Summary The major purpose of the SCI-LINK Projects was to explore ways of linking research scientists and school science teachers. Not only did the project provide these teachers with a better understanding of scientific environmental research and recent findings, but it allowed them to develop activities and other instructional materials they could use in their classrooms. Leadership skills also were developed as evidenced by the Master Teachers that evolved and the many professional activities in which they have been engaged since the first institutes. Many things were done during the course of the project in order to make the process more efficient. These include assistance to scientists in making their presentations and field trips more effective and helping teachers with their writing and library skills. Also explored were the nature and format for the activities the teachers developed and how they can best be evaluated and disseminated. Positive feedback from teachers and the continued interest of research scientists to participate has led to another project patterned after the model used in the SCI-LINK Project. This second generation project, GLOBE-NET, also supported by the National Science Foundation, involves scientists and teachers in the development of instructional materials on global change. At least some of the efforts to improve science education should include scientists and teachers as partners. The model used in the SCI-LINK Project provides one way of doing so.  相似文献

The evolution of guidance in the schools of the United States from a position to a service to a program is described. Then the prevailing structure for guidance, the comprehensive guidance program is presented. This section of the article provides a brief overview of the basic elements of the program. Finally, the article closes with discussion of guidance program evaluation as well as presents the results of several studies that offer evidence of the impact of guidance programs. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

To address a key gap in theorizing and research, we consider relational uncertainty as an explanation for why individuals experiencing depressive symptoms may be reluctant to talk about sensitive issues. We report closed-ended online survey data from 126 romantic couples in which one or both partners had been professionally diagnosed with depression. Results indicated that relational uncertainty mediated the positive association between depressive symptoms and topic avoidance. Partner effects from men to women also emerged. These findings are valuable for identifying relational uncertainty as a mechanism that may explain people's unwillingness to discuss challenging topics when they are experiencing depressive symptoms.  相似文献

This paper aimed to review, and assess the 'effectiveness' of the attempts undertaken to improve prospective and practising science teachers' conceptions of nature of science (NOS). The reviewed attempts could be categorized into two general approches: implicit and explicit. Implicit attempts utilized science process-skills instruction or engagement in science-based inquiry activities to improve science teachers' conceptions of NOS. To achieve the same goal, explicit attempts used instruction geared towards various aspects of NOS and/or instruction that utilized elements from history and philosophy of science. To the extent that teachers' NOS conceptions were faithfully assessed by the instruments used in the reviewed studies, the explicit approach was relatively more effective in enhancing teachers' views. The relative ineffectiveness of the implicit approach could be attributed to two inherent assumptions. The first is that developing an understanding of NOS is an 'affective', as compared to a 'cognitive', learning outcome. The second ensuing assumption is that learners would necessarily develop understandings of NOS as a by-product of engaging in science-realated activities. However, despite the relative 'effectiveness' of the explicit approach, much is still required in terms of fostering among science teachers 'desired' understandings of NOS. The paper emphasizes that explicitness and reflectivness should be given prominence in any future attempts aimed at improving teachers' concepts of NOS.  相似文献
