Adverse childhood experiences and hallucinations     

Whitfield CL  Dube SR  Felitti VJ  Anda RF 《Child abuse & neglect》2005,29(7):797-810

OBJECTIVE: Little information is available about the contribution of multiple adverse childhood experiences (ACEs) to the likelihood of reporting hallucinations. We used data from the ACE study to assess this relationship. METHODS: We conducted a survey about childhood abuse and household dysfunction while growing up, with questions about health behaviors and outcomes in adulthood, which was completed by 17,337 adult HMO members in order to assess the independent relationship of 8 adverse childhood experiences and the total number of ACEs (ACE score) to experiencing hallucinations. We used logistic regression to assess the relationship of the ACE score to self-reported hallucinations. RESULTS: We found a statistically significant and graded relationship between histories of childhood trauma and histories of hallucinations that was independent of a history of substance abuse. Compared to persons with 0 ACEs, those with 7 or more ACEs had a five-fold increase in the risk of reporting hallucinations. CONCLUSION: These findings suggest that a history of childhood trauma should be looked for among persons with a history of hallucinations.  相似文献   

Exploring the structure of the Watson–Glaser Critical Thinking Appraisal: One scale or many subscales?     

Robert M. Bernard  Dai Zhang  Philip C. Abrami  Fiore Sicoly  Evgueni Borokhovski  Michael A. Surkes 《Thinking Skills and Creativity》2008,3(1):15-22

Critical thinking (CT) has been of longstanding interest among scholars, educators, and others who are concerned with thinking skills. The Watson–Glaser Critical Thinking Appraisal (WGCTA) is the oldest and among the most widely used and studied CT measure. It was constructed around five subscales (or CT skills): inference, recognition of assumptions, deduction, interpretation, and evaluation of arguments. This paper describes a two part analysis of the psychometric properties of the WGCTA, based on 13 sets of subscale inter-correlations and 60 sets of subscale means retrieved from published studies. We performed a meta-analysis on the inter-correlations of the10 combinations of subscales and found that all of the average correlations that resulted were significant, but that all but one was significantly heterogeneous. Subsequently, we conducted principal components analysis on 60 subscale means of two different versions of the WGCTA. Each produced a one-factor solution, accounting for 82.69% and 79.55% of the total variance, respectively. Together these two parts of this study suggest that the WGCTA should be viewed as a measure of general competency, and that the subscales should not be interpreted individually.  相似文献   

Active learning: A small group histology laboratory exercise in a whole class setting utilizing virtual slides and peer education     

Robert A. Bloodgood 《Anatomical sciences education》2012,5(6):367-373

Histology laboratory instruction is moving away from the sole use of the traditional combination of light microscopes and glass slides in favor of virtual microscopy and virtual slides. At the same time, medical curricula are changing so as to reduce scheduled time for basic science instruction as well as focusing on student‐centered learning approaches such as small group active learning and peer‐instruction. It is important that medical schools resist the temptation to respond to this conjunction of events by turning histology into a self‐study activity. This article describes a lymphoid histology laboratory exercise, occurring in a specially equipped Learning Studio housing an entire medical class that utilizes virtual slides in the context of small group active learning and peer instruction.

Is a cerebellar deficit the underlying cause of reading disabilities?     

Irannejad S  Savage R 《Annals of dyslexia》2012,62(1):22-52

This study investigated whether children with dyslexia differed in their performance on reading, phonological, rapid naming, motor, and cerebellar-related tasks and automaticity measures compared to reading age (RA)-matched and chronological age (CA)-matched control groups. Participants were 51 children attending mainstream English elementary schools in Quebec. All participants completed measures of IQ, word and nonword reading fluency, elision, nonword decoding, rapid naming, bead threading, peg moving, toe tapping, postural stability, and muscle tone. Results from both group contrasts and analyses at the individual case level did not provide support for claims of motor–cerebellar involvement in either typical or atypical reading acquisition. Results were more consistent with a phonological core process account of both typical reading and reading difficulty. Phonological deficits for children with dyslexia compared to RA-matched controls were, however, only evident in group contrasts. Findings thus also have important implications for identifying at-risk readers among their same-aged peers.  相似文献   

Types and frequencies of feedback interventions in classroom interaction in secondary education     

