The purpose of the study was to examine the differences among significant changes in the practice of individual teachers. Seventeen US teachers were interviewed about the most successful change in their teaching career. The differences in teacher change were based primarily on the source and impact of the change. The sources of change were divided into two categories: other-initiated or self-initiated. The level of impact was determined in three ways: by whether teachers described a new practice, a new direction, or a change in their beliefs. By organizing according to both the source and impact of the change, four types of change were identified: Response to School Initiatives, Professional Development Initiatives, Student-Centered Changes, and Self-Designed Changes. Self-Designed changes were further distinguished based on the time required for the change process. Implications for developing new strategies to foster teacher development are discussed.  相似文献

Objective

The aim of the study was to examine caregiver management strategies for child sexual abuse (CSA) when presented with hypothetical scenarios that vary in physical invasiveness.

Methods

One hundred fifty three caregivers were given 3 scenarios of CSA with 7 management strategies presented in the 21-item Taking Action Strategies (TAS) scale. Caregivers were asked to rate strategies according to their willingness to carry out each action with rating of 5 = greater likelihood of carrying out the action specified while a rating of 1 = a lower likelihood of carrying out that action. CSA scenarios included exposure to pornography/masturbation, fondling, and penetration while management strategies including fighting the accused, blaming the child, and outreaching to the authorities. Repeated measures ANOVA was used to compare mean TAS scores for the management strategies across CSA scenarios.

Results

The difference between TAS scores across the abuse scenarios was statistically significant (p < .001). Mean TAS scores reflected greater preference for taking action if the abusive act was perceived as more physically intrusive (exposure to pornography/masturbation-TAS 3.5, fondling-TAS 3.7, penetration-TAS 3.8). Caregivers reported being less willing to handle a disclosure of CSA without outreach (TAS 2.5 and 2.0 for fighting and blaming the child, respectively) and more willing to manage a disclosure with outreach to authorities (TAS 3.8, 4.5, and 4.7 for outreaching to Child Protective Services [CPS], to the child's healthcare provider and police, respectively). A predictor of caregiver outreach to authorities identified was the caregiver having past interactions with CPS.

Conclusion

Perception of the physical invasiveness of CSA and demographic factors can impact caregiver management strategies after a disclosure.

Practice implications

Results suggest that several factors influence caregiver management of sexual abuse. These factors warrant further study, as they are potential contributors to declining trends in CSA cases observed. Other implications include the need for educational efforts targeting caregivers. These interventions should focus on dispelling myths about the perceived physical invasiveness of CSA. These perceptions should not mitigate a caregiver's decision to involve the authorities in their management after a disclosure. Lastly, despite criticisms of the child protective systems, caregivers with past encounters with CPS view these related agencies as valuable resources.  相似文献

The present study characterized prototypical patterns of development in self-reported externalizing behavior, between 12 and 22 years of age, within a community sample of 452 genotyped individuals. A Caucasian subset (n = 378) was then examined to determine whether their probabilities of displaying discrete trajectories were differentially associated with CHRM2, a gene implicated in self-regulatory processes across a range of externalizing behaviors, and if affiliating with antisocial peers moderated these associations. Findings indicate that relative to a normative "lower risk" externalizing trajectory, likelihood of membership in two "higher risk" trajectories increased with each additional copy of the minor allelic variant at CHRM2, and that this association was exacerbated among those exposed to higher levels of peer group antisocial behavior.  相似文献

Background: A librarian consultation service was offered to 88 primary care clinicians during office hours. This included a streamlined evidence‐based process to answer questions in fewer than 20 min. This included a contact centre accessed through a Web‐based platform and using hand‐held devices and computers with Web access. Librarians were given technical training in evidence‐based medicine, including how to summarise evidence. Objectives: To describe the process and lessons learned from developing and operating a rapid response librarian consultation service for primary care clinicians. Methods: Evaluation included librarian interviews and a clinician exit satisfaction survey. Results: Clinicians were positive about its impact on their clinical practice and decision making. The project revealed some important ‘lessons learned’ in the clinical use of hand‐held devices, knowledge translation and training for clinicians and librarians. Conclusions: The Just‐in‐Time Librarian Consultation Service showed that it was possible to provide evidence‐based answers to clinical questions in 15 min or less. The project overcame a number of barriers using innovative solutions. There are many opportunities to build on this experience for future joint projects of librarians and healthcare providers.  相似文献

