The relationship between ageing and skills is of growing policy significance due to population ageing, the changing nature of work and the importance of literacy for social and economic well‐being. This article examines the relationship between age and literacy skills in a sample of OECD countries using three internationally comparable surveys. By pooling the survey data across time we can separate birth cohort and ageing effects. In doing so, we find that literacy skills decline with age and that, in most of our sample countries, successive birth cohorts tend to have poorer literacy outcomes. Therefore, once we control for cohort effects, the rate at which literacy proficiency falls with age is much more pronounced than that which is apparent, based on the cross‐sectional relationship between age and literacy skills at a point in time. Further, in studying the literacy‐age relationship across the skill distribution in Canada we find a more pronounced decline in literacy skills with age at lower percentiles, which suggests that higher initial literacy moderates the influence of cognitive ageing. 相似文献

Abstract Rural communities need rural teachers who can “ground” traditional school subjects in local realities and dilemmas and at the same time fashion instructional approaches consonant with larger intellectual, ethical, and social purposes. Such teachers are assets rather than burdens to their communities. Only such teachers can cultivate an ethic of responsibility for the health and vitality of the communities of which they and their students are critical components. This essay examines the role of the university in professionalizing rural teachers. It contends that narrowly utilitarian ends prevail in teacher education programs, and that, in the absence of a substantive definition of educations public purpose, this instrumentalism creates teachers who are ill‐prepared to contribute in meaningful ways to the intellectual life of the communities in which they work. Teacher preparation programs should abandon the instrumental focus. Programs that prepare rural teachers, in fact, confront unique challenges and opportunities to include three themes at their centers: Sustainability, Social Justice, and Democracy. 相似文献

Study One examined the influence of initial use of hesitations and hedges on evaluations of witnesses and their persuasiveness in a budget hearing context. Results indicate that the negative attributions generated by the use of powerless language cannot be overcome by subsequent use of powerful talk. Study Two examined the relationship between the frequency of powerless language use and impression formation. For award/character and dynamism a perceptual threshold appeared to operate. The results of both studies suggest that auditors are very sensitive to the influence of powerless talk in formal settings. 相似文献

Item parameter drift (IPD) occurs when item parameter values change from their original value over time. IPD may pose a serious threat to the fairness and validity of test score interpretations, especially when the goal of the assessment is to measure growth or improvement. In this study, we examined the effect of multidirectional IPD (i.e., some items become harder while other items become easier) on the linking procedure and rescaled proficiency estimates. The impact of different combinations of linking items with various multidirectional IPD on the test equating procedure was investigated for three scaling methods (mean-mean, mean-sigma, and TCC method) via a series of simulation studies. It was observed that multidirectional IPD had a substantive effect on examinees' scores and achievement level classifications under some of the studied conditions. Choice of linking method had a direct effect on the results, as did the pattern of IPD. 相似文献

Troubleshooting skills are integral for the Information Technology professional. In order to address faculty concerns that
students were not effectively learning required troubleshooting skills, a standardized troubleshooting methodology (the DECSAR
Method) was created and integrated into the standard curriculum of a college information technology program. Components of
troubleshooting were measured using a pre-/post-testing approach with the Social Problem Solving Inventory—Revised. Testing
indicated improvement in several areas of troubleshooting reinforced by DECSAR. The context in which the troubleshooting methodology
was applied was associated with post-test change.

As assistive technology applications are increasingly implemented in early childhood settings for children who are at risk
or who have disabilities, it is critical that teachers utilize observational approaches to determine whether targeted assistive
technology-supported interventions make a difference in children’s learning. One structured strategy that employs observations
and which has powerful child progress monitoring implications is the concurrent time series probe approach. Requiring multiple
performance measures of a child engaged in a targeted task over time—both with and without a specific assistive technology
device—the concurrent time series probe approach can be used to evaluate the effectiveness of assistive technology tools in
supporting skill acquisition in the classroom. This approach is described in the context of a case study, with accompanying
explanations of how to interpret data and make decisions regarding the effectiveness of the technology. 相似文献
