Developing Self‐Directed Executive Functioning: Recent Findings and Future Directions          下载免费PDF全文

How do children become increasingly self‐directed across development, achieving their goals without help from others? How might such developments be impacted by societal changes in how children spend their time? Children's abilities to achieve their goals are supported by developing executive functions (EFs), cognitive processes that predict important life outcomes. Efforts to improve children's EFs have benefitted their externally driven executive functioning, where goals and instructions are provided by others. Less is known about self‐directed EF, when children must decide independently what to do and when. We present recent findings demonstrating that children are better at engaging self‐directed EF when they have good understanding of options to choose among, and if they spend time in activities that they play a large role in directing. Within this context, we discuss the potential role of opportunities to plan, mind‐wander, and play, and present the critical next steps in investigating the influence of changing environments on self‐directed EF.  相似文献   

支持开放教育资源项目的方法     

约翰·罗比森  希拉·麦克尼尔  菲尔·巴克  洛娜·坎贝尔  袁莉 《开放教育研究》2010,16(4):52-58

本文考察了英国教育技术互用性标准中心（CETIS）通过支持国家项目（即英国联合信息系统委员会（JISC）和高等教育委员会的英国开放教育资源试点项目,详见http：／／www．jisc．ae．uk／oer）,以促进发布开放教育资源方面的经验,并探索了如何让我们的支持模式对其他相关项目有所启发,并能改编用于鼓励开放课件运动的可持续性技术支持网络。作为一个涵盖英国众多大学的国家层面的创新举措,众多开放教育资源提供者参与了英国开放教育资源（UKOER）,这包括个别教育者、学科联合体和机构。考虑到这种多样性,从一开始我们就意识到没有任何一种技术解决方案能适合所有的项目。因此,也没有委托专门的工具、描述性标准、交流或分发机制（除要求所有制作的资源应该放在国家学习资源库中外,详见http：／／jorum．ae．uk）。为了支持这一项目,我们引导采取不同的方法和形成不同的社群,也许在支持发布开放教育资源方面,任何类似的跨机构创新都将会面临相似的问题。我们的项目支持方法已从具体的细节问题发展到提供基本的支持原则,从而预测其他问题,并推动最佳实践。我们的做法是：通过会议上的技术汇报和讨论机会,以及在博客上发帖,激发讨论;通过技术评论讨论,并记录针对这些公布在网上的讨论的总结性内容,从而调查个别项目的技术选择;针对通过以上方式所发现的问题,以及项目博客上凸显的问题,做出相应的反馈。考虑到如何使这一方法在更广泛的范围内应用,我们也反思了这种公开的工作模式所面临的挑战、这一方法的开支、适应性,以及我们所认为的其在支持开放教育资源管理和传播方面所扮演的角色。  相似文献   

Platelet satellitism in a trauma patient     

Kopcinovic LM  Pavic M 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2012,22(1):130-134

Platelet satellitism (PS) is a rare phenomenon observed in blood smears obtained from blood anticoagulated with EDTA. It is characterised by platelet rosetting around polymorphonuclear neutrophils and in rare cases around other blood cells. PS is a rare cause of pseudothrombocytopenia. References about the phenomenon of PS in medical literature are few. In this report we describe a case of PS fortunately noticed in one trauma patient. Furthermore, we discuss the possible pathophysiological mechanisms of PS proposed in the literature. To our knowledge this is the first case of PS reported in Croatia.  相似文献

Biomechanical analyses of synchronised swimming standard and contra-standard sculling     

Lara Elena Gomes  Vera Diogo  Flávio Antônio de Souza Castro  João Paulo Vilas-Boas  Ricardo J. Fernandes  Pedro Figueiredo 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(4):354-365

Synchronised swimming involves a variety of sculling movements essential for body support and propulsion but its study is scarce. We aimed to biomechanically compare standard and contra-standard sculling techniques, and to observe the relationship between measures. Six synchronised swimmers performed two, 30 s maximal intensity, fully tethered standard and contra-standard sculling motions. Kinetic and kinematic data were obtained using a load-cell and underwater cameras, respectively. Force decreased along both techniques’ bouts, but no differences in-between techniques were noted for any kinetic variables. Standard sculling presented a higher cycle rate and a lower elbow mean angle than the contra-standard sculling (2.4 ± 0.3 vs. 2.0 ± 0.2 cycles/s and 134.1 ± 5.8 and 141.5 ± 4.7°, p < 0.05). In the standard sculling, by removing and maintaining the variation between participants (r _w and r, respectively), the absolute mean force was directly related with cycle rate (r _w  = 0.60) and wrist angular velocity during flexion (r = 0.82), while in the contra-standard condition the force was inversely associated with wrist mean angle (r = ?0.95) and directly with hand speed (r _w  = 0.76), and elbow angular velocity (r _w  ≈ 0.60). Therefore, technique learning and training require different attention by coaches and swimmers.  相似文献   

Building friendship through a cross-cultural mentoring program     

Peter Woods  Arthur Poropat  Michelle Barker  Ruth Hills  Ray Hibbins  Sally Borbasi 《Int J Intercult Relat》2013

This paper examines the efficacy of a short-term mentoring program in building cross-cultural friendships between students at an Australian university. Using a quasi-experimental approach, our study found that the mentoring program (Local Aussie Mentoring Program—LAMP) increased cross-cultural interactions for mentees, but not for mentors. About 45% of both mentors and mentees wished to continue their relationship with mentoring partners after the completion of the mentoring requirements. Mentees spent significantly more time with cross-ethnic friends than did controls after the completion of LAMP. We examined whether multicultural aspects of personality, as measured by the Multicultural Personality Questionnaire (MPQ), would positively correlate with cross-cultural mentoring effectiveness and cross-cultural friendship interactions (the dependent variables). Multicultural personality aspects of mentors (as measured by the MPQ) had significant positive relationships with both mentee and mentor-rated mentoring measures. All mentor MPQ scales showed some significant but small and positive relationships, with mentor friendship items, particularly Open-mindedness, Cultural Empathy and Emotional Stability. We found a significant, positive relationship between mentee Cultural Empathy and Social Initiative with cross-cultural friendship. These results show some partial support for a positive relationship between MPQ scales and cross-ethnic friendships.  相似文献

Time on task in intensive modes of delivery     

Alison Kuiper  Ian Solomonides  Lara Hardy 《Distance Education》2015,36(2):231-245

This paper reports on an investigation into how staff teaching in compressed courses can encourage student engagement and enhance student use of learning time, despite significant restraints of time as well as distance. Typically these courses (described here as units) are expected to have comparable learning outcomes to their full-semester counterparts and provide an opportunity for students to either retake failed units or to acquire credit for their chosen degrees in accelerated time. Organising teaching and learning through intensive modes of delivery may require different approaches to curriculum development and pedagogy compared to traditional unit planning and delivery, especially when the intensive delivery utilises online technologies. This paper explores strategies employed by successful intensive mode teachers in the development and delivery units for maximised student engagement. It concludes that many of these strategies are equally applicable in online and distance education regardless of the unit being intensive or otherwise.  相似文献
