The aim of the study was to describe students’ and teacher educators’ practical experience with action research and to identify a number of special points for consideration (opportunities and limitations) which could play a role in putting research into practice in concrete terms in the courses. Students and teacher educators on three Dutch initial teacher education programmes which treat action research as both a means of professional development and a necessary professional qualification were involved. These were programmes for specific teaching levels and subjects in Dutch schools. Four special points for consideration are identified: action research and the educational core qualifications of the profession; difference between action research by student teachers during their initial education and experienced teachers in their own workplace; students’ mixed experiences and perceptions of research; and embedded research‐based activities in the programme. The authors conclude that action research should be considered from different perspectives: as a professional approach, a body of skills that is needed to make the connection between knowing that and knowing why; and as a way of improving practice by systematically building up practice‐based knowledge.  相似文献

This article describes the complex nature of collaborative relationships, the difficulties of conducting research with others, and the complications of partnerships in educational research. To create and sustain a communicative space in which participants can collaborate to innovate education and curriculum, time and opportunity to develop trust in the group are needed. We report on a collaborative action research project in the Netherlands in which 14 teachers, three facilitators and an academic researcher formed a partnership, and together designed Language 1 education. We find contextual and the communicative conditions are important in the collaborative action research partnership. We use metaphors of facilitative actions – map, magnifying glass, mirror and compass – formulated by Wadsworth to analyze and describe the collaboration. We show that the participants had to come to terms with their roles and responsibilities and, through dialogue and reflection, evolved and learned to contribute to the collaborative action research partnership by sustaining dialogue and utilizing their unique expertise.  相似文献

Both cognitive and sociocultural traditions have customarily theorised learning in terms of processes of progression within single communities. More recently, educational scholars have started to focus on learning as a horizontal process of boundary crossing between multiple communities. A problem of this approach is that boundaries are often laid out analytically on a system level, without explaining whether and how boundaries relate to discontinuities at the level of an individual student's learning process. The latter requires theoretical elaboration on how an individual learner can, simultaneously, be part of more than one practice. By drawing on a dialogical approach to self, we intend to theorise learners as participants in practices, and as transcendent selves. In doing so, we point out that boundaries are dynamically evolving discontinuities that mediate or obstruct potential hybridisations of school and everyday life experiences in learning.  相似文献

The prevalence of child maltreatment in the Netherlands was in 2005 first systematically examined in the Netherlands’ Prevalence study on Maltreatment of children and youth (NPM-2005), using sentinel reports and substantiated CPS cases, and in the Pupils on Abuse study (PoA-2005), using high school students’ self-report. In this second National Prevalence study on Maltreatment (NPM-2010), we used the same three methods to examine the prevalence of child maltreatment in 2010, enabling a cross-time comparison of the prevalence of child maltreatment in the Netherlands. First, 1,127 professionals from various occupational branches (sentinels) reported each child for whom they suspected child maltreatment during a period of three months. Second, we included 22,661 substantiated cases reported in 2010 to the Dutch Child Protective Services. Third, 1,920 high school students aged 12–17 years filled out a questionnaire on their experiences of maltreatment in 2010. The overall prevalence of child maltreatment in the Netherlands in 2010 was 33.8 per 1,000 children based on the combined sentinel and CPS reports and 99.4 per 1,000 adolescents based on self-report. Major risk factors for child maltreatment were parental low education, immigrant status, unemployment, and single parenthood. We found a large increase in CPS-reports, whereas prevalence rates based on sentinel and self-report did not change between 2005 and 2010. Based on these findings a likely conclusion is that the actual number of maltreated children has not increased from 2005 to 2010, but that professionals have become more aware of child maltreatment, and more likely to report cases to CPS.  相似文献

This paper explores the challenges of using the Toulmin model to analyze students’ dialogical argumentation. The paper presents a theoretical exposition of what is involved in an empirical study of real dialogic argumentation. Dialogic argumentation embodies dialectical features — i.e. the features that are operative when students collaboratively manage disagreement by providing arguments and engaging critically with the arguments provided by others. The paper argues that while dialectical features cannot readily be understood from a Toulminian perspective, it appears that an investigation of them is a prerequisite for conducting Toulminian analysis. This claim is substantiated by a detailed review of five of the ten most significant papers on students’ argumentation in science education. This leads to the surprising notion that empirical studies in the argumentation strand — even those studies that have employed non-dialectical frameworks such as the Toulmin model — have implicitly struggled to come to terms with the dialectical features of students’ discourse. The paper finally explores how some scholars have worked to attend directly to these dialectical features; and it presents five key issues that need to be addressed in a continued scholarly discussion.  相似文献

