This article presents a case study of 10 high-profile Australian research scientists. These scientists are highly committed to engaging with the public. They interact with a wide range of groups in the community, including the traditional media. They are aware that they are seen as representatives of science at a time when the authority of science and scientists is threatened in Australia by controversy around issues such as climate change and vaccination. Through their experiences of interacting with non-scientists, they have developed views about qualities, characteristics and knowledge that contribute to, or inhibit, positive interactions between scientists and non-scientists. Their experiences and insights highlight aspects of contemporary science that are not generally acknowledged in science curricula.  相似文献

In this study American preservice science TEACHERS' responses on Kimball's Nature of Science Survey (NOSS) were used as a basis for analyzing the sense of the nature of science held by a group of Nigerian preservice science teachers. From an item-by-item comparison two salient differences were noted. These differences are quite interesting and important, and one would expect to see replication attempts in the near future. The primary difference was that the Nigerian students were much more inclined to see science as a way of producing useful technology. Given the national interests of a developing nation this is an understandable perception and one common among government policy makers. Nevertheless, it is a view with potential long-range dangers if this view of science is effectively transferred from teacher to student. For example, such a view is likely to raise false expectations in the general population, which when not achieved could result in widespread rejection of science. The second distinctive of the Nigerian students' sense of the nature of science had to do with the openness of science. These students perceived scientists as nationalistic and secretive about their work. This finding is troubling and indicates an important line of investigation: What image of science, especially Western science, is carried in the international media? How is that image understood in non-Western nations? What are the implications for international scientific cooperation?  相似文献

This article describes views about the nature of science held by a small sample of science students in their final year at the university. In a longitudinal interview study, 11 students were asked questions about the nature of science during the time they were involved in project work. Statements about the nature of science were characterized and coded using a framework drawing on aspects of the epistemology and sociology of science. The framework in this study has three distinct areas: the relationship between data and knowledge claims, the nature of lines of scientific enquiry, and science as a social activity. The students in our sample tended to see knowledge claims as resting solely on empirical grounds, although some students mentioned social factors as also being important. Many of the students showed significant development in their understanding of how lines of scientific enquiry are influenced by theoretical developments within a discipline, over the 5–8 month period of their project work. Issues relating to scientists working as a community were underrepresented in the students' discussions about science. Individual students drew upon a range of views about the nature of science, depending on the scientific context being discussed. © 1999 John Wiley & Sons, Inc.

Recent efforts in the science education community have highlighted the need to integrate research and theory from science communication research into more general science education scholarship. These synthesized research perspectives are relatively novel but serve an important need to better understand the impacts that the advent of rapidly emerging technologies will have on a new generation of scientists and engineers including their formal communication with engaged citizenry. This cross-national study examined postsecondary science and engineering students’ (n?=?254 from five countries: Austria, Finland, France, Israel, and USA) perspectives on the role of science communication in their own formal science and engineering education. More broadly, we examined participants’ understanding of their perceived responsibilities of communicating science and engineering to the general public when an issue contains complex social and ethical implications (SEI). The study is contextualized in the emergent technology of nanotechnology for which SEI are of particular concern and for which the general public often perceives conflicting risks and benefits. Findings indicate that student participants’ hold similar views on the need for their own training in communication as future scientists and engineers. When asked about the role that ethics and risk perception plays in research, development, and public communication of nanotechnology, participants demonstrate similar trajectories of perspectives that are, however, often anchored in very different levels of beginning concern. Results are discussed in the context of considerations for science communication training within formal science education curricula globally.  相似文献

What would it take for youth to come to see science as a source of inspiration, as something intriguing and valuable, and as a world including them as active agents and legitimate members irrespective of who they are or who they want to become? I attempt to find some answers to this question by listening in on what youth have to say about science and scientists, talk occasioned through the conduct of oral histories of scientists and reflective work about visits to their work places, conducted by a small group of youth participating in an inner-city summer gardening program. I examine how youth and scientists position each other through talk and action and how they co-construct and deconstruct science and scientists’ work. I show how creating spaces within which youths’ images are validated and taken as resources for further co-construction and deconstruction of the world of science can lead to the development of broad notions of science that make insider status a possibility for them, whether as informed citizens or scientists.  相似文献

