Networks as Agents of Innovation: Teacher Networking in the Context of Vocational and Professional Higher Education Reforms

The effective implementation of educational reform is an issue that confronts both those that plan and sponsor those reforms and those that are affected by them. This article discusses networking processes in the context of reform in vocational and professional higher education. When exploring failures in educational change processes, issues associated with facilitating the adoption, adaptation and implementation of educational change have not been sufficiently addressed. Here, we use the concept of social innovation, which is relatively new in innovation research, to explain the mechanisms that facilitate educational reform, and emphasise the relationship between interaction and the perception of change. In this paper, we examine how networking among teachers is related to their perception of educational change and how the effective implementation of educational reforms can be influenced by such networking. By differentiating the various types of networks we explore the relationship between networking and educational change. The article is based on the findings of a quantitative survey of 228 Estonian teachers in vocational and professional higher educational schools administered in 2010.     

Effects of a motivational climate inntervention for coaches on young athletes' sport performance anxiety

The mastery approach to coaching is a cognitive-behavioral intervention designed to promote a mastery-involving motivational climate, shown in previous research to be related to lower anxiety in athletes. We tested the effects of this intervention on motivational climate and on changes in male and female athletes'cognitive and somatic performance anxiety over the course of a basketball season. Hierarchical linear modeling analyses revealed that the athletes in the intervention condition perceived their coaches as being more mastery-involving on the Motivational Climate Scale for Youth Sports when compared to athletes in an untreated control condition. Relative to athletes who played for untrained coaches, those who played for the trained coaches exhibited decreases on all subscales of the Sport Anxiety Scale-2 and on total anxiety score from preseason to late season. Control group athletes reported increases in anxiety over the season. The intervention had equally positive effects on boys and girls teams.     

Extra-curricular participation in sports and socio-demographic factors in Spanish adolescents: the AVENA study

The aims of this study were to identify differences between the sexes in extra-curricular participation in sports and to determine its association with body fat and socio-demographic factors in Spanish adolescents. A total of 2165 adolescents (1124 males and 1041 females) aged 13.0-18.5 years from the AVENA Study participated. Participants filled in an ad hoc questionnaire for extra-curricular participation in sports, which was the dependent variable. Independent variables were: age, percent body fat, and father's and mother's educational level and occupation. Chi-square tests and logistic regression were applied. Bivariate analysis showed for male adolescents that age and father's occupation were related to extra-curricular participation in sports. In addition, body fat and mother's education and occupation (all P?相似文献   

Force production in the rugby union scrum

In this study, we examined the relationship between anthropometric, strength and power characteristics of rugby forwards, their body position when scrummaging, and their ability to apply force when scrummaging. Force applied to an instrumented scrum machine was measured for 56 players, both individually and as scrum packs. Measurements of body position for individuals were made by digitizing videotape records of the trials. Forty players subsequently had their anthropometry assessed and completed several strength and power tests. Body mass, each component of somatotype, maximal anaerobic power developed on a cycle ergometer, and isokinetic knee extension strength correlated significantly with individual scrummaging force. A regression model (P < 0.001) including body mass, mesomorphy, maximal anaerobic power and hip angle while in the scrummaging position accounted for 45% of the variance in individual scrummaging force. The packs that produced the largest scrummaging forces were, in general, characterized by a greater pack force to sum of individual force ratio than the packs producing lower forces. Our results emphasize the need for a scrum pack to develop technique and coordination as a unit to maximize scrummaging force.     

Support for Extended Discourse in Teacher Talk With Linguistically Diverse Preschoolers

A study was conducted in a large Head Start organization that serves large numbers of Latino children in order to empirically describe the nature and quality of the classroom language learning environment. By observing 147 literacy-based lessons in 6 classrooms and surveying 167 teachers throughout the organization, we investigated the amount of teachers' use of extended discourse during literacy-based lessons, and when and how Spanish and/or English was used as the medium of communication. Research Findings: Only 22% of the 147 literacy-based lessons observed fostered extended discourse; the most commonly implemented lesson was characterized by a routine format of the teacher talking and the children listening. English was regarded as the language of instruction, whereas Spanish was used mostly to regulate behavior and emotions. By fitting multilevel models to the data, we found that teaching practice was relatively stable across the classrooms. Practice or Policy: More emphasis should be placed on professional training focused on supporting classroom language interactions that foster literacy development and on the use of language that best fosters and facilitates such extended discourse.     

