Teacher discipline strategies are well documented when it comes to its effects on students and the working climate in the classroom. Although it is commonly acknowledged that for student teachers classroom management is a major concern, student teachers’ use of discipline strategies is largely unknown. In this paper, we examine student teachers’ beliefs in relation to their discipline strategies. Three clusters of discipline strategies are distinguished: sensitive, directive and aggressive discipline strategies. Beliefs that were taken into account are self-images on control and affiliation, control orientation and anticipated student responses on control and affiliation. All participants were student teachers of a one-year teacher education programme for secondary education in the Netherlands. Student questionnaires were used to measure discipline strategies (n?=?2506). Student teachers’ (n?=?104) self-images, control orientation and anticipated student responses were measured with student teacher questionnaires. Results of the multiple regression analyses showed that student teachers’ sensitive and directive discipline strategies are explained best by self-images on control; aggressive discipline strategies are explained best by self-images on affiliation and by control orientation. Apart from the possible academic interest in these particular findings, results are believed to be useful in a practical sense, in particular for teacher education programmes. 相似文献

The present study focuses on how student-teachers attempt to elicit the practical knowledge of the mentor teachers who supervise their practical training. Having access to the practical knowledge of their mentors means, among other things, that student-teachers have access to the cognitions underlying teaching that can help them to understand their mentors' teaching style, advice, and feedback. The analysis of 29 interviews with student-teachers revealed three self-initiated activities for this access: (1) observing a mentor's lesson; (2) asking specific questions about lessons observed; and (3) discussing the student's lesson or teaching and education in general. Not all the activities mentioned by the student-teachers elicited what is called 'practical knowledge' in the literature. As practical knowledge is an important element of the learning-to-teach process, it was concluded that the stimulation of activities aimed at exploring this knowledge could make a valuable contribution to teacher education. The instruments used in the research on teacher knowledge and beliefs could be helpful for attaining this objective. Implications of this research for teacher education and suggestions for further research are presented. 相似文献

The Akt-mTOR-p70S6k-4E-BP1 signaling pathway is a well-considered regulator of protein synthesis in the context of strength training. This process is essential for exercise-induced skeletal muscle growth. The objective of this review article was to analyze the design of acute resistance training protocols and evaluate the possible impact of different loading conditions on the activation of growth-related signaling cascades in human skeletal muscle. In all, 12 human studies were included in this review. The training intensity in the studies varied between 30% 1RM (one repetition maximum) and maximal load. The signaling proteins were measured in a time range between immediately and 24?h after training.The phosphorylation of all signaling proteins increased to different levels after resistance training, tending to baseline more than 6?h post training. In particular, the hypertrophic associated p70S6k showed the highest phosphorylation acutely after the load and decreased consistently after 6?h. Training intensity and volume seemed to have an influence on the extent of protein phosphorylation, which, however, was not systematic or consistent. An obvious training methodological consequence (load and volume) for hypertrophic resistance training regime could not be devised. Further research is required to systematically vary training parameters to determine the influence of a certain stress zone on the signaling activation. Future research should aim to identify the ideal level of training intensity necessary to achieve the greatest possible extent of intramuscular anabolic signaling through intense activation of the signaling cascade to induce growth in human skeletal muscle. 相似文献

Experimental skills should be acquired by learners at school and university alike. To promote experimental skills, various approaches exist within a spectrum between implicit and explicit instruction. Regarding these instructional approaches, numerous findings are available which predominantly relate to pupils. It is an open question whether it is better to instruct experimental skills explicitly or implicitly in university courses. And if experimental skills are fostered explicitly, what about the content-related skills? Especially in teaching programmes with both experiment-related and content-related objectives, it is questionable whether content-related objectives are achieved to a lesser degree via explicit instruction of experimental skills. Both questions are addressed in this paper. We present an intervention study involving 144 students. All students carry out the same experiments. The intervention groups differ merely in the degree of explicit instruction. Learning gains in experimental and content-related skills are assessed in a pre-/post-test design. The results show that the type of instruction does not significantly influence the acquisition of experimental and content-related skills in this target group. But by trend, the expected differences in learning gains can be observed. This leads to new research perspectives and implications for teaching which are discussed. 相似文献

