As the need for instructing a globalized workforce increases, instructional designers must embrace the constraints and the opportunities these projects provide in order to move the field of cross-cultural instructional design (ID) forward. Cross-cultural projects offer multiple avenues for growth in ID practice, overcoming cultural barriers, and a venue to apply and test contemporary models, methodologies, and theories in ID. This design-based research case study employed a rapid prototyping methodology and the constructivist ID model, Layers of Negotiation, to collect critical cultural information for the design of this cross-cultural instruction. Instructional strategies deemed effective for instructing an unskilled workforce in Dubai, United Arab Emirates, included job aids, situated learning and apprenticeship principles consisting of modeling, coaching and scaffolding. Use of the constructivist ID model and instructional solution for a cross-cultural workforce for The Dubai Mall are presented. Evaluation results indicate the success of the instructional strategies varied dependent upon worker culture, and the sequential nature of the instructional strategies.  相似文献

Retrieval practice has been shown to produce powerful learning gains in laboratory experiments but has seldom been explored in classrooms as a means of enhancing students’ learning of their course-relevant material. Furthermore, research is lacking concerning the role of individual differences in learning from retrieval. The current study explored the effects of retrieval in a large undergraduate introductory biology course as a function of individual differences in student achievement. Students completed in-class exercises that required them to retrieve course information (e.g., recalling definitions for terms and labeling diagrams) followed by feedback or to simply copy the information without retrieving it. A later quiz over the information showed that high-performing students benefited more from retrieving than copying, whereas middle- and low-performing students benefited more from copying than retrieving. When asked to predict their quiz scores following the in-class exercises, high-performers demonstrated better overall metacognitive calibration compared to middle- or low-performers. These results highlight the importance of individual differences in learning from retrieval and encourage future research using course-relevant material to consider the role of student achievement in classroom-based interventions.  相似文献

The scientific approach to the restoration and monitoring of mural paintings, at S. Girolamo Chapel – SS. Annunziata Church in Florence, is reported as a fruitful example of the synergic collaboration between restorers and scientists in the planning and development of conservative interventions. Before restoration, the painting technique and the state of preservation of the pictorial cycle have been investigated firstly by close examination of the painted surfaces and then by optical and/or SEM-EDS microscopy and μFT-IR spectroscopy on appropriately selected samples. In particular, the original constituent materials and those belonging to subsequent restorations were characterized together with those originating from decay processes. In this mural painting cycle, a peculiar “fresco” technique has been used although an auxiliary binder for pigment distemper has been also employed. The use of this technique, sometimes in an improper way together with uncorrected restoration interventions, are the main responsible of the unsatisfactory state of conservation of many painted areas. Preliminary conservation trials and scientific studies were carried out to design the most convenient restoration intervention and to verify the correctness and non-invasive of the necessary operations. Special attention was devoted to cleaning procedures, continuously monitored by a physico-chemical methodology, mainly based on microinvasive, microscopic and spectroscopic investigations, to evaluate the efficiency, advantages and drawbacks of the proposed cleaning procedures and define the most appropriate ones. Finally, specific decay markers have been recognized, by a comparison of the results obtained from the detached samples with those deriving from artificially aged models, to be used for a correct future monitoring and maintenance of the wall paintings.  相似文献

Microsaccades are important fixation eye movements for visual scene perception. Compared to novices, athletes make fewer fixations of longer duration toward limited interest areas crucial for action prediction. Thus, our aim was to study the microsaccade features during those fixations. Gaze behaviour of expert and novice table tennis players was recorder during a task in which subjects were instructed to predict the direction of the ball after the opponent’s throw. Three interest areas from the opponent’s body and one from the ball trajectory were identified. We analysed correctness of predictions, fixations, microsaccades and saccades to estimate the relationship between eye movements toward interest areas and success in the task. Compared to novices, experts fixated more on hand-racket during forehand and on trunk during backhand drive technique. Longer fixations on hand-racket and trunk were associated with higher microsaccade rate with a narrower directional distribution of them. It probably means that athletes focused their gaze on these small areas, suggesting enhanced attention mainly to them, and fewer consideration for the surrounding regions. We can assume that microsaccade rate and average direction could be related to the salience of interest areas during performance.  相似文献

The purpose of this study was to examine and describe differences between doctoral and nondoctoral practicing school psychologists. Participants selected for the study were school psychologists who were full-time practitioners in a school setting. The sample was randomly selected from the 1992 National Association of School Psychologists Membership Database. Four hundred forty persons were selected to serve as a sample of the NASP membership, and 359 responded to the survey. Of those that responded, 232 were full-time practitioners employed in the schools and formed the sample used in the data analysis. Overall, doctoral and nondoctoral school psychologists were very much alike in terms of age, gender, and years of experience. Doctoral level school psychologists were more likely to be employed in urban areas. Both groups spend a similar amount of time participating in seven different job activities. Doctoral and nondoctoral level practitioners working in schools maintain high levels of job satisfaction and the majority intend to remain in their current position and the profession for the next five years. Higher salaries and an increased likelihood of having a private practice outside of school are the major differences between doctoral and nondoctoral school psychologists practicing in the schools. Future evolution of the role of school psychologists may allow for the increased use of the advanced skills obtained by doctoral level school psychologists. © 1998 John Wiley & Sons, Inc.  相似文献

In this paper I contend that, although codes of ethics are very good things and could potentially improve performance by acting as a normalising agent for a profession, they are not problem‐free. In particular, they lend themselves to reification (making something abstract into something concrete and thus, reduce the potential for their full impact), they are time dependent (that is, they are relevant only to the time in which they were formulated), subject to different lenses (that is, they are relevant only to the culture in which they were formulated), and emotionally challenged (that is, they are rarely formulated in a way that encompasses the emotions around the particular situation). An individual's role in a situation is hard to delineate via codes of ethics and, thus, these codes of ethics should be seen as a proposition, rather than as a solution for performance problems regarding ethical challenges.  相似文献
