The study reported here concerns 4 years of collaboration between secondary school teachers and academic researchers, constituting
an emerging community of inquiry into mathematics teaching. In the article, the process of the forming of this community is
discussed, focusing on the reflective activity developed by its members as well as the tensions and conflicts that emerged
in the shaping of an inquiry identity by them. Furthermore, shifts in the mode of participation in the community and thus
learning gains of all members are identified, with the teachers gradually developing an awareness of teaching practice in
general, and the researchers becoming progressively acquainted with the reflexive relationship between inquiring into teaching
practice and teachers’ professional development. 相似文献

Doping use is an ongoing problem in contemporary sports. Despite efforts to detect and control doping, research on its etiology is limited, especially among elite-level athletes. The present study used an integrated social cognition model to examine the predictors of doping intentions. Structured anonymous questionnaires were completed by 1075 Greek adult elite-level athletes (M age = 25 years, SD = 5.89, 36.1% females) from both team and individual sports. Multiple regression and mediation analyses showed that attitudes, normative beliefs, situational temptation, and behavioral control significantly predicted doping intentions. A normative process was identified whereby situational temptation mediated the effects of normative beliefs on intentions. The findings provide the basis for future social cognition research in doping use, and set the framework for the development of evidence-based preventive interventions. 相似文献

AbstractThe present study set out to assess the impact of attributional beliefs about success on the susceptibility for doping use in adolescent athletes. The sample consisted of 309 adolescent athletes participating in both team and individual sports. Participants completed a battery of questionnaires including Beliefs about the Causes of Success in Sport Questionnaire (BACSSQ), current and past doping use, and measures of attitudes, norms, situational temptation and social desirability. Variance reduction rate analysis revealed that social desirability did not act as a confounder in the relationship between doping susceptibility and its predictors. With regard to beliefs about the causes of success dimensions, only deception emerged as a significant predictor of doping use susceptibility over and above the effects of well-established social–cognitive predictors of doping intentions and use. These findings imply that beliefs about the causes of success in youth sports may comprise another dimension of risk factors for doping susceptibility and use. 相似文献

A new class of antenna array lattices is examined and classified by using the formalism of the space point groups. The space symmetries of the current excitations and their resulting patterns are investigated. A new procedure for designing orthogonal antenna field patterns is developed. 相似文献
