The inclusion of socioscientific issues (SSIs) in the science curriculum is a well-established trend internationally. Apart from claims about its innate value, one of the rationales for this approach is its potential for helping to counter declining interest and participation. SSIs involve the use of science and are of interest to society, also raising ethical and moral dilemmas. Introducing such problems presents a significant and usually cross-disciplinary challenge to curriculum developers and teachers. The aim of this paper is to examine how this challenge has been met when judged against contemporary views of the issues concerned. It first explores how SSIs have been interpreted in an important and innovative science course for students aged 14–16 in England, entitled Twenty First Century Science. This paper analyses the Twenty First Century Science textbooks, focusing in detail on two SSIs, reproductive genetic technology and climate change. For each of these issues, the key ideas present in the social science literature surrounding the problems are outlined. This review is then used as an analytical framework to examine how the issues are presented in the textbooks. It is argued in this paper that the perspectives the textbooks take on these issues largely do not include perspectives from social science disciplines. It goes on to suggest that the development of future SSI-based curricula needs to take account of these wider, often interdisciplinary, perspectives. 相似文献

Research in socioscientific issue (SSI)-based interventions is relatively new (Sadler in Journal of Research in Science Teaching 41:513–536, 2004; Zeidler et al. in Journal of Research in Science Teaching 46:74–101, 2009), and there is a need for understanding more about the effects of SSI-based learning environments (Sadler in Journal of Research in Science Teaching 41:513–536, 2004). Lee and Witz (International Journal of Science Education 31:931–960, 2009) highlighted the need for detailed case studies that would focus on how students respond to teachers’ practices of teaching SSI. This study presents case studies that investigated the development of secondary school students’ science understanding and their socioscientific reasoning within SSI-based learning environments. A multiple case study with embedded units of analysis was implemented for this research because of the contextual differences for each case. The findings of the study revealed that students’ understanding of science, including scientific method, social and cultural influences on science, and scientific bias, was strongly influenced by their experiences in SSI-based learning environments. Furthermore, multidimensional SSI-based science classes resulted in students having multiple reasoning modes, such as ethical and economic reasoning, compared to data-driven SSI-based science classes. In addition to portraying how participants presented complexity, perspectives, inquiry, and skepticism as aspects of socioscientific reasoning (Sadler et al. in Research in Science Education 37:371–391, 2007), this study proposes the inclusion of three additional aspects for the socioscientific reasoning theoretical construct: (1) identification of social domains affecting the SSI, (2) using cost and benefit analysis for evaluation of claims, and (3) understanding that SSIs and scientific studies around them are context-bound. 相似文献

The transfer of matter and energy from one organism to another and between organisms and their physical setting is a fundamental concept in life science. Not surprisingly, this concept is common to the Benchmarks for Science Literacy (American Association for the Advancement of Science, 1993 ), the National Science Education Standards (National Research Council, 1996 ), and most state frameworks and likely to appear in any middle‐school science curriculum material. Nonetheless, while topics such as photosynthesis and cellular respiration have been taught for many years, research on student learning indicates that students have difficulties learning these ideas. In this study, nine middle‐school curriculum materials—both widely used and newly developed—were examined in detail for their support of student learning ideas concerning matter and energy transformations in ecosystems specified in the national standards documents. The analysis procedure used in this study was previously developed and field tested by Project 2061 of the AAAS on a variety of curriculum materials. According to our findings, currently available curriculum materials provide little support for the attainment of the key ideas chosen for this study. In general, these materials do not take into account students' prior knowledge, lack representations to clarify abstract ideas, and are deficient in phenomena that can be explained by the key ideas and hence can make them plausible. This article concludes with a discussion of the implications of this study to curriculum development, teaching, and science education research based on shortcomings in today's curricula. © 2004 Wiley Periodicals, Inc.

Socioscientific issues encompass social dilemmas with conceptual or technological links to science. The process of resolving these issues is best characterized by informal reasoning which describes the generation and evaluation of positions in response to complex situations. This article presents a critical review of research related to informal reasoning regarding socioscientific issues. The findings reviewed address (a) socioscientific argumentation; (b) relationships between nature of science conceptualizations and socioscientific decision making; (c) the evaluation of information pertaining to socioscientific issues, including student ideas about what counts as evidence; and (d) the influence of an individual's conceptual understanding on his or her informal reasoning. This synthesis of the current state of socioscientific issue research provides a comprehensive framework from which future research can be motivated and decisions about the design and implementation of socioscientific curricula can be made. The implications for future research and classroom applications are discussed. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 513–536, 2004 相似文献

