Prevalence and demographic correlates of childhood maltreatment in an adult community sample 总被引:3,自引:0,他引:3
PURPOSE: This study had two aims: (1) to determine the prevalence of five categories of retrospectively reported childhood maltreatment in an adult community sample and (2) to examine relationships between three theoretically and practically chosen demographic variables and childhood maltreatment. METHOD: Participants were a representative sample of 967 adult men and women in the metropolitan Memphis, Tennessee area. They completed a telephone survey that included a reliable, valid questionnaire assessing five types of childhood maltreatment (i.e., emotional abuse, emotional neglect, physical abuse, physical neglect, and sexual abuse) and demographic questions. Simultaneous logistic regression analyses were used to identify demographic correlates of specific trauma types. RESULTS: Prevalence of childhood maltreatment ranged from approximately 30% for women to over 40% for men. Approximately 13% of participants reported multiple forms of maltreatment. The most common forms of trauma for both men and women were physical abuse, physical neglect, and emotional abuse, all of which were highly likely to co-occur. Race, sex, and current educational level were each associated with an increased likelihood of childhood maltreatment; differential relationships with particular maltreatment types were also observed. IMPLICATIONS: These findings highlight the importance of research on the prevalence of and risks for multiple types of childhood maltreatment, particularly in the somewhat neglected area of emotional abuse and neglect. These findings can be used to highlight the need for preventive interventions aimed at the negative sequelae of childhood maltreatment and to tailor preventive interventions to the needs and expectations of those at high risk. 相似文献

Career theorists emphasize the importance of the development of career maturity in adolescents if they are to successfully negotiate the school-to-work transition. Transitions of deaf and hard of hearing adolescents may be especially problematic. The authors examine the implications of current labor market trends for young people, in particular those with hearing loss, and review data on employment outcomes for deaf and hard of hearing people. They discuss the environmental and attitudinal barriers that can influence the career outcomes of this population, consider the impact of hearing loss on adolescents' career maturity, and review the studies on this topic in the literature. The article focuses on the experiences of students with significant hearing loss who are educated in regular classes with the support of itinerant teachers, who communicate orally, and who may be defined as hard of hearing. Recommendations for research and practice are provided. 相似文献

A Conceptual Framework for Learning to Teach Secondary Mathematics: A Situative Perspective 总被引:1,自引:1,他引:1
Dominic Peressini Hilda Borko Lew Romagnano Eric Knuth Christine Willis 《Educational Studies in Mathematics》2004,56(1):67-96
This paper offers for discussion and critique a conceptual framework that applies a situative perspective on learning to the
study of learning to teach mathematics. From this perspective, such learning occurs in many different situations -- mathematics
and teacher preparation courses, pre-service field experiences, and schools of employment. By participating over time in these
varied contexts, mathematics teachers refine their conceptions about their craft -- the big ideas of mathematics, mathematics-specific
pedagogy, and sense of self as a mathematics teacher. This framework guides a research project that traces the learning trajectories
of teachers from two reform-based teacher preparation programs into their early teaching careers. We provide two examples
from this research to illustrate how this framework has helped us understand the process of learning to teach.

Applying a structural equations modelling methodology, the study analyses the relationships and effects of self-regulated learning (social interaction learning strategies and motivation) and first-year university experiences on permanence in the sophomore year. The participants are 239 first-year students in different Engineering degrees at a public university in south-eastern Spain. Two alternative structural models are evaluated, showing the superiority of the model where first-year university experiences completely mediate the effects of self-regulated learning on permanence. Motivation and social interaction learning strategies show direct effects on first-year university experiences, and first-year university experiences, in turn, show direct effects on permanence; additionally, both motivation and social interaction learning strategies have indirect effects on permanence via first-year university experiences. The noteworthy theoretical implications of the results are discussed, as well as the teaching methodology and support services provided to first-year university students. 相似文献

In early childhood education and early childhood teacher preparation, science is often a challenging academic content area. However, young children are primed for science learning, and early science learning is important for later science achievement. The current study presents an embedded case study of one early childhood teacher preparation program that undertook a process of infusing and aligning science teaching preparation across a curriculum preparing preservice teachers to work with children ranging in age from birth through third grade. Major themes fell into the three categories—motivation for change; the process of improving and aligning across a program; and science attitudes, beliefs, and experiences in the midst of change. Implications are discussed in terms of improving preparation for teaching early science and aligning across courses in early childhood teacher preparation. 相似文献

The R-SPQ-2F is an instrument used in many studies to measure learning approaches. However, its internal structure is still a matter of debate. It is important to confirm its underlying structure in order to find out which variables are being measured with it. A survey method is used with 279 students of the Faculty of Education at the University of León, and alternative models found in the literature are compared using covariance structure analysis, specifically, Confirmatory Factor Analysis (CFA). We conclude that the structure that best fits the data is a two-factor structure in line with the results obtained in other studies. Future research should take these two primary factors into account when interpreting their findings. Solutions are also offered for improving the scale with the original 20 items. 相似文献

The study investigates the transdisciplinary teaching of education for sustainable development (ESD) with a global dimension at an upper secondary school in Sweden. The purpose was to analyse and describe variations in how nine teachers in different subject matters experienced collaborative teaching in the context of a whole school educational development project. A total of 27 semi-structured interviews were conducted and analysed using phenomenographic method and contextual analysis. Two main approaches to transdisciplinary teaching were identified among the teachers: one where teachers contributed but struggled with transdisciplinarity, and the other where they displayed ownership and were able to reconceptualise the project as a whole. Overall, teachers worked in the project with deep-level processing for learning ESD in an integrated manner in the transdisciplinary framework. However, they also experienced tensions between their resources and capabilities, and the challenges they faced in the project. 相似文献

AbstractThis systematic review extends the boundary of prior reviews in the environmental education (EE) field by analyzing publications focused on Latin America and the Caribbean (LATAM). We examined peer-reviewed literature and dissertations/theses in four languages (English, French, Spanish and Portuguese) published between January 2000 and February 2018 to examine outcomes of EE interventions occurring in both formal and nonformal settings among LATAM youth up to age 18 years. Our findings reflect recurring critiques of EE, such as the field’s limited empirical research and a bias toward measuring knowledge gain. Our findings also highlight themes specific to LATAM, related to issue-based EE programs, EE versus Education for Sustainable Development, barriers to EE implementation and potential challenges posed by bias, privilege and power in LATAM-based EE research. Access to potentially appropriate publications was limited by weaknesses in search databases. Only a small selection of LATAM countries is represented in publications that met the search criteria, limiting our capacity to draw stronger conclusions about the region as a whole. 相似文献

"Do I need to know this for the exam?" Using popular media, inquiry-based laboratories, and a community of scientific practice to motivate students to learn developmental biology 下载免费PDF全文
One of the greatest challenges instructors face is getting students to connect with the subject in a manner that encourages them to learn. In this essay, we describe the redesign of our Developmental Biology course to foster a deeper connection between students and the field of developmental biology. In our approach, we created a community of scientific practice focused on the investigation of environmental impacts on embryonic development and informed by popular and scientific media, the students' own questions, and the instructor. Our goals were to engage students in meaningful ways with the material, to develop students' science process skills, and to enhance students' understanding of broad principles of developmental biology. Though significant challenges arose during implementation, assessments indicate using this approach to teach undergraduate developmental biology was successful. 相似文献
