Developing scientifically literate students who understand the socially contextualized nature of science and technology is
a national focus of science education reform. Science educators’ perceptions of risks and benefits of new technologies (such
as biotechnology) may shape their instructional approaches. This study examined the perceived risk of biotechnology of four
groups of science educators: pre-service science teachers, in-service science teachers, biology graduate teaching assistants,
and biology professors (n = 91). Data sources included a survey instrument and card sort task designed to determine the respondents’ structure of risk
perception and factors contributing to this structure. The perceptions of the four educator groups were compared and contrasted
along these dimensions. Results showed that the teacher groups were similar along many aspects of risk perception, but university
professors were more likely to view the more subtle “gray areas” between biotechnology risks. The results are discussed in
the context of understanding teacher risk perception on science pedagogical practice as well as the role of content knowledge
and teaching experience on risk perception formation. 相似文献

Reflection on several decades of science teaching at the secondary-school level leads to the strong suggestion that a theory
of science education should be based on arguments emanating from insights into the process of meaningful communication in
the light of modern epistemology. These arguments show that the teacher’s personality and engagement with the subject is a
major source of interest and devotion of students who try to understand the presented ideas. An analysis of the conditions
of this engagement leads to a vision for a future understanding of the teaching process, especially in science teaching. 相似文献

Science education and Christian education are not compatible if byChristian education one means teaching someone to be a Christian. Onegoal of science education is to give students factual knowledge. Even whenthere is no actual conflict of this knowledge with the dogmas ofChristianity, there exists the potential for conflict. Another goal ofscience education is to teach students to have the propensity to be sensitiveto evidence: to hold beliefs tentatively in light of evidence and to rejectthese beliefs in the light of new evidence if rejection is warranted by thisevidence. This propensity conflicts with one way in which beliefs are oftentaught in Christian education: namely as fundamental dogmas, rather than assubject to revision in the light of the evidence. 相似文献

Evaluating Instrument Quality in Science Education: Rasch‐based analyses of a Nature of Science test
Irene Neumann Knut Neumann Ross Nehm 《International Journal of Science Education》2013,35(10):1373-1405
Given the central importance of the Nature of Science (NOS) and Scientific Inquiry (SI) in national and international science standards and science learning, empirical support for the theoretical delineation of these constructs is of considerable significance. Furthermore, tests of the effects of varying magnitudes of NOS knowledge on domain‐specific science understanding and belief require the application of instruments validated in accordance with AERA, APA, and NCME assessment standards. Our study explores three interrelated aspects of a recently developed NOS instrument: (1) validity and reliability; (2) instrument dimensionality; and (3) item scales, properties, and qualities within the context of Classical Test Theory and Item Response Theory (Rasch modeling). A construct analysis revealed that the instrument did not match published operationalizations of NOS concepts. Rasch analysis of the original instrument—as well as a reduced item set—indicated that a two‐dimensional Rasch model fit significantly better than a one‐dimensional model in both cases. Thus, our study revealed that NOS and SI are supported as two separate dimensions, corroborating theoretical distinctions in the literature. To identify items with unacceptable fit values, item quality analyses were used. A Wright Map revealed that few items sufficiently distinguished high performers in the sample and excessive numbers of items were present at the low end of the performance scale. Overall, our study outlines an approach for how Rasch modeling may be used to evaluate and improve Likert‐type instruments in science education. 相似文献

In this paper I inspect a ‘semantic’ view of scientific models taken from contemporary philosophy of science—I draw upon the so-called ‘semanticist family’, which frontally challenges the received, syntactic conception of scientific theories. I argue that a semantic view may be of use both for science education in the classrooms of all educational levels, and for research and innovation within the discipline of didactics of science. I explore and characterise a model-based account of the nature of science, and derive some implications that may be of interest for our community. 相似文献

This paper discusses R.S. Peters’ concept of education, particularly his notion of cognitive perspective and its relevance to school science education. In light of the problems inherent in any attempt to define the notion of scientific literacy, it is argued that the development of cognitive perspective can be considered an important, if not the ultimate, goal of school science education. Such a goal not only provides an alternative way to view the development of scientific literacy, but it also points to a conception of scientific literacy that is neither too narrow nor too broad. In view of recent reform efforts that promote a utilitarian and instrumentalist conception of school science education, Peters’ notion of cognitive perspective can provide food for thought for all those interested in a science education that educates students in science by helping them understand the personal and the wider significance of scientific knowledge. Such a conception of school science education is in line with the view that education and learning should make students change their outlook on the world. In addition, such a conception can enrich the ongoing dialogue on scientific literacy as the primary goal of school science education. 相似文献