Lia Voerman  Paulien C. Meijer  Fred A.J. Korthagen  Robert Jan Simons 《Teaching and Teacher Education》2012

Contributing to the growing amount of literature on learning–enhancing feedback, this article attempts to distinguish between progress feedback and discrepancy feedback. Building on relevant literature drawn from psychology, we propose the use of a ratio of 3:1, positive:negative feedback. We analyzed contiguous 10 min blocks of classroom interactions from 78 teachers. Findings indicate that teachers seldom provide the types of feedback interventions identified as effective in enhancing learning in the course of typical classroom interactions. We examine potential explanations for this, discuss the consequences of this finding on teacher education and professional development, and offer several opportunities for future research.  相似文献   

Math fluency is etiologically distinct from untimed math performance, decoding fluency, and untimed reading performance: evidence from a twin study     

Petrill S  Logan J  Hart S  Vincent P  Thompson L  Kovas Y  Plomin R 《Journal of learning disabilities》2012,45(4):371-381

The authors examined whether math fluency was independent from untimed math and from reading using 314 pairs of school-aged twins drawn from the Western Reserve Reading and Math Projects. Twins were assessed through a 90-min home visit at approximately age 10 and were reassessed in their homes approximately 1 year later. Results suggested that the shared environment and genetics influenced the covariance among math fluency, untimed math measures, and reading measures. However, roughly two thirds of the variance in math fluency was independent from untimed math measures and reading, including reading fluency. The majority of this independent variance was the result of genetic factors that were longitudinally stable across two measurement occasions. These results suggest that math fluency, although related to other math measures, may also be a genetically distinct dimension of mathematics performance.  相似文献

The Delphi method: gathering expert opinion in religious education   总被引：2，自引：0，他引：2  

Vivienne M. Baumfield  James C. Conroy  Robert A. Davis 《British Journal of Religious Education》2012,34(1):5-19

The ‘Does Religious Education work?’ project is part of the Religion and Society programme funded by two major research councils in the UK. It sets out to track the trajectory of Religious Education (RE) in secondary schools in the UK from the aims and intentions represented in policy through its enactment in classroom practice to the estimations of its impact by students. Using a combination of approaches, we are in the process of investigating the practices which determine and shape the teaching of RE in secondary schools through linked case studies, semi-structured interviews and a practitioner enquiry strand. In this article we focus on the first stage of the project where we used the Delphi method to elicit expert opinion on the aims and intentions of RE in secondary schools in Scotland, England and Northern Ireland. We outline the place of the Delphi process within the rationale of the project, discuss emerging themes and some of the issues arising from the use of this approach.  相似文献   

Young learners: mapping the beliefs and practices of preschool teachers in relation to early literacy development     

Robert Brown  Janet Scull  Andrea Nolan  Bridie Raban  Jan Deans 《The Australian Educational Researcher》2012,39(3):313-331

This paper introduces the Young Learners?? Project, which is a large scale longitudinal study that aims to identify a number of factors associated with positive outcomes in literacy in the first year of school: the role of the preschool teacher, home life and child characteristics. In particular, it presents the design of one sub-study within the larger project that is focusing on the beliefs, theoretical constructs and literacy practices of 25 preschool teachers. The paper deliberates the methodological choices of a group of researchers who set out to represent in diverse ways, and for diverse purposes, the layered meanings inherent in preschool teachers?? beliefs and practices in relation to early literacy development. In particular, through reference to illustrative extracts of a single case analysis, the paper explores the possibilities and complexities of adopting mixed methods and in doing so, responds to a call for researchers to make explicit the purposes and challenges of case study methodologies.  相似文献   

Children's early child care and their mothers' later involvement with schools     

Crosnoe R  Augustine JM  Huston AC 《Child development》2012,83(2):758-772

Theory and policy highlight the role of child care in preparing children for the transition into school. Approaching this issue in a different way, this study investigated whether children's care experiences before this transition promoted their mothers' school involvement after it, with the hypothesized mechanism for this link being the cultivation of children's social and academic skills. Analyses of 1,352 children (1 month-6 years) and parents in the NICHD Study of Early Child Care and Youth Development revealed that mothers were more involved at their children's schools when children had prior histories of high-quality nonparental care. This pattern, which was fairly stable across levels of maternal education and employment, was mediated by children's academic skills and home environments.  相似文献
