Field dependence–independence as visuospatial and executive functioning in working memory: implications for instructional systems design and research     

Kent A. Rittschof 《Educational technology research and development : ETR & D》2010,58(1):99-114

Field dependence–independence (FDI) has long been conceptualized and discussed as a cognitive style relevant to numerous educational approaches and outcomes. However, the FDI construct is most often measured as a cognitive ability, as opposed to a style, using instruments such as the Group-Embedded Figures test (GEFT) or the Hidden Figures Test (HFT). Specifically, FDI is typically measured as visuospatial ability and executive functioning in working memory. While measurement and use of FDI within psychological and educational research has often resulted in misleading or inconsistent discussion about cognitive styles, this review examines how the long history of FDI research continues to be relevant to contemporary instructional contexts. A broader recognition of FDI as ability is suggested in order to (a) better distinguish ability measurements from those of styles, (b) encourage a reinterpretation and awareness of theoretical connections among past studies that use instruments such as GEFT or HFT, and (c) highlight suggestions for future research and application, particularly with contemporary interactive multimedia learning tools.  相似文献   

Competitive balance trends in elite table tennis: the Olympic Games and World Championships 1988-2016     

Jinming Zheng  Seungmo Kim  Geoff Dickson  Veerle De Bosscher 《Journal of sports sciences》2018,36(23):2675-2683

ABSTRACT

Competitive balance is important because it enhances outcome uncertainty and therefore it promotes spectator interest, and encourages government investment in a sport. This article analyses the distribution of gold medals, medals, medal points and top eight points amongst nations in table tennis from 1988 to 2016 at the Olympic Games and the World Championships respectively. A normalised version of the Herfindahl-Hirschman Index and a coefficient of variation are calculated for each nation’s share of these performance indicators. The key findings are that China dominates both events, with successful female players being more dominant than their male counterparts. The competitive balance for gold medals has declined, whilst there is a trend towards improved competitive balance for top eight points for women, suggesting that more teams are featuring in the top eight (but not necessarily the top three) placings. This research has implications for the development of table tennis competitions. Compared to other racket sports, the issue of competitive imbalance in table tennis is particularly thorny, which threatens the long-term development of this sport. Accordingly, some measures are recommended for the International Olympic Committee and the International Table Tennis Federation to propel a more balanced development of international table tennis.  相似文献   

Dietary nitrate supplementation does not improve cycling time-trial performance in the heat     

Georgina L. Kent  Brian Dawson  Gregory R. Cox  Louise M. Burke  Annette Eastwood  Kevin D. Croft 《Journal of sports sciences》2018,36(11):1204-1211

This investigation examined the effect of beetroot juice (BR) supplementation, a source of dietary nitrate (NO₃^?), on cycling time-trial (TT) performance and thermoregulation in the heat. In a double-blind, repeated-measures design, 12 male cyclists (age 26.6 ± 4.4 years, VO_2peak 65.8 ± 5.5 mL.kg^?1.min^?1) completed four cycling TTs (14 kJ.kg^?1) in hot (35°C, 48% relative humidity) and euthermic (21°C, 52%) conditions, following 3 days supplementation with BR (6.5 mmol NO₃^? for 2 days and 13 mmol NO₃^? on the final day), or NO₃^–depleted placebo (PLA). Salivary NO₃^? and nitrite, core (T_c) and mean skin temperature (T_sk) were measured. Salivary NO₃^? and nitrite increased significantly post-BR supplementation (p < 0.001). Average TT completion time (mm:ss) in hot conditions was 56:50 ± 05:08 with BR, compared with 58:30 ± 04:48 with PLA (p = 0.178). In euthermic conditions, average completion time was 53:09 ± 04:35 with BR, compared with 54:01 ± 04:05 with PLA (p = 0.380). The TT performance decreased (p < 0.001), and T_c (p < 0.001) and T_sk (p < 0.001) were higher in hot compared with euthermic conditions. In summary, BR supplementation has no significant effect on cycling TT performance in the heat.  相似文献   