This paper draws together two important agendas in science education. The first is making science education more inclusive such that students from non-Western or indigenous cultures can benefit from culturally relevant curricula. The second is integrating technology into the curriculum under the umbrella of Science–Technology–Society (STS) education to embrace the social aspects of science, with technology serving as a bridge. The advancement of the first agenda is hindered by the pursuance by both Western and non-Western societies of narrow cultural and practical goals without considering the development of science and technology from a cross-cultural perspective. The second agenda is limited by the misconception that technology is applied science, leading to the exclusion from STS discussions of pre-science or indigenous technologies developed by non-Western cultures. Through selected case studies of the evolution of Chinese traditional technologies and their interaction with science, this paper offers a perspective from the Far East, and argues for situating culturally responsive science education in broader historical and cross-cultural contexts to acknowledge the multi-cultural contributions to science and technology. A form of cross-cultural STS education is advanced, encompassing the cultural basis of technological developments, technology diffusion, interactions of traditional technology with science, and the potential development of traditional or indigenous technologies. This approach provides a bridge between the existing universal science education paradigm promoted in the West and the different forms of multi-cultural education advocated by indigenous science educators. To translate theory into practice, a conceptual framework is proposed in which the essential transdisciplinary knowledge base, curricular goals, and pedagogical approaches are embedded. 相似文献

This is an editorial report on the outcomes of an international conference sponsored by a grant from the National Science Foundation (NSF) (REESE-1205273) to the School of Education at Boston University and the Center for Philosophy and History of Science at Boston University for a conference titled: How Can the History and Philosophy of Science Contribute to Contemporary US Science Teaching? The presentations of the conference speakers and the reports of the working groups are reviewed. Multiple themes emerged for K-16 education from the perspective of the history and philosophy of science. Key ones were that: students need to understand that central to science is argumentation, criticism, and analysis; students should be educated to appreciate science as part of our culture; students should be educated to be science literate; what is meant by the nature of science as discussed in much of the science education literature must be broadened to accommodate a science literacy that includes preparation for socioscientific issues; teaching for science literacy requires the development of new assessment tools; and, it is difficult to change what science teachers do in their classrooms. The principal conclusions drawn by the editors are that: to prepare students to be citizens in a participatory democracy, science education must be embedded in a liberal arts education; science teachers alone cannot be expected to prepare students to be scientifically literate; and, to educate students for scientific literacy will require a new curriculum that is coordinated across the humanities, history/social studies, and science classrooms. 相似文献

Functional scientific literacy demands an informed citizenry capable of negotiating controversial socioscientific issues (SSI). Perspective taking is critical to SSI implementation as it enables understanding of the diverse cognitive and emotional perspectives of others. Science teacher educators must therefore facilitate teachers’ promotion of classroom environments that value diverse perspectives. The purpose of this theoretical paper is to propose the HARTSS model through which successful practices that promote perspective taking in the humanities, arts, and social sciences are identified and translated into socioscientific contexts, thereby developing an array of promising interventions designed for science teacher educators to foster perspective taking in current and future science teachers and their students. 相似文献

The failure of much curriculum innovation has been attributed to the neglect by innovators of teachers’ perceptions. The purpose
of this study was to investigate inservice science teachers views of integrating Science, Technology and Society (STS) issues
into the science curriculum and identify the factors that influence their decisions concerning integrating STS issues (or
not). The study used mixed methods (questionnaire and interviews) with Egyptian science teachers who teach science courses
for 12- to 14-year-old students. The findings indicate that unless curriculum developers take account of teachers’ beliefs
and knowledge and the sociocultural factors that shape or influence those beliefs in designing and planning new STS curriculum
materials, these materials are unlikely to be implemented according to their intended plan. 相似文献

Science in schooling has for the first time been recently considered as a verified whole for the 10 or 12 of its compulsory
years, rather than for a limited sector of schooling or for a particular group of students. This has also been occurring as
part of a wider review and plan for the whole curriculum of schooling. A framework has been provided consisting of a matrix
of strands of intended content for learning across a number of levels approximating the years of schooling. There is a sense
and expectation of continuous progression in the learning of science. Earlier notions of progression in science curricula
are explored and compared with what has now appeared in the national curricula in England and Wales, New Zealand and Australia.
The notions of curriculum opportunity and curriculum purpose for science education are introduced as factors that would lead
to a shift in the sense of progression from a focus on Science itself to an emphasis on the learners' changing need of Science
as they progress through the years of schooling.

