This article, based upon the field of comparative didactics, seeks to contribute to the identification of generic and specific features in the teaching and learning process. More particularly, its aim was to examine, through the study of two different school subjects: biology and English as a second language, how passive didactic differentiation can develop and account for the gap in progress growing between more-able and less-able students. For our analysis, we adopt a didactic viewpoint basing our study on what is going on in the class when the teacher and her students interact and use notions borrowed from the Joint Action Theory in Didactics. At the end of the article, we mainly argue that more teacher training focused on ‘objects of learning’ and ‘knowledge-in-use’ is necessary if we want teachers to be able to produce didactic milieus adapted to students with mixed abilities and, more generally, if we want to increase epistemic access.  相似文献

Inclusive education as a global movement emerged over the past 30 years to ensure quality mainstream education for all learners. Since 1994 the newly democratic South Africa also had expectations as well as the political will to change education by adjusting legislation and policies. However, the vision of a truly inclusive education system in South Africa has been difficult to achieve and results regarding the implementation of inclusive education remain questionable. There has been a growing realisation that the advent of democracy was not in itself a sufficient condition for the elimination of historical and structural inequalities in education with as recurring theme the dissonance between the government's socio-political imperative for change and economic realities. This article focuses on the development of policy and guidelines on inclusive education in dynamic interaction with the complexity of realities in South African schools with a special focus on the policy recommendations regarding the development of full-service schools. The constant comparative analysis of the two phased case study of a full-service school in a rural town revealed interesting results illustrating the complexities regarding the implementation of inclusive education and the challenges and opportunities in bridging the gap between the idealism of policies and the realities in schools.  相似文献

Abstract

Purpose: To identify and review production and marketing information sources and flows for smallholder cashew (Anacardium occidentale L.) growers in Tanzania and recommend systems improvements for better technology uptake.

Design/methodology/approach: Two-stage purposive samples were drawn. First, two districts in the main cashew producing areas, one with significant research investment and good marketing infrastructure and the other a counterfactual. Second, two villages were purposively selected from each district to provide the maximum contrast of variables pertinent to the study. Field data were collected using a semi-structured, open-ended questionnaire complimented by field verification and a wrap-up stakeholders' workshop. The data were analysed using chi-square test and the orderly probit model.

Findings: Sources of information and flows varied between districts and villages. For production, the most reliable sources were role model farmers (RMFs), extensionists, radio, on-farm demonstrations, researchers, cashew development centres (CDCs), print media and mobile phones in order of popularity. RMFs, radio programmes, extensionists, interactions with researchers, CDCs and print were the main pathways. For marketing, primary society notice boards, radio announcements, RMFs, extensionists, mobile phones and print were listed in order of popularity. Print media was the least popular due to a low level of literacy among growers. RMFs were popular actors in the information systems irrespective of social-economic background.

Practical implications: Policy change and additional resources are required for improvement of existing information systems. Additionally, incentive structures that will enhance and sustain continued investment in cashew production should be emphasized.

Originality and value: This is the first attempt in the Tanzanian cashew sector to analyse and link social economics of growers with information sources, communication channels and technology uptake.  相似文献

The Future Voices in Public Services column is a forum for students in graduate library and information science programs to discuss key issues they see in academic library public services, to envision what they feel librarians in public service have to offer to academia, to tell us of their visions for the profession, or to tell us of research that is going on in library schools. We hope to provide fresh perspectives from those entering our field, in both the United States and other countries. Interested faculty of graduate library and information science programs, who would like their students' ideas represented in these pages, are invited to contact Nancy H. Dewald at nxd7@psu.edu.

Brigitte Burris is a graduate student at Drexel University's iSchool and also works as a librarian at the University of Pennsylvania. At a time when many librarians hope for the expansion of open access to scholarly resources, Burris here proposes a method of adding attributes to articles in institutional repositories in order to increase faculty members' incentive for depositing their scholarly articles.

The iSchool at Drexel's Master of Science in Library and Information Science, MS(LIS), is the second oldest program of its kind in the nation, and one of just 56 ALA-accredited programs. More technologically oriented than other programs, the MS(LIS) prepares graduates for a wide variety of positions including academic librarian, knowledge management specialist, systems librarian, digital librarian, Web developer, and competitive intelligence analyst. The 2009 edition of U.S. News & World Report's “America's Best Graduate Schools” rated the MS(LIS) program 11th in the nation overall, with specialties in information systems and digital librarianship ranking fifth and sixth, respectively. The iSchool at Drexel's faculty has been nationally recognized, ranked by Academic Analytics, a third party company benchmarking academic excellence, as 8th in the nation for scholarly productivity.  相似文献

Symbolic violence may not be a desirable theory to apply to public schooling—its structuralist limitations render it deterministic, lacking in human agency, and unpalatable to researchers and educators who see schools as viable and productive sites of social transformation. Perhaps for these reasons, it seems little has been written about symbolic violence in schools, and what has been written tends to focus primarily on the symbolic, institutionalized violence imparted by schools and teachers upon students. In this article, I offer a shift in these perspectives. I present symbolic violence as a productive analytical tool in identifying modes of resistance to specific damaging effects of schooling institutions. I also illustrate how symbolic violence victimizes one particularly caring teacher, rendering her compliant in her own victimization, without voice to accurately name her struggles, and—because of her ethic of care—complicit in reproducing damaging institutionalizing practices. Using ethnographic data, I explore symbolic violence via one teacher's reflective, critical narratives. I draw upon the tenets of dialogicality in language to help make more visible the often intangible elements of symbolic violence. And at various points in the article, I discuss the implications of engaging an analytic that ultimately runs counter to my own epistemology, turning to Maxine Greene for insight in the struggle.  相似文献

