In recent years attempts to improve the management of cases of child abuse have concentrated on structural procedures for achieving better coordination between agencies, at the expense of attention to less tangible factors which may impede treatment. This paper, based on a small study which analysed retrospectively cases which had resulted in the serious injury or death of a child, identifies some of these factors. The evidence suggests that the manifest level of concern for the safety of the child changes markedly in treatment, but does not correspond with the objective reality portrayed in the case material. Some underlying factors influencing this lack of congruence are: (1) formulation of the presenting problem creates a bias which becomes more pronounced through time; (2) focus on strengths and progress conceals areas of malfunctioning in the family; (3) attention to an individual masks risk to siblings; (4) concentration of attention on one adult as possible aggressor obscures contribution of others; (5) influence of any changes in family composition is not sufficiently considered. The paper discusses these findings and suggests the hypothesis that the use of a properly constructed “Index of Concern” could provide a means of counterbalancing such factors. 相似文献

Explicit instruction of the nature of science (NOS) may be problematic if the NOS is portrayed as either a solely a cognitive
or discursive endeavor, overlooking other aspects of epistemology, such as aesthetic ways of knowing. Here the aesthetic stance
refers to individual’s responses during reading as they create links between the text and their own lives, prompting personal
and emotional connections. From an aesthetic orientation, exploring historical nonfiction science texts via literature circles
allows alternative possibilities for participants to create personal connections to the NOS. This article presents practical
techniques and theoretical rationales for teaching the NOS using literature circles and concluding thoughts regarding narrative
pedagogy and research possibilities associated with this instructional approach in elementary science teacher education. 相似文献

Children of depressed mothers are at risk for behavioral and emotional problems. Infants of depressed mothers exhibit behavioral disturbances and atypical frontal brain activity. The mechanisms by which children develop such vulnerabilities are not clear. Three-year-old children of mothers with (N = 65) and without (N = 59) a history of depression were assessed in terms of behavior problems and brain electrical activity. Children of mothers with chronic depression exhibited lower frontal and parietal brain activation compared with children of mothers without depression and those whose depression remitted. Depressed mothers reported higher contextual risk (e.g., marital discord and stress) and their children had more behavior problems. Children's frontal brain activation and contextual risk level mediated the relation between maternal depression and child behavior problems. 相似文献

In this article the author points out the limitations of television as a tool in non‐formal education of adults in Africa and looks at the benefits of supplementing broadcast‐delivered messages with person‐to‐person communications. Two examples of mass media campaigns integrating various media with person‐to‐person communications in the field are described, one in Ivory Coast and another in Zaire. In both cases television, once seen as the ultimate panacea of mass education, has been reduced to a supportive role 相似文献

What to do about values in social research: the case for ethical reflexivity in the sociology of education 总被引:1,自引:0,他引:1
This paper is intended as a contribution to the longstanding debate about the best way of handling value judgements in social research. In it we make a case for more ‘ethical reflexivity’ in the sociology of education and argue that a systematic attention to value questions should be viewed as a taken‐for‐granted component of methodological rigour. We elucidate what we mean by ethical reflexivity, why we think it is important and suggest what it entails in practice. Our arguments are developed through a discussion of, and in contrast to, Martyn Hammersley’s analysis of the role of values in social research. The central problematic that the paper addresses is the tension between, on the one hand, the goal of insulating the research process from ‘value bias’ and, on the other hand, the goal of contributing to political and social change through research. We suggest that the reason for the intractability of the problem of values in social research is a persistent failure to recognise that, in practice, these two goals are inseparable. We argue that rigour in research demands that both these goals are taken seriously and we set out some of the challenges involved in trying to combine them. 相似文献

This article reviews current policy trends concerning the practice of ability grouping in K–12 science education. Relevant statements of key policy-making, policy-influencing organizations such as the NSTA, AAAS, NSF, the National Research Council, the U.S. Office of Education Department of Civil Rights, NAACP, the National Governors' Association, programs related to the Jacob Javits Grants for the Gifted and Talented, and others are summarized. The author's interpretation of the various positions are presented herein. The article also explores the research base supporting the various policies on grouping by examining selected general research literature on grouping, followed by research that is science education specific. Methodological issues color the research findings. The ethical and pragmatic implications of developing research and policy are discussed. The conclusions are that there is a dearth of recent empirical research specifically related to ability grouping in science, and that the time is ripe for the concerted development of a research agenda by key players in science education reform. Moreover, as controversial and value-laden as the topic is, it should be noted that grouping practices alone are unlikely to influence science education reform unless considered in the context of comprehensive restructuring efforts at the local school level. 相似文献

Research indicates that preservice teacher (PT) education programs can positively impact perceptions of scientific probeware use in K-8 environments. Despite the potential of probeware to improve science instruction and student engagement, its use in elementary education has been limited. Sixty-seven PT enrolled across three sections of an elementary science methods course participated in a mixed-methods study through which they utilized probeware in a thematic experience on ocean acidification. One-way repeated measures ANOVA of pre and post survey data measuring subscales of utility, ability, and intent to use probeware demonstrated a statistically significant increase with medium to large effect sizes for all subscales across all sections \( \left(p<0.01,\kern0.5em {\eta}_p^2=0.384;\kern0.5em p<0.001,\kern0.5em {\eta}_p^2=0.517;\kern0.0em p<0.001,\kern0.0em {\eta}_p^2=0.214\right) \). Analysis of reflective journals revealed over 60% felt the multiple capabilities (notably graphing) of probeware make it a useful classroom tool, and almost one-half believed that its use makes science more enjoyable and engaging. Mapping of the unitized data from the journals on the Next Generation Science Standards suggested that probeware use especially engages learners in planning and carrying out investigations and in analyzing and interpreting data. Journals also revealed that despite PT having prior experience with probeware in science courses, its use in their future elementary classroom is conditional on having a positive experience with probeware in a science methods course. Further, embedding a probeware experience in a unit on ocean acidification provides PT with strategies for addressing climate change and engaging in argument from evidence. 相似文献

Because folklore has the capability to teach and to preserve the thoughts, feelings, and beliefs of a people, suggestions are offered for using folklore to deepen children's understanding of Polynesian culture. Maori nature fables, along with error/punishment stories involving the woman or man on the moon, represent the instructive function. Tales and legends preserving cultural history are represented by a folk story reflecting values and customs of everyday life, accounts of legendary monsters reflecting cultural hopes and fears, and heroic tales of the popular demigod Maui. Specific stories are reviewed, juvenile collections are referenced, and classroom activities are offered. 相似文献

Students' conceptions of how objects are seen directly, and in mirrors, were explored in an analysis of their written and
drawn responses to common visual phenomena depicted in cartoons with brief text. Students in Grades K-10 (n=214) completed
a questionnaire and some were interviewed. Evidence was sought to support an hypothesis for increasingly sophisticated responses
related to the concepts of sight, light, reflection and image. The developmental model used in this analysis was the updated
SOLO Taxonomy (Biggs & Collis, 1991; Collis & Biggs 1991). It appears from the results that different modes of functioning
can interfere to produce factually incorrect recollections of experience particularly in the age group 7 to 13 years approximately.
Also, this is associated with the common spurious conception that mirrors have a lateral inversion property. Explanations
involving light were extremely rare and its role related to the production of an image ‘in the mirror’ but not to the perception
of an image in the eyes.
