Use and abuse of corporal punishment: a Caribbean view 总被引：3，自引：0，他引：3
M A Payne 《Child abuse & neglect》1989,13(3):389-401
A sample of 499 Barbadian adults, aged 20 to 59 years, completed written questionnaires to indicate whether they generally approved or disapproved of corporal punishment in child rearing, the perceived advantages and disadvantages of such punishment, the methods and circumstances thought most appropriate for use, and those most inappropriate or ill-advised. Approximately 70% of respondents "generally approved" of corporal punishment, and three-quarters of the remainder considered it occasionally appropriate. There was evidence of considerable consensus as to what constitutes legitimate use of physical punishment and what is unsuitable and/or abusive, although certain differences in the responses of older and younger adults highlighted specific diversities of concern and shifts of attitude over time. The majority considered serious disadvantages to arise only if parents resorted to punishment in an unsystematic, excessive, or self-serving manner, although a small minority thought corporal punishment more generally undesirable or unproductive within the context of contemporary Barbadian society. 相似文献

A previous study highlighted the perception among secondary science teachers that they faced considerable challenges to their pedagogical practice when teaching unfamiliar areas of the curriculum; for example, when teaching out of subject specialism. One of the major challenges cited by the teachers was being able to give appropriate and effective science teaching explanations in the classroom. Since talking in order to explain science is at the centre of what science teachers do, this concern is a significant one for teacher educators. This article considers some of the methodological issues about how to investigate the relationship between teachers’ subject content knowledge and their pedagogical practice. The research outlined focuses on a single science teacher’s practice in giving science teaching explanations when teaching in and out of subject specialism. Although the findings from a single case are of limited value in terms of generalisability, this study adds to the discussion about future research into the relationship between teachers’ professional knowledge bases and their pedagogical practices. 相似文献

The core of the Senate Bill 2042 (1998) was designed to provide the guidelines needed to prepare teachers who can meet the needs of a diverse K-12 student population in California. Following the guidelines marked by this bill, faculty working in Teacher Credential Programs across California are designing activities to prepare candidates with a deep understanding of effective pedagogies applicable to a full range of students. A key component in this preparation is to provide teacher candidates with opportunities to critically read and reflect on theory and research. Understanding the importance of this component, I designed an assignment, Quadruple Entry Journals (QEJ), which asks teacher candidates to first, critically read texts on theory; secondly, to reflect and analyze those texts; thirdly, to reflect on the reflections of their classmates; and, finally, to connect these theoretical reflections with practice. In this article, I explain the pedagogy followed when implementing QEJ with teacher candidates. Their feedback showed that when theory and research are cooperatively analyzed by teacher candidates, they better understand the connection between theory and practice, thus creating a deep understanding of what to teach and how to teach. 相似文献

In contrast to subjects such as mathematics and the sciences, it has been argued that technology education lacks a clear definition and a clearly defined knowledge base. This discursive article seeks to inform the debate by highlighting the matter of subject definition and in addition to examine the key issue of the knowledge which underpins technology education. The nature of the knowledge involved in technology education is explored by focusing on the types of knowledge (declarative/conceptual, procedural and conditional/strategic) that are required to secure full engagement with this subject. Drawing on extant literature on knowledge, the article takes technology as its focus and highlights the challenges this presents for teachers. A conceptual framework based on the presented evidence is included to show the relationships between knowledge and the skills, the problem‐solving and the values that are integral to technology education. This article concludes that to be effective, technology teaching must be based upon an appropriate subject definition indicating what it is endeavouring to achieve. In addition the existence of such a specialist subject knowledge base must be fully acknowledged, and at the same time there must be full recognition of the need to draw upon relevant knowledge from other subject areas in an appropriate manner in order to inform classroom teaching of the subject. 相似文献

The research recounted in this paper was designed primarily to attempt to understand the reasons for the low uptake of the
natural sciences beyond compulsory education in England. This has caused widespread concern within governmental quarters,
university science departments and the scientific community as a whole. This research explored the problem from the position
of the students who recently made their choices. The student voices were heard through a series of interviews which highlighted
the complexities of the process of post-16 choice. Social theories of pedagogy and identity, such as those of Basil Bernstein,
were used in an analysis of the interview texts. Dominant themes used by the students in rationalising their post-16 subject
choice related to their past pedagogical experiences, school discourses of differentiation and the students’ notions of their
future educational and occupational pathways. This study provides no simple solutions but highlights the importance of student
voice to our understandings of what influences subject choice at this critical post-16 stage. 相似文献

In this paper the question of just who constitutes the membership of the university is explored. The paper canvasses the obvious answers: the students, the faculty, or both; the various administrators and staff above a certain level or with special responsibilities; and finally those who have passed through and out of the university doors—its old members. If to be a member is to have rights and obligations, then what if any are the obligations of the old members? This turns out to be a complex question. The analysis in the paper suggests that old members should be a third concern in our time for the universities and the pursuance of such a concern may offer many genuinely democratic supports for the university. The practical problem of how to extend the university's embrance to include its old members remains. 相似文献

In Australia, the Doctorate of Business Administration (DBA) remains a popular program but considerable anguish persists within the university sector over just what it is offering students. In this article, we use the process of postgraduate socialisation to understand how candidates, supervisors and administrators navigate pathways to successful completion and offering of a DBA program. We identify four modes of knowledge applicable to the DBA and suggest that universities and candidates may draw on one another's cultural capital to determine which mode(s) can be offered. We also illustrate how candidates exercise agency through their cultural and social capital as they move through the program. We present a conceptual framework to help guide future research, and resource allocation on the DBA. 相似文献

