Over the last decade, researchers have developed sophisticated online learning environments to support students engaging in dialogic argumentation. This review examines five categories of analytic frameworks for measuring participant interactions within these environments focusing on (1) formal argumentation structure, (2) conceptual quality, (3) nature and function of contributions within the dialogue, (4) epistemic nature of reasoning, and (5) argumentation sequences and interaction patterns. Ultimately, the review underscores the diversity of theoretical perspectives represented within this research, the nature of dialogic interaction within these environments, the importance of clearly specifying theoretical and environmental commitments throughout the process of developing or adopting an analytic framework, and the role of analytic frameworks in the future development of online learning environments for argumentation.

Factors underlying students' decisions to use mobile devices in clinical settings

University policies prohibiting use of mobile devices by medical students during clinical placements are contradicted by regular use by physicians. Consequently, many students use their mobile devices, which can be beneficial for learning but may put patient privacy at risk. This study explores the reasons underlying students' decisions about using mobile devices in clinical settings. We used a mixed-methods sequential explanatory design involving a questionnaire and focus groups. Qualitative data from the questionnaire and focus groups was analysed through thematic analysis. We found students were aware of the risks mobile devices posed to professionalism and medical practice. Despite prohibitions, many made individual decisions to use mobile devices because the benefits outweighed the risks. These students were influenced by an organised, strategic approach to learning and a motivation to comply with the beliefs and behaviours of their medical teams and conform to physicians' directives in order to participate in their community of practice. Many students appear to be transferring everyday use of mobile devices to clinical settings. There is a need to understand and promote aspects of learning that are enhanced by mobile devices in clinical settings, while articulating clear guidelines and boundaries compatible with the professional behaviour expected of students.  相似文献

Knowledge of bout duration influences pacing strategies during small-sided games     

John Andrew Sampson  Hugh Head Kelsham Fullagar  Tim Gabbett 《Journal of sports sciences》2015,33(1):85-98

This investigation examines pacing during intermittent team sports. Sixteen junior Rugby League players participated in eight different small-sided offside touch games. All games were 24 min, but bout durations differed in continuous (1 × 24 min) or repeated (2 × 12, 3 × 8, 4 × 6, 6 × 4, 8 × 3, 12 × 2 or 24 × 1 min) formats. Repeat bouts were interspersed by 2 min of passive rest, and participants were informed of the bout duration immediately prior to the game. Heart rates, ratings of perceived exertion and data gathered from global positioning system devices were used to investigate the pacing strategies employed within each game. No significant (P > 0.05) between-game differences were observed in total distance; however, during the 1-min bouts, high-speed movement was significantly (P < 0.05) increased, during the first and second quarters of the 24 × 1-min game compared to all other formats (effect size range: 0.75 ± 0.61–1.38 ± 0.47). Furthermore, the rate of decline in high-speed movement over-time was greatest during the 24 × 1-min game with large differences observed between the first and third quarters (effect size: 0.90 ± 0.58). Greater moderate-speed (effect size range: 0.62 ± 0.63–1.56 ± 0.40) and less low-speed (effect size range: 0.69 ± 0.62–1.54 ± 0.40) distances were also observed during the 1-min bouts, yet heart rates were higher during the continuous 1 × 24-min game. Pacing strategies during intermittent activities are influenced by the number and duration of exercise bouts. Practitioners should consider within-game bout durations when prescribing game-based activities to improve aerobic capacity.  相似文献

UNIVERSITY‐BASED ADULT DAY CARE CENTER FOR RESEARCH AND TRAINING: DESIGN,FUNDING, AND PROGRAMMATIC ISSUES     

Shirley S. Travis  Puspa Das 《Educational gerontology》2013,39(6):557-565

In the early 1980s, the College of Human Resources at Virginia Polytechnic Institute and State University began a visioning process to plan its educational agenda for the 21st century. One of the more pressing issues targeted for educational intervention was community‐based long‐term care. Ten years later, a licensed, Medicaid‐certified adult day health center is fully operational on the university campus, providing a myriad of research, teaching, and public service opportunities for faculty and students. Center design, funding, and programmatic issues are discussed.  相似文献   

Deliberative Democracy, Diversity and the Challenges of Citizenship Education     

Penny Enslin  Shirley Pendlebury  & Mary Tjiattas 《Journal of Philosophy of Education》2000,35(1):115-130

For democracies to thrive, citizens have to be taught to be democrats. How do people learn to be democrats in circumstances of diversity and plurality? We address this question via a discussion of three models of deliberative democracy: public reason (as exemplified by Rawls), discursive democracy (as exemplified by Benhabib) and communicative democracy (as exemplified by Young). Each of the three theorists contributes to an account of how to educate citizens by teaching talk. Against a commonly held assumption that the protection of diversity in a pluralist democracy requires a thin conception of citizenship education, we defend a thick conception that simultaneously fosters autonomy and participation without sacrificing tolerance of diversity.  相似文献
