This article presents a rich context of information for interpreting Stanford Achievement Test scores and for describing the achievement of deaf and hard-of-hearing students. The publisher's national norming of the Stanford Achievement Test provides a context of actual performance of hearing students. The publisher's Performance Standards provide a context of expectations for hearing students as determined by a panel of experts. The Gallaudet Research Institute's norming of the test on a national sample of deaf and hard-of-hearing students provides a context of test performance by this special population. A smaller subsample of the deaf and hard-of-hearing students who take the same test levels as hearing students provides an additional reference group with respect to the Performance Standards. Information from these sources is brought together into two graphical contexts to address these questions: Can the normative data from the publisher's national standardization of the test with hearing students, and the normative data from the GRI's national norming of the test with deaf and hard-of-hearing students provide a useful context for the interpretation of individual test scores? Can they provide a useful way to examine achievement of groups of students? Can the new Performance Standards defined by the test publisher offer a useful context for test score interpretation for high-achieving deaf and hard-of-hearing students? 相似文献

The issue that this article introduces grew out of an event, the UNESCO Mobile Learning Week, but also out of a wider and growing movement of people and organisations exploiting mobile technologies, as they pursue varied educational missions. The UNESCO Mobile Learning Week represented by contributions here was a focus for contributions from across the field. This article provides a wider discussion of these contributions, first by looking at the achievements of UNESCO and then by considering these achievements more critically. In particular, it highlights several sets of inherent challenges facing UNESCO and other organisations engaging in mobile learning: those around evidence, evaluation, and sustainability; the problematic tension between large-scale interventions, based on scale and content delivered by national governments, and the language and culture of marginal or indigenous people; the absence of appropriate ethics procedures to manage educational interventions delivered by a powerful and ubiquitous technology; and the absence of learners in the forums that address all these various issues. 相似文献

Many instructors in science, technology, engineering, and mathematics fields are striving to create active learning environments in their classrooms and in doing so are frequently moving the lecture portion of their course into online video format. In this classroom-based study, we used a two group randomized experimental design to examine the efficacy of an instructional video that incorporates a human hand demonstrating and modeling how to solve frictional inclined plane problems compared to an identical video that did not include the human hand. The results show that the learners who viewed the video without the human hand present performed significantly better on a learning test and experienced a significantly better training efficiency than the learners who viewed the video with the human hand present. Meanwhile, those who learned with the human hand present in the instructional video rated the instructor as being more humanlike and engaging. The results have implications for both theory and practice. Implications for those designing instructional videos are discussed, as well as the limitations of the current study. 相似文献

In a comprehensive empirical investigation (N = 71,405) we analyzed the development of legal expertise in a critical 1-year period of academic legal training in which advanced law students start practicing to solve complex cases. We were particularly interested in the functional form of the learning curve and inter-individual differences in learning. Performance increases monotonically with the number of practice exams following a slightly concave learning curve without any considerable kinks. Considering the performance development over time, however, the curve is not monotonic and shows intermediate drops in performance. We provide evidence which suggests that these drops are due to cyclic drops in motivation. There are about equally sized marginal effects of practicing law exams in general and practicing exams in the specific area of law. However, students with high (vs. low) initial performance profit more from practicing exams within a specific area of law whereas students with low initial performance profit more from practicing exams in general. The concave increase in performance with the number of practicing exams is mainly driven by individuals with low initial performance. Those with high initial performance mainly display a linear learning trend. We discuss the practical implications of these findings for academic legal training. 相似文献

This paper addresses ways that mobile technologies can be used in teacher development, and focuses on mobile technologies. In particular, it addresses issues of context. It outlines and explores accepted practice and illustrates how mobility invites change and reappraisal of the teacher education process. It places this against a backdrop of current global challenges and questions the validity of existing educational systems in the face of those challenges. It then places mobile technology in the role of digital learning tool rather than content delivery system and explores how teacher education needs to adapt to the context of learning that is presented by increased mobility. Finally, it explores the relationship between knowing and doing in teacher education, acknowledging tension in two areas: first, between the standardisation of practice and the creation of user-defined and user-owned knowledge creation based on interaction with distinct contexts and second, between the social practice of learning through mobility and the ‘otherness’ of formal education. 相似文献

Electronic Performance Monitoring (EPM) is a common technique used to record employee performance. EPM may include counting computer keystrokes, monitoring employees' phone calls or internet activity, or documenting time spent on work activities. Despite EPM's prevalence, no studies have examined how this management tool affects older workers–a steadily increasing labor pool. In the current interdisciplinary study, 85 older (M=46.9 years) and 77 younger participants (M=22.1 years) were randomly assigned to perform a simple or difficult computer data‐entry task under two conditions: monitored or not monitored. ANCOVA results indicated that EPM decreased performance and induced higher stress levels compared to non‐monitored conditions when computer experience levels were controlled. Additionally, older adults showed a trend of being more impacted by EPM when compared with younger adults. Results are discussed in terms of how EPM might be most effectively used by organizations while minimizing employee stress levels. 相似文献
