This study examines the influence of the opportunity costs of school attendance, educational quality attributes, and household socioeconomic status on the educational demand of Mexican Americans, African Americans, and non-Hispanic whites using the 1988–1990 surveys of the National Education Longitudinal Study. Implementing a utility-maximizing framework, educational demand assumes the form of schools' average daily attendance rates and student dropout decisions between the 8th and 10th grades. The basic results suggest that a school's attendance rate is sensitive to educational quality and student characteristics. Moreover, the demand for education measured by student attrition inversely relates to unexplained school attendance, and is positively affected by household socioeconomic status. Some policy recommendations based on the results are discussed. 相似文献

Analogical reasoning is increasingly recognized as an important instrument for promoting conceptual change in science learning. This study characterized students' and physicians' spontaneous use of analogies in reasoning about concepts related to the mechanical properties of cardiovascular physiology. The analogies were made in response to questions at different levels of abstraction from basic physiology to clinical problems. The results indicate that analogies generated by subjects facilitated explanations in a number of ways. These include creating coherent representations in novel situations, bridging gaps in understanding, and triggering associations which result in modified explanations. Subjects at different levels of expertise used analogies differently. The more expert subjects used analogies to facilitate articulation and communication; that is, to illustrate and expand on their explanations. Novices and advanced medical students used more between‐domain analogies to explain all categories of questions. This is less evident in physicians' responses to pathophysiological and clinical problems. The paper discusses ways in which analogies can be used productively, and identifies factors that can lead to a counter‐productive use of analogies resulting in misconceptions and erroneous explanations. 相似文献

The programme of the Département de la Formation Internationale at Ecole Nationale des Ponts et Chausées (ENPC) was created in 1981 to address the ever‐increasing international role of today's engineer in the scientific, economic and social spheres. Each year, 75 ENPC students spend at least 3 months abroad, mainly in Europe. ENPC has double degree programmes in engineering studies with three European partners in Germany and Spain: TU Munich and TU Berlin; Universidad Politécnica de Madrid. Twenty per cent of the student curriculum is devoted to language study; the students are required to study English plus one of the following languages: German, Spanish, Italian, Russian, Japanese or Chinese. French courses for foreign students are also provided. Language teaching aims to provide students not only with the linguistic skills necessary for communication, but also to make them more sensitive to other cultures as well as their own. 相似文献
