AbstractThis issue is the second of a special PRIMUS two-part issue collecting articles on undergraduate research from experienced faculty mentors. We offer it as a valuable resource for faculty leading undergraduate research programs. This issue presents a collection of papers offering advice on a variety of specific topics important for leaders of undergraduate research programs. Issues of finding and designing appropriate and accessible research projects, assessing undergraduate research, and publicizing it in the media are addressed. 相似文献

Research Findings: The aim of this study was to provide an initial investigation into the psychometric properties of the Problems in Classroom Engagement Scale (PCES). The PCES was designed and tested for district-wide use as part of the report card system for a large urban school district. The PCES was administered to all 1st-, 2nd-, and 3rd-grade students in the district. Factor analytic examination revealed a bifactor structure as the best fit to the data. The bifactor structure reflected a general factor of Problems in Behavioral Engagement and two group factors: Problems in Social Engagement and Problems in Academic Engagement. These factors were found to be reliable within and across grades and demonstrated convergent and divergent relations with academic and behavioral outcomes. Practice or Policy: Findings provide initial evidence to support the routine use of the PCES in a large urban setting. The use of the PCES can help in fostering district-wide attention to students’ early difficulties with behavioral, social, and academic engagement. 相似文献

More organizational leaders are recognizing that their greatest competitive advantage is the knowledge base of their employees and for organizations to thrive knowledge management (KM) systems need to be in place that encourage the natural interplay and flow of tacit and explicit knowledge. Approaching KM through the lens of the knowledge life cycle allows for the design and development of KM solutions that are systemic and address the dynamic nature of organizational knowledge. In this paper we provide a review of the literature regarding how organizational knowledge may be studied and propose a methodological framework for investigating the knowledge life cycle. To illustrate the framework we present a recent case study in which it was successfully used. This framework is intended to be useful to learning and performance improvement professionals who work in organizational KM as well as to researchers who wish to conduct further research in this area. 相似文献

Although progress has been made, greater efforts are needed to promote faculty diversity at the college and university levels,
especially in STEM fields. Thus, it is important to elucidate best practices both for increasing awareness of diversity issues
pertaining to higher education and for implementing change. This article focuses on the outcomes of a diversity workshop for
college and university faculty hosted by the West Virginia Higher Education Policy Commission, Division of Science and Research.
More specifically, it elucidates how participation in the workshop translated into practice at the faculty participants’ home
institutions. 相似文献

The interactionist model (IM) of human development (R. D. Conger & M. B. Donellan, 2007) proposes that the association between socioeconomic status (SES) and human development involves a dynamic interplay that includes both social causation (SES influences human development) and social selection (individual characteristics affect SES). Using a multigenerational data set involving 271 families, the current study finds empirical support for the IM. Adolescent personality characteristics indicative of social competence, goal-setting, hard work, and emotional stability predicted later SES, parenting, and family characteristics that were related to the positive development of a third-generation child. Processes of both social selection and social causation appear to account for the association between SES and dimensions of human development indicative of healthy functioning across multiple generations. 相似文献

Objective
We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.Methods
From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.Results
There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.Conclusion
This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system. 相似文献108.

This paper focuses on the perspectives of Years 7 and 8 Pasifika students on mathematics learning, in particular their views about the communication of solution strategies with others (their peers), and their teacher. Pasifika students' ideas about the importance of communicating their mathematical reasoning and strategies to peers and teachers were analysed and themes identified. While most students were in agreement about the importance of explaining their thinking to others, there was considerable variation in the reasons they gave for their views. The findings are interpreted in relation to socio-cultural theory and recent writing about requirements for citizenship in the twenty-first century. 相似文献

Within the self-determination theory (Deci & Ryan, 2000) framework, research has considered the consequences of coaches' autonomy supportive and controlling behaviors on various athlete outcomes (e.g., motivation and performance). The antecedents of such behaviors, however, have received little attention. Coaches (N = 443) from a variety of sports and competitive levels completed a self-report questionnaire to assess their psychological need satisfaction, well-being and perceived interpersonal behaviors toward their athletes. Structural equation modeling demonstrated that coaches' competence and autonomy need satisfaction positively predicted their levels of psychological well-being, as indexed by positive affect and subjective vitality. In turn, coaches' psychological well-being positively predicted their perceived autonomy support toward their athletes, and negatively predicted their perceived controlling behaviors. Overall, the results highlight the importance of coaching contexts that facilitate coaches' psychological need satisfaction and well-being, thereby increasing the likelihood of adaptive coach interpersonal behavior toward athletes. 相似文献
