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

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

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

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

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

This photo essay updates research previously presented in Visual Communication Quarterly about news characterizations of a “Black neighborhood” in Iowa City, Iowa. Shot by preschoolers in the city's Southeast Side, the images in this essay—peppered with the inadvertent appearance of the photographers' fingers—added to an artistic value that cast life there being other than dangerous, dark, and devious. Whereas hands can often be used to conceal, the fingers in these photographs frame special and specific glimpses of life, ultimately presenting a counternarrative to neighborhood characterizations constructed by news photographs.  相似文献

The genetic effects on individual differences in reading development were examined using genome‐wide complex trait analysis (GCTA) in a twin sample. In unrelated individuals (one twin per pair, = 2,942), the GCTA‐based heritability of reading fluency was ~20%–29% at ages 7 and 12. GCTA bivariate results showed that the phenotypic stability of reading fluency from 7 to 12 years (= 0.69) is largely driven by genetic stability (genetic = 0.69). Genetic effects on print exposure at age 12 were moderate (~26%) and correlated with those influencing reading fluency at 12 (genetic r = 0.89), indicative of a gene–environment correlation. These findings were largely consistent with quantitative genetic twin analyses that used both twins in each pair (= 1,066–1,409).  相似文献

This paper presents a small group computing environment in which four students each control a different point in a geometric space, such that as a group they collectively manipulate the vertices of a quadrilateral. Prior research has revealed that students have considerable difficulty in learning about the interrelationships among quadrilaterals shapes. In this study, we investigated how a designed environment can help support students’ learning in this area. In particular, in a case study of two student groups, we used the notions of appropriation and objectification to explain how students learned from one another different ways of using the technology and of explaining geometric concepts to progress in their geometric reasoning. When the students did not attain a shared focus of attention, they were not able to appropriate others’ approaches to using the technology or explaining geometric concepts. In one group, although some individuals demonstrated learning gains, when the coordination among the group members fell apart, not all the members were able to benefit. On the other hand, another group which demonstrated more group-oriented behavior—listening to one another, sharing the same focus of attention, engaging in coordinated actions—was able to benefit as a whole and did better overall on individual assessments.  相似文献
