Efforts to break the link between the school type attended and the qualification awarded are seen an important step in the modernization of Germany??s tracked secondary school system. However, it remains disputed whether these efforts have reduced social disparities or in fact increased them. This study examined the transition from lower secondary education in academic- and intermediate-track schools to upper secondary education in general and vocational gymnasium schools in the state of Baden-Württemberg. When indicators of parental social background and school-leaving qualifications were controlled, the opening of upper secondary education was found to be associated with a decrease in the social selectivity of upper secondary education for intermediate-track students. At the same time, for those intermediate-track students who were entitled to enter upper secondary education, social background had predictive effects on the transition decision; however, the overall size of these effects was low.  相似文献   

Effects of treadmill running and fatigue on impact acceleration in distance running

The effects of treadmill running on impact acceleration were examined together with the interaction between running surface and runner's fatigue state. Twenty recreational runners (11 men and 9 women) ran overground and on a treadmill (at 4.0 m/s) before and after a fatigue protocol consisting of a 30-minute run at 85% of individual maximal aerobic speed. Impact accelerations were analysed using two lightweight capacitive uniaxial accelerometers. A two-way repeated-measure analysis of variance showed that, in the pre-fatigue condition, the treadmill running decreased head and tibial peak impact accelerations and impact rates (the rate of change of acceleration), but no significant difference was observed between the two surfaces in shock attenuation. There was no significant difference in acceleration parameters between the two surfaces in the post-fatigue condition. There was a significant interaction between surface (treadmill and overground) and fatigue state (pre-fatigue and post-fatigue). In particular, fatigue when running overground decreased impact acceleration severity, but it had no such effect when running on the treadmill. The effects of treadmill running and the interaction need to be taken into account when interpreting the results of studies that use a treadmill in their experimental protocols, and when prescribing physical exercise.  相似文献   

STUDENTS’ SOURCES OF MOTIVATION FOR PARTICIPATING IN SCIENCE FAIRS: AN EXPLORATORY STUDY WITHIN THE CANADA-WIDE SCIENCE FAIR 2008

Science fairs have been for many years a popular school activity in North America. They are a venue for the popularization of science and consequently an important encouragement for the pursuit of careers in science or engineering. However, little is known about students?? perceived motives for participating in local or national science fairs and about the way in which their involvement mediates their interest in science learning and scientific careers. The present study investigates the motivational factors associated with the high school students?? decision to participate in the 2008 Canada-Wide Science Fair, a thoroughly selected and highly motivated group. Our study examines 5 sources of motivation: (1) interest in science content, (2) sense of self-efficacy, (3) assurance of achievement through rewards or gratifications, (4) the social aspect of participating and (5) working strategies to gain scientific knowledge and methods. The understanding of the anticipated benefits participants seek through their involvement in science fairs may have the potential to help science teachers adapt instruction to appeal to a broader range of students in schools, thus nourishing the emergence of more interest in science.  相似文献   

Professional Competence and Intuitive Decision Making: A Simulation Study in the Domain of Emergency Medicine     

Christian Harteis  Barbara Morgenthaler  Christine Kugler  Karl-Peter Ittner  Gabriel Roth  Bernhard Graf 《Vocations and Learning》2012,5(2):119-136

Intuition presents as a crucial component of professional competence for many occupations, including emergency physicians because many of their decisions have to be made quickly. When arriving at the scene of an accident, they promptly have to assess the circumstances and initiate immediate life-saving measures without opportunities for deep analyses of patients’ conditions. Therefore, spontaneous and intuitive decisions are required to solve the problem appropriately, rather than more intentional and time-consuming forms of decision-making. Yet, the efficacy of and processes underpinning these intuitive activities remain far from fully understood or clearly conceptualised. The study reported here aims at revealing the efficacy of such intuition by analysing decision-making behaviour of emergency physicians. Based on patient simulation mannequins, which can be programmed to present specified clinical situations, three groups of participants with different levels of emergency medicine expertise (n ₁  = 10 novices, n ₂  = 10 semi-experts, n ₃  = 10 experts) each addressed two different authentic problem cases. In the first simulation, time pressure was utilised to press participants to decide intuitively. In the second simulation, the participants had to legitimise their decisions without any time pressure in order to generate rational decisions. Whereas no clear difference in the participants’ performances between both cases could be identified, experts and semi-experts performed better than novices in their intuitive decision-making, thereby supporting beliefs about the efficacy of intuition. It is proposed that medical education, as well as other forms of occupational preparation, should consider theories of mental simulations in order to improve surgeons’ professional education.  相似文献   

