Middle school students with learning disabilities often struggle with reading and literacy skills, including vocabulary, and require support in content-area classes such as mathematics where weak vocabulary knowledge can negatively affect learning, achievement, and deep understanding. However, in general, middle school mathematics teachers do not receive training in literacy instruction, much less in explicit vocabulary instruction. Additionally, relatively few studies have examined content-area vocabulary instruction at the middle or secondary school level. This study addressed these gaps in the research by examining the effect of a performance feedback and coaching intervention on middle school mathematics teachers’ use of explicit mathematics vocabulary instruction. Results of the study indicate that performance feedback and coaching had moderately positive effects on teachers’ use and quality of explicit mathematics vocabulary instruction.  相似文献

The purpose of this study is describe the initial feasibility, reliability, and validity of an instrument to measure physical activity in preschoolers using direct observation. The System for Observing Fitness Instruction Time for Preschoolers was developed and tested among 3- to 6-year-old children over fall 2008 for feasibility and reliability (Phase I, n=67) and in fall 2009 for concurrent validity (Phase II, n=27). Phase I showed that preschoolers spent >75% of their active time at preschool in light physical activity. The mean inter-observer agreements scores were ≥.75 for physical activity level and type. Correlation coefficients, measuring construct validity between the lesson context and physical activity types with and with the activity levels, were moderately strong. Phase II showed moderately strong correlations ranging from .50 to .54 between the System for Observing Fitness Instruction Time for Preschoolers and Actigraph accelerometers for physical activity levels. The System for Observing Fitness Instruction Time for Preschoolers shows promising initial results as a new method for measuring physical activity among preschoolers.  相似文献

Guided by the emotional security hypothesis developed by Davies & Cummings (1994), studies were conducted to test a conceptual refinement of children's adjustment to parental conflict in relation to hypotheses of other prominent theories. Study 1 examined whether the pattern of child responses to simulations of adult conflict tactics and topics was consistent with the emotional security hypothesis and social learning theory in a sample of 327 Welsh children. Supporting the emotional security hypothesis, child reports of fear, avoidance, and involvement were especially prominent responses to destructive conflict. Study 2 examined the relative roles of child emotional insecurity and social-cognitive appraisals in accounting for associations between parental conflict and child psychological symptoms in a sample of 285 Welsh children and parents. Findings indicated that child emotional insecurity was a robust intervening process in the prospective links between parental conflict and child maladjustment even when intervening processes proposed in the social-cognitive models were included in the analyses. Studies 3 and 4 explored pathways among parental conflict, child emotional insecurity, and psychological adjustment in the broader family context with a sample of 174 children and mothers. Supporting the emotional security hypothesis, Study 3 findings indicated that child insecurity continued to mediate the link between parental conflict and child maladjustment even after specifying the effects of other parenting processes. Parenting difficulties accompanying interparental conflict were related to child maladjustment through their association with insecure parent-child attachment. In support of the emotional security hypothesis, Study 4 findings indicated that family instability, parenting difficulties, and parent-child attachment insecurity potentiated mediational pathways among parental conflict, child insecurity, and maladjustment. Family cohesiveness, interparental satisfaction, and interparental expressiveness appeared to be protective factors in these mediational paths. No support was found for the social learning theory prediction that parent-child warmth would amplify associations between parental conflict and child disruptive behaviors.  相似文献

The authors offer a rationale, structure, and method for teaching an experientially based class in using the arts as an adjunct to counseling. They describe the benefits to counseling students, review literature documenting the effective uses of the arts in counseling, and recommend textbooks and other resources. Professional and ethical considerations are noted, suggestions for collaborative teaching are offered, and the authors' experience in piloting such a course is documented.  相似文献

Large-scale, robust implementation of teacher data-driven decision making (DDDM) is a challenging endeavor, impeded by numerous organizational, and teacher, factors. One well-documented barrier to teacher DDDM is underdevelopment of teacher data literacy. This study examines common errors made by pre-service elementary teachers in the formulation of evidence-based claims about student cognition (e.g. student strengths and weaknesses relative to content mastery) in a United States of America context. Teachers in the sample commonly made several errors in the articulation of evidence-based claims based on classroom assessments, including providing nonspecific, irrelevant evidence for claims, and misinterpreting statistical evidence. Specific implications for pre-service teacher education and future research are discussed.  相似文献

Mothers' representations of their infants may influence early development of emotional self-regulation. This study examined the associations between characteristics of mothers' (N = 100) narratives about their 7-month-old infants, maternal depression, and their infants' affect regulation during the Still Face procedure. Findings showed that (1) mothers' representations were linked with individual differences in their infants' behavior across the Still Face procedure, (2) the association between mothers' representations and their infants' behavior was mediated by parenting behavior, and (3) mothers' representations explained unique variance in their infants' affect regulation beyond the contribution of maternal depression. Although infants' displays of positive affect diminished while mothers held a still face, only infants of mothers in the balanced representation category returned to high levels of positive affect upon resuming interaction. These findings highlight the role of maternal representations in the process by which dyads repair temporary disruptions in interaction, as well as individual differences in infants' and mothers' responses to the Still Face.  相似文献

This article evaluates the extent to which infants' expressive modalities of face, gaze, voice, gesture, and posture form coherent affective configurations and whether these configurations are related to specific interactive contexts. 50 6-month-old infants and their mothers were videotaped in Tronick's Face-to-Face Still-Face Paradigm. The infants' gaze, voice, gestures, self-regulatory, and withdrawal behaviors were coded with the Infant Regulatory Scoring System (IRSS). The infants' facial expressions were coded with Izard's AFFEX system. Contingency analyses of IRSS behaviors and AFFEX expressions revealed 4 distinct affective configurations: Social Engagement, Object Engagement, Passive Withdrawal, and Active Protest. These affective configurations were differentially distributed among the different interactive contexts of the Face-to-Face Still-Face Paradigm. It is suggested that behaviors and facial expressions are fundamental expressive units flexibly organized into configurations that convey messages about the infant's internal state and intentions. Furthermore, it is hypothesized that the basic units of the infant's experience are these distinct affective configurations of emotion and behavior.  相似文献

The results of previous research suggest that while preschool children have a beginning understanding of disabilities that involve the use of adaptive equipment, they have little awareness of disabilities such as Down syndrome which have less overt distinguishing characteristics. In this study, videotaped segments from the children's television show, Sesame Street, were used to explore children's ideas about Down syndrome and physical disability. Participants included 41 preschool children. While a majority of participating children were aware that each child in the videotapes had some difficulties performing age-appropriate tasks, children had significantly fewer ideas about why the child with Down syndrome had this difficulty. Significantly more thought that the child with Down syndrome could do more “if he tried really hard” when compared with the child with a physical disability. These results are discussed in terms of children's developing understanding of disabilities and implications for using media to teach preschoolers about people with disabilities.  相似文献

This study examines the contribution of print exposure to oral language (expressive vocabulary and listening comprehension) and reading (word reading and reading comprehension) in first and second grade in Chile, and tests whether the contribution of print exposure to reading comprehension is mediated by language and word reading skills. Two‐hundred and eighty one children (mean age 6.55 years) participated. Print exposure was measured with a book‐cover recognition task in first grade, and outcomes were measured both in first and second grade. Print exposure had direct effects on all outcomes in first grade and indirect effects in second grade. Effects on first grade reading comprehension were partially mediated by listening comprehension and word reading, but not vocabulary. We discuss the importance of the findings for improving reading comprehension in countries with low access to books.  相似文献
