Teachers’ perceptions of their most significant change: source,impact, and process     

John E. Henning  Linda J. Rice  Danielle E. Dani  Ginger Weade  Timothy McKeny 《Teacher Development》2017,21(3):388-403

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   

Caregiver perceptions of sexual abuse and its effect on management after a disclosure     

Walker-Descartes I  Sealy YM  Laraque D  Rojas M 《Child abuse & neglect》2011,35(6):437-447

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   

Differential susceptibility to adolescent externalizing trajectories: examining the interplay between CHRM2 and peer group antisocial behavior     

Latendresse SJ  Bates JE  Goodnight JA  Lansford JE  Budde JP  Goate A  Dodge KA  Pettit GS  Dick DM 《Child development》2011,82(6):1797-1814

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

A rapid evidence‐based service by librarians provided information to answer primary care clinical questions     

Jessie McGowan  William Hogg  Tamara Rader  Doug Salzwedel  Danielle Worster  Elise Cogo  Margo Rowan 《Health information and libraries journal》2010,27(1):11-21

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

A Sport Education Fitness Season’s Impact on Students’ Fitness Levels,Knowledge, and In-Class Physical Activity     

Jeffery Kurt Ward  Danielle D. Wadsworth  Shelby Foote  Sheri J. Brock  Nikki Hollett 《Research quarterly for exercise and sport》2017,88(3):346-351

Purpose: The purpose of this study was to determine the extent to which a sport education season of fitness could provide students with recommended levels of in-class moderate-to-vigorous physical activity (MVPA) while also increasing students’ fitness knowledge and fitness achievement. Method: One hundred and sixty-six 5th-grade students (76 boys, 90 girls) participated in a 20-lesson season called “CrossFit Challenge” during a 4-week period. The Progressive Aerobic Cardiovascular Endurance Run, push-ups, and curl-ups tests of the FITNESSGRAM® were used to assess fitness at pretest and posttest, while fitness knowledge was assessed through a validated, grade-appropriate test of health-related fitness knowledge (HRF). Physical activity was measured with Actigraph GT3X triaxial accelerometers. Results: Results indicated a significant time effect for all fitness tests and the knowledge test. Across the entire season, the students spent an average of 54.5% of lesson time engaged in MVPA, irrespective of the type of lesson (instruction, free practice, or competition). Conclusions: The results suggest that configuring the key principles of sport education within a unit of fitness is an efficient model for providing students with the opportunity to improve fitness skill and HRF knowledge while attaining recommended levels of MVPA.  相似文献   

Levels of social complexity and dimensions of peer experiences in youth sport   总被引：1，自引：0，他引：1  

Holt NL  Black DE  Tamminen KA  Fox KR  Mandigo JL 《运动与训练心理学杂志》2008,30(4):411-431

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

Effects of consecutive days of match play on technical performance in tennis     

Danielle T. Gescheit  Rob Duffield  Melissa Skein  Neil Brydon  Stuart J. Cormack  Machar Reid 《Journal of sports sciences》2017,35(20):1988-1994

Elite tennis is characterised by repeated bouts of up to 5-set match play, yet little is known about the technical requirements of shots played. This study therefore investigated technical performance changes over consecutive days of prolonged, simulated tennis match play. A total of 7 well-trained men tennis players performed 4 consecutive days of competitive 4-h match play. Matches were notated to determine between-day changes in groundstroke and serve performance, as well as point and match durations. Changes ≥75% likely to exceed the smallest important effect size (0.2) were considered meaningful and represented as effect size ± 90% confidence interval. Effective playing time reduced on days 3 and 4, alongside likely increases in “stretch” groundstrokes over the 4 days (mean effect size ± 90% confidence interval; 0.57 ± 0.38) and “stretch” backhand returns on days 2 and 3 (0.39 ± 0.54 and 0.67 ± 0.55). Relative unforced errors increased on day 4 (vs. day 2; 0.36 ± 0.22) and second-serve winning percentage reduced after day 1 (?0.47 ± 0.50). Further, a likely increase in emotional outbursts characterised day 3 (vs. day 2; 0.73 ± 0.57). Consecutive-day match play impairs hitting accuracy, stroke positioning and emotional responses; an understanding of which prepares players for elite-standard tennis tournament play.  相似文献
