A cognitive approach to threshold concepts 总被引:1,自引:0,他引:1
Guy Walker 《Higher Education》2013,65(2):247-263
This paper asks a fundamental question: what is happening inside the mind of the undergraduate during teaching and learning experiences, and how should curricula be designed to support it? A number of concepts lend themselves to providing an answer, principle among which is the relatively recent idea of Threshold Concepts. In this paper we attempt to critically evaluate both the ‘product’ and ‘process’ of Threshold Concepts and subject the idea to a stress test by comparing it to the longer established Schema Theory of Learning. This mapping enabled a novel empirical study involving undergraduate civil engineering students to be performed. The methods derived from Schema Theories of learning provide a set of findings that compliment and strengthen certain key areas of Threshold Concepts, as well as leading to the development of some interesting principles of curriculum design. 相似文献

The purpose of this study was to examine if steps/day taken by middle school students varied based on aerobic fitness classification. Middle school students (N = 223; 112 girls, 111 boys) were assigned to three aerobic fitness categories (HIGH, MOD, LOW) based on results of the FlTNESSGRAM PACER test. Four weekdays of pedometer monitoring determined activity levels (steps/day). Boys accumulated significantly more steps/day than girls, 11,589 +/- 3,270 and 10,232 +/- 2,517 steps/day, respectively; F(1,219) = 16.0, p < .001, eta2 = .055. There were no differences in steps/day between grades. HIGH fit participants accumulated significantly more steps/day, F(2, 217) = 12.2, p < .101, eta2 = .101, than moderately fit and low fit participants (approximately 1,491 and ; 2,867 steps/day, respectively). Middle school students who participated in sports in addition to physical education (PE) accumulated significantly more steps/day (approximately 980 steps/day) than those participating in PE only, F(1, 219) = 10.0, p < .01, eta2 = .044. Although the relationship between physical activity and aerobic fitness was moderate (0.35; p < .01), these data demonstrated significant differences in accumulated steps/day among youth of varying aerobic fitness levels. Whether improved fitness levels were the result of additional activity or the cause of it remains to be determined. Regardless, the fittest middle school students were also the most active and accumulated a significant amount of steps/day through organized extracurricular physical activities. 相似文献

This paper intends to describe the recent experience of a small, rural, two-year technical college. After four decades of success, the college had found itself in a difficult situation with a substantial loss in enrollment and diminished state and local support, coupled with low campus employee morale. In response, the college team closed ranks and rallied in what has become quite a proactive and successful effort to reinvent itself. After nearly six years of working to correct a number of issues that had led to decline, the college gained a general sense of stabilization, made advances in existing and new academic programs and technical innovation, dramatically increased diversity, and enhanced student life opportunities with the addition of an array of successful athletic programs. The college has seen significant increases in enrollment, state and national recognition for technical initiatives, and a collectively positive sense of the future. 相似文献

We argue that for the case of heterogeneous commodities with infrequent tradings, such as paintings, it is relevant to base a price index on hedonic regressions using all sales and not resales only. To support this conclusion we construct a price index for paintings by Impressionists and their followers and compare the various estimators using bootstrapping techniques. 相似文献

Search engines are increasingly going beyond the pure relevance of search results to entertain users with information items that are interesting and even surprising, albeit sometimes not fully related to their search intent. In this paper, we study this serendipitous search space in the context of entity search, which has recently emerged as a powerful paradigm for building semantically rich answers. Specifically, our work proposes to enhance an explorative search system that represents a large sample of Yahoo Answers as an entity network, with a result structuring that goes beyond ranked lists, using composite entity retrieval, which requires a bundling of the results. We propose and compare six bundling methods, which exploit topical categories, entity specializations, and sentiment, and go beyond simple entity clustering. Two large-scale crowd-sourced studies show that users find a bundled organization—especially based on the topical categories of the query entity—to be better at revealing the most useful results, as well as at organizing the results, helping to discover novel and interesting information, and promoting exploration. Finally, a third study of 30 simulated search tasks reveals the bundled search experience to be less frustrating and more rewarding, with more users willing to recommend it to others. 相似文献

AbstractIn April 2014, for the first time since the event was established, over 200 foreign recreational runners participated in the Pyongyang Marathon, which is part of Day of the Sun commemorating the birthday of Kim Il-sung. The decision of the North Korean regime to open the event to foreign amateurs was unusual, thus the paper examines this new approach to the marathon, and to tourism in general, by contextualizing them within an historical perspective. It is argued that tourism policy under Kim Jong-un, the third leader of the ‘Kim dynasty’, was unprecedented in terms of its systematic approach to the development of a meaningful tourism industry while also particularly emphasizing Western tourism and sport tourism. With the inclusion of the marathon into its tourism industry, North Korea strengthened its place in the worldwide trend of sport event tourism, yet the Pyongyang Marathon has stood out by being more about branding a country than a city. In this regard, this sport tourism event has offered the visitors a look into a ‘different normality’, which was indicative to the rationale of the regime that benefited from the attention it drew through its image as ‘unexpected’ and ‘mysterious’. 相似文献