Using iPad tablets for self‐modeling with preschoolers: Videos versus photos

As technology becomes more accessible and acceptable in the preschool setting, teachers need effective strategies of incorporating it to address challenging behaviors. A nonconcurrent delayed multiple baseline design in combination with an alternating treatment design was utilized to investigate the effects of using iPad tablets to display video self‐modeling and activity photos for three preschoolers during circle time. During baseline, all three children demonstrated low levels of engagement and high levels of off‐task behavior compared to peers. The intervention phase consisted of alternating between showing the child the self‐video and photos prior to circle time. A child preference phase was conducted whereby each child self‐selected the video or photo prior to circle time. For all three children both videos and photos led to increased engagement and decreased off‐task behaviors. During the child preference phase, all three children selected the video most frequently. Social validity data demonstrated teacher and child preference for the video self‐modeling condition.     

Coaching performance and leadership behaviours in team sports

The aim of this study was to investigate coaching performance in team sports taking leadership behaviours into focus. To do so, coaching performance was put in a literature-based frame and analysed with reference to a task structure based on the idea of hierarchical planning. The focus of the paper is on a mixed methods multi-strand study using qualitative as well as quantitative threads to develop and verify a set of coaching strategies focussing on teambuilding and team leadership. Qualitative analyses showed that coaches do have a clear understanding of forming and leading a team, which could be shown by a specific set of strategies being used by high performance coaches from different team sports (basketball, football, handball, and volleyball). These strategies could be confirmed in a sequential quantitative study analysing coaches’ and players’ attitudes towards the previously analysed schemes. The results of this study are discussed in terms of methodical and practical implications.     

Temporal patterns of schedule-induced drinking and pawgrooming in rats exposed to periodic food

Five rats were exposed to fixed-time food schedules, ranging from 30 to 480 sec. Three rats displayed a postfood pattern of schedule-induced drinking, with short latencies from food delivery to drinking at all interfood interval durations. In contrast, drinking for the other 2 subjects tended to occur at lower overall levels, and drinking bouts frequently began in the middle of the interfood interval, such that the latency from food delivery to drinking increased dramatically as the interfood interval increased. Observation of these 2 subjects revealed that another form of licking-pawgrooming-occurred reliably after food delivery and before drinking bouts. A between subject comparison of the 3 postfood drinkers and the 2 pawgroomers revealed that, in addition to a common topography (repetitive licking), pawgrooming and drinking were similar with respect to their temporal locus, relation to the interfood interval, and extinction baseline levels. These similarities suggest that drinking and pawgrooming are induced by a common mechanism. Cohen, Looney, Campagnoni, and Lawler’s (1985) two-state model of reinforcer-induced motivation provides a useful framework for the interpretation of these results.     

Real‐fiction versus historical reality: Rhetorical purification in “kent state”—the docudrama

This essay analyzes the ways in which Kent State, the made‐for‐TV docudrama, purified the image of William Knox Schroeder‐one of the four students killed on May 4, 1970, by Ohio National Guardsmen on the Kent State University campus. The author was a boyhood friend of Schroeder, his roommate at Kent State University at the time of his death, and an observer of many of the major events of the Kent State affair. This essay views the making of a docudrama as a complex problem to be solved and characterizes a docudramatist as a less‐than‐perfect decision maker. Also, this essay views Kent State as a real‐fiction through which the act of rhetorical purification was accomplished. The paper discusses the docudrama's efforts in this regard by analyzing important scenes in which inaccuracies are presented in order to achieve the purification of Schroeder's image.     

Japanese student activism in the 1970s

Student movements in Japan have, during the 1970s, tended to move from cooperation between various radical sects to bloody conflict among them, from participation by students generally to involvement by only a limited core of committed activists and from a struggle against the universityand society to one against society alone. The end of the war in Vietnam, the economic crisis, and other societal factors have contributed to these changes. The future of the student movement in Japan cannot be accurately predicted but it is unlikely that a powerful and politically effective movement, such as that of the 1960s, will re-emerge in the near future.
