Analogies have been argued to be central in the process of establishing conceptual growth, making overt connections and carryover into an intended cognitive domain, and providing a generative venue for developing conceptual understanding inherent in constructivist learning. However, students' specific uses of analogies for constructing arguments are not well understood. Specifically, the results of preservice teachers' knowledge gains are not widely studied. Although we would hope that engaging preservice science teachers in exemplary lessons would assist them in using and generating analogies more expertly, it is not clear whether or how such curricula would affect their learning or teaching. This study presents an existence proof of how preservice science teachers used analogies embedded in their course materials Physics by Inquiry. This fine‐grained analysis of small group discourse revealed three distinct roles of analogies including the development of: (a) cognitive process skills, (b) scientific conceptual understanding, and (c) social contexts for problem solving. Results suggest that preservice teachers tend to overgeneralize the analogies inserted by curriculum materials, map irrelevant features of analogies into collaborative problem solving, and generate personal analogies, which counter scientific concept development. Although the authors agree with the importance of collaborative problem solving and the insertion of analogies for preservice teachers' conceptual development, we believe much more needs to be understood before teachers can be expected to construct and sustain effective learning environments that rely on using analogies expertly. Implications for teacher preparation are also discussed. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 40: 443–463, 2003 相似文献

This study traces a heuristic inquiry process from the point of view of a science educator, from a secular-humanist background in the northern United States, attempting to better understand and appreciate a major aspect of religious-influenced culture in the southern United States which has a major bearing on science education in the region. The intellectual and emotional viewpoints of selected scientists, science educators, science teachers, and prospective science teachers are examined regarding the relationship between their orthodox Christian religious beliefs and biological evolutionary theory. We view the prospect of teaching evolution to students with such a religious commitment as a prime example of the severe limitations of cognitively-oriented conceptual change theory. We also view conflicts between religion and science regarding evolution as a bona fide example of a multicultural issue in education. These theoretical perspectives are inconsistent with the common tendency among science professionals to view or treat orthodox Christian students in a manner unconscionable with others—to disrespect their intellect or belittle their motivations, to offer judgments based on stereotypes and prejudices, to ignore threats to personal selfesteem, or to deny the de facto connection of some scientific conceptions to the morals, attitudes, and values of individuals with such religious commitments. 相似文献

This is a study of an ongoing collaborative project in which science education faculty and upper elementary school teachers investigate the potential of a project-based, technologyrich, environmentally oriented approach to science education in an urban school serving a racially diverse population. Major conclusions based on the experience of participants in this study include: (1) teachers describe their instructional roles in terms highly consistent with student-centered, project-based, experiential learning; (2) teachers believe that what makes science real for students is the feeling that they are working on a truly current problem that is also being investigated by others outside their classroom. This is achieved by KidsNet, a microcomputer- and telecommunications-mediated curriculum, in a way that would not be possible without this technology; (3) teachers describe the actual and possible role of computer technology in terms which, while insightful and generally positive, are not clearly related to its flexible use in project-based learning; and (4) while teachers recognize meaningful connections between off-line science activities and the use of computer and telecommunications technologies, their students often do not.An earlier version of this paper was presented at the annual meeting of the American Educational Research Association, April 16, 1993, Atlanta, Georgia.This work was partially supported by a Higher Education Grant from the Dwight D. Eisenhower Mathematics and Science Education Improvement Program. 相似文献