Outcome-oriented evaluation of school effectiveness is often based on student test scores in certain critical examinations. This study provides another method of evaluation—value-added—which is based on student achievement progress. This paper introduces the method of estimating the value-added score of schools in multi-level models. Based on longitudinal student achievement data, two measures of school effectiveness in one local education authority in China are compared. It is found that the between-school difference in both test-score and value-added is large comparable with that of Western countries. The results of the two measures of school effectiveness are highly different. The value-added measures lack consistency across different subject areas within schools while the test score measures are highly correlated between subjects. Teachers show their preference for value-added measures over test-score measures of education quality. It is suggested that value-added measures of school effectiveness should be used as a complement to rather than a substitute for test-score measures. The shortcomings of value-added approach are also discussed.  相似文献

ObjectiveThe present study examined possible explanations for symptom development and variability in sexually abused adolescents. A theoretical model of sexual abuse, in which appraisal, coping and crisis support play prominent roles, was tested in a clinical group of 100 sexually abused adolescents.MethodParticipants, aged 12–18 years, completed questionnaires regarding severity of abuse, negative appraisals, crisis support, coping strategies, and trauma-related stress symptoms.ResultsSince severity of abuse had no influence on the association between appraisals and symptoms it was eliminated from our model. Structural equation modeling analyses showed a significant interrelationship between the examined concepts. Adolescents who appraised the abuse as more threatening showed more internalizing and externalizing trauma symptoms. Moreover, more negative appraisals were associated with more avoidance as well as with more active coping strategies. Direct crisis support was associated with less negative appraisals and with the use of more active coping strategies.ConclusionsThe study showed that especially the buffering role of crisis support and the role of negative appraisals explained symptom development and variety in sexually abused adolescents.Practice implicationsAdaptation to sexual abuse includes the ways in which adolescents perceive the event as threatening and harmful, how they cope with the abusive experience, and how they receive direct support from their family. Clinicians, therefore, need to expand the focus of their assessments beyond age- and trauma-specific symptoms, to age- and trauma-specific appraisals, coping, and social support. The assessment of these factors should take place as soon as possible after the disclosure of the abuse. Individualized treatment plans and clinical interventions need to be based on these personal and environmental variables, rather than reliance on the influence of abuse-related characteristics, such as the severity or type of abuse.  相似文献

ObjectiveThe expansion of Home Visitation Programs for at-risk, first-time mothers and their young children has drawn attention to the potential impact of depression on program outcomes, yet little research has examined depression in the context of home visitation. The purpose of this study was to determine the prevalence of and changes in depressive symptoms in mothers enrolled in home visitation and identify predictors of change in symptoms over the first 9 months of service.MethodsSubjects consisted of 806 at-risk, first-time mothers enrolled in a Home Visitation Program. Self-reported depression was measured at enrollment and again 9 months later. Established clinical cutoffs were used to identify clinically elevated levels of depression. Additional measures were taken of interpersonal trauma history, concurrent intimate partner violence, and social support.ResultsResults indicated that: (1) 45.3% of mothers had clinically elevated symptoms of depression at some point during the first 9 months of service, (2) 25.9% of mothers had elevated symptoms at both time points or at the 9-month assessment, and (3) 74.1% experienced an interpersonal trauma prior to enrollment. Lack of improvement or worsening of depressive symptoms from enrollment to 9 months was best predicted by pre-enrollment interpersonal trauma history, young maternal age, being African American, and symptoms severe enough to have led to mental health treatment.ConclusionsFindings suggest that maternal depressive symptoms are a significant problem in home visitation. The role of interpersonal trauma in depressive symptoms, and how to best address these clinical issues in home visitation, warrants further examination.Practice implicationsMaternal depression is prevalent in Home Visitation Programs, and many mothers exhibit elevated symptoms at multiple time points over the first year of service. Interpersonal trauma history is also prevalent, and is predictive of increased depressive symptoms over time. Home Visitation Programs should note that mothers with interpersonal trauma history, young maternal age, and being African American have an increased likelihood of persistent depressive symptoms, which may in turn pose significant challenges to providing services.  相似文献
