ABSTRACT

Using samples of novice and advanced consultants in training (CITs), this study explored the development of consultation self-efficacy (CSE) for both process-oriented and problem-oriented aspects of consultation. Regardless of experience level, self-efficacy in both domains increased with training. However, significantly greater gains were made by novice CITs as compared to their advanced counterparts. In addition, feedback collected from consultees was generally favorable, and consultants received high ratings on items that reflected both process- and problem-focused skills. Implications for consultation training are discussed.  相似文献

This study describes the development of emotional and behavioral regulation in a regional cohort of children born extremely preterm (<28 weeks gestational age, n = 39), very preterm (<34 weeks gestational age, n = 56), and full term (n = 103). At 2 and 4 years, children born at younger gestational ages demonstrated poorer self-regulation across multiple contexts spanning observed interactions, formal cognitive testing, and parental report of child behavior at home. Among children born preterm, the 2 strongest predictors of impairments in self-regulation were the presence of moderate-to-severe cerebral white matter abnormalities on neonatal magnetic resonance and a less sensitive parenting style when children were aged 2 years. Findings support the importance of early neurological development and parenting for developing regulation in children born very preterm.  相似文献

Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts.  相似文献

Estimating treatment effects for subgroups defined by posttreatment behavior (i.e., estimating causal effects in a principal stratification framework) can be technically challenging and heavily reliant on strong assumptions. We investigate an alternative path: using bounds to identify ranges of possible effects that are consistent with the data. This simple approach relies on fewer assumptions and yet can result in policy-relevant findings. As we show, even moderately predictive covariates can be used to substantially tighten bounds in a straightforward manner. Via simulation, we demonstrate which types of covariates are maximally beneficial. We conclude with an analysis of a multisite experimental study of Early College High Schools. When examining the program's impact on students completing the ninth grade “on-track” for college, we find little impact for ECHS students who would otherwise attend a high-quality high school, but substantial effects for those who would not. This suggests a potential benefit in expanding these programs in areas primarily served by lower quality schools.  相似文献

Building a metacognitive model of reflection   总被引:2,自引:0,他引:2  
An increased value is being placed on quality teaching in higher education. An important step in developing approaches to better instruction is understanding how those who are successful go about improving their teaching. Thus, several years ago we undertook a program of research in which the concept of reflection provided the frame of reference. We envisaged reflection as a process of formative evaluation, and also saw links between reflection and metacognition. What we have documented and analyzed in detail are the reflective processes of six university professors in their day-to-day planning, instructing and evaluating of learners. The result is a metacognitive model and coding scheme that operationalize the process of reflection. Both provide a language for describing reflection and therefore a way to think about how to improve teaching. In this paper, we describe the research and the model and the contributions they make to our understanding of teacher thinking in higher education.  相似文献

This paper documents the effectiveness of a substitute activity in decreasing the frequency of eye poking in a 3‐year‐old nonretarded visually impaired child who was involved in a highly participatory, full‐day reading program with four sighted classmates. Following 49 days of training, eye poking had been eliminated, and the subject was able to read 25 word cards. Elements to consider when selecting a substitute activity to interrupt an established self‐stimulating behaviour such as eye poking are discussed.  相似文献

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students. We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP) Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora, Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year. This study was made possible by the support of the National Institute of General Medical Sciences, NIH Grant Number 1 RO1 GMO71968-01. This independent research and the views expressed here do not indicate endorsement by the sponsor.  相似文献