Using body donor demographics to assist the implementation of donation programs in Brazil          下载免费PDF全文

The use of human material in anatomy education depends upon the generosity of body donors. However, little is known regarding the demographics of body donors in Brazil, where voluntary body donation is a relatively rare phenomenon. Hence, the aim of the present study was to elucidate the demographic profile of applicants to the Body Donation Program (BDP) at the Federal University of Health Sciences of Porto Alegre in Brazil, as well as to assess whether the observed characteristics of body donors are unique to that sample, or if they merely reflect the characteristics of the regional population. Information derived from the specific forms filled out by donors between January 2008 and June 2016 at the time of registration were collected. Data from 416 forms were analyzed. Based on this study, the typical applicant in Brazil is typically a white female (67.4%), over 60 years of age (60.3%), unmarried or single (70.6%), affiliated with a religious group (89.1%), of middle class background (40.4%), who has completed high school and/or holds a university degree (93.8%). The motivation of donors was, in most cases, an altruistic gesture, represented by the desire to help society and science. Elucidating these demographic characteristics of potential donors may help identify the target public to which information regarding body donation campaigns could be directed.

Persecution and behavior: a report of refugee children from Chile     

A Hjern  B Angel  B H?jer 《Child abuse & neglect》1991,15(3):239-248

A Swedish study of 50 newly resettled refugee children from Chile describes the children's experiences of persecution in their home country and coping patterns in the receiving country. Thirty-six children had experiences directly related to persecution, and seven of these had been victims of physical assault for political reasons. Sleep disturbances and dependency were behaviors significantly associated with experiences of persecution. Resettled refugee families need to be approached by concerned professionals as symptoms of trauma in refugee children are often recognized only in the family sphere.  相似文献   

Comments on “the uses of Lawson's test of formal reasoning in the israeli science education context”     

Gabriel Sunday Bomide 《科学教学研究杂志》1991,28(5):463-464

In a recent article that appeared in this journal, Hofstein and Mandler (1985) reported a study which employed the Lawson's (1978) classroom test of formal reasoning to determine, among other things, the relationship between achievement in science and mathematics in a sample of Israeli students. Based on their findings, the authors raised objections to the classroom utility of the test for diagnosing students' developmental levels. The present author, however, argued that the case has not been properly established in view of one major methodological problem which seemed to characterize the study. Accordingly, the plea to abandon Lawson's test of formal reasoning was questioned.  相似文献   

Women mentoring in the academe: a faculty cross-racial and cross-cultural experience     

Precious Guramatunhu-Mudiwa  Roma B. Angel 《Mentoring & Tutoring: Partnership in Learning》2017,25(1):97-118

Two women faculty members, one White from the southeastern United States and one Black African from Zimbabwe, purposefully explored their informal mentoring relationship with the goal of illuminating the complexities associated with their cross-racial, cross-cultural experience. Concentrating on their four-year mentor-mentee academic relationship at a predominantly White institution (PWI), these women employed a dialogic duoethnographic methodology to uncover emerging, nuanced characteristics contributing to the positive nature of their mentoring experience. Calling upon a seminal nine-function mentoring framework focused on advancing mentee personal growth and professional advancement, the authors, engaged in critical interplay of dialogic considerations of their mentoring experiences, relationship, and literature. The authors revealed a distinct cross-cultural and cross-racial journey where each, as participant researcher, uncovered a deeper appreciation for the importance of engaged dialog. Emerging is a complex interplay of understandings about trust, care, and power dynamics as factors in defining mentoring relationships that work for good.  相似文献   

Student Engagement at a Large Suburban Community College: Gender and Race Differences     

Varalakshmi Sontam  George Gabriel 《Community College Journal of Research & Practice》2013,37(10):808-820

Previous research shows that there are individual differences in academic achievement associated with gender and race. Research also suggests that student engagement is an important determinant of student outcomes/achievement. The present study explored student engagement at an extra-large community college. It specifically investigated possible individual differences in student engagement and explored how it maps on to student achievement. As predicted, the results indicate that there are gender and race differences in student engagement—females show greater engagement than males, and African-American students show greater engagement than students of other races. The results are discussed in the context of student achievement as indicated by students’ self-reported GPAs.  相似文献
