This study investigated teachers’ professional identity development. Using Dialogical Self Theory and a socio-cultural semiotic mediational perspective, we focused on pre- and in-service teachers’ communication of professional role expectations and related feelings when solving pedagogical dilemmas to reveal aspects of their professional identity construction. Data were collected from 102 pre- and 90 in-service teachers by asking them to solve seven pedagogical dilemmas. We report: (1) how pre- and in-service teachers solved pedagogical dilemmas in terms of communicating professional role expectations and related feelings; (2) how pre- and in-service teachers differed in the feelings they reported and the solutions they gave when solving pedagogical dilemmas; and (3) how the communication of professional role expectations and feelings was related to pre- and in-service teachers’ work experience. Finally, we discuss the implications of our study for initial and continuing teacher education programmes. 相似文献

Polyethylene-nanocomposites with CaCO3-weight fractions from 0 to 15 wt.% were prepared by in-situ polymeriza- tion with Me2Si(Ind)2ZrCl2/MAO metallocene catalysts. A high activity especially in the presence of TIBA was observed. The morphology was investigated by using raster electron microscopy (REM) showing that the CaCO3-nanoparticles are uniformly distributed. The melting temperatures and the crystallization temperatures are not much influenced by increasing filler content. 相似文献

The aim of this study was to contribute to the understanding of the effectiveness of formative assessment interventions by analysing how the quality of programme delivery affects students’ mathematics achievement and interest. Teachers (n = 17) implemented formative assessment in their ninth-grade mathematics classes and provided their students (n = 426) with written process-oriented feedback. Four feedback characteristics (number of feedback comments, specificity, feedback at self level, social reference norm) and two types of embedment of feedback in the instructional context (focus on feedback utilisation, focus on performance evaluation) were evaluated. Multilevel regression analyses revealed no significant effects of feedback characteristics on interest but negative effects of number of feedback comments and specificity on achievement in mathematics. Positive effects on mathematics achievement and interest were found when feedback was embedded in instruction and had emphasis on feedback utilisation. Students’ interest also was affected positively when performance evaluation was stressed. 相似文献

Teaching sensitive and controversial issues (SCIs) is of growing interest in contemporary, increasingly heterogeneous societies. In democracies, different groups and institutions expect their values and worldviews to be conveyed at school. On one hand, there is the expectation that SCIs should be treated neutrally. On the other hand, there are disputes over what exactly should be seen as controversial in the first place. Research on SCIs in social studies and civics has distinguished many pressures that teachers face from the very local – the community and the parents of their pupils – to curriculum policies and issues in broader social and political fields. Research on history teaching has studied ways of dealing with divergences between collective memories, and academic and lay ways of dealing with the past. The present study combines insights from both research strands. Based on interviews with Estonian and Latvian history teachers, I discern teacher positions on, and strategies for, teaching SCIs: hiding or avoiding; finding common ground or smoothing edges; just doing the job; enhancing heterogeneity and leaving the truth open. This study illustrates the complexity and multilayered nature of the challenges that shape teachers’ choices and ways of coping with the various demands they perceive. Dealing with SCIs is shaped by tensions between sociopolitical, academic and educational factors and identities. 相似文献

Procrastination, putting off until tomorrow what should have been done today, is a self-regulation failure that is widespread among students. Although plenty of research has emerged regarding academic procrastination, hardly any research endeavor regarding procrastination in distance university settings exists. This lack of research is even more astonishing when considering that the demands on self-regulation are higher in distance education settings than in traditional university settings. The present (questionnaire) study was intended to shed light on procrastination in an actual distance university setting by exploring its relationship to grades, learning strategies (e.g., cognitive, meta-cognitive strategies), and life satisfaction in students from a distance university in comparison to students from a traditional university. 相似文献

Recent highly publicized cases of scientific misconduct have raised concerns about its consequences for academic careers. Previous and anecdotal evidence suggests that these reach far beyond the fraudulent scientist and (his or) her career, affecting coauthors and institutions. Here we show that the negative effects of scientific misconduct spill over to uninvolved prior collaborators: compared to a control group, prior collaborators of misconducting scientists, who have no connection to the misconduct case, are cited 8–9% less often afterwards. We suggest that the mechanism underlying this phenomenon is stigmatization by mere association. The result suggests that scientific misconduct generates large indirect costs in the form of mistrust towards a wider range of research findings than was previously assumed. The far-reaching fallout of misconduct implies that potential whistleblowers might be disinclined to make their concerns public in order to protect their own reputation and career. 相似文献