Objectives
To determine the prevalence and characteristics of reports of emotional maltreatment (EMT) in Canada, as well as changes in these reports between 1998 and 2003.Methods
This study is based on a secondary analysis of data collected in the first and second Canadian Incidence Study. Emotional maltreatment (excluding exposure to intimate partner violence) investigations were categorized into six groups: emotional abuse, emotional neglect, and other maltreatment as the only investigated form of maltreatment, and these same three groups were examined when they co-occurred with another form of maltreatment.Results
Both the rate of emotional-abuse-only investigations and emotional-neglect-only investigations increased almost threefold from 1998 to 2003. Substantiated emotional neglect investigations had the highest rate of transfer to ongoing services. Half of the investigations involving single forms of emotional maltreatment occurred for six months or more. Finally, emotional neglect cases (in single form and when it co-occurs with another form of maltreatment) were more likely to be associated with emotional harm and longer duration of maltreatment.Conclusions
In 2003, EMT represented a significant increasing form of maltreatment and is detected nearly twice as often in situations in which abuse or neglect are also reported. Reports of emotional abuse are two and a half times more frequent than reports of emotional neglect. Nevertheless, lack of emotional engagement may also be difficult to identify, since an omission is more difficult to detect. Reports of EMT often reveal situations of chronic victimization that have been the subject of previous reports and are associated with greater emotional impact. 相似文献46.

ABSTRACTThe process of global modernization has reached a new phase. In many parts of the world, societies have become so complex that the logic that characterized first modernity no longer works. Simultaneously, societies are confronted by huge and complex side effects of modern rationality, such as climate change, migration influx, global inequality, and waning confidence in the nation-state. Consequently, we are entering an age of reflexive modernity. In our view, this new social configuration has important consequences for what Christian higher education can contribute to the education of new professionals. In this article, we will reflect on the way in which three collaborating Christian universities of applied sciences in the Netherlands are searching for answers on the challenges of our time. We propose, firstly, that they should give more attention to the relational formation of professionals than before. These professionals have to bridge the gap between professional and client, system and lifeworld, professionalism and personality, and professionalism and spirituality. Secondly, the professionals trained at Christian institutions of higher education should develop a strong professional ethos that allows them to act swiftly and efficiently in complex situations. In order to develop such an ethos, moral traditions are indispensable. Although the new social configuration does not seem to be very favorable for Christian higher education, on closer inspection it brings new opportunities. 相似文献

An understanding of the key characteristics and implicit competencies underlying online teaching is essential to distance education institutions that embark on the assertive use of technology in their tuition development and delivery. The Virtual Teaching Dispositions Scale (VTDS) assists in investigating professional teaching dispositions associated with effective online instruction. It was initially validated among academic staff members at a residential university in the United States of America (USA). Strong support was found for the construct's cognitive, pedagogical and social presence that served as the conceptual foundation for developing the scale. The aim of this study was to validate the VTDS among academic staff members of an open distance learning (ODL) institution and to make suggestions for improving online teaching in this environment. This study highlights the need for interventions aimed at enhancing academic staff members’ experienced level of virtual/technological presence. 相似文献

Relating students' reasoning to the history of science: The case of chemical equilibrium 总被引：1，自引：0，他引：1
In this study, the reasoning of students, who are introduced to the concept of chemical equilibrium, was related to the historical
development of this concept. In the first stage of the study, remarkable similarities were observed between students' reasoning
on the issue of incomplete chemical conversions and the reasoning of 19th-century scientists, especially when molecular notions
were included. In the next stage of the study, some authentic problems and questions, that were essential in the historical
development of chemical equilibrium, were presented to students. It appeared that they recognised the significance of these
problems and questions. Moreover, most students were eager to find explanations. Students, reasoning in molecular terms, would
sometimes explain these problems in terms similar to historical explanations. Other students, however, suggested explanations
in non-molecular terms, which, although chemically valid, did not appear to have historical antecedents. It was concluded
that the study of authentic historical sources may inspire the design of effective teaching activities. 相似文献