The increasing popularity of outdoor activities, especially hiking, indicates that people are looking for new ways to interact with the natural environment. Hiking could play a role in environmental education by exposing people to cases of environmental deterioration and so raise an awareness of environmental problems. The contribution of hiking in developing a basic understanding of the environment and its problems could result in feelings of concern that lead to active involvement in resolving environmental issues. A qualitative investigation was carried out which involved the completion of three 5 day trails by the same five subjects. Each hiker was required to make daily notes on each hike, which were subsequently analysed. The purpose of the investigation was to ascertain what people notice in the environment during hikes and whether this could influence environmental education. Four themes were identified on analysis of the daily responses, namely the natural and physical environment, trail aspects, each hiker's physical and psychological preparedness and cognitive development and social aspects ranging from group interaction to human impact on the environment. Each of these themes is described and supplemented with appropriate quotations from the daily responses. 相似文献

There are many possible reasons why students leave university prior to degree completion, and one of the more commonly cited is being employed while studying. This paper analyses the impact of employment status on dropout rates using survival analysis. It finds that employment status does have an impact on dropout rates; students who work full time alongside studying full time are less likely to complete their programme than students working short part-time or not working at all. However, it seems as if there is a threshold to how much students can work, as working more than 20?h a week (long part-time work) increase the risk of dropout as much as full-time work. Integrating employment status into the analysis does not change the effect of variables known to have an influence on dropout, such as grades, gender and social background, but it contributes to further explain who are at risk of dropout. This implies that models for dropout and retention must also take such external factors into account, not just consider what happens at university, as in model of student departure. 相似文献

This article considers the underachievement of RPL in the Australian vocational education and training (VET) system, in terms of its apparent failure to reach and achieve outcomes for marginalised groups. It notes a range of analyses that are currently used to address this concern and draws on doctoral research in progress to highlight ontological questions that are brought to the process by RPL candidates. Axel Honneth's theory of recognition is then introduced as a means to shed light on these issues. Viewing RPL through the lens of a philosophy of recognition and the concept of ontological security the article asks questions about the nature and effects of the assessor–candidate relationship, inviting consideration of this relationship as an intersubjective exchange within a wider, more fundamental ‘struggle for recognition’. It is argued that a more ontological perspective could provide a framework for increasing access to and successful completion of RPL by non-traditional learners. 相似文献

To what degree can an approach involving the use of circle time improve the quality of relationships within a class? The writers report on a piece of research they undertook involving a Year 6 class which sought to answer this question. The research was initiated because of a concern about the poor quality of relationships within the class. The writers worked together on seven weekly circle‐time sessions of 45 minutes each. There was a clear focus on relationships and the discussion of feelings. Evaluative questionnaires were given at the outset and on completion of the programme. The results were generally encouraging, in particular in terms of more positive and less negative feelings about others in the class. The authors conclude by suggesting that the reactive nature of their programme lessened its effect and emphasise the need for and value of a more proactive approach. 相似文献

Civic education is an issue of growing and serious concern. There is diminished time for civics, fewer course offerings, and gaps in students’ civic knowledge, skills, and dispositions. The role of teacher education in addressing this problem is one area deserving additional focus. This article describes the project begun by the secondary education faculty at one university to provide teacher education candidates in all content areas with the ability to address civics in meaningful ways. 相似文献

This study examined effects of food and nutrition knowledge on the self-reported behaviors of preschool teacher candidates
who completed a 10-week course. Self-reported information was gathered at entry, after completion of the course, and follow
up 4 months after completion of the course. A paired t-test compared responses at pre, post and follow up. Preschool teacher candidates improved significantly between entry and
at the end of the course for 9 of the 18 practices. Statistically significant improvements were also recorded for 13 of the
18 practices between entry and follow up. Overall, the nutrition course increased the nutrition knowledge of preschool teacher
candidates. Further analyses are needed to evaluate immediate and longer effects of nutrition course, with larger samples,
using more powerful research designs. 相似文献

Many GCSE syllabuses are examined with examinations in which all candidates take the same papers. The setting of such papers is problematic because of the wide range of abilities and achievements of pupils at the age of 16, together with the requirement that appropriate differentiation should be provided (i.e. opportunities for candidates to show what they know, understand and can do must be given). This paper considers a number of issues relevant to the setting of such examinations. These include how differentiation may be provided; the wording of questions; and how marks should be allocated. It highlights a number of potential pitfalls and concludes that although papers, which are accessible to all candidates and discriminate appropriately, can be set, common papers will not always provide adequate opportunities for the most able and least able candidates to show what they know, understand and can do. 相似文献

This exploratory study determined PhD completions at a research-intensive university in New Zealand and considered factors affecting PhD completions. Completion data were calculated for PhD cohorts at the University of Otago from 2000 to 2012 (n = 2770) and survival models determined whether gender, enrolment status, age at admission, citizenship, scholarship status and academic field influenced completion. The impact of the doctoral programme and the research environment was also considered. Across all cohorts, 83% submitted their thesis for examination (17% withdrawal). The median submission time was 3.4 years for full-timers, with a median completion time (to award of degree) of 4.1 years. Survival modelling showed that completion can be enhanced by having mainly full-time candidates, but also allowing periods of part-time enrolment near submission, recruiting a large international cohort, and providing three year scholarships. Health science candidates had the highest submission percentages, while commerce candidates submitted in the fastest times. There were only minor or negligible effects of gender and age at admission. Other factors contributing to high submission rates included recruiting quality candidates, close monitoring during candidature, provision of research training, a vibrant research culture, a personal performance coach, high-quality supervision and funding incentives for candidates who submit in under four years. 相似文献
