Time sampling: a methodological critique   总被引:5,自引:0,他引:5  
Numerous developmental studies of social behavior employ an observational technique called time sampling. This technique is used to estimate the frequencies and proportions of time that actual behaviors occur and to measure group or individual differences. By contrasting time sampling to continuous sampling, we demonstrate that (a) time sampling is inaccurate for estimating actual durations or frequencies of behavior, and (b) resulting individual and/or group differences can change depending on whether time sampling or continuous sampling is used. Error rates are particularly high when the total bout lengths of the actual behaviors are short (as in mother-infant interactions) and/or when interval length is long. Because the majority of mother and infant behaviors are short in bout length (less than 60 sec), when percent error is the greatest, we suggest that alternative sampling methods that have proven validity be used in future studies (e.g., scan, point, or continuous sampling).  相似文献

“Back‐to‐basics” policies fit easily within many mathematics classrooms. Features such as order, control, rule following, uniformity, and conformity are relatively commonplace and are now more generally in demand with the current political backlash against progressive forms of schooling. This paper examines some of the influences of these traditional features of classrooms through a case study of one mathematics department in the United Kingdom. Interviews with students, lesson observations, results of questionnaires, and other case study data are analysed to show the ways in which traditional forms of learning can inhibit understanding, reify the divide between school and the “real world,” and suppress the transfer of knowledge. The findings suggest that two key elements of British Conservative education policy the commitment to traditional forms of schooling and the drive to produce school leavers capable of adapting to the demands of the 21st century — are fundamentally in conflict.  相似文献

This paper acknowledges that, in many contexts, the term ‘education for the environment’ has generated powerful images which have resonated with educators seeking empowerment for themselves and their students. We also acknowledge that it has enabled inquiry into socio‐political dimensions of environmental issues. However, we propose that this term has become a slogan and, as such, its use has been insufficiently problematised. We identify anomalies and inconsistencies associated with the use of ‘education for the environment.’ Further, we argue that the term is conceptually and linguistically flawed and that we may not need, or want, the structures that it imposes. In challenging, rather than casually accepting, this terminology, we seek to regenerate a fundamental dimension of the discourse within environmental education.  相似文献

There has been a continuing increase in the application of hierarchy theory to the problems of instruction and evaluation, since Gagné first used the term hierarchy in his theory of how human beings acquire complex skills and knowledge. This article, based on a 1970 symposium of the American Educational Research Association, presents an overview and analysis of the use of learning hierarchies in instruction and research, examines some current research on learning hierarchies, and considers the implications of this research for instructional psychology and for theories of cognitive development.Lauren B.

This is an era of significant government involvement in schools in England, despite consistent rhetoric from the Department of Education to the contrary. In such a period, signs can be detected of the juncture between a postmodern identity and post-professional status, two models of teacher professionalism supposed in Hargreaves’ work on the fourth age of professionalism. This paper focuses on the former as the nature of the contemporary context. Defining features of postmodernity are considered through a focus on the broad issue of teacher professionalism. For this paper, this is embodied by teachers’ involvement with the development of the Primary National Curriculum for England. Evidence will be drawn from just before its 1988 introduction until 2013 in order to critique several of the key tenets of postmodernity as identified by Hargreaves. This is of particular importance in a context where a strong defence is necessary to enable the sustainment, and growth, of teachers’ professional autonomy. This paper aims to propose some strategies teachers could enact in the face of postmodern challenges.  相似文献

Teacher effectiveness research now informs the rationale of much Australian education policy aimed at redressing student under‐achievement. The approach draws a ‘straight line’ between teacher practice and student outcomes, ‘controlling’ for and ultimately dismissive of other possible influences. The paper calls into question this conception of teaching–learning relations, particularly the extent to which teaching practice can be reasonably quantified and improvements in students' academic achievement can be solely attributed to and/or sole responsibility placed on the pedagogic strategies employed by teachers. Drawing on the theoretical resources of Foucault and Bourdieu, the paper argues further that teacher effectiveness research is flawed in both means and ends. It concludes that in its ranking of student and teacher performance, such research actually works against the purposes of education; specifically, authentic teaching and learning.  相似文献

ABSTRACT

This article examines the case for the sandwich degree as the flagship for undergraduate business education in the UK and uses a range of available, but limited, evidence to show that the history of the practical implementation of the concept is such as to undermine its credibility. The theoretical benefits of the sandwich year are not delivered in practice, especially for students. The costs to students and to the public purse appear to outweigh the alleged benefits. The article uses existing published sources to cast doubt on the wisdom of pursuing the sandwich concept but concludes that available evidence is sketchy and inconclusive. Further research is planned at Bolton Business School to identify the impact of the business studies graduate on the labour market and alternative models for the development of business and personal competencies.  相似文献

ABSTRACT The concepts of experience and experiential learning are of critical significance in both the study and practice of adult education. Adults are seen as uniquely characterised by their experience, experiential learning an alternative to didactic and knowledge-based modes of education. In this paper a critique is presented of the powerful discourse of the autonomous subject based on humanistic psychology which, it is argued, has shaped adult education in a misleading, inappropriate and unhelpful way. A postmodern perspective drawing on Continental philosophy is utilised. The 'situated' subject provides a conception of subjectivity and experience which preserves a needed dimension of agency whilst avoiding psychologism and individualism.  相似文献

Contemporary health education and promotion programmes are criticised for their confused and equivocal value positions. Where any recognisably distinct moral stance is discernible in current approaches, this is typically supported by an appeal to some form of individualistic ethics which has its roots in the traditional medical model of health and illness. It is argued that value‐neutral and information based strategies should be replaced by programmes with clearly articulated and rationally supported value foundations. The hidden curriculum of individualism in health education is attacked on the grounds that it fails to acknowledge the structural inequalities in society which effectively determine the health of individuals. In its place a social model of practice, incorporating an analysis of the socio‐economic determinants of health and illness, is recommended, and this is supported by appeals to utilitarian ethics and to social morality and justice.  相似文献

This paper attempts to examine critically evaluation studies concerned with the implementation of Reading Recovery, an intensive individualised early intervention programme, by focusing on teacher, child and systemic change. Some conceptual and methodological shortcomings which have characterised many evaluations to date are discussed, together with ways in which these weaknesses could be redressed in future studies.  相似文献

The ascendant model of the school in the specialist administrative and organisational literature is the ‘loosely coupled’ system. There are, however, ambiguities in the way this model has been applied, whether as a research tool or as a theoretical device to mark out institutions such as hospitals, schools and prisons where the elements of functional analysis (goals, technology, structure) have no predictive interdependence. The irony that a model which derives from biological and cybernetic thinking should become a tool of demystification of orthodox functional theory is interesting in itself and perhaps points to a major conceptual weakness in its formulation and application. It is argued that ambiguities in the model can be addressed by a structuralist approach which distinguishes the surface features of looseness from the more determining patterns of the inter‐relationship between rules and rituals within either the institutional or the technical ‘core’ of school organisation.  相似文献

In mathematics education literature the term hierarchy is used in a number of ways. It is important that the mathematics educator consider the usefulness of the hierarchies presented by various researchers and theorists, in the light of their application to teaching. Current works on mathematical learning hierarchies are illustrated and in particular the work of the mathematics team of the research project Concepts in Secondary Mathematics and Science is examined.  相似文献
