OBJECTIVES: To show that exposure to childhood maltreatment deteriorates, whereas exposure to adulthood military violence mobilizes social support; second, to show that associations between traumatic events and mental health problems are mediated through social support and, subsequently, adulthood military violence is associated with low level and childhood maltreatment with high level of mental health symptoms; third, to explore whether the moderating (protecting) effect of sufficient and satisfactory social support would differ among victims of childhood maltreatment and adulthood military violence. METHOD: The participants were a random-sample of Palestinian men and women (n=585) of 16-60 years of age. Exposure to military violence in adulthood was assessed by the Harvard Trauma Questionnaire (HTQ_I), and to childhood maltreatment by a 13-item questionnaire developed for the study. A Social Network Schedule was applied to assess the function, source, and satisfaction with social support, and the Revised SCL90-R Symptoms Checklist to assess mental health symptoms. RESULTS: Findings supported our hypothesis that exposure to childhood maltreatment was associated with low levels of social support, whereas exposure to adulthood military violence was associated with high levels of social support. Contrary to our second hypothesis, both childhood maltreatment and adulthood military violence were associated with high levels of mental health symptoms. Finally, high level and satisfactory social support moderated the association between exposure to military violence in adulthood and mental health symptoms, but not between childhood maltreatment and mental health symptoms. CONCLUSION: The findings emphasize that the nature of trauma, that is, whether familial or political, determines the availability of protective resources versus vulnerability, which should be considered when tailoring interventions to trauma victims. 相似文献
Background: For the past decade, science educators have been exploring the use of Socio-scientific Issues (SSI) as contexts for science teaching and learning, and research indicates that doing so can support significant learning gains. However, research related to how teachers take up the practice of SSI-based instruction is far more limited, due in part to a lack of tools for use in this kind of research.
Purpose: The focus of this research is development and testing of a new classroom observation protocol specifically designed for SSI-based instructional contexts.
Design and methods: Development of this SSI-Observation Protocol (SSI-OP) took place in four distinct phases: review of existing protocols and SSI-based instruction frameworks, writing and revision of protocol items, initial testing of the draft protocol, and soliciting feedback from SSI experts.
Sample: Following the four stages of SSI-OP development, we progressed to a series of field tests. The field tests were conducted with three different samples. The first sample was an experienced (10 + years) high school biology teacher and one of her honors biology classes. The second sample consisted of seven Turkish Pre-service Science Teachers (PST) participating in a science methods course. The third sample included two Thai PST from a field experience course embedded within a teacher education program.
Results: The final version of the protocol addressed five dimensions of SSI-based instructional activities: focus of instruction, teaching moves, role of teacher, role of students, and classroom environment.
Conclusions: The SSI-OP could be used in a variety of ways for research including documentation of current practices, impacts of professional development and/or curricula on teaching practices, and changes in teaching over time. We offer the SSI-OP as a new tool with the potential to contribute to science teacher education and research that may advance the teaching and learning of science through SSI. 相似文献
The form factors of handheld computers make them increasingly popular among K-12 educators. Although some compelling examples
of educational software for handhelds exist, we believe that the potential of this platform are just being discovered. This
paper reviews innovative applications for mobile computing for both education and entertainment purposes, and then proposes
a framework for approaching handheld applications we call “augmented reality educational gaming.” We then describe our development
process in creating a development platform for augmented reality games that draws from rapid prototyping, learner-centered
software, and contemporary game design methodologies. We provide a narrative case study of our development activities spread
across five case studies with classrooms, and provide a design narrative explaining this development process and articulate
an approach to designing educational software on emerging technology platforms. Pedagogical, design, and technical conclusions
and implications are discussed.
Research has shown that video games can be good for learning, particularly for STEM topics. However, in order for games to be scalable and sustainable, associated research must move beyond considerations of efficacy towards theories that account for classroom ecologies of students and teachers. This study asks how a digital game called Citizen Science, built using tropes and conventions from modern games, might help learners develop identities as citizen scientists within the domain of lake ecology. We conducted an expert-novice study, revealing that games literacy was a mediating variable for content understanding. In a follow-up classroom implementation, games literacy also operated as a variable, although students drove the activity, which mediated this concern. The teacher devised a number of novel pedagogies, such as a field trip, in response to the unit. We found evidence for the most powerful learning occurring through these activities that were reinforced via the curriculum. Students were most engaged by Citizen Science??s most ??gamelike?? features, and learners took up the core ideas of the game. Users also reported the experience was short of commercial gaming experiences, suggesting a tension between game cultures for learning and schools. 相似文献
Since the beginning of their settlement in Britain, Muslims have had to face the challenges of adapting to a new social, cultural and economic environment, and also that of responding to the opportunities provided by the new environment. A particularly sticking challenge facing the Muslim community in Britain is in the field of education. Over the last four decades, a group of Muslim voluntary organizations has emerged which is characterised by its keen interest in the public education system of this country. Muslim voluntary organizations have been playing a key role in the educational debate pertaining to the nature of religious education, and the scope of moral and spiritual development in the school curriculum. In addition, these organizations have been active, through a process of consultation and collaboration, in providing educational services to state schools, local education authorities and government departments. This paper examines the development of such voluntary organizations and attempts to discern their role and impact on the public education system in Britain. 相似文献
Public libraries play an important part in the development of a community. Today, they are seen as more than store houses of books; they are also responsible for the dissemination of online, and offline information. Public access computers are becoming increasingly popular as more and more people understand the need for internet access. Using a series of surveys conducted in 12 libraries across the state of Michigan, the current study is a step towards understanding why the computing facilities are widely used, and what are the motivations behind their use. In addition, barriers and other factors that hinder usage are also discussed. The findings from this study will help policy makers and library administrators evaluate the current allocation of scarce resources, help them promote greater use of the library's resources, and guide their future course of action. The study is conducted as part of a federally funded public computing center grant. 相似文献
Treading in the footsteps of past generations, Ontario policy advisers journeyed throughout the United Kingdom in the summer of 1966 to directly understand the educational reforms that were being undertaken in that country. On their return, these consultants brought back a number of innovations for discussion with their parent committee in the hopes of possible adaptation by the province. When their final submission was tabled two years later, the ‘Hall-Dennis Report’ (as it became popularly known) went on to reflect the tone for education in the province for a generation. This study examines the impact that Britain’s educational policies in the 1960s, and especially the ‘Plowden Report’ of 1967, may have had on the recommendations found in the Hall-Dennis Report. As well, it ties these two reports to the longstanding legacy of British influence on the Ontario education system11A first version of this work was presented at the History of Education Society Conference, held in London, 26–28 November 2010.