Abstract: Gestures may provide the long sought‐for bridge between science laboratory experiences and scientific discourse about abstract entities. In this article, we present our results of analyzing students' gestures and scientific discourse by supporting three assertions about the relationship between laboratory experiences, gestures, and scientific discourse: (1) gestures arise from the experiences in the phenomenal world, most frequently express scientific content before students master discourse, and allow students to construct complex explanations by lowering the cognitive load; (2) gestures provide a medium on which the development of scientific discourse can piggyback; and (3) gestures provide the material that “glues” layers of perceptually accessible entities and abstract concepts. Our work has important implications for laboratory experiments which students should attempt to explain while still in the lab rather than afterwards and away from the materials. © 2000 John Wiley & Sons, Inc.

Internationally there is concern that many science teachers do not address socioscientific issues (SSI) in their classrooms, particularly those that are controversial. However with increasingly complex, science-based dilemmas being presented to society, such as cloning, genetic screening, alternative fuels, reproductive technologies and vaccination, there is a growing call for students to be more scientifically literate and to be able to make informed decisions on issues related to these dilemmas. There have been shifts in science curricula internationally towards a focus on scientific literacy, but research indicates that many secondary science teachers lack the support and confidence to address SSI in their classrooms. This paper reports on a project that developed a pedagogical model that scaffolded teachers through a series of stages in exploring a controversial socioscientific issue with students and supported them in the use of pedagogical strategies and facilitated ways of ethical thinking. The study builds on existing frameworks of ethical thinking. It presents an argument that in today’s increasingly pluralistic society, these traditional frameworks need to be extended to acknowledge other worldviews and identities. Pluralism is proposed as an additional framework of ethical thinking in the pedagogical model, from which multiple identities, including cultural, ethnic, religious and gender perspectives, can be explored. 相似文献

ABSTRACTPrevious research has documented that students who engage with socioscientific issues can acquire some of the complex competences and skills typically related to scientific literacy. But an emerging field of research on science teachers’ understanding and use of socioscientific issues, has documented that a range of challenges hinders the uptake of socioscientific issues. In this study, we investigated the interpretation and implementation of socioscientific issues among Danish biology teachers. We conducted five in-depth group interviews and validated the emergent themes from the teachers’ talk-in-interaction by distributing a questionnaire. Our findings suggest that the participating teachers generally harbour a content-centred interpretation of socioscientific issues which manifests itself in at least three separate ways. First, the teachers generally use socioscientific issues as a vehicle to teach factual biological content. Second, the teachers emphasised mastery of factual content in their assessment. Third, the teachers tended to reduce socioscientific issues to specific biological contents in a way may preclude students from engaging with the real socioscientific issue. Our findings are particularly significant for science educators, policy-makers and curriculum designers, as we argue that key aspects of this content-centred interpretation may be a coping strategy used to navigate a divided curriculum. 相似文献

科学史融入科学课程对提升学生的科学素养有重要的意义。科学史的本源价值是其元认知价值——展现科学的本质和科学技术与社会的关系。辉格式科学史给学生呈现出一副歪曲的科学发展图景,不利于学生理解科学的本质以及科学技术与社会的关系。其产生的根本原因是教育者价值观的错位,即教育哲学中的知识中心主义、科学哲学中的素朴经验论和历史哲学中的移时史观;直接原因在于科学家的一些"不当行为"与科学教育工作者对科学、科学家所持的刻板印象相冲突,他们按自己的刻板印象去重塑科学史。科学课程应变辉格式科学史为真实的科学发展历程。 相似文献

Science educators are typically dismayed by the failure of students to use relevant scientific knowledge when reasoning about socioscientific issues. Except for the well-documented association between having more knowledge about a topic and a tendency to use that knowledge, the influences on students’ evaluation of information in socioscientific issues are not well understood. This study presents an initial investigation into the associations between upper elementary students’ attitudes towards science and their evaluation of information about a socioscientific issue. We surveyed the science attitudes of 49 sixth grade students and then asked them to evaluate information about a socioscientific issue (alternative energy use). Positive attitudes were associated with a more scientific approach to evaluating information in the task. When trying to make judgments, students with generally positive attitudes towards science were more likely to attend to scientific information than other sources. Scientific information, nonetheless, served a variety of socially oriented goals in students’ evaluations. These findings warrant further research on the relationship between science attitudes and reasoning about socioscientific issues and support the argument for connecting school science more clearly with everyday concerns. 相似文献

