Background: Literature for a systematic review on the student experience of e‐learning is located across a range of subject areas including health, education, social science, library and information science. Objectives: To assess the merits and shortcomings of using different search techniques in retrieval of evidence in the social science literature. Methods: A conventional subject search was undertaken as the principal method of identifying the literature for the review. Four supplementary search methods were used including citation searching, reference list checking, contact with experts and pearl growing. Results: The conventional subject search identified 30 of 41 included references; retrieved from 10 different databases. References were missed by this method and a further 11 references were identified via citation searching, reference list checking and contact with experts. Pearl growing was suspended as the nominated pearls were dispersed across numerous databases, with no single database indexing more than four pearls. Conclusions: Searching within the social sciences literature requires careful consideration. Conventional subject searching identified the majority of references, but additional search techniques were essential and located further high quality references. 相似文献

The authors investigated ethnicity, self‐construal, and distress among African American and Asian American college students. African American students expressed more salient independent self‐construals, whereas Asian American students expressed more salient interdependent self‐construals. As hypothesized, among African American participants, distress was positively related to interdependent self‐construal and negatively associated with independent self‐construal. Contrary to prediction, the same pattern was found for Asian American participants. Multicultural clinical practice implications are presented. 相似文献

Creativity assessment commonly uses open-ended divergent thinking tasks. The typical methods for scoring these tasks (uniqueness scoring and subjective ratings) are time-intensive, however, so it is impractical for researchers to include divergent thinking as an ancillary construct. The present research evaluated snapshot scoring of divergent thinking tasks, in which the set of responses receives a single holistic rating. We compared snapshot scoring to top-two scoring, a time-intensive, detailed scoring method. A sample of college students (n = 226) completed divergent thinking tasks and measures of personality and art expertise. Top-two scoring had larger effect sizes, but snapshot scoring performed well overall. Snapshot scoring thus appears promising as a quick and simple approach to assessing creativity. 相似文献

Sleep is now considered as a new frontier in performance enhancement. This article presents background content on sleep function, sleep needs and methods of sleep investigation along with data on the potential effects of Ramadan fasting on sleep in normal individuals and athletes. Accumulated sleep loss has negative impacts on cognitive function, mood, daytime sleepiness and performance. Sleep studies in athletes fasting during Ramadan are very rare. Most of them have demonstrated that during this month, sleep duration decreased and sleep timing shifted. But the direct relation between sleep changes and performance during Ramadan is not yet elucidated. Objective sleep patterns can be investigated using polysomnography, actigraphy, and standardised questionnaires and recorded in daily journals or sleep logs. The available data on sleep indicate that team doctors and coaches should consider planning sleep schedule and napping; implementing educational programmes focusing on the need for healthy sleep; and consider routine screening for sleep loss in athletes of all age groups and genders. 相似文献

Aerobically fit children outperform less fit peers on cognitive control challenges that involve inhibition, cognitive flexibility, and working memory. The aim of this study was to determine whether, compared with less fit children, more fit 9- and 10-year-old pre-adolescents exhibit superior performance on a modified compatible and incompatible flanker task of cognitive control at the initial time of fitness testing and approximately one year later. We found that more fit children demonstrated increased flanker accuracy at both test sessions, coupled with a superior ability to flexibly allocate strategies during task conditions that required different amounts of cognitive control, relative to less fit children. More fit children also gained a speed benefit at follow-up testing. Structural MRI data were also collected to investigate the relationship between basal ganglia volume and task performance. Bilateral putamen volumes of the dorsal striatum and globus pallidus volumes predicted flanker performance at initial and follow-up testing one year later. The present findings suggest that childhood aerobic fitness and basal ganglia volumes relate to cognitive control at the time of fitness testing and may play a role in cognitive performance in the future. We hope that this research will encourage public health and educational changes that will promote a physically active lifestyle in children. 相似文献

Management innovation and the consultants who promote and support it are both typically associated with the ‘new’, with departures from the norm and from standard approaches. Indeed, standardization is often seen as an impediment to innovation, especially in the current ‘post-bureaucratic’ era. This article challenges such a view, arguing that consultant-led management innovation is often highly standardized. Based upon qualitative research into internal consultancy in large business organizations, both standardizing agendas and standardized methods are identified from a range of consultant-led management innovation programs. The analysis then points to some of the structural and cultural features of organizations that lead to managers favouring incremental, standardized approaches to change, even if these are often contested. In conclusion, the article points to the need to consider a range of different dimensions in the relationship between standardization and management innovation. 相似文献

In marginal regions of Mexico, grass roots educational innovations have often provided what the official system has not: basic education that responds to the cultural particularities of such populations while satisfying the national curriculum's requirements. The way these have developed, the article argues, offers valuable lessons for a new devolved, more democratic and sustainable form of educational provision in which the school is the heart of the educational system. 相似文献

This study investigated the effect of metaconceptual teaching interventions on students’ understanding of force and motion
concepts. A multimethod research design including quasi-experimental design and case study designs was employed to compare
the effect of the metaconceptual activities and traditional instruction and investigate students’ reactions to metaconceptual
teaching interventions. The participants (45 high school students in the USA) were enrolled in one of the two physics classes
instructed by the same science teacher. In the experimental group, students’ engagement in metaconceptual knowledge and processes
was facilitated through various instructional activities, including poster drawing, journal writing, group debate, concept
mapping, and class and group discussions. These activities were intended to facilitate students’ engagement in (a) becoming
aware of their existing and past conceptions, associated beliefs, everyday experiences, and contextual differences, (b) monitoring
their understanding of the new conception, the changes in ideas, and the consistency between existing and new conceptions,
and (c) evaluating the relative ability of competing conceptions to explain a physical phenomenon. In the comparison group,
the same content knowledge was explained by the teacher along with the use of laboratory experiments, demonstrations, and
quantitative problem solving. Students’ reactions to the designed instructional activities indicated that metaconceptual teaching
interventions were successful in facilitating students’ engagement in several types of metaconceptual functioning. The results
showed that students in the experimental group had significantly better conceptual understanding than their counterparts in
the comparison group and this positive impact remained after a period of 9 weeks. 相似文献

To succeed in a period of change, German book publishers need to adopt innovations, e.g., implement e-books into their product portfolio. Yet, in the book industry, the adoption of new technologies is not commonplace: Despite being the second biggest book market worldwide, only 1.2 % of all published books in Germany are available as e-books. This problem leads us to investigate the factors that determine whether publishing companies decide in favor or against entering the e-book market. Based on a standardized survey of more than 240 German publishing houses, barriers to innovation adoption are examined from a micro, meso and macro perspective. Our main findings show that individual characteristics of management and the company’s corporate culture strongly predict adoption. Also, organizational communication seems to be critical. Taking this into account, the key resource to enable innovation seems to be information underlining the necessity of communities of practice. 相似文献