This study used accelerometer and self-report measures of overall sedentary time (ST) and screen time behaviours to examine their respective associations with adiposity among UK youth. Participants (Year groups 5, 8, and 10; n=292, 148 girls) wore the SenseWear Armband Mini accelerometer for eight days and completed the Youth Activity Profile, an online report tool designed to estimate physical activity and ST.Stature, body mass and waist circumference were measured to classify adiposity outcomes (overweight/obese and central obesity). One-way between groups ANOVA and adjusted linear, logistic and multinomial logistic regression analyses were conducted. There was a significant main effect of age on total ST across the whole week (F(2, 289)=41.64, p≤0.001). ST increased monotonically across Year 5 (581.09±107.81 min·dˉ¹), 8 (671.96±112.59 min·dˉ¹) and 10 (725.80±115.20 min·dˉ¹), and all pairwise comparisons were significant at p≤0.001. A steep age-related gradient to mobile phone use was present (p≤0.001). ST was positively associated with adiposity outcomes independent of moderate-to-vigorous intensity physical activity (MVPA; p≤0.001). Engaging in >3 hours of video gaming daily was positively associated with central obesity (OR=2.12, p≤0.05) but not after adjustment for MVPA. Results further demonstrate the importance of reducing overall ST to maintain healthy weight status among UK youth.  相似文献

We assessed young adolescent female soccer players' perceptions of their peer group experiences. Data were collected via interviews with 34 girls from two youth soccer teams (M age = 13.0 years). Following inductive discovery analysis, data were subjected to an interpretive theoretical analysis guided by a model of peer experiences (Rubin, Bukowski, & Parker, 2006). Five categories of peer experiences were identified across three levels of social complexity. At the interaction level players integrated new members into the team and learned to interact with different types of people. At the relationship level players learned about managing peer conflict. At the group level a structure of leadership emerged and players learned to work together. Findings demonstrated interfaces between peer interactions, relationships, and group processes while also simplifying some apparently complex systems that characterized peer experiences on the teams studied.  相似文献

Because traditional schools struggle to effectively understand, implement, and sustain digital learning initiatives, innovating with digital media in classrooms is a difficult endeavor. Practitioners need examples to better understand conditions necessary to move forward with digital media and learning (DML) in schools. This article provides examples and supports research proposing that context and culture matter when innovating in schools. Three classroom cases using Web 2.0, app development, and game design are discussed, offering educators a pathway to consider similar pedagogical and participatory approaches to foster learning. Classroom contexts, teachers' perspectives, district supports, technical requirements, and scalability are highlighted. The examples suggest innovative DML initiatives can flourish within schools when participants are mindful of context and when a participatory culture is supported (Jenkins, Clinton, Purushotma, Robison, & Weigel, 2006).  相似文献

The aim of this study was to examine the effects of sport goggles on visual target detection in female intercollegiate athletes. Participants were randomly divided into three groups that varied in goggle use (G) or no goggle use (NG) over a total of three 1-min trials during a visual target detection task. The NG-NG-NG group did not wear goggles for any of the trials, whereas the NG-G-NG group wore goggles for the second trial only, and the G-NG-G group wore goggles for the first and third trials. The task consisted of illuminated targets arranged in five concentric rings from central to peripheral visual angles. The effects of sport goggles on response time to detect targets were most evident in the peripheral rings. Those who did not wear sport goggles showed improved performance from the first to second trials. This improvement was impaired, however, in those who wore sport goggles. Moreover, there was a reversal of the performance improvements achieved without goggles in those who wore goggles on the third trial. Together, these findings suggest the sport goggles not only impaired the expected initial performance but also impaired visual target detection after performance improvements were seen. These findings suggest sport goggles may impair detection of peripheral visual stimuli in athletes.  相似文献
