Two studies are reported describing the development and validation of the Strategic Flexibility Questionnaire (SFQ): a self-report instrument aimed at eliciting students’ beliefs about the need for, and conditional nature of, self-regulatory control over learning. In Study 1, 281 first-year university education students completed a 40-item pilot questionnaire. Factor analysis of responses revealed a 21-item instrument indicating three types of control beliefs: adaptive executive control, inflexible executive control, and irresolute executive control. In Study 2, the predictive validity of these conceptions was tested against the academic performance of 105 third-year university education students. Results indicated that students reporting adaptive executive control beliefs were more successful academically, while those students reporting inflexible or irresolute control beliefs were significantly less successful academically.  相似文献

Metaphor and Totem: Exploring and evaluating prior experiential learning   总被引:3,自引:3,他引:0  
The evaluation and recognition of prior experiential learning is now well established. A significant issue in such evaluations has been the centrality of the learner and his/her empowerment in the educational process. However, most models of evaluation require equivalency between the unique experiences of the subject and existing course analogues. In these models evaluation is based on metaphor, on finding varying degrees of similarity between the experience being assessed and currently existing academic structures. The present paper calls for a richer perspective to be taken in assessing prior experiential learning with particular interest being seen in the notion of totemism as characterised by anthropologist Claude Levi-Strauss. A replacement of metaphor by totemism may restore power, ownership and centrality of the experience to the candidate for assessment, while allowing evaluators an opportunity to engage in a novel but authentic articulation of the underlying academic equivalency of the experience.  相似文献

This study examined the cost and performance of six commercial document suppliers accessible via OCLC, and comapared their service to that of traditional interlibrary loan (ILL). Results indicated that, while commercial firms cannot be recommended as a wholesale replacement for ILL, they can add much-needed flexibility to a library's overall plan for document delivery.  相似文献

The authors report on a self‐completed questionnaire study from a North Yorkshire based general practice regarding the information needs of its clinicians. The work was carried out with a particular focus on the practice library, and the findings identified that a new approach to maintaining and developing the library was needed. The literature regarding the information needs of primary care clinicians and the role of practice libraries is considered, and compared to those of the clinicians at the practice. Discussion follows on how a collaborative project was set up between the practice and a librarian based at the local NHS Trust library in order to improve the existing practice library. Difficulties encountered and issues unique to the project are explored, including training implications presented by the implementation of electronic resources. Marketing activities implemented are discussed, how the library will operate in its new capacity, and how ongoing support and maintenance of the library will be carried out. It is concluded that although scepticism still exists regarding librarian involvement in practice libraries, collaboration between clinicians and librarians is an effective approach to the successful development and maintenance of a practice library, and recommendations are therefore made for similar collaborative work.  相似文献
