The aim of the current study was to examine mean‐group differences on behavior rating scales and variables that may predict such differences. Sixty‐five teachers completed the Clinical Assessment of Behavior–Teacher Form (CAB‐T) for a sample of 982 students. Four outcome variables from the CAB‐T were assessed. Hierarchical linear modeling was used to analyze variance components across three levels; examine mean‐group differences across outcome variables for student gender, race/ethnicity, and free or reduced‐price lunch status; and examine whether teacher variables predicted teacher‐specific differences in ratings. Results revealed that a significant amount of variance was attributable to teacher‐ and school‐level variables. Several mean‐group differences emerged, and some teacher‐specific differences in ratings across groups were predicted by teacher self‐efficacy for behavior management and teacher age, but not for teacher race/ethnicity, gender, or years of experience. 相似文献

The present study was conducted to better understand the influence of the child–perpetrator relationship on responses to child sexual and physical trauma for a relatively large, ethnically diverse sample of children and youth presenting for clinical evaluation and treatment at child mental health centers across the United States. This referred sample includes 2,133 youth with sexual or physical trauma as their primary treatment focus. Analyses were conducted to ascertain whether outcomes were dependent on the perpetrator's status as a caregiver vs. non-caregiver. Outcome measures included psychiatric symptom and behavior problem rating scales. For sexual trauma, victimization by a non-caregiver was associated with higher posttraumatic stress, internalizing and externalizing behavior problems, depression, and dissociation compared to youth victimized by a caregiver. For physical trauma, victimization by a non-caregiver was also associated with higher posttraumatic symptoms and internalizing behavior problems. The total number of trauma types experienced and age of physical or sexual trauma onset also predicted several outcomes for both groups, although in disparate ways. These findings are consistent with other recent studies demonstrating that perpetration of abuse by caregivers results in fewer symptoms and problems than abuse perpetrated by a non-caregiving relative. Thus, clinicians should not make a priori assumptions that children and adolescents who are traumatized by a parent/caregiver would have more severe symptoms than youth who are traumatized by a non-caregiver. Further exploration of the role of the perpetrator and other trauma characteristics associated with the perpetrator role is needed to advance our understanding of these findings and their implications for clinical practice. 相似文献

“It’s the X and Y Thing”: Cross-sectional and Longitudinal Changes in Children’s Understanding of Genes 总被引:1,自引:0,他引:1
Studies from different theoretical traditions investigating children’s inheritance and genetics concepts have adopted a cross-sectional
method. This paper is the first to examine both cross-sectional and longitudinal changes in children’s basic genetic concepts.
It forms part of a larger investigation into the development of intuitive inheritance and genetics concepts in childhood.
Four age cohorts (4–5 years, 7–8 years, 10–11 years, 14–15 years) were interviewed individually at two measurement occasions
(T1, N = 182; T2, N = 164) separated by a 1-year interval. Cross-sectional analyses revealed an increase in children’s knowledge of genetics
by 10 years. Between 10 and 14 years, there were fewer changes in the content of children’s knowledge, especially at the level
of scientific genetic understanding. There was little evidence of longitudinal changes over the 1-year period. Overall, children
may hold an understanding of genetics that is tied to knowledge of inheritance within families. This may pose challenges for
acquiring more abstract and formal concepts of genes. 相似文献

This article draws on the findings from a small qualitative study which focused on gathering perspectives and accounts of experiences from nursery practitioners, health and third sector professionals and parents. It explored the ways in which parents/carers and practitioners experienced the nurture approach developed in preschool settings in Glasgow, Scotland and their perspectives on the impact that this provision has had on the development and well-being of young children and family engagement in learning. The findings provided some insights into the specific ways in which settings involved parents and worked towards developing a nurturing ethos towards parents themselves, underpinned by the following three elements: a welcoming setting, sensitive and empathic staff and creative practice. The particular characteristics of these three elements seemed to support some parents in developing the parenting skills which were required to consolidate the benefits experienced by their children. These benefits included parents being supported to replicate some of the practices at home and becoming more involved in their children’s learning. The study identified challenges for some nurseries in achieving this, such as the limited scope for nurture corner practitioners in some of the settings to fully utilise their skills with parents due to accommodation constraints. 相似文献

Conventional treatments of functions start by building a rule of correspondence betweenx-values andy-values, typically by creating an equation of the formy=f(x). We call this acorrespondence approach to functions. However, in our work with students we have found that acovariational appraoch is often more powerful, where students working in a problem situation first fill down a table column withx-values, typically by adding 1, then fill down ay-column through an operation they construct within the problem context. Such an approach has the benefit of emphasizing rate-of-change. It also raises the question of what it is that we want to cal rate across different functional situations. We make two initial conjectures, first that a rate can be initially understood as aunit per unit comparison and second that a unit is theinvariant relationship between a successor and its predecessor. Based on these conjectures we describe a variety of multiplicative units, then propose three ways of understanding rate of change in relation to exponential functions. Finally we argue that rate is different than ratio and that an integrated understanding of rate is built from multiple concepts. 相似文献
