Within the past decade, the achievement goal approach has begun to be used to study teacher achievement motivation. In recent research with students, a 3 × 2 model of achievement goals has been proffered that separates mastery-based goals in terms of a task/self distinction. The purpose of the present study was to extend this 3 × 2 model to teachers in order to provide important insights into teachers’ individual differences. We devised items for the questionnaire and showed that data obtained with the 3 × 2 Achievement Goal Questionnaire for Teachers fit the 3 × 2 model (in absolute terms and relative to 10 alternative models) and that each goal of the model exhibited good internal consistency. In addition, we linked the 3 × 2 goals to other key constructs relevant to achievement goals, namely, implicit theories of ability, instructional practices and intrinsic interest.  相似文献

While the call for interdisciplinary studies has been loud and clear over the last decade or so, the number of interdisciplinary publications in sport sciences is rather limited. One of the reasons for this scarcity is the complexity of the research process itself. Still, the combination and integration of information from different scientific disciplines seems to be important to better explain how elite performance comes about. In this article, we focus on this issue and discuss the advantages of interdisciplinary research for understanding how elite athletes are able to achieve such high-proficiency levels. The first section provides an overview of the studies that investigated elite performance in sports. In the second section, we focus on the issue of interdisciplinarity and illustrate how the ecological–dynamical approach and the concept of dimensional reduction can be used to explain how elite performers cope with the complex nature of sport skills. In the last section, we present a research outline and some practical considerations that can be helpful for researchers who aim to study sport skills from an interdisciplinary perspective.  相似文献

This article deals with the demands that plagiarism places on academic communities, and with the resources staff possess in dealing with these demands. It is suggested that plagiarism ought to be placed in the context of network of intertwining communities (scholarly, pedagogical and administrative), to which participants are engaged to a different extent. The relationship to the ethical issue of plagiarism is related to the subject’s engagement in these communities. The article examines the way teachers deal with plagiarism from the point of view of work engagement and work-related wellbeing. In particular, we analyse job demands created by episodes of dealing with plagiarism as well as job resources teachers possess that aid them in coping with these demands. We used thematic analysis of semi-structured interviews of teachers in two universities. Our results show that the demands fall on five thematic categories: 1. rupture in the personal pedagogical relationship, 2. challenge on the supervisory “gatekeeping” responsibility; 3. a breach of the “everyday normality”; 4. ambivalence in explaining plagiarism and 5. the strain of performing the act of accusation. A key job demand in dealing with plagiarism is that teachers must balance both rule-ethical and care-ethical orientations in their reactions and actions. The resources teachers draw upon when dealing with these demands are: 1) dialogue and reflection in collegial dialogue 2) support from superiors and administration 3) shared protocols, procedures and plagiarism detection software. Our analysis shows that there are various demands that make dealing with plagiarism a strenuous task, but university environments also provide teachers with resources to cope with them.  相似文献

Until now studies comparing fathers and mothers have mostly been realized in dyadic situations, father-infant versus mother-infant. The aim of the present paper was to bring to the core similarities and differences, between fathers and mothers, in terms of performance (N=42 families) in a triadic context. Father, mother and baby, seated in a triangular formation were invited to play as usual: first, one parent played with the infant and the other was participant-observer, and then they reversed their roles. Globally, no differences were observed between fathers and mothers in terms of being available, keeping their assigned roles, sharing a common focus of interest and co-creating games with their three month old infant. However a difference emerged when the order in which parents began as active parent versus third party parent was taken into account. Mothers who played first were better active partners than fathers, for keeping roles, sharing focus and co-creating games; and fathers who were first third party parent were better than third party mothers for sharing a common focus.  相似文献

Children struggle to stop inappropriate behaviors. What interventions improve inhibitory control, for whom, and why? Prior work suggested that practice proactively monitoring for relevant signals improved children’s inhibitory control more than practice with motoric stopping. However, these processes were not clearly dissociated. This study tested 162 seven- to nine-year-old children (89 female, 72 male, 1 unreported; 82% White) on the stop-signal task, following monitoring or stopping-focused practice. Both methods improved inhibitory control, supported generalization, and interacted ( = .20–.73). Practice approaches differentially impacted variability ( = .01–.09). Only monitoring benefits showed signs of depending upon proactive control ( = .02). These findings highlight unique contributions of attentional and stopping processes to inhibitory control, suggesting possibilities for tailored interventions.  相似文献

There is great interest in highly sensitive separation methods capable of quickly isolating a particular cell type within a single manipulation step prior to their analysis. We present a cell sorting device based on the opposition of dielectrophoretic forces that discriminates between cell types according to their dielectric properties, such as the membrane permittivity and the cytoplasm conductivity. The forces are generated by an array of electrodes located in both sidewalls of a main flow channel. Cells with different dielectric responses perceive different force magnitudes and are, therefore, continuously focused to different equilibrium positions in the flow channel, thus avoiding the need of a specific cell labeling as discriminating factor. We relate the cells’ dielectric response to their output position in the downstream channel. Using this microfluidic platform that integrates a method of continuous-flow cell separation based on multiple frequency dielectrophoresis, we succeeded in sorting viable from nonviable yeast with nearly 100% purity. The method also allowed to increase the infection rate of a cell culture up to 50% of parasitemia percentage, which facilitates the study of the parasite cycle. Finally, we prove the versatility of our device by synchronizing a yeast cell culture at a particular phase of the cell cycle avoiding the use of metabolic agents interfering with the cells’ physiology.  相似文献
