An assessment was conducted of a web-based formative peer assessment system (WFPAS) emphasizing learners’ metacognitive awareness for their performance in ill-structured tasks. Results indicate that the WFPAS group achieved significantly higher scores for metacognitive awareness and performance in ill-structured tasks than the traditional peer assessment group and that a traditional peer assessment group achieved higher scores for metacognitive awareness than a self-assessment group. In addition, the WFPAS group showed significantly higher scores in motivation than the traditional peer assessment group. Results are explained from the perspective of peer interaction and scaffolding. The potential challenges and implications of the WFPAS are discussed. 相似文献

As exhibitions are known to play important roles in marketing and sales promotion, the exhibition industry has grown significantly not only in the exhibition event size and frequency but also in the number of participating firms and visitors. While the challenge in assessing economic returns from exhibitions is being studied, it is agreed that the eventual success of an exhibition resides largely in its ability to meet the visitors’ needs. Visitors use an exhibition as a source of information when searching for products or services. Though an exhibition provides an information-rich environment, however, visitors often get lost in the abundance of information. A specialized recommender system can be a good solution to information overload as it can guide visitors to right exhibition booths and help them collect necessary information. Traditional collaborative-filtering recommender systems, however, use only customers’ rating or purchase records so that they do not capture exhibition visitors’ temporal visit sequences and dynamic preferences. Moreover, due to the computation overhead, they cannot generate real-time recommendation in ubiquitous environments for exhibitions. In order to overcome these drawbacks, this study proposes a booth recommendation procedure that takes into consideration not only booth visit records but also visit sequences. Experiment results show that the proposed procedure achieves higher recommendation accuracy, faster computation, and more diversity than a typical collaborative-filtering recommender system. From the results, we conclude that the proposed booth recommendation procedure is suitable for real-time recommendation in ubiquitous exhibition environments. 相似文献

In this study, young, middle-aged, and elderly adults read two different history texts. In the knowledge advantage condition, readers read a history text about an event that was well-known to readers of all ages but most familiar to elderly adults. In the no advantage condition, readers read a history text about a political situation of a country that no age groups knew much about. After reading the text, readers recalled and interpreted the texts. Comparison of the recall and the interpretation performance showed that while recall was best in the young group and declined with age, interpretation did not. The middle-aged and elderly adults generated interpretations that were equally deep and more synthetic than those of the young adults. They also generated interpretations with more diverse rationale statements. As for the effect of knowledge advantage its effect on text recall was straightforward: although not significant, age-group differences in recall were smaller in the knowledge advantage condition than in the no advantage condition, suggesting that age-related decline in recall can be moderated by older adults' knowledge advantage. The effect of knowledge advantage on text interpretation was less clear-cut. While knowledge facilitated interpretations, the facilitation was not uniform across different measures of interpretations, suggesting a complex interaction between text interpretation and knowledge. 相似文献

We aimed to investigate the step-to-step spatiotemporal variables and ground reaction forces during the acceleration phase for characterising intra-individual fastest sprinting within a single session. Step-to-step spatiotemporal variables and ground reaction forces produced by 15 male athletes were measured over a 50-m distance during repeated (three to five) 60-m sprints using a long force platform system. Differences in measured variables between the fastest and slowest trials were examined at each step until the 22nd step using a magnitude-based inferences approach. There were possibly–most likely higher running speed and step frequency (2nd to 22nd steps) and shorter support time (all steps) in the fastest trial than in the slowest trial. Moreover, for the fastest trial there were likely–very likely greater mean propulsive force during the initial four steps and possibly–very likely larger mean net anterior–posterior force until the 17th step. The current results demonstrate that better sprinting performance within a single session is probably achieved by 1) a high step frequency (except the initial step) with short support time at all steps, 2) exerting a greater mean propulsive force during initial acceleration, and 3) producing a greater mean net anterior–posterior force during initial and middle acceleration. 相似文献

While university‐level education is increasingly recognized as an important component of sustainable approaches to development, little empirical research has been done on the impact of sustainability education on student behavior. This study relies on an evidence‐based research approach to better understand how graduate coursework on sustainable development can facilitate learning and transform the perceptions and reported behavior of class participants. Specifically, the authors use ecological footprint analysis in an interdisciplinary graduate‐level course on sustainable development to make statistical conclusions about the degree to which education on sustainability influences students’ daily consumption patterns. The results of this study suggest that graduate‐level education can significantly increase the degree to which students behave in a sustainable manner as measured by their ecological footprints. 相似文献

Charitable donations made by celebrities are being increasingly reported by news media in South Korea. This experimental study has examined the effects of celebrities’ prior reputations, and the duration and type of charitable donation they perform, on young participants’ evaluations of these celebrities (i.e. motive attribution, attitudes toward the celebrities, and related purchase intentions). The results ascertained the main effects of prior reputation and duration and type of donation on the dependent variables. Most notably, the results also found the interaction effect of duration and type of donation on the participants’ evaluation of motive attribution. That is, participants who were exposed to news stories concerning celebrities’ volunteer efforts, or monetary contributions that involve volunteer efforts, performed over long periods of time reported the highest level of motive attribution. Based on these results, this study discussed theoretical and practical implications. 相似文献

For older adults, participating in leisure activities has psychosocial benefits, increases social interactions, and promotes well-being. Among various leisure activities, pickleball is an activity that fosters positive social interaction and health benefits in older adults. Pickleball is regarded as one of the fastest growing sports in the USA, and it is reported to be popular among people of all ages, especially among older adults. The purpose of this study was to gather demographic details of older pickleball participants and elucidate the psychosocial benefits of playing the sport, such as life satisfaction, optimism, and social integration. To this end, we gathered information from 153 older adults who competed in pickleball tournaments. Multivariate analysis of variance and Hotelling’s T2 test were used to compare the differences that emerged in experiential factors such as life satisfaction, optimism, and social integration among the different demographic characteristics. The results showed that life satisfaction was significantly different among the following three age groups: 50–59 years, 60–69 years, and ≥70 years. Results of Hotelling’s T2 test showed a significant difference in social integration between male and female participants. The test also revealed a significant difference in terms of life satisfaction between retired and employed participants. The results suggest that playing pickleball can be an enriching leisure activity for retirees and may help them cope with the transition that retirement typically entails. 相似文献

Between 1992–2011, peer-reviewed research on the Research Consortium's annual program has been published in abstract form in the Research Quarterly for Exercise and Sport. On the basis of frequency, high-visibility institutions, researchers, and sub-disciplinary categories were identified. Data were extracted from each abstract (N?=?5,587). On average, 279 (SD?=?39) abstracts were published annually. The highest visibility institution was Texas A&M University, College Station; individual researcher, Weimo Zhu; and sub-disciplinary area, Pedagogy. Twelve of the top 20 institutions identified in this study took part in the most recent ranking of doctoral programs conducted by the National Academy of Kinesiology, with the Spearman's rho correlation being .66. These results may inform the Research Consortium's and the American Alliance for Health, Physical Education, Recreation and Dance's strategic planning efforts. Those interested in pursuing graduate degrees in the field and those who advise others about potential institutions and faculty mentors to study with may also benefit from this work. However, in doing so, a judicious interpretation of the results must be applied, as many factors should be considered when selecting a graduate program or mentor to study with, especially for those seeking research careers. Additional discussion points also emerged. 相似文献
