The long-term impact of childhood sexual abuse in Australian women

OBJECTIVE: The aim of this study was to examine the association between childhood sexual abuse (CSA) and a range of adverse adult outcomes in a community sample of women using multivariate analysis which accounted for a number of potential confounding effects. METHOD: Retrospective study of cross-sectional data on the long-term impact of CSA, collected as part of a larger two-stage case-control study of the possible relationship between CSA and alcohol abuse. Data were appropriately weighted to adjust for the different selection probabilities of cases and controls. RESULTS: Significant associations were found between reporting CSA and experiencing domestic violence, rape, sexual problems, mental health problems, low self-esteem, and problems with intimate relationships even after taking into account a range of family background factors. Women who had experienced abuse involving intercourse were the most vulnerable to these negative outcomes. CONCLUSIONS: The findings indicate that the influence of CSA on adverse long-term effects is mediated and influenced both by the severity of the abuse experiences and by a range of family and social background factors.     

How Risky Are One-Shot Cross-Sectional Assessments of Undergraduate Students?

The purpose of this study was to explore the extent of possible input bias associated with the rapidly growing use by colleges and universities of one-time cross-sectional assessments of students. The results presented in this study demonstrate that cross-sectional assessments of enrolled college students are very difficult to interpret because they inevitably reflect characteristics of the same students when they first entered college. For those forms of engagement that have to do with how students allocate their time, it appears that the majority of variation among institutions is attributable to entering freshman characteristics rather than to institutional policies or practices. Thus, rather than relying solely on student outcome data, institutions should ideally also collect pretest or input information from the same students when they first matriculate.     

A deniable and efficient question and answer service over ad hoc social networks

When people are connected together over ad hoc social networks, it is possible to ask questions and retrieve answers using the wisdom of the crowd. However, locating a suitable candidate for answering a specific unique question within larger ad hoc groups is non-trivial, especially if we wish to respect the privacy of users by providing deniability. All members of the network wish to source the best possible answers from the network, while at the same time controlling the levels of attention required to generate them by the collective group of individuals and/or the time taken to read all the answers. Conventional expert retrieval approaches rank users for a given query in a centralised indexing process, associating users with material they have previously published. Such an approach is antithetical to privacy, so we have looked to distribute the routing of questions and answers, converting the indexing process into one of building a forwarding table. Starting from the simple operation of flooding the question to everyone, we compare a number of different routing options, where decisions must be made based on past performance and exploitation of the knowledge of our immediate neighbours. We focus on fully decentralised protocols using ant-inspired tactics to route questions towards members of the network who may be able to answer them well. Simultaneously, privacy concerns are acknowledged by allowing both question asking and answering to be plausibly deniable. We have found that via our routing method, it is possible to improve answer quality and also reduce the total amount of user attention required to generate those answers.     

Integration of physically disabled students

Abstract

The article reviews research in four areas: impact of integration on children's self‐concept, attitudes toward physically disabled children, effects on their school achievement and teacher reactions to integration. Research evidence suggests that being together with non‐disabled peers makes the disabled child more aware of his physical impairment and restraints. But there are also signs indicating that psychological factors essential for a positive self‐evaluation are activated to a higher degree in the integrated environment. With respect to attitudes of peers there are some, although not conclusive, results suggesting positive influence of integration. Research on school achievement demonstrates the great variability among the physically disabled pupils, in comparison with which the impact of school placement is relatively minor. Teacher opinions about integration of physically disabled pupils are mainly positive, but if the handicap is severe integration is considered possible only with a rich supply of teaching material, reduced class size and support from specialists. The review concludes with glimpses from reports on practical experience with integration.     

What is ‘Agency’? Perspectives in Science Education Research

The contemporary interest in researching student agency in science education reflects concerns about the relevance of schooling and a shift in science education towards understanding learning in science as a complex social activity. The purpose of this article is to identify problems confronting the science education community in the development of this new research agenda and to argue that there is a need for research in science education that attends to agency as a social practice. Despite increasing interest in student agency in educational research, the term ‘agency’ has lacked explicit operationalisation and, across the varied approaches, such as critical ethnography, ethnographies of communication, discourse analysis and symbolic interactionism, there has been a lack of coherence in its research usage. There has also been argument concerning the validity of the use of the term ‘agency’ in science education research. This article attempts to structure the variety of definitions of ‘student agency’ in science education research, identifies problems in the research related to assigning intentionality to research participants and argues that agency is a kind of discursive practice. The article also draws attention to the need for researchers to be explicit in the assumptions they rely upon in their interpretations of social worlds. Drawing upon the discursive turn in the social sciences, a definition of agency is provided, that accommodates the discursive practices of both individuals and the various functional social groups from whose activities classroom practice is constituted. The article contributes to building a focused research agenda concerned with understanding and promoting student agency in science.     

Extract from new understandings of teachers' pedagogic knowledge 1

Abstract

The focus of this article is a comparative review of the science curriculum for England and Wales from the perspective of recent developments in the United States of America, Australia, New Zealand and the Canadian province of Ontario. In the comparison of science curriculum documents and the language deployed, questions are raised about differences as well as commonalities among and between documents from various jurisdictions. Issues discussed include: the varying emphases upon science topics and/or intended learning outcomes; integration with other curriculum areas; the content and organization of the science curriculum; and ways of assessing students’ performances and understandings. The article draws attention to the importance of comparative analysis which informs our understanding of the effects of curriculum change, its relation to students’ achievements in science, and the need to support the development of teachers.     

Students as meaning-makers and the quest for the common school: A micro-ethnography of a US history classroom

This study examined the extent to which (a) nine US history students developed historically-grounded perspectives, and (b) the entire class engaged itself in inclusive, moral debate about historical events and issues. Inductive methods were used in this micro-ethnographic study to construct and verify its themes though interview, classroom observation and student survey. Seven students demonstrated identifiable perspectives. History was viewed by these students as personally-constructed interpretations, not as value-free chronologies. Only one student's perspective, however, was historically-grounded; other perspectives were grounded in references to contemporary issues. Evidence of moral debate was limited totwo debates observed during 24 classroom observations. These two findings seemed interconnected: students with little historical grounding to their perspectives may have little inclination toward collective, ethical critique. Moral debate consisting of student exchange of diverse historically-grounded perspectives was not the classroom norm. The debates that went into the making of American society concerned not just institutions or governing principles, but the capacity of humans to sustain those institutions. Whatever the disagreements were over other issues at the American Constitutional Convention \[in Philadelphia in 1787], the fundamental question sensed by everyone … was whether the people themselves would understand what it meant to hold the ultimate power of society, and whether they had enough sense of history and destiny to know where they had been and where they ought to be going.

Of sheep's pluck and science exhibitions: the professional life of Mother Bernard Towers RSM (1883–1963)

An examination of the professional lives of women science teachers presents an opportunity to consider ways in which women became ‘knowledge purveyors’ and to reflect on the extent to which they challenged contemporary boundaries about what science women should know. An analysis of the life of a woman science teacher who was also a ‘professed’ religious illuminates the complexity of a professional life shaped by an overlay of vocation and employment. Mother Bernard Towers's teaching life extended over the greater part of the twentieth century. As a science teacher she was influenced by changing understandings of the gendered science curriculum and the cultural and religious environment in which she lived. At the same time she challenged contemporary constraints on the teaching of science to girls, helped her pupils gain access to high‐status ‘hard’ science options and expanded the kinds of science that they could expect to know.
