An international wiki-based collaboration was integrated into a large introductory educational technology course enrolling
346 students, divided into 43 teams. Student teams participated in a 5-week project in which they created wiki chapters about
the educational uses of specific Web 2.0 tools. Two to four international students, located in their home countries, participated
on each team, collaborating via the evolving wiki, as well as other Web 2.0 tools. Using expectancy-value as our motivational
framework, we gathered pre- and post-survey data, triangulated with focus group interview data, to examine changes in students’
confidence and perceived value for using these tools to facilitate international collaborations. Survey results showed significant
changes in confidence and perceived value, while qualitative results provided insights into students’ perceptions of critical
project components. We discuss students’ perceptions of project barriers as well as the strategies they implemented to achieve
success. 相似文献

Although screening for child abuse at emergency departments (EDs) increases the detection rate of potential child abuse, an accurate instrument is lacking. This study was designed to measure the accuracy of a screening instrument for detection of potential child abuse used in EDs. In a prospective cohort study at three Dutch EDs, a 6-item screening instrument for child abuse, Escape, was completed for each child visiting the ED. The data from the completed Escape instrument was used to calculate sensitivity, specificity, and the positive/negative predictive value per item. The clinical notes and conclusions of the screen instruments of all potentially abused children reported to the hospitals’ Child Abuse Teams were collected and reviewed by an expert panel. A logistic regression model was used to evaluate the predictors of potential abuse. Completed Escape instruments were available for 18,275 ED visits. Forty-four of the 420 children with a positive screening result, and 11 of the 17,855 children with a negative result were identified as potentially abused. Sensitivity of the Escape instrument was 0.80 and specificity was 0.98. Univariate logistic regression showed that potentially abused children were significantly more likely to have had an aberrant answer to at least one of the items, OR = 189.8, 95% CI [97.3, 370.4]. Most of the children at high risk for child abuse were detected through screening. The Escape instrument is a useful tool for ED staff to support the identification of those at high risk for child abuse. 相似文献

The Self-Report Checklist for Social and Learning Behaviour (SSL) is a student questionnaire comparable to the Teacher Report Checklist for Social and Learning Behaviour. The SSL assesses ten facets of social and learning behaviour using self-reports by students. The present study of 1267 students aged 9 to 19 years examines the factorial structure, psychometric properties and validity of this questionnaire. The reliabilities (Cronbach’s Alpha, retest) of all ten scales were sufficiently good and the postulated factorial structure was found in exploratory as well as in confirmatory factor analysis. Correlations of SSL-scales with scales of the Differencial Aggression Questionnaire and the Strengths and Difficulties Questionnaire as well as with grades in German and mathematics indicated mainly convergent and divergent validity. Furthermore, positive correlations were found to corresponding teacher ratings. 相似文献

Oppression of the chest, cough and orthopnea are well known to occur in some athletes after competitions, maybe reflecting an increase in lung water. In order to indicate if lung water increases after maximal exercise we measured pulmonary diffusion capacity before and 2.1 h after a short maximal arm exercise bout in 11 canoeists and showed a decrease of 6.7%. The result may be explained by a calculated 17% increase in alveolar interstitial volume. 相似文献

Abstract Present athletic practices in stop-watch timing require the median of three watch times to be declared “official” time. Theoretical evidence is available that the standard error of the median is larger than the standard error of the mean when sampling is from a single, normal population. The present investigation was designed to determine if, under actual race conditions, the same relationship between the mean and median time exists. In the two independent experiments described the standard error of the median was observed to be larger than that of the mean. 相似文献

In 2014, the highly experienced Head of Electronic Resources and Serials Services at Auburn University Libraries retired. Parallel changes in workflows, staffing, and organizational structure were also taking place, resulting in an intense period of transition that included merging two units. This presentation describes the transition process from the perspective of the new Head of Technical Services and one paraprofessional staff in the merged units. The presentation focuses on the processes of change, guiding philosophies, and lessons learned. 相似文献

School psychologists (N = 276, 81% return rate) were surveyed regarding the following aspects of crisis intervention: (a) university preparation, (b) continuing professional development, and (c) current involvement with school crisis plans and crisis teams. Of those receiving university training, 58% believed they were minimally prepared or not at all prepared to deal with school crises. Only 2% reported being well prepared or very well prepared. Data analyses indicated increased university training in recent years, particularly with practicum/internship experiences related to crisis intervention. Approximately 81% of school psychologists participated in local training for crisis intervention as part of continuing professional development. Although 91% of school psychologists worked in districts with crisis plans in place, only 53% participated on crisis teams. Suicide, violence, and school district crisis plans were recommended as high priority topics for future academic training. © 2002 Wiley Periodicals, Inc. 相似文献
