The evaluation of solutions is a major unresolved issue for all those involved in e-learning. In this paper we illustrate the importance of context by means of a qualitative comparison of two e-learning prototype implementations--an action research case undertaken in conjunction with a major German insurance company; and a more experimental approach undertaken during an undergraduate university course, where a variety of learning strategies were tested. Despite the apparent difference of the two prototypes, we believe that evaluators from both sides can learn from one another's experiences--and that the differences lie in the ranking of the evaluation categories, rather than in their in/exclusion. We conclude that we can learn from other evaluation projects--not in terms of operational evaluation criteria, but in terms of understanding evaluation categories and their integrated nature within the e-learning organisation. 相似文献

This paper pursues three objectives. First, it seeks to identify the determinants of performance of German motion pictures in terms of cinema admissions and producers’ rates of return. Second, against the background of heavy subsidization of the German film industry, it discusses two types of subsidy allocation: committee principle allocation and reference principle allocation. Third, the profitability of the industry is considered as the presumed economic non-viability of the industry constantly recurs in the public debate as an argument for subsidies. 相似文献

Workplace learning circumscribes processes leading to the development of competencies and skills through daily work. It is of increasing importance for many modern enterprises, which consider themselves as being learning organisations, to make use of the potential of their employees in order to be competitive within global markets. Dealing with mistakes is a particular strategic source of workplace learning for such organisations, because contemporary work often is so complex that mistakes cannot be avoided. A workplace culture of learning from mistakes stands to maximise them as effective learning experiences. Two empirical studies were conducted in order to investigate conditions of learning from mistakes in everyday work in modern enterprises. Study 1 assessed the role of individual mistake orientation using a questionnaire. Through the comparison of 52 managers and 108 working staff members the variability of learning from mistakes was investigated. Study 2 assessed how communities of practice deal with mistakes and what is done to prevent them occurring in future. Semi-structured interviews were conducted with 28 subjects, 14 managers and 14 working staff members. Study 1 revealed a greater appraisal of mistakes as opportunities for learning by managers, but no differences in related strategies and emotions. Study 2 revealed that mistakes are constructively dealt with, and that they are appraised as learning opportunities. Both studies indicate the presence of a culture of learning from mistakes in everyday work. Conclusions are drawn about organisational and personal prerequisites for this kind of workplace learning. 相似文献

Engagement,conduct of life and dropouts in the Danish vocational education and training (VET) system
Klaus Nielsen 《Journal of Vocational Education & Training》2016,68(2):198-213
This study provides support for the idea that school engagement is a central concept when trying to understand the dropout process. One of the strengths of this concept is that it involves understanding dropping out as a process, rather than as an event. However, the concept of school engagement also presents a number of problems. It tends to be functionalistic in nature: Processes of students’ school engagement and disengagement are partly the consequences of institutional initiatives – for example, how teachers act or how the school environment is organised. Furthermore, mainstream dropout researchers formulate the concept of engagement both simplistically and mechanistically by seeing engagement as something that the students possess to varying degrees. Inspired by critical psychology, this study includes a different concept of student engagement: We must take the students’ life conduct as the point of departure when approaching their school engagement and decision to drop out. The theoretical claims in the paper are substantiated by empirical results from 160 interviews with vocational educational and training (VET) students in the Danish VET system, and this paper will show how school engagement is closely related to the events in the other contextual settings of students’ lives. 相似文献

AbstractResearch shows that students face a range of difficulties when using the Internet to solve information problems. Using a quasi-experimental design, we tested a strategy to improve Chilean 10th graders’ skills for information problem solving using the Internet (IPS-I). The intervention was based on a workshop in which students learned IPS-I strategies and solved information problems using a customized Internet search software package. Results showed that members of the experimental group changed their search behavior and improved the quality of their products. However, no correlation between the number of search actions and product quality was found. Based on this, we highlight the potential of combining teaching strategies to improve specific search skills and the use of customized search tools with embedded functionalities that foster good search techniques. 相似文献

We compared the effects of using passive-heat maintenance, explosive activity or a combination of both strategies during the post-warmup recovery time on physical performance. After a standardised warmup, 16 professional rugby union players, in a randomised design, completed a counter-movement jump (peak power output) before resting for 20 min and wearing normal-training attire (CON), wearing a passive heat maintenance (PHM) jacket, wearing normal attire and performing 3 × 5 CMJ (with a 20% body mass load) after 12 min of recovery (neuromuscular function, NMF), or combining PHM and NMF (COMB). After 20 min, participants completed further counter-movement jump and a repeated sprint protocol. Core temperature (Tcore) was measured at baseline, post-warmup and post-20 min. After 20 min of recovery, Tcore was significantly lower under CON and NMF, when compared with both PHM and COMB (P < 0.05); PHM and COMB were similar. Peak power output had declined from post-warmup under all conditions (P < 0.001); however, the drop was less in COMB versus all other conditions (P < 0.05). Repeated sprint performance was significantly better under COMB when compared to all other conditions. Combining PHM with NMF priming attenuates the post-warmup decline in Tcore and can positively influence physical performance in professional rugby union players. 相似文献

The impact of perceived wellness on a range of external load parameters, rating of perceived exertion (RPE) and external load:RPE ratios, was explored during skill-based training in Australian footballers. Fifteen training sessions involving 36 participants were analysed. Each morning before any physical training, players completed a customised perceived wellness questionnaire (sleep quality, fatigue, stress, mood and muscle soreness). Microtechnology devices provided external load (average speed, high-speed running distance, player load and player load slow). Players provided RPE using the modified Borg category-ratio 10 RPE scale. Mixed-effect linear models revealed significant effects of wellness Z-score on player load and player load slow. Effects are reported with 95% confidence limits. A wellness Z-score of ?1 corresponded to a ?4.9 ± 3.1 and ?8.6 ± 3.9% reduction in player load and player load slow, respectively, compared to those without reduced wellness. Small significant effects were also seen in the average speed:RPE and player load slow:RPE models. A wellness Z-score of ?1 corresponded to a 0.43 ± 0.38 m·min?1 and ?0.02 ± 0.01 au·min?1 change in the average speed:RPE and player load slow:RPE ratios, respectively. Magnitude-based analysis revealed that the practical size of the effect of a pre-training perceived wellness Z-score of ?1 would have on player load slow was likely negative. The results of this study suggests that monitoring pre-training perceived wellness may provide coaches with information about the intensity of output that can be expected from individual players during a training session. 相似文献

AbstractSo far, academic contributions have widely framed football in Africa as a means for migration from a western point of view. At a time, they presented particular and one-dimensional understandings of transnational links in the realm of football migration between Africa and Europe. Macro-level perspectives which mostly focus on African exploitation and dependency and more recently those that take the players’ agency into account reproduce a Eurocentric view of the phenomenon, while disregarding its local perceptions in African settings. Thus, despite the recent shift from a macro- to a micro-level perspective there is still an analytical gap between the ambitions and experiences of migrating players and economic power relations at play on the one hand and the socio-cultural embedding of the transnational connections in football migration on the other. In order to understand why and how football mobilities are indeed linked to ‘the transnational’ in migration there is a need to localize the phenomenon and investigate how local understandings of migration and mobility are lived and expressed in a transnational sport like football. By taking data from fieldwork among West African football migrants, the paper thus shows the local embedding of transnational football migration practices in the West African context. 相似文献
