SCI-LINK: An innovative project linking research scientists and science teachers

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.     

The Implementation and Evaluation of Comprehensive School Guidance Programs in the United States: Progress and Prospects

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.     

What do prospective students look for in higher degrees by research? A scale development study

ABSTRACT

This empirical investigation was aimed at conceptualizing, developing and validating a scale for the measurement of the quality of higher degrees by research (HDR-QUAL). For that purpose, this study specifically measured perceptions of higher degrees by research (HDR) students about the constituents of HDR quality in Pakistani tertiary education institutions. Following the 7-step process of scale development, three studies were conducted in order to develop an initial pool of scale items, establishing proposed scale validity and reliability, and assessing nomological behavior of the proposed scale. The principal component analysis with Varimax rotation method resulted in a 3-factor solution, subsequently proposing a 15-item scale. The model fit indices of measurement and the higher-order model indicated a satisfactory fit to data. Finally, the resultant three factors, i.e. financial assistance, supervisory expertise, and infrastructural support, converged into a unidimensional HDR-QUAL scale that was found positively associated with student satisfaction, thus, confirming nomological validity as well. Important policy measures and directions for future research are proposed at the end.     

Improving science teachers' conceptions of nature of science: a critical review of the literature

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.
