The instrument Samples of Teaching Performance (STP) was developed to assess student teachers' capacity to plan, deliver and evaluate a unit of instruction. The current study reports consequential validity data collected from supervisors (n?=?20) and student teachers (n?=?62) from three elementary and five secondary teacher preparation programs in Chile that participated in the field-testing of the STP. Student teachers described how this assessment had honed their sense of professionalism and promoted learning of the skills assessed. Supervisors reported enlarging the topics discussed with student teachers and making some changes to the supervisory process. These findings are complemented by an analysis of the STP scores obtained by 24 student teachers, which showed better development of instructional skills when compared to pedagogical reasoning and reflection. These results raise questions about the structure of student teaching to support the implementation of standards-based assessments that entail tasks at different levels of cognitive complexity.  相似文献

The topic of emotion regulation and its relationship with teacher effectiveness is beginning to garner attention by researchers. This study examined the relationship between emotion‐regulation ability (ERA), as assessed by the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT), and both job satisfaction and burnout among secondary‐school teachers (N = 123). It also examined the mediating effects of affect and principal support on these outcomes. ERA was associated positively with positive affect, principal support, job satisfaction, and one component of burnout, personal accomplishment. Two path models demonstrated that both positive affect and principal support mediated independently the associations between ERA and both personal accomplishment and job satisfaction. © 2010 Wiley Periodicals, Inc.  相似文献

The aim of this two‐year longitudinal study was to investigate the role and impact of prior mathematics performance, cognitive appraisals and mathematics‐specific, affective anxiety in determining later mathematics achievement and future career orientation among Finnish adolescents. The basic ideas of the control‐value theory, assumed to be culturally universal, and previous controversial results regarding the relationship between mathematics anxiety and mathematics achievement were tested in the Finnish cultural context with a longitudinal design. The key premise of the control‐value theory is that control and value appraisals are significant determinants of both activity and outcome achievement emotions. Our results suggest that mathematics anxiety, a prospective outcome emotion, is determined by outcome expectancies (success or failure) and outcome value (the importance of performing well). They also suggest that anxiety as a negative affective emotion is a problem not only for those who perform poorly but probably also for certain pupils across all achievement levels. Compared with the performance level and with the boys, the girls exhibited inaccurately low outcome expectancies in mathematics. These low expectancies connected to the negative value of failure are a potential cause for their higher anxiety level. The educational implications of the findings are discussed.  相似文献

Service-learning has been put forth as one of the proposed solutions to increasing social capital. However, service-learning research has not significantly addressed the impact of service learning on social capital. Unlike most previous studies, this research used quantitative analysis to measure the effect of university service-learning programs on social capital by examining the question: What impact do service-learning programs have on social capital post-graduation? This study showed that service learning addresses the civic engagement problem by providing evidence suggesting that service learning predicts social capital post-graduation.  相似文献

There have been recent applications of genetic algorithms to information retrieval, mostly with respect to relevance feedback. Nevertheless, they are yet to be evaluated in a way that allows them to be compared with each other and with other relevance feedback techniques. We here implement the different genetic algorithms that have been applied in the literature together with some of our own variations, and evaluate them using the residual collection method described by Salton in 1990 for the evaluation of relevance feedback techniques. We compare the results with those of the Ide dec-hi method, which is one of the traditional methods that yields the best results.  相似文献

We examined the measurement properties offall-related psychological instruments with a sample of 133 older adults (M age = 74.4 years, SD = 9.4). Measures included the Comprehensive Falls Risk Screening Instrument, Falls-efficacy Scale-International (FES-I), Activities-specific Balance Confidence (ABC), modified Survey ofActivities and Fear ofFalling in the Elderly (mSAFFE), Consequences of Falling (CoF), Physical Activity Scale for the Elderly (PASE), and 36-Item Short-Form Health Survey (SF-36). The FES-I, ABC, mSAFFE, and CoF were significantly correlated with each othe, with SF-36, and with mobility. The ABC and mSAFFE were significantly correlated with PASE. The ABC differentiated between fallers and nonfallers and predicted total falls risk. Findings can assist with the selection of psychological instruments in a falls risk screening context.  相似文献

The process of writing for publication is a challenging one. It moves us from the spoken and written word into a realm that requires us to provide supporting evidence to develop an argument in a logical and progressive way. In English language journals, as elsewhere, the quality of the written word is a determining factor in the likelihood of a paper being accepted for publication. By reading past issues of a targeted journal, drawing on the expertise of colleagues and responding positively to feedback, it is possible to significantly enhance your prospects of publication.  相似文献

Background: In the recent times of recession and budget cuts, it is more important than ever for library and information services to deliver cost‐effective services. Objectives: This rapid review aims to examine the evidence for the most cost‐effective ways of delivering enquiry services. Methods: A literature search was conducted on LISA (Library and Information Sciences Abstracts) and MEDLINE. Searches were limited to 2007 onwards. Results: Eight studies met the inclusion criteria. The studies covered hospital and academic libraries in the USA and Canada. Services analysed were ‘point‐of‐care’ librarian consultations, staffing models for reference desks and virtual/digital reference services. Conclusions: Transferable lessons, relevant to health library and information services generally, can be drawn from this rapid review. These suggest that ‘point‐of‐care’ librarians for primary care practitioners are a cost‐effective way of answering questions. Reference desks can be cost‐effectively staffed by student employees or general reference staff, although librarian referral must be provided for more complex and subject‐specific enquiries. However, it is not possible to draw any conclusions on virtual/digital reference services because of the limited literature available. Further case analysis studies measuring specific services, particularly enquiry services within a health library and information context, are required.  相似文献

Background: Considerable barriers still prevent paediatricians from successfully using information retrieval technology. Objectives: To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real‐life clinical scenarios. Methods: In a controlled trial at a paediatric teaching hospital, nine residents and interns were randomly allocated to an assisted search group and nine to a non‐assisted (control) group. Each participant searched Pub Med and other online sources, performing pre‐determined tasks including the formulation of a clinical question, retrieval and selection of bibliographic records. In the assisted group, participants were supported by a librarian with ≥5 years of experience. The primary outcome was the success of search sessions, scored against a specific assessment tool. Results: The median score of the assisted group was 73.6 points interquartile range (IQR = 13.4) vs. 50.4 (IQR = 17.1) of the control group. The difference between median values in the results was 23.2 points (95% CI 4.8–33.2), in favour of the assisted group (P‐value, Mann–Whitney U test: 0.013). Conclusions: The study has found quantitative evidence of a significant difference in search performance between paediatric residents or interns assisted by a librarian and those searching the literature alone.  相似文献
