Six hundred and forty high-school students (Grades 7–12) from a large central government school in South India participated in this exploratory study of online bullying (cyberbullying) in India. Participants responded to the Survey on Social Use of Information and Communications Technology (SSUICT; Bhat and Ragan 2013). Findings indicated that approximately half the participants experienced online bullying in one or more roles described by Bhat et al. Education about Asia, 2(18), 36–39, (2013), with these being: initiating online bully, secondary online bully, bystander, or target of online bullying. Overall, engagement in online bullying tended to increase with grade level, and participation in the role of secondary online bully was the highest of the four roles for Grades 8–12. Male participants reported higher engagement in all four roles than female participants, and this difference was significant for the roles of initiating online bully, secondary online bully, and target of online bullying. Significant correlations were found between the four roles of online bullying. Recommendations for addressing the issue of online bullying in the Indian context are provided, along with limitations of the study and suggestions for future research.  相似文献

Research Findings: This article examines whether time spent in free choice and teacher-directed activity settings within preschool was associated with indicators of school readiness and the extent to which children’s learning was associated with the quality of teachers’ behavior within these settings. Participants were 325 preschool teachers and 1,407 children from low-income backgrounds. Teacher–child interactions were measured in multiple cycles across 1 day of classroom observation within teacher-organized free choice and teacher-directed activity settings. The overall proportion of class time spent in free choice was positively related to children’s average gains in inhibitory control, whereas class time spent in teacher-directed activities predicted gains in language development and early literacy skills. And more effective teacher–child interactions within the free choice setting were significantly related to children’s average gains in language development and early literacy skills. Practice or Policy: Findings confirm that both free choice and teacher-directed settings in early education classrooms can be assets for children’s learning; however, the value of time in child-managed activities is partially dependent on teachers’ behavior with children.  相似文献

School-based management (SBM) is a standard feature of many current reforms. While previous research found that poorly designed and poorly implemented SBM had few positive effects, recent research suggests that SBM can improve instructional programs and produce higher levels of student learning. This article synthesizes research findings from major studies of SBM to identify the core elements of a successful SBM strategy. By comparing schools that successfully used SBM with schools that struggled to implement SBM, we generate 8 elements of schooling that were associated with successful SBM. In brief, these elements address vision, decision-making authority, power, knowledge and skills, information, rewards, leadership, and resources.  相似文献

Abstract

The present experiment evaluated the effects of a 27-day sit up exercise training program on adipose cell size and adiposity. Fat biopsies were taken from the abdomen, subscapular, and gluteal sites by needle aspiration in 13 experimental and 6 control male subjects before and after a five days/week progressive training regimen. Day 1 consisted of 10 bouts of 10-sec exercise, 7 sit ups/bout, with 10-sec rest intervals; on day 27, 14 bouts of 30-sec exercise were performed, 24 sit ups/bout with 10-sec rest intervals. The total number of sit ups done was 5004. Fat cells were isolated using collagenase and photographed to determine cell diameter. Repeated measures ANOVA revealed significant decreases in cell diameter at the three biopsy sites (p<.01), but no significant differences in the rate of change (pre to post) in cell diameter between sites for the experimental and control groups (p>.05). Body weight, total body fat (underwater weighing), and fatfolds and girths remained unaltered. The results demonstrate that (1) the conventional sit up exercise does not preferentially reduce adipose cell size or subcutaneous fat thickness in the abdominal region to a greater extent compared to other adipose sites, and (2) significant changes in fat cell size may occur in the absence of changes in fatfolds, girths or total body composition.  相似文献

The prevalence of charter management organizations (CMOs)—networks of charter schools overseen by a home office—has exploded in recent years but there is a paucity of research into how CMOs approach growth and the factors that influence their growth plans. In this qualitative study, we examine how a set of 25 older, more established CMOs approached growth. Findings suggest that strategies for scale-up varied depending on the external policy environment and the internal organizational capacity of the CMO. In addition, CMOs approached growth from one of three styles: premeditated, opportunistic, or organic. Finally, longitudinal data reveal that CMOs often struggled to meet their growth targets; fewer than half of the sample CMOs met or were on track to meet their projected scale-up targets. From these findings emerged a key source of tension: On one hand, CMOs are facing pressure from policymakers and foundations to grow and expand rapidly. On the other hand, scaling-up too quickly or in ways that fall outside of the CMO’s mission can lead to serious consequences for the organization, its schools, and students. Our research aims to contribute to this debate by demonstrating that “one size does not fit all” for CMO scale-up, a lesson important for policymakers, educators, and researchers alike.  相似文献

In Australia, graduates of Master of Public Health (MPH) programmes are expected to achieve a set of core competencies, including a subset that is specifically related to Indigenous health. This paper reports on the methods utilised in a project which was designed using action research to strengthen Indigenous public health curricula within MPH programmes at Australian universities. This aim is achieved through the use of three interlinked ‘action–reflection’ cycles, involving individual Indigenous public health academics who, through their membership in a scholarly network, have undertaken a series of curriculum reviews, which have in turn influenced organisational change in universities. The project results demonstrated how action research can successfully strengthen Indigenous public health curricula.  相似文献