Health professionals and policymakers are asking educators to place more emphasis on food and nutrition education. Integrating these topics into science curricula using hand‐on, food‐based activities may strengthen students’ understanding of science concepts. The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. Previous studies have shown that students experiencing the FoodMASTER curriculum were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations. The purpose of this study was to: (1) assess 4th graders food‐related multidisciplinary science knowledge, and (2) compare gains in food‐related science knowledge after implementation of an integrated, food‐based curriculum. During the 2009–2010 school year, FoodMASTER researchers implemented a hands‐on, food‐based intermediate curriculum in eighteen 4th grade classrooms in Ohio (n = 9) and North Carolina (n = 9). Sixteen classrooms in Ohio (n = 8) and North Carolina (n = 8), following their standard science curricula, served as comparison classrooms. Students completed a researcher‐developed science knowledge exam, consisting of 13 multiple‐choice questions administered pre‐ and post‐test. Only subjects with pre‐ and post‐test scores were entered into the sample (Intervention n = 343; Control n = 237). No significant differences were observed between groups at pre‐test. At post‐test, the intervention group scored (9.95 ± 2.00) significantly higher (p = 0.000) than the control group (8.84 ± 2.37) on a 13‐point scale. These findings suggest the FoodMASTER intermediate curriculum is more effective than a standard science curriculum in increasing students’ multidisciplinary science knowledge related to food. 相似文献

A theoretical model of nonscience majors' motivation to learn science was tested by surveying 369 students in a large‐enrollment college science course that satisfies a core curriculum requirement. Based on a social‐cognitive framework, motivation to learn science was conceptualized as having both cognitive and affective influences that foster science achievement. Structural equation modeling was used to examine the hypothesized relationships among the variables. The students' motivation, as measured by the Science Motivation Questionnaire (SMQ), had a strong direct influence on their achievement, as measured by their science grade point average. The students' motivation was influenced by their belief in the relevance of science to their careers. This belief was slightly stronger in women than men. Essays by the students and interviews with them provided insight into their motivation. The model suggests that instructors should strategically connect science concepts to the careers of nonscience majors through such means as case studies to increase motivation and achievement. © 2006 Wiley Periodicals, Inc.

In the present STEM (Science, Technology, Engineering, and Mathematics)-driven society, socioscientific issues (SSI) have become a focus globally and SSI research has grown into an important area of study in science education. Since students attending the social and science programs have a different focus in their studies and research has shown that students attending a science program are less familiar with argumentation practice, we make a comparison of the supporting reasons social science and science majors use in arguing different SSI with the goal to provide important information for pedagogical decisions about curriculum and instruction. As an analytical framework, a model termed SEE-SEP covering three aspects (of knowledge, value, and experiences) and six subject areas (of sociology/culture, economy, environment/ecology, science, ethics/morality, and policy) was adopted to analyze students’ justifications. A total of 208 upper secondary students (105 social science majors and 103 science majors) from Sweden were invited to justify and expound their arguments on four SSI including global warming, genetically modified organisms (GMO), nuclear power, and consumer consumption. The results showed that the social science majors generated more justifications than the science majors, the aspect of value was used most in students’ argumentation regardless of students’ discipline background, and justifications from the subject area of science were most often presented in nuclear power and GMO issues. We conclude by arguing that engaging teachers from different subjects to cooperate when teaching argumentation on SSI could be of great value and provide students from both social science and science programs the best possible conditions in which to develop argumentation skills. 相似文献

The quantitative results of Sources of Self‐Efficacy in Science Courses‐Physics (SOSESC‐P) are presented as a logistic regression predicting the passing of students in introductory Physics with Calculus I, overall as well as disaggregated by gender. Self‐efficacy as a theory to explain human behavior change [Bandura [ 1977 ] Psychological Review, 84(2), 191–215] has become a focus of education researchers. Zeldin and Pajares [Zeldin & Pajares [ 2000 ] American Educational Research Journal, 37(1), 215] and Zeldin, Britner, and Pajares [ 2008 ] Journal of Research in Science Teaching, 45(9), 1036–1058] found evidence that men and women draw on different sources for evaluation of their self‐efficacy in science fields. Further, self‐efficacy is one of the primary dimensions of students' overall science identity and contributes to their persistence in physics [Hazari, Sonnert, Sadler, & Shanahan, 2010 Journal of Research in Science Teaching 47(8), 978–1003]. At Florida International University we have examined the self‐efficacy of students in the introductory physics classes from the perspective of gender theory, with the intention of understanding the subtleties in how sources of self‐efficacy provide a mechanism for understanding retention in physics. Using a sequential logistic regression analysis we uncover subtle distinctions in the predictive ability of the sources of self‐efficacy. Predicting the probability of passing for women relies primarily on the vicarious learning experiences source, with no significant contribution from the social persuasion experiences, while predicting the probability of passing for men requires only the mastery experiences source. © 2012 Wiley Periodicals, Inc.
