A group randomized controlled trial tested the efficacy of the Friendly Schools program to reduce student bullying behaviour. This socio‐ecological intervention targeted the whole school, classroom, family, and individual students to reduce bullying behaviour. Self‐report data were collected in 29 schools over three years from a cohort of 1968 eight to nine‐year‐olds. Surveys measured frequency of being bullied, bullying others, telling if bullied and observing bullying. Results indicate that intervention students were significantly less likely to observe bullying at 12, 24 and 36 months and be bullied after 12 and 36 months, and significantly more likely to tell if bullied after 12 months than comparison students. No differences were found for self‐reported perpetration of bullying. The findings suggest whole‐of‐school programs that engage students in their different social contexts appear to reduce their experiences of being bullied and increase their likelihood of telling someone if they are bullied.  相似文献

In this study, we investigated the effects of two hydrotherapy interventions on match running performance and perceptual measures of fatigue and recovery during a 4-day soccer tournament. Twenty male junior soccer players were assigned to one of two treatment groups and undertook either cold-water immersion (5 × 1 min at 10 °C) or thermoneutral water immersion (5 × 1 min at 34 °C) after each match. High-intensity running distance (>15 km · h?1) and total distance covered, time spent in low (<80% maximum heart rate), moderate (80-90% maximum heart rate), and high (>90% maximum heart rate) heart rate zones, and rating of perceived exertion (RPE) were recorded for each match. Perceptions of general fatigue and leg soreness were recorded approximately 22 h after each match. There were decreases in both groups across the 4-day tournament for high-intensity running distance (P = 0.006, Cohen's d = 0.63), total distance run (P < 0.001, d = 0.90), time in high heart rate zone (P = 0.003, d = 0.90), and match RPE (P = 0.012, d = 0.52). Cold-water immersion was more effective than thermoneutral immersion for reducing the perception of leg soreness (P = 0.004, d = -0.92) and general fatigue (P = 0.007, d = -0.91), ameliorating the decrement in total distance run (P = 0.001, d = 0.55), and maintaining time in the moderate heart rate zone (P = 0.01, d = 1.06). In conclusion, cold-water immersion mediates the perceptions of fatigue and recovery and enhances the restoration of some match-related performance measures during a 4-day tournament.  相似文献

To examine the development of look duration as a function of age and stimulus type, 14- to 52-week-old infants were shown static and dynamic versions of faces, Sesame Street material, and achromatic patterns for 20 s of accumulated looking. Heart rate was recorded during looking and parsed into stimulus orienting, sustained attention, and attention termination phases. Infants' peak look durations indicated that prior to 26 weeks there was a linear decrease with age for all stimuli. Older infants' look durations continued to decline for patterns but increased for Sesame Street and faces. Measures of heart rate change during sustained attention and the proportion of time spent in each phase of attention confirmed infants' greater engagement with the more complex stimuli.  相似文献

Teaching has been described as an emerging community of practice. Within such professional communities, the processes of reflection and collaborative dialogue, or critical transformative dialogue, are central to the maintenance and improvement of professional practice for individuals, and the field. This paper reports on the challenges experienced by a group of first-year pre-service teachers engaging in a process of reflection and critique with peers, as they participated in a program focused on the development of core practices of teaching. These pre-service teachers' responses indicated their growing understanding of the importance of engaging in ongoing critical dialogue, as part of the “unnatural” aspects of teaching. The paper concludes with a reflection on the value of feedback from the earliest stages of professional learning.  相似文献

In this paper we discuss the notion of the digital divide and link it with recent policy designed to promote social inclusion in a project that addressed both issues. Families in low socio economic areas of Australia were given computers and Internet access as part of a project that had as its primary aim to support the participation of disadvantaged families in digital activities at home and in schools. The authors collected data over a period of 3 years that included, pre and post surveys with parents and students, interviews with program facilitators, and focus groups with parents. This paper focuses on selected themes that emerged from the interview and focus group data with the parents and explores the ways in which they perceived having the computer had impacted on their lives and those of their school aged children. This data (surveys, interviews and focus groups) reveals that all family members felt that the ownership of a computer enabled them to feel more confident about their active participation in everyday educational, social and community activities. Parents, teachers and students also reported that owning a computer was important to their lives yet they were not naïve to the fact that they still had a lot to learn in terms of using all the options available to them on the computer. Students noted the increased ease with which they could complete school work and communicate with friends in online contexts and outlined some of the ways in which they used the computer for leisure activities. Parents highlighted the increase in their own digital skill levels and described the ways in which their lives had benefitted from having a computer in the home. Problems associated with connectivity at the beginning of the project, the quality of the machines and inadequate initial training were listed as drawbacks to greater participation. The project represents one attempt to address the digital divide and illustrates how going beyond the dichotomy of a ‘haves’ v ‘have nots’ view of the digital divide is necessary if we want to promote social inclusion.  相似文献

ABSTRACT

Undergraduate research experience has been shown to enhance student learning and improve persistence in science, technology, engineering, and mathematics (STEM). Researchers studying undergraduate research experiences have largely focused on student outcomes and have seldom investigated the outcomes of graduate and postdoctoral mentors. Here, we report a non-credit, year-long mentor professional development program designed for graduate students, postdoctoral scholars, and research staff in STEM. Mentors attended a series of six interactive and discussion-based workshops and mentored first-year undergraduate students in independent summer research projects. We report evaluation findings for three mentor cohorts using a combination of qualitative analysis of mentoring philosophies and quantitative assessment of pre- and post-surveys about mentoring objectives and skills. Results indicate that mentors gained self-efficacy in some objectives and skills. However, many other objectives and skills remained unchanged. We explore possible explanations for the lack of more broad-scale gains across survey items and present ideas for program improvement.  相似文献

Excessive course attrition is costly to both the student and the institution. While most institutions have systems to quantify and report the numbers, far less attention is typically paid to each student’s reason(s) for withdrawal. In this case study, text analytics was used to analyze a large set of open-ended written comments in which students explained their reason(s) for course withdrawal in their own words. The text for all comments was extracted verbatim from the course withdrawals database of Florida State College at Jacksonville, a large, diverse, multicampus institution located in northeast Florida. An initial set of 616 comment records from the beginning of the fall 2010 term was used to develop a preliminary text analytics model. This model revealed 11 major category nodes and successfully classified 96.1% of all withdrawal records into one or more categories. The model was retained and further tested using a second set of 679 records from the spring 2011 term and found to successfully classify 98.7% of the spring records. At the broadest level, withdrawal explanations were found to include both academic and nonacademic student rationales. Leading academic rationales involve course scheduling adjustments, delivery method preference changes (e.g., classroom vs. online), and faculty related reasons. Leading nonacademic rationales include personal issues especially involving job/work, family, financial, and health matters. The limitations of the study along with implications for practice, administrative decision making, and future directions for the expanded use of text analytics in institutional research are discussed.  相似文献
