medical students) and information specialists (i.e. clinical librarians) and considers the benefits to the participants. The training was provided either on a one-to-one basis or within teams in their work environments (e.g. offices, wards, team meetings). The first two projects (peer tutoring and reverse mentoring) suggest that contextualized training, using intermediaries, provides the direct benefit of cost-effective IT skill development and the indirect benefits deriving from the interactions between the trainers and the target groups. The third project, the outreach librarian study, provides evidence of both direct benefits (i.e. time saved, quality of service, skills acquired, financial savings and improved evidence-based medicine implementation) and indirect, long-term benefits relating to more social issues (e.g. perceptions of the library, clinical teams, job satisfaction and patient interactions). The general conclusion to emerge from this review of case studies is that the concept of educational benefits is very broad and that empirical studies need to look at both obvious and less obvious benefits. 相似文献
