Primary teachers, whether or not they have a specialized background in science, hold the key to understanding how science is presently working in primary schools. This paper examines their confidence and identity as science teachers in tandem with their views on the English National Curriculum and the warrants they give for those views. Data for this study were collected by in‐depth interviews of a small sample of primary teachers, setting their views in the context of their science‐related life histories. These are presented in three ways—by biographical sketches illuminating their self‐image as science teachers; by analysis of their views on the curriculum; and by analysis of the types of knowledge they used as warrants for their views. Analysis showed that their professional self‐image and their ‘science autobiographies’ were mutually validating. Where science teaching had become embedded into their perception of themselves as teachers, their critiques of the science curriculum and their desire for autonomy in its teaching could be shown to be consistent with their values © 2000 John Wiley & Sons, Inc.

Training researchers and practitioners have typically focused their attention on one type of transfer, the transfer of tasks that require trainees to learn and apply a prescribed standard procedure. Further, researchers and practitioners have examined this type of transfer in situations where supervisors hold trainees accountable for applying the trained knowledge and skill, Performance professionals have developed theoretical frameworks, training principles, and training guidelines to improve transfer based on this conception of transfer. In contrast, this paper presents a multidimensional perspective to training transfer. One dimension concerns task adaptability-a continuum from relatively closed tasks, where task steps are highly prescribed, to relatively open tasks, where the task steps can be adapted to varying circumstances of the job. The other dimension concerns worker autonomy-a continuum from heavily supervised to highly independent work. Based on this expanded perspective of transfer, for each combination of variable, we offer principles for effective transfer as well as specific problems which must be solved to achieve the best results. We also provide suggestions for evaluating training success and derive research propositions that deserve attention.  相似文献

Electronic learning delivery systems discussed include satellite networks, teleconferencing, Internet/Intranet networks, desktop multimedia, electronic performance support systems (EPSS), transportable audio/video (i.e., systems relying primarily on physically transportable audio-and videotaped materials), and the electronically enhanced classroom. Selecting one of these systems can be a daunting task when all relevant issues are considered. The selection model described in this article narrows the choices to the system most likely to be instructionally, economically, and technologically appropriate. After establishing working definitions, the model suggests four stages of user activity: 1) Assessing several important overall factors, including outcomes and conditions of learning, economics, synchronicity and location, and organizational culture; 2) Rating the importance of several learning system attributes to the training project; 3) Selecting the system that most ideally supports the attributes which the user has rated as important; and finally, 4) Validating the selection by reviewing the final choice in light of first stage overall factors.  相似文献

General dissatisfaction with commercial norm-referenced tests and global ability measures and the need for more specific achievement measures due to changes in special education have led to an increased interest in the curriculum-based assessment of reading. We argue that a curriculum-based assessment (CBA) of reading provides relevant information for instructional interventions only if the content of the curriculum and instruction are grounded in the cognitive skills underlying the domain of reading. If CBA is based on valid cognitive constructs, it may assist greatly in the identification of younger readers at risk for reading problems, older students with reading problems, and provide the most sensitive measure of continuous progress. We discuss the implications of our review for the training of school psychologists and for consultation. © 1998 John Wiley & Sons, Inc.  相似文献

Focusing strategies are known to play a significant role in motor performance, with individuals who use an internal focus on body movement typically showing poorer outcomes than those who focus on features of the external environment. Focus of attention and switching of one's focus are examined in the context of two different complex motor skills along with a factor not previously examined systematically, individual preference. In both experiments, participants were introduced to focusing strategies that might be employed when attempting a sensorimotor task. Explanations of both strategies were given to participants. Specifically, for an internal focus, participants were instructed to concentrate on their body movements, while for an external focus, they were instructed to focus on aspects in the environment. They were then asked which strategy they preferred. Participants then continued either with their preferred focus or were instructed to switch to their non-preferred focus. The advantage that the external focus typically enjoys turns out not to be a simple one and interacts with individual preference and with the "forced-opposite" manipulation. Our results support the growing consensus that encouraging individuals to adopt an internal focusing strategy is counterproductive in complex sensorimotor tasks. They also suggest that individual preferences play a role.  相似文献

The purpose of this study was to examine the following: (a) the relationships among the latent constructs of fundamental motor skills (FMS), health-related physical fitness (HRF), and observed body fatness in South Korean adolescents with mental retardation (MR); (b) the indirect effect of fundamental motor skills on body fatness when mediated by health-related fitness; and (c) whether the degree of MR and gender affects these relationships. Students ages 13 to 18 years (287 boys and 134 girls) were recruited for the study. Separate structural equation models were estimated based on gender and the level of disability: mild or moderate MR. Group differences in the model structure were not found, so the data were combined and a single model estimated. The results showed that FMS significantly contributed to HRF (standardized effects beta = .53), p < .01 and indirectly contributed to decreased body fatness mediated by HRF (-.27), p < .01. HRF directly contributed to decreased fatness (-.50), p < .01. The results from this study support the importance of both increased FMS and increased HRF in relation to decreased body fatness.  相似文献