This article reports on an action research project in which the value of critical friendship for students doing research and writing their dissertations within an international master’s course has been explored. This course is run jointly by Roehampton University (London, UK), Charles University (Prague, Czech Republic) together with Fontys OSO (Tilburg, the Netherlands). It describes the process and the results of working with the concept of critical friendship in this master’s course since its start in 2005. Data were collected by means of various qualitative instruments and data sources: evaluation forms after tutorial sessions, reflective logs and focus interviews. The results show that the process of engaging with the research they did was enhanced and supported by the development of critical friendship groups. A number of recommendations have been formulated, such as the importance of discussing the concept of critical friend and its philosophy with the participants and of defining roles and tasks as clearly as possible.  相似文献

In recent experiments in which the social influences on feeding in Mongolian gerbils were investigated, observer gerbils acquired food preferences from conspecific demonstrators only if the demonstrators and observers were either related or familiar. Even then, the effects of demonstrator gerbils on observers’ food choices lasted less than 24 h. In similar experiments with Norway rats, the familiarity/relatedness of demonstrators and observers had little effect on social learning, and the demonstrators’ influence on observers’ food choices lasted many days. We examined the causes of these differences and found that, after observer gerbils interacted with either unfamiliar or familiar conspecific demonstrators that had been fed using procedures typically used to feed demonstrator rats, they showed long-lasting social learning about foods, whereas observer rats interacting with conspecific demonstrators that had been fed as demonstrator gerbils normally are fed showed effects of familiarity/relatedness to demonstrators on their social learning about foods. Procedural differences, rather than species differences, seem to be responsible for reported inconsistencies in social learning about foods by rats and gerbils.  相似文献

The purpose of this study was to measure alterations in sensorimotor skills and balance resulting from slackline training and conventional balance training. Forty-three physically fit subjects were randomized into three groups. Two groups practiced three times a week for 15?minutes, including at least once supervised session, on the slackline or perform conventional balance training for 6 weeks. The control group was not allowed to perform any balance training. Before and after the intervention, the subjects underwent sensorimotor and strength tests. The results of our intra-class correlation analysis showed that the stability parameters from the multifunctional training device (MFT, 0.7), the height during the countermovement jump (CMJ, 0.95) and the maximum force (0.88) during leg press showed excellent reliability. A post hoc comparison indicated a larger effect of conventional training (almost 11% reduction in MFT stability) compared with slackline training in group-wide comparisons of the pre- to the post-training measurements. The factor analysis showed that stability and sensorimotor assessment using MFT were correlated, as were height during CMJ and maximal force during leg press, which represented dynamic strength. Because CMJ had the highest intra-class correlation value, it was chosen over maximum force from leg press. For these reasons, only two out of nine measured parameters, namely MFT stability and CMJ, were analysed across groups. The only observed difference between the two groups was MFT stability (slackline???1.5%, conventional???13%), whereas the improvement of CMJ was the same (slackline?+?3%, conventional?+?3%). It can be concluded that slacklining is partly complementary to conventional sensorimotor training.  相似文献

OBJECTIVE: To determine the demographic and psychosocial correlates of physical and sexual abuse among children with autism. METHODS: Data collected from 1997 to 2000 through the national evaluation of the Comprehensive Community Mental Health Services for Children and their Families Program on 156 children with autism were used. Data included a baseline assessment of child and family psychosocial experiences and presenting problems associated with referral into system-of-care service, demographic information, and a clinical record review to obtain psychiatric diagnosis. Binary and multinomial logistic regression was used to determine the association of different characteristics of children who were abused compared with those who were not abused. RESULTS: Caregivers reported that 18.5% of children with autism had been physically abused and 16.6% had been sexually abused. Physically abused children more likely had engaged in sexual acting out or abusive behavior, had made a suicide attempt, or had conduct-related or academic problems. Sexually abused children more likely had engaged in sexual acting out or abusive behavior, suicidal or other self-injurious behavior, had run away from home, or had a psychiatric hospitalization. In adjusted multivariate models, the relationship between sexual abuse and sexual acting out, running away from home and suicidal attempts persisted. CONCLUSION: Based on the prevalence of abuse and its association with various behaviors, clinicians should be as attuned to the psychosocial histories of children with autism as they are for other children, and consider the potential of abuse when these behaviors are observed.  相似文献

Assessment of students’ communication skills after a course in counselling, in which the students are prepared for work practice, requires another assessment method than the traditional written examination. In this paper we describe the construction and evaluation of simulations. The results of an investigation into the quality of the simulations show that they enable objective assessment of students’ mastery of skills in the situation which is simulated. In order to achieve generalisable scores, i.e. scores which indicate how well a student will perform in counselling interviews in general, more than one simulation has to be administered. Although the simulation is not an efficient instrument, its benefits are high: weaknesses in students’ performances will be detected so that remedial teaching can be offered, and clinical practice can be preserved for counsellors with a less than sufficient ability in counselling skills  相似文献
