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

Framing this essay as a preface to a return to the field in order to collect more data for her study of the older, white southern women of her hometown, this researcher uses Laurel Richardson's (1994) concept of ''writing as a method of inquiry'' in order to revisit some of the places in which she has already done field work. By employing Deleuze and Guattari's (1980 1987) image of the nomad deterritorializing space, she revisits some of those spaces- mental space, the space of the text, and the space of theory- in order to work out of the failure of her received understanding of fieldwork and to think differently about the spaces and places in which her research takes place. 相似文献

Although creativity and expertise are related, they are nonetheless very different things. Expertise does not usually require creativity, but creativity generally does require a certain level of expertise. There are similarities in the relationships of both expertise and creativity to domains, however. Research has shown that just as expertise in one domain does not predict expertise in other, unrelated domains, creativity in one domain does not predict creativity in other, unrelated domains. People may be expert, and people may be creative, in many domains, or they may be expert, or creative, in few domains or none at all, and one cannot simply transfer expertise, or creativity, from one domain to another, unrelated domain. The domain specificity of creativity matters crucially for creativity training, creativity assessment, creativity research, and creativity theory. The domain specificity of creativity also means that interdisciplinary thinking, interdisciplinary collaboration, and interdisciplinary creativity are even more important than one would assume if creativity were domain general. 相似文献
