One of the aims of science education is that students should be able to apply scientific principles to contemporary issues. Individual interviews were used to investigate the way in which students (63 12-year-olds and 60 16-year-olds) applied the ecological concept of interdependence of species to the issue of preservation of species. Students were shown a list of items representing a range of living things and were asked to select those which they would want to save from extinction and explain their reasoning. Although most students used the concept of interdependence for some items, they did not apply it in a scientifically consistent way to all types of living things. Three probable reasons for this lack of consistency were anthropocentricism, mixed reasons (students appeared to spontaneously choose another type of reason depending on what image the item immediately provoked), and opposite reasons (students interpreted the idea of interdependence as applying to some types of living things but not to others).

Cowboy boots are some of the most recognizable dress icons in the United States and symbolize the American West. The mythology of these material culture objects has been built over hundreds of years in many types of oral and written narratives. The purpose of this study was to combine secondary sources focusing on specific dimensions of cowboy boots with interviews of bootmakers and firm owners, developing a clearer understanding of the multicultural evolution of this material culture icon. Results indicate that although most bootmakers are aware of the multicultural origins of cowboy boots, they do not possess a complete comprehension of the origins and development of this material culture icon. 相似文献

Increasingly, the long‐term success of a company resides in its ability to develop and market successful new products in a cost‐and time‐effective manner. In general, Japanese companies have outperformed their Western counterparts in bringing new products to market over the last 10 to 20 years. This has given them a substantial advantage in long‐term economic development. The authors hypothesize that the differences between the dominant models of corporate culture in Japan and the U.S. account for the Japanese advantage. In comparison to U.S. companies, Japanese companies tend to emphasize long‐term leadership, decentralized decision making, a flatter work structure using cross‐functional work teams, and rewarding teams for the ability to learn from mistakes. As a result of these differences, Western companies are more likely to utilize “single, loop” learning, where new products are developed using established (and unquestioned) procedures. Conversely, Japanese companies rely on “double‐loop” or “deutero” learning styles, which encourage employees to leverage their past experiences when proposing new product innovations. The authors conclude by outlining a research program for testing their as‐gumptions about the relations among nationality, corporate culture, learning styles, and new product success. 相似文献

The discriminant validity of the Upper Preschool Level of the Differential Ability Scales (DAS) was studied using 32 at‐risk preschoolers (females = 14, males = 18) with a mean age of 57.28 months (SD = 4.43) and 30 normal preschoolers (females = 13, males = 17) with a mean age of 56.40 months (SD = 6.46). The results indicated that the DAS was an excellent measure to use when trying to differentiate between at‐risk and normal preschoolers. The DAS could reliably identify, better than chance, whether a child was at‐risk or normal. Specifically, the General Conceptual Ability score was found to be approximately 77% accurate in correctly classifying at‐risk from normal preschoolers. In addition, the use of the DAS in an abbreviated format by selecting specific core and/or diagnostic subtests during the preschool screening process was strongly supported. © 1999 John Wiley & Sons, Inc. 相似文献

It comes as no surprise that persons in leadership roles face many decisions related to providing distance learning experiences, especially ones centered on the Internet. In this paper we will try to focus upon leadership issues that arose during the creation and offering of an Internet-based course for high school chemistry teachers. One of us served as the department chair, another as the professor of record and course designer, and the third as a researcher who developed a systematic case study of the course. 相似文献

If school counseling is to be a career commitment, not a temporary or occasional assignment, the school counselor must possess some special expertise that enables him to make a unique contribution to the school. It follows that counselor educators should identify this special expertise as precisely as possible and then offer an instructional program designed to develop it. Since such special expertise is not likely to be acquired without extensive and intensive training, the instructional program will ordinarily require a minimum of two years of full-time study. This position paper elaborates the rationale for the above beliefs and attempts to suggest directions in which they may lead. 相似文献
