This article reports on the study of the components of scientific imagination and describes the scales used to measure scientific imagination in Korean elementary and secondary students. In this study, we developed an inventory, which we call the Scientific Imagination Inventory (SII), in order to examine aspects of scientific imagination. We identified three conceptual components of scientific imagination, which were composed of (1) scientific sensitivity, (2) scientific creativity, and (3) scientific productivity. We administered SII to 662 students (4th–8th grades) and confirmed validity and reliability using exploratory factor analysis and Cronbach α coefficient. The characteristics of Korean elementary and secondary students' overall scientific imagination and difference across gender and grade level are discussed in the results section. 相似文献

Abstract The article discusses the use of various institutions of scientific imperialism, including the institution of publishing academic articles in English, the institution of standardizing how research should be reported, and the institution of indexing of articles in two global databases. We show that the establishment of institutions of scientific imperialism entails a number of negative trends: slowing down the publication of articles, the loss of a national research culture, and formulating and presenting research results to fit the requirements of indexing databases. We identify possible approaches to mitigate the negative effects associated with the expansion of the institutions of scientific imperialism. 相似文献

This paper presents and comments on Mario Bunge??s scientific realism. After a brief introduction in Sects. 1 and 2 outlines Bunge??s conception of realism. Focusing on the case of quantum mechanics, Sect. 3 explores how his approach plays out for problematic theories. Section?4 comments on Bunge??s project against the background of the current debate on realism in contemporary analytic philosophy. 相似文献

Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines. 相似文献

The purpose of this study was to understand the impact of an apprenticeship program on high school students’ understanding
of the nature of scientific inquiry. Data related to seventeen students’ understanding of science and scientific inquiry were
collected through open-ended questionnaires. Findings suggest that although engagement in authentic scientific research helped
the participants to develop competency in experimentation methods it had limited impact on participants’ learning of the implicit
aspects of scientific inquiry and NOS. Discussion focuses on the importance of making the implicit assumptions of science
explicit to the students in such authentic scientific inquiry settings through structured curriculum. 相似文献

With the goal of producing scientifically literate citizens who are able to make informed decisions and reason critically when science intersects with their everyday lives, the National Research Council (NRC) has produced two recent documents that call for a new approach to K-12 science education that is based on scientific practices, crosscutting concepts, and disciplinary core ideas. These documents will potentially influence future state standards and K-12 curricula. Teachers will need support in order to teach science using a practices based approach, particularly if they do not have strong science backgrounds, which is often the case with elementary teachers. This study investigates one cohort (n = 19) of preservice elementary teachers’ ideas about scientific practices, as developed in a one-semester elementary science teaching methods course. The course focused on eight particular scientific practices, as defined by the National Research Council’s A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas (2012). Participants’ written reflections, lesson plans and annotated teaching videos were analyzed in fine detail to better understand their ideas about what it means to engage in each of the practices. The findings suggest that preservice elementary teachers hold promising ideas about scientific practices (such as an emphasis on argumentation and communication between scientists, critical thinking, and answering and asking questions as the goal of science) as well as problematic ideas (including confusion over the purpose of modeling and the process of analysis, and conflating argumentation and explanation building). These results highlight the strengths and limitations of using the Framework (NRC 2012) as an instructional text and the difficulties of differentiating between preservice teachers’ content knowledge about doing the practices and their pedagogical knowledge about teaching the practices. 相似文献

Life sciences faculty agree that developing scientific literacy is an integral part of undergraduate education and report that they teach these skills. However, few measures of scientific literacy are available to assess students’ proficiency in using scientific literacy skills to solve scenarios in and beyond the undergraduate biology classroom. In this paper, we describe the development, validation, and testing of the Test of Scientific Literacy Skills (TOSLS) in five general education biology classes at three undergraduate institutions. The test measures skills related to major aspects of scientific literacy: recognizing and analyzing the use of methods of inquiry that lead to scientific knowledge and the ability to organize, analyze, and interpret quantitative data and scientific information. Measures of validity included correspondence between items and scientific literacy goals of the National Research Council and Project 2061, findings from a survey of biology faculty, expert biology educator reviews, student interviews, and statistical analyses. Classroom testing contexts varied both in terms of student demographics and pedagogical approaches. We propose that biology instructors can use the TOSLS to evaluate their students’ proficiencies in using scientific literacy skills and to document the impacts of curricular reform on students’ scientific literacy. 相似文献

“The Scientific Method” as it has been portrayed in popular and introductory contexts has been declared a myth. The variation that one finds in introductory presentations of “The Scientific Method” is explained by the fact that there is no canonical account among historians and philosophers of science. What, in particular, is wrong with “The Scientific Method”? This essay provides a fairly comprehensive survey of shortcomings of “The Scientific Method”. Included are corrections to several misconceptions that often accompany such presentations. Rather than treating “The Scientific Method” as a useful approximation or an ideal, the myth should be discarded. Lessons can be learned for introductory pedagogical contexts from considering the shortcomings of the myth. 相似文献
