Steven Higgins and Vivienne Baumfield have recently attempted to defend the much discussed idea of general thinking skills against attacks from three quarters: what they regard as a priori objections, which they liken to Zeno's paradox that Achilles will not catch the tortoise; domains theories of knowledge, which oppose the idea of thinking skills being general and transcending domains; and the claim that experts use subject specific knowledge, and don't use general thinking skills. We examine these defences and find them flawed and worrying. We conclude that this is a domain in serious need of a priori approaches. 相似文献

ABSTRACT: Food companies and supporting industries need inexpensive, revisable training methods for large numbers of hourly employees due to continuing improvements in Hazard Analysis Critical Control Point (HACCP) programs, new processing equipment, and high employee turnover. HACCP-based food safety programs have demonstrated their value by reducing the number and frequency of multimillion-dollar food recalls. The focus for the future must be proactive training of plant personnel to ensure continuous improvements in plant food safety and quality. In response to this need, we developed training modules focused on applying HACCP principles, quality aspects, and production information to individual poultry unit operations. Learning objectives were evaluated using discount usability testing techniques to optimize the delivery system and to ensure a satisfactory e-learning experience. Discount usability testing of this virtual orientation was successful in obtaining vast amounts of feedback. Usability issues with the training materials were identified. Expected completion times were not met by most participants, indicating that a change in the format of the course might be necessary, perhaps segmenting the modules into smaller sections to be reviewed independently of one another. Another suggestion by the evaluators was to include narration for the sections, which might in turn speed up the completion times. A navigation error was discovered by these users, as well as other critical errors in design. Other errors, such as font inconsistencies and page design changes, were also discovered by the participants. 相似文献

Technology education students: e-tutors for school children 总被引:1,自引:0,他引:1

E-tutoring refers to individualised learning support mediated by Internet technology. While increased demand for tutors has led to a surge in commercial e-tutoring services, volunteer e-tutoring programs for children are rare. To test the viability of volunteer e-tutoring for elementary school students, 10 undergraduate students enrolled in a technology education (TE) course provided online with instructional support to children in need of tutoring services. Each e-tutor was assigned a specific child, developed a Web Course Tools course and corresponding online activities to improve teacher-identified skill deficiencies, and provided 8 weeks of e-tutoring. Three video conferences complemented online instructional interaction between e-tutor and e-tutee. Children, parents and TE students expressed positive evaluation of the initiative. 相似文献

The anatomy of the pelvis is complex, multilayered, and its three‐dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three‐dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general‐purpose three‐dimensional segmentation and surface‐rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three‐dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory.

A focus on the interaction between cognitive schemas and context in situ has been suggested as fundamental in organizational decision making and information interpretation. Past research suggests that the situation and the social interaction that occur during learning at the cognitive level consist of factors that affect the process, but the research lacks a coherent explanation for how those factors affect it. We propose a conceptualization of learning, termed situated learning, which accounts for these factors. By drawing on situated cognition theory, social learning theory, and the theory of mental models, we identify and measure four components of situated learning, that is, thematic focus, cognitive absorption, social structure, and participation. Among the most important lessons for researchers and practitioners is the need to consider learning as a constellation of the four components instead of an indivisible phenomenon. This perspective can enhance our understanding of cognitive processes, such as information interpretation and decision making. 相似文献