In the early 1930s, the young Antoni Quintana-Marí undertook some research on Antoni de Martí i Franquès, one of the most
prominent Catalan scientists of the Enlightenment. This scientist worked in Tarragona, where Quintana-Marí lived. Quintana-Marí
learnt about Martí i Franquès from Josep Estalella, his teacher of physics and chemistry at the secondary school. It was while
researching on Martí i Franquès that Quintana-Marí became a true historian of science. He subsequently collaborated with other
Spanish and foreign historians of science in the early years of this discipline. Quintana-Marí never forgot that his passion
for history of science had been aroused by his school teacher. 相似文献

In case studies of two first-year elementary classroom teachers, we explored the influence of informal science education (ISE) they experienced in their teacher education program. Our theoretical lens was identity development, delimited to classroom science teaching. We used complementary data collection methods and analysis, including interviews, electronic communications, and drawing prompts. We found that our two participants referenced as important the ISE experiences in their development of classroom science identities that included resilience, excitement and engagement in science teaching and learning–qualities that are emphasized in ISE contexts. The data support our conclusion that the ISE experiences proved especially memorable to teacher education interns during the implementation of the No Child Left Behind policy which concentrated on school-tested subjects other than science. 相似文献

This paper discusses the findings of an evaluative and interpretive study into the potential of in‐service education to improve science education in Swaziland. Short‐term and long‐term effects of an in‐service intervention are evaluated in terms of changes in classroom processes. The teaching approach of participating teachers has been monitored and analysed before, during and 1 year after the in‐service intervention, to assess whether changes occurred. The study revealed the subjective interpretations of teachers about those changes, also in relation to contextual factors. Recommendations are put forward to enhance the potential of in‐service education in comparable contexts. 相似文献

A growing body of research argues that teachers’ beliefs and practices should be studied within the sociocultural contexts of their work because the relationship between their beliefs and practices is both complex and context-dependent. There is a need for further research in this area in understudied contexts such as developing countries, in order to promote effective education in schools and the professional development of teachers. This paper argues that if this ‘black box’ of sociocultural contexts in which science teachers are embedded is better understood, it may be possible to identify specific aspects of these contexts related to educational organizations that act as either supports or barriers to pedagogical reform or to implementing innovations in science education. Consequently, the main purpose of this study is to explore the sociocultural contexts of ten Egyptian science teachers and to what extent these sociocultural contexts help in understanding teachers’ pedagogical beliefs and practices. This paper, by utilizing a multi-grounded theory approach and qualitative methods, reveals a variety of sociocultural contexts that are related to teachers’ pedagogical beliefs and practices. 相似文献

This study of classroom discourse and other data from a physical science course for in-service teachers show the areas of
success and challenge of the participants in making claims supported by justifications. It also shows that the teachers learned
to make scientific claims and were able to make some justifications. Nevertheless, many found the process difficult. Some
of those who performed well in the course did not consider the pedagogy suitable for their own students. The implications
of the findings for elementary teacher education are discussed. 相似文献

Summaries English Before constructing a new curriculum for any level in integrated‐science education, it is very important to establish a basic philosophy of science teaching which reflects a symbiotic relationship between education and the socio‐economic development in a particular country of the world. The curriculum structure of integrated‐science education should broaden the basis of curricular decision and should be designated to follow the expectations of the society in providing professional intellectual training so that education can make a significant contribution to the socio‐economic growth of the country. This basic assumption which established a link between cultural and socio‐economic growth, involves a diversification of the cultural trends of science education which must become appropriate to the economic and historical context of each country in a fast changing world of work. Therefore, by critically removing outside influences in the transmission of scientific knowledge, there should be less uniformity in the context and methods of teaching, and considerable restructuring of education for each country should occur. Thus, considering the historical and geographical differences, a new order in international division of labour would come into being. In such a hypothesis, a research‐oriented integrated curriculum in science education can play a central role (certainly a better one than in the traditional, discipline‐oriented scheme of science teaching) in obtaining an adequate interaction between scientific education and social problems; this is required for modern cultural and economic development of the world. 相似文献
