Towards An Understanding of Muslim American Adolescent High School Experiences     

Derek X. Seward  Shaza Khan 《International journal for the advancement of counseling》2016,38(1):1-11

The researchers conducted a grounded theory study to explore the experiences of Muslim American adolescents in high school. Findings indicate that students had to navigate unique challenges because of their religious faith, but those obstacles presented opportunities to confront bias and discrimination. Recommendations for how school counselors can support the development of Muslim American adolescents are presented.  相似文献

Foreign patent flows to and from the United Kingdom     

Derek L. Bosworth 《Research Policy》1984,13(2):115-124

A substantial part of the stock of technological knowhow in any given country is determined by foreign companies. Flows of technology are reflected in part by the international pattern of patenting behaviour. This paper examines both the patent applications in the UK by foreign countries and UK patent applications abroad. It concludes that each country is exposed to a subset of world-wide technology determined by the profitability of transfer of new knowhow. Profitability is affected by the size of potential supply of new inventions in donor countries, by the attractiveness of markets for knowhow in recipient countries and by the costs of transfer.  相似文献   

Framing the Problem: effects of wording on children's statistical inferences     

Sik Hung Ng  Margaret‐Ellen Pipe  Bruce Beath  Derek Holton 《教育心理学》1999,19(4):489-499

ABSTRACT A total of 96 children aged 11 to 12 years were given statistical inference problems (base‐rate and law of large numbers) designed to test the effects of wording on their answers. The wording of the problems was manipulated to make the information on base‐rates and on the law of large numbers either more salient or less salient. The latter condition was established by adding extraneous information to base‐rates, or, in the case of the law of large numbers, making the context unfamiliar or focusing choice on a particular person rather than on the group. A significant main effect of wording was found across all problems in favour of the salient condition. The results indicated that the children had a high level of statistical intuition and that they knew when to reason statistically and when not to.  相似文献   

Sport education and extracurricular sport participation: an examination using the trans-contextual model of motivation     

Wallhead TL  Hagger M  Smith DT 《Research quarterly for exercise and sport》2010,81(4):442-455

In this study, we used the trans-contextual model of motivation (TCM) to examine the effect of Sport Education (SE) on students' participation in a voluntary lunch recess sport club. A total of 192 participants (ages 9-14 years) completed measures of the TCM constructs before and after a 12-week SE intervention period. Participants had the opportunity to participate in weekly, voluntary lunch recess sport club sessions during the intervention period. SE elicited a moderate increase in autonomous motives in physical education. The TCM accounted for a significant proportion of the explained variance in lunch recess sport club intention and participation. Autonomy-supportive curricular models, such as SE, may have the potential to facilitate transfer of motivation and participation in physical activity from a physical education to an extracurricular context.  相似文献   

TEACHERS’ MISCONCEPTIONS ABOUT THE EFFECTS OF ADDITION OF MORE REACTANTS OR PRODUCTS ON CHEMICAL EQUILIBRIUM     

Derek Cheung  Hong-jia Ma  Jie Yang 《International Journal of Science and Mathematics Education》2009,7(6):1111-1133

The importance of research on misconceptions about chemical equilibrium is well recognized by educators, but in the past, researchers’ interest has centered on student misconceptions and has neglected teacher misconceptions. Focusing on the effects of adding more reactants or products on chemical equilibrium, this article discusses the various misconceptions held by high school teachers. A misconception test was administered to two samples of chemistry teachers in Nanjing, China. Of the 109 teachers who participated in the test, only one understood that adding more CS₂ gas to the equilibrium system CS₂(g) + 4H₂(g) ⇌ CH₄(g) + 2H₂S(g) at constant pressure and temperature can shift the equilibrium to the reactant or product side, depending upon the amount of CS₂ in the initial equilibrium system. Most of the teachers relied on Le Chatelier’s principle and thus made erroneous predictions. The misconception test also revealed that those teachers who managed to compute equilibrium constants had a limited conceptual understanding of chemical equilibrium. Implications of these findings for teacher education and chemistry curriculum development are discussed.  相似文献   

The impact of library services in primary care trusts in NHS North West England: a large‐scale retrospective quantitative study of online resource usage in relation to types of service     

Katherine Bell  Steven William Glover  Colin Brodie  Anne Roberts  Colette Gleghorn 《Health information and libraries journal》2009,26(2):136-142

Background: Within NHS North West England there are 24 primary care trusts (PCTs), all with access to different types of library services. This study aims to evaluate the impact the type of library service has on online resource usage. Methodology: We conducted a large‐scale retrospective quantitative study across all PCT staff in NHS NW England using Athens sessions log data. We studied the Athens log usage of 30 381 staff, with 8273 active Athens accounts and 100 599 sessions from 1 January 2007 to 31 December 2007. Results: In 2007, PCTs with outreach librarians achieved 43% penetration of staff with active Athens accounts compared with PCTs with their own library service (28.23%); PCTs with service level agreements (SLAs) with acute hospital library services (22.5%) and with no library service (19.68%). This pattern was also observed when we looked at the average number of Athens user sessions per person, and usage of Dialog Datastar databases and Proquest full text journal collections. Discussion: Our findings have shown a correlation of e‐resource usage and type of library service. Outreach librarians have proved to be an efficient model for promoting and driving up resources usage. PCTs with no library service have shown the lowest level of resource usage.  相似文献   

Qualitative Differences Between Learning Environments Using Videos in Small Groups and Whole Class Discussions: A Preliminary Study in Physics     

Ashleigh Mayo  Manjula D. Sharma  Derek A. Muller 《Research in Science Education》2009,39(4):477-493

Interactivity, group learning and student engagement are accepted as key features of social constructivist learning theories. The challenge is to understand the interplay between such features in different learning environments. This study focused on the qualitative differences between two interventions—small-groups and whole-class discussions. In both interventions, three short video slices on the abstract topic ‘the physics of superconductivity’ were interspersed with the different discussion styles. The video slices are based on the Bruner stages. Twenty-nine first year university physics students completed a pre-test, underwent the intervention and completed a post-test. The remainder of the data were collected from student drawings, video recordings, observer notes and facilitator feedback. Results indicate that the use of the video slices in both interventions were successful in changing students’ understandings of superconductivity. However, the small groups treatment tended to facilitate questioning, meaning-making and subsequent changes of ideas more so than the whole class discussions. Implications for research and practice are discussed.  相似文献
