Bullying in schools has been identified as a serious and complex worldwide problem associated with negative short- and long-term effects on children’s psychosocial adjustment (Smith 1999; Ttofi and Farrington, Aggressive Behav 34(4):352–368, 2008). Entering kindergarten is a crucial developmental step in many children’s lives mainly because it is within this context where they participate, for the first time, as members in a stable peer group and well-organized team activities. Consequently, preschool may be the first context beyond the home environment where children’s difficulties in social interactions with peers can be primarily detected and assessed by adults and professionals. This paper reviews recent empirical evidence over the nature and different aspects of bullying among preschool children. Recent findings concerning the development of preschool bullying and its prevalence, family and genetic factors, gender and age differences, participant and peripheral roles, school context, methodological issues, and prevention policies are reviewed while directions for future research are addressed.  相似文献

Background: University physics students were engaged in open-ended thermodynamics laboratory activities with a focus on understanding a chosen phenomenon or the principle of laboratory apparatus, such as thermal radiation and a heat pump. Students had access to handheld infrared (IR) cameras for their investigations.

Purpose: The purpose of the research was to explore students’ interactions with reformed thermodynamics laboratory activities. It was guided by the research question: How do university physics students make use of IR cameras in open-ended investigation of thermal radiation as a phenomenon?

Sample: The study was conducted with a class of first-year university physics students in Sweden. The interaction with the activities of four of the students was selected for analysis. The four students are males.

Design and methods: We used a qualitative, interpretive approach to the study of students’ interaction. The primary means of data collection was video recording of students’ work with the laboratory activities and their subsequent presentations. The analysis focused on how IR cameras helped students notice phenomena relating to thermal radiation, with comparison to previous research on students’ conceptions of thermal radiation.

Results: When using the IR camera, students attended to the reflection of thermal radiation on shiny surfaces, such as polished metals, windows or a whiteboard and emissive properties of surfaces of different types. In this way, they went beyond using the technology as a temperature probe. Students were able to discuss merits and shortcomings of IR cameras in comparison with digital thermometers.

Conclusions: With the help of IR cameras, university physics students attend to thermal phenomena that would otherwise easily go unnoticed.  相似文献

The paper examines the views of students regarding the extent of their participation in the management of their university and their satisfaction with the degree of this participation. After an examination of the literature on student participation in university governance, the author presents the results of a survey based on data collected from 135 students of the University of Cyprus in 2002. According to the findings, respondents believed that their involvement in the management of their institution was very limited. This applied to both high and low levels of decision making, even though respondents recognised that their input was greater in less important decisions. The perceived limited involvement resulted in feelings of frustration and dissatisfaction among students, with the majority of respondents demanding a higher level of participation for all three decision making situations considered in the study. The paper discusses the implications of the findings for the practice of distributed leadership at contemporary universities, with emphasis on the need to abandon outdated leadership models. Specifically, it proposes measures for increasing student participation in university governance in the framework of a distributed leadership approach designed to empower the key stakeholders of higher education.  相似文献

This study investigates continuing professional development (CPD) of vocational teachers, with a focus on recurrent participation. Vocational teachers need to be competent as teachers and in relation to their vocational teaching subject. Reformation of Swedish vocational education in order to strengthen the working-life connection imposes demands on teachers to have up-to-date knowledge about the vocations related to their vocational subjects. To support the reform, vocational teachers have been offered to participate in a new national CPD initiative targeting their vocational competence. The study concerns participation in this initiative. Drawing on a socio-cultural perspective, vocational teachers’ CPD implies boundary-crossing between school and working-life. Theory concerning adults’ participation in education is considered relevant to understand conditions for such boundary-crossing, and learning, among vocational teachers. The article specifically investigates patterns in vocational teachers’ recurrent participation, which is expected to clarify the factors influencing further participation in professional development. The strongest predictor of recurrent participation, when adjusting for the influence of other factors, is the type of municipality that the teacher comes from, with low populated municipalities having the lowest likelihood of participation. Furthermore, recurrent participation is more likely by participating teachers from adult education or from privately owned schools, and by male teachers.  相似文献

This study analysis the relationship between perceptions of the justice of teacher’ behaviour and (a) the legitimation of school authority and (b) the legitimation of institutional authorities outside school. 448 adolescent students participated in the study. In questionnaire participants were asked about (a) perceptions of the justice of teachers’ behaviour; (b) evaluation of the school experience; and (c) evaluation of institutional authorities. Results show that the evaluation of the justice of teacher behaviour, in particular relational and procedural justice, have an impact on the legitimation of the authority of teachers and on the evaluation of institutional authorities outside school. Results also show that the legitimacy granted to teachers is a mediator variable between perceptions of justice in school and evaluation of authorities outside school. These results are discussed in the context of the studies on the relationship between school experience and adolescents attitudes towards authorities, and in the framework of the “Relational Model of Authority” and of the “Group Value Model”.  相似文献

The AGIRE project, under the Edulab concept, aims to promote the adoption of innovative teaching practices. This paper reports the support strategies used to evaluate the teacher practices at the end of a teacher training course (TTC) and analyse its impact on teacher technology integration, using a design-based methodology. Teachers’ initial perception was gathered using an online questionnaire comprising ICT personal and professional competencies. The questionnaire results and the classroom observations showed that the majority of teachers were at the level of ICT adoption, before attending the TTC, reaching the adaptation level of integration of ICT, after the TTC. A variety of teaching strategies (flipped classroom, collaborative work, …) and technologies (interactive white boards, tablets, videos, …) were explored. The results sustain the thesis that, with proper support, ICT can be integrated in educational contexts in an innovative way and contribute to the development of teachers’ digital literacy.  相似文献