Get real: making problematic the pathway into the teaching profession     

Catherine Sinclair  Geoff Munns  Helen Woodward 《Asia-Pacific Journal of Teacher Education》2005,33(2):209-222

Learning to be a teacher is a complex and very personal matter that involves transformation from student teacher (pre‐service teacher) to teacher. The pathway to being a teacher is scattered with what appears to be competing tensions in various realities. This paper explores those tensions and realities through the context of two final year integrated field‐ and campus‐based subjects that all pre‐service teachers undertake as they complete their four‐year teacher education journey into the primary (ages 5‐ to 12‐years‐old) teaching profession. We then propose a framework involving a variety of realities that pre‐service teachers face through the recognition and resolution of the tensions these pre‐service teachers experience in the workplace.  相似文献   

Student Drivers and the Fiduciary Duty of School Boards     

James Kent Donlevy  Dianne Gereluk  Jim Brandon  Peggy Patterson 《Interchange》2017,48(2):195-203

Following E.D.G. v. Hammer, Canadian law has held that school boards, although they have a fiduciary duty to their students, do not guarantee the safety of their students from the acts of their employees. The scope of that fiduciary duty is narrow, restricted to a board acting with disloyalty, in bad faith, or in a conflict of interest to its students, which causes them injury. This paper takes the position that the scope of that duty should include cases where a school board’s policy allows students to use their own cars to drive fellow students to school-sponsored functions.  相似文献

图书馆资源共享的目标   总被引：1，自引：0，他引：1  

Alan Kent 《大学图书馆学报》1989,(6):50-58

<正> 引言图书资源共享意味着由若干个图书馆共同发挥作用的一种工作方式。它的目标是为了提供有益的网络效果:1)能够为用户提供更多的资料或服务;2)保证图书馆以较低的费用维持一定水平的服务,或者在不增加费用的情况下增加服务,或者用较少的费用来提供更多的服务。所有这些,如果单独由一个图书馆来做,那花销要大得多。为了实现这些目标,必须对各个参加馆的工作方式加以调整,但是不能影响他们原来的工作职责。这些目标的实现,同样也离不开读者对自身的阅读习惯做些调整。  相似文献   

Attitudes toward Face-to-Face and Online Counseling: Roles of Self-Concealment,Openness to Experience,Loss of Face,Stigma, and Disclosure Expectations among Korean College Students     

Geoff J. Bathje  Eunha Kim  Ellen Rau  Muhammad Adam Bassiouny  Taehoon Kim 《International journal for the advancement of counseling》2014,36(4):408-422

This study examined attitudes toward face-to-face (f2f) and online counseling among 228 Korean college students. In addition, it tested a hypothesized model proposing that general propensities (i.e., self-concealment, openness to experience, and loss of face) would influence counseling-specific expectations (i.e., self-stigma and disclosure expectations), which, in turn, would predict attitudes toward f2f and online counseling. Findings mirrored the results of earlier studies revealing that self-concealment was negatively related to attitudes toward both f2f and online counseling, while openness to experience and disclosure expectations were positively related. However, whereas self-stigma was associated with negative attitudes toward f2f counseling, it was not related to attitudes toward online counseling. In addition, disclosure expectations accounted for f2f attitudes more than online attitudes.  相似文献   

Building a Shared Digital Collection: The Experience of the Cooperating Libraries in Consortium     

Dora Wagner  Kent Gerber 《College & Undergraduate Libraries》2013,20(2-3):272-290

Recognizing the digital opportunities available, the libraries of eight educational institutions in Minnesota built on a previously existing consortial relationship in order to explore the possibility of sharing a Digital Asset Management System (DAMS). This article discusses the experience of these institutions as they chose CONTENTdm and the considerations made when settling on an option viable for a consortium. It elaborates on the shared cost considerations, hardware purchases, and the consortium's experience as it purchased and implemented the software, formalized avenues of communication, and established collection standards. We close by discussing the opportunities, challenges, and rewards experienced by those involved.  相似文献
