Sport-specific and non-specific practice of strong and weak responders in junior and senior elite athletics – A matched-pairs analysis     

Arne Güllich 《Journal of sports sciences》2018,36(19):2256-2264

Elite track and field athletes with greater and lesser multi-year performance improvement were compared regarding their developmental sport-specific and non-specific, organised (coach-led) and non-organised (peer-led) sporting activities. Athlete pairs were matched on gender, discipline and baseline performance in competitions (at 13/19 years). Their unequal subsequent performance development during junior (13–17 years; n = 138) and senior (19–23+ years; n = 80) age ranges defined “strong responders” and “weak responders”. Analyses revealed that junior-age strong responders accumulated more organised practice in athletics than weak responders, while the amounts of all other types of activities were indifferent. Senior-age strong responders did not accumulate a greater total sum of all kinds of sport activities or greater amounts of organised practice in athletics or non-organised involvement in athletics or other sports than weak responders. But they engaged in more organised practice and competitions in other sports over more years (9 vs. 2 years) and specialised in athletics at a later age than weak responders (16 vs. 11 years). The results were also robust among senior international medallists vs. national medallists. The findings are reflected relative to the hypotheses of “multiple sampling and functional matching”, “learning transfer as preparation for future learning” and “authenticity of variable learning experiences”.  相似文献   

Teacher preferences for collaborative relationships: Relationship to efficacy for teaching in prevention-related domains     

Gale M. Morrison  Phylis Wakefield  Dorlene Walker  Scott Solberg 《Psychology in the schools》1994,31(3):221-231

Recent movements in educational reform call for increased collaborative activities among school personnel. The present study examines student and practicing teacher preferences for modes of working on a variety of student-related concerns and relationships with personal and general efficacy for teaching in prevention-related areas. Elementary and secondary student teachers and practicing teachers were asked to rate their preference for working on student academic, behavioral, and self-esteem problems. The range of working preferences included working with other professionals (collaborative), letting other professionals handle the problem (expert), and working alone. These working preferences were found to vary according to teacher level of experience and grade level of teaching. Significant relationships were found between collaborative work preferences and personal teaching efficacy.  相似文献   

Diversity of Students' Views about Evidence,Theory, and the Interface between Science and Religion in an Astronomy Course     

Nancy W. Brickhouse  Zoubeida R. Dagher  William J. Letts IV  Harry L. Shipman 《科学教学研究杂志》2000,37(4):340-362

Arguments for teaching about the nature of science have been made for several decades. The most recent science education policy documents continue to assert the need for students to understand the nature of science. However, little research actually explores how students develop these understandings in the context of a specific course. We examine the growth in students' understanding about the nature of astronomy in a one‐semester college course. In addition to student work collected for 340 students in the course, we also interviewed focus students three times during the course. In this article we briefly describe class data and discuss in detail how five students developed their ideas throughout the course. In particular, we show the ways in which students respond to instruction with respect to the extent to which they (a) demand and examine evidence used for justifying claims, (b) integrate scientific and religious views, and (c) distinguish between scientific and nonscientific theories. © 2000 John Wiley & Sons, Inc.

Caliphal Imperialism and Ḥijāzī elites in the second/eighth Century     

Harry Munt 《Al-Masaq: Islam & the Medieval Mediterranean》2016,28(1):6-21

ABSTRACT

This article contributes to the debate over the effectiveness with which late Umayyad and early ?Abbāsid caliphs negotiated their respective rights and duties with provincial elites during the second/eighth century. The focus is on the relationships that evolved between the caliphs and those elite families residing in the ?ijāz whose ancestors had helped to establish the Muslim community and the early caliphal empire in the mid-first/seventh century. The article's analysis centres on a series of four revolts in the ?ijāz over the second/eighth century and examines developments in the enthusiasm with which local elites either supported or opposed those revolts. This discussion demonstrates that, aside from a brief period during the first decades of ?Abbāsid rule, Umayyad and ?Abbāsid caliphs during the second/eighth century were actually quite successful at inspiring loyalty among the local elites of the ?ijāz.  相似文献
