Although Boudon’s distinction between primary and secondary effects, and its associated rational action models of inequality of educational opportunity, have been more influential in the field of social stratification and mobility than in the sociology of education, there is good reason to reconsider the theoretical and practical implications of this approach. The investigation brings conceptual analysis and empirical research to bear on Boudon’s arguments in a manner that may be somewhat unorthodox. The theoretical arguments are developed in the context of a detailed empirical investigation of three transitions—age 10 to O‐level, O‐level to A‐level, and A‐level to degree—using the extensive 1970 British Cohort Study. It is concluded that primary and secondary effects should be recognised as methodological rather than theoretical concepts, that the techniques used to identify them are independent of rational action theory and that, contrary to an influential position, the evidence suggests that primary effects are more important than secondary effects in the generation of social disparities in access to education 相似文献

Given the rapidly changing skills needs of ‘post‐industrial economies’, lifelong learning forms an integral part of government policy within the UK and abroad. However, like the UK, most economies are faced with the problem of how to reach those sections of the community that have traditionally not embraced learning and educational opportunities. In this paper, the development and evaluation of a system designed to address this problem is described. The Lifelong Learning in London for All (L4All) project has investigated the concept of ‘trails’ as a way of organising lifelong learning opportunities. The L4All pilot system combines a set of web services to provide the functionality needed to support this central idea. The development process was outlined, and the findings of an empirical study were used to confirm proof of concept. 相似文献

Interdisciplinary Learning: Process and Outcomes 总被引:1,自引:0,他引:1
Lana Ivanitskaya Deborah Clark George Montgomery Ronald Primeau 《Innovative Higher Education》2002,27(2):95-111
Interdisciplinary learning is characterized by the integration of multidisciplinary knowledge across a central program theme or focus. With repeated exposure to interdisciplinary thought, learners develop more advanced epistemological beliefs, enhanced critical thinking ability and metacognitive skills, and an understanding of the relations among perspectives derived from different disciplines. Our adaptation of Biggs and Collis' (1982) Structure of the Observed Learning Outcome illustrates the stages of interdisciplinary knowledge integration and explains corresponding patterns of learners' intellectual functioning, from acquisition of single-subject information to transfer of interdisciplinary knowledge to other topics, issues, or problems. 相似文献

This paper seeks to compare the traditional delivery of introductory courses in business statistics within a business and management faculty, with that of an approach that seeks to teach through information technology (IT). To achieve this objective this paper will examine how traditionally taught courses in business statistics are delivered and compare this with a teaching approach through the use of IT 相似文献

The relationship between intellective and non-intellective variables and counseling competence was investigated by comparing student counselors rated as falling within the top 25 percent in overall competence at the end of an evaluation seminar with their counterparts rated in the bottom 25 percent. Competence was operationally defined as a composite of knowledge of counseling theories and techniques, knowledge of and ability to use test data in counseling, and counseling skill. Significant differences between the high-rated and low-rated student counselors were observed on the dimension of chronological age, five of six intellective variables, and five of 11 non-intellective variables. 相似文献

Contributing factors to long‐term citation count in marine and freshwater biology articles

Researchers have investigated factors thought to affect the total number of citations in various academic disciplines, and some general trends have emerged. However, there are still limited data for many fields, including aquatic sciences. Using papers published in 2003–2005 (n = 785), we investigated marine and freshwater biology articles to identify factors that may contribute to the probability of citation and for cumulative citation counts over 10 years. We found no relationships with probability of citation; however, we found evidence that for those that were cited at least once, cumulative citations were related to several factors. Articles cited by books received more citations than those never cited by books, which we hypothesized to be indicative of the impact an article may have in the field. We also found that articles first cited within 2 years of publication received more cumulative citations than those first cited after 2 years. We found no evidence that self‐citation (as the first citation) had a significant effect on total citations. Our findings were compared with previous studies in other disciplines, and it was found that aquatic science citation patterns are comparable to fields in science and technology but less so to humanities and social sciences. 相似文献
