This paper addresses the parallel between the changes in students' and teachers' learning advocated by constructivist science educators. It begins with a summary of the epistemology of constructivism and uses a vignette drawn from a set of case studies to explore the impact of a constructivist science in‐service programme on an experienced and formal elementary science teacher. Judged by constructivist standards, the teacher described in the vignette makes very little progress. The irony of applying a constructivist critique to his work, however, is that it fails to treat the teachers' imperfect knowledge of teaching with the same respect as constructivists treat students' imperfect learning of science. The remainder of the paper explores this constructivist paradox, and suggests that‐like students' knowledge of science‐teachers' knowledge of constructivist science teaching is likely to grow through slow and gradual re‐formation of their established understanding of classroom theory and practice. 相似文献

ABSTRACT This paper considers the examination results of TVEI and non TVEI pupils in the database established at the University of Newcastle in 1985‐87. The pupils took national exams in the summer of 1987, when they were about 16 years old. Their average grades (Exam Means) and their accumulated grades (Exam Totals) were considered separately. The Exam Mean and Exam Total scores were generally worse for TVEI than non TVEI pupils, even when pupils with the same ability test scores and aspirational scores were compared. However, it is possible that non TVEI factors caused the discrepancy in results and it is these factors which are the subjects of this paper. The paper considers firstly whether the differences are an artefact of regression analysis. Secondly, the data are considered using various multilevel models. Both analyses suggest that there was no TVEI effect on the Exam Mean score and a negative TVEI effect on the Exam Total. Various explanations for these findings, concerning internal school allocational and curriculum policies, are considered and discussed. 相似文献

Abstract Correspondence study represents the first and most persistent distance education format in American universities. Later called independent study, it enabled universities to disseminate instruction far beyond their campuses. Yet, national‐level leadership provided by the National University Continuing Education Association (NUEA) and its divisions has been relatively restrained. In contrast, leadership in the private correspondence school sector has been assertive, and sometimes even aggressive. The NUEA and its members shunned this approach, choosing instead to lead by persuasion and example. The NUEA developed standards of practice concerned primarily with replicating on‐campus teaching styles and values, rather than the promotion of distance education. With the abolition of its division structure, the NUEA's successor, the University Continuing Education Association (UCEA), has opted out of a leadership role in independent study. This paper concludes that the NUEA's initial attempt at leadership in distance education— while reasoned and principled—contained flaws that made failure inevitable. 相似文献

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed. 相似文献
