This article describes a set of computerized tools that support the design and evaluation of competency-based training programs. The training of complex skills such as air traffic control and process control requires a competency-based approach that focuses on the integration and coordination of constituent skills and transfer of learning. At the heart of the training are authentic whole-task practice situations. The instructional design tools are based on van Merriënboer's 4C/ID* methodology (1997). The article describes a training design tool (Core) that supports the analysis and design for competency-based training programs and an evaluation tool (Eval) that supports the subsequent revision of this training design. 相似文献

The aim of this study was to establish whether asymmetry of the strength of the leg and trunk musculature is more prominent in rowers than in controls. Nineteen oarsmen and 20 male controls matched for age, height and body mass performed a series of isokinetic and isometric strength tests on an isokinetic dynamometer. These strength tests focused on the trunk and leg muscles. Comparisons of strength were made between and within groups for right and left symmetry patterns, hamstring: quadriceps ratios, and trunk flexor and extensor ratios. The results revealed no left and right asymmetries in either the knee extensor or flexor strength parameters (including both isometric and isokinetic measures). Knee extensor strength was significantly greater in the rowing population, but knee flexor strength was similar between the two groups. No difference was seen between the groups for the hamstring: quadriceps strength ratio. In the rowing population, stroke side had no influence on leg strength. No differences were observed in the isometric strength of the trunk flexors and extensors between groups, although EMG activity was significantly higher in the rowing population. Patterns of asymmetry of muscle activity were observed between the left and right erector spinae muscles during extension, which was significantly related to rowing side (P < 0.01). These observations could be related to the high incidence of low back pain in oarsmen. 相似文献

Competence to work in schools is an important dimension of professional competence, although it is often a neglected dimension of teacher development. This article reports a qualitative study that examined student teachers’ learning experiences in initial teacher education (ITE) in relation to competence to work in schools. In-depth interviews were conducted with 12 student teachers on an undergraduate ITE programme in Hong Kong. The findings of the study show that competence to work in schools is characterised by student teachers’ deep contextualised learning. In addition, it offers a deeper understanding of this competence in the ITE context by identifying its three facets, namely understanding of the micro-political realities of schools, social capital building and social strategies. The study provides insights for ITE and schools to support student teachers’ development of their competence to work in schools, including the design of ITE curricula, ITE processes and co-curricular activities in undergraduate studies. Moreover, it suggests the importance of developing schools as growth-fostering and positive micro-political sites for ITE fieldwork and teacher induction. 相似文献

AbstractThe aim of this study was to develop a performance test set-up for America's Cup grinders. The test set-up had to mimic the on-boat grinding activity and be capable of collecting data for analysis and evaluation of grinding performance. This study included a literature-based analysis of grinding demands and a test protocol developed to accommodate the necessary physiological loads. This study resulted in a test protocol consisting of 10 intervals of 20 revolutions each interspersed with active resting periods of 50 s. The 20 revolutions are a combination of both forward and backward grinding and an exponentially rising resistance. A custom-made grinding ergometer was developed with computer-controlled resistance and capable of collecting data during the test. The data collected can be used to find measures of grinding performance such as peak power, time to complete and the decline in repeated grinding performance. 相似文献

Impact of National Aquarium in Baltimore on Visitors' Conservation Attitudes,Behavior, and Knowledge
This study at the National Aquarium in Baltimore (NAIB) was conducted to assess four key aspects of the visitor experience: (1) incoming conservation knowledge, attitudes, and behavior of NAIB visitors; (2) patterns of use and interaction with exhibition components throughout the NAIB; (3) exiting conservation knowledge, attitudes, and behaviors of visitors; and (4) over time, how the NAIB experience altered or affected individuals' conservation knowledge, attitudes, and behaviors. Three hundred six visitors participated in the study, which was conducted from March through July, 1999. The study utilized four data‐collection techniques: (1) face‐to‐face interviews, (2) Personal Meaning Mapping (PMM), (3) tracking, and (4) follow‐up telephone interviews. Participants were a self‐selected population and were generally more knowledgeable about, more concerned about, and more involved in conservation‐related issues than the general public. However, they were far from conservationists. Visitors in this study clearly absorbed the fundamental conservation message at the NAIB. In fact, the NAIB visit appeared to focus visitors' conservation‐related thoughts, while also broadening their understanding of conservation. Changes in visitors' conservation knowledge, understanding, and interests by and large persisted over six to eight weeks after visiting NAIB. The NAIB experience also connected to visitors' lives in a variety of ways following their visit. However, these personal experiences rarely resulted in new conservation actions. In fact, their enthusiasm and emotional commitment to conservation (inspired during the NAIB visit) generally fell back to original levels, presumably in the absence of reinforcing experiences. The findings of this study are guiding subsequent investigations at the NAIB. More generally, the results suggest strategies to enhance current understanding of the impact free‐choice learning institutions have on their visiting public. 相似文献

Two studies examine reactions to permitted (offered and permission granted), volunteered (given without offer or assent), and imposed advice (offered and given even though declined). In Study 1, participants’ ratings of advice quality and implementation intention were higher for volunteered and permitted than imposed advice. Only for a task that was highly personal did recipients have a significantly higher intention to use permitted than volunteered advice. Study 2 replicated results from Study 1 with a nonstudent sample. In addition, Study 2 found stronger differences between volunteered and permitted advice, with permitted advice rated more positively. Study 2 also examined the effect of using you pronouns, which have been linked to confrontation and criticism, when giving advice, but found no consistent effects on advice outcomes. 相似文献