We explored 30 Black Kindergarten‐2nd grade students' spoken narratives around pages of their science journals that the children selected as best for showing them as scientists. Because in all narratives, space–time relationships play an important role not only in situating but also in constituting them, we focused on such relationships using Bakhtin's (1981) construct of chronotopes. Our chronotopical analysis aimed at fleshing out the temporal and spatial features that were present in the children's journal pages, and in the children's ways of talking both about these features and about being scientists. Our goal was to better understand ways in which African‐American children identify with science and scientists in particular contexts: an interview with an adult who had visited their class throughout that year and a class where they were offered various opportunities to engage with science. Using six cases that maximized the variety of understandings we could develop vis‐à‐vis our research question, we show how the children's narratives were filled with differing space–time relationships in which the children found ways to showcase their agency. Thus, we provide insights into how the children authored relationships with science and scientists, negotiated the past with the present and possible future, and contextualized their narratives within various time‐spaces that had meaning for them. Moreover, multiple people populated the children's chronotopes and became intertwined with the space–time relationships that underlined their conceptions of themselves vis‐à‐vis science and scientists. Despite the varied conceptions of science and scientists that the children portrayed, their narratives communicated a high level of confidence in being able to do science and be scientists, and initiative in learning. The children's narratives were filled with hope, “able‐ness,” knowledge, affect, and possibility. These findings point to several considerations for practice. © 2012 Wiley Periodicals, Inc.

This study examined the nature of science (NOS) views of lower elementary grade level students, including their views of scientists. Participants were 23 third‐grade African American students from two Midwest urban settings. A multiple instrument approach using an open‐ended questionnaire, semi‐structured interviews, a modified version of the traditional Draw‐A‐Scientist Test (DAST), and a simple photo eliciting activity, was employed. The study sought to capture not only the students' views of science and scientists, but also their views of themselves as users and producers of science. The findings suggest that the young African American children in this study hold very distinct and often unique views of what science is and how it operates. Included are traditional stereotypical views of scientists consistent with previous research. Additionally, participants expressed excitement and self‐efficacy in describing their own relationship with science, in and outside of their formal classrooms. Implications for teaching and learning NOS as it relates to young children and children of color are discussed. © 2011 Wiley Periodicals, Inc. J Res Sci Teach 49: 1–37, 2012  相似文献

Reform recommendations around the world call for an understanding about the nature of science and the work of scientists. However, related research findings provide evidence that students hold stereotypical views of scientists and the nature of their work.

Purpose

The aim of this case study was to examine the impact of an intervention on 15 elementary school students’ views of scientists.

Sample

An urban, fifth-grade, European elementary school classroom defined the context of this study.

Design and method

The intervention was an 11-week-long investigation of a local problem concerning water quality. In carrying out this investigation the students collaborated with a young metrology scientist to collect and analyse authentic data that would help them to construct a claim about the quality of the water. The students’ initial views of scientists were investigated through a drawing activity, classroom discussions and interviews.

Results

Analysis of these data indicated that all students but one girl held very stereotypical views on scientists and the nature of their work. Analysis of interviews with each student and classroom discussions after the intervention illustrated that they reconstructed their stereotypical views of scientists and the nature of their work owing to their personal engagement in the investigation and their collaboration with the scientist.

Conclusions

The findings of this study suggest that more in-depth study into project-based approaches, out-of-school learning and school–scientist partnerships is warranted, for the purpose of determining appropriate pedagogies that support students in developing up-to-date understanding about scientists and the nature of their work.  相似文献

This study explored preservice teachers’ views of their own cultural values, the cultural values they believed scientists hold, and the relationships of these views to their conceptions of nature of science (NOS). Parallel assignments in a foundations of early childhood education and a science methods course required preservice teachers to explore their own cultural backgrounds and their perceptions of the cultural backgrounds of scientists. The Schwartz Values Inventory was used to measure preservice teachers’ personal cultural values and those they perceived of scientists. The Views of Nature of Science version B questionnaire and interviews assessed teachers’ conceptions of NOS. Copies of student work were collected and sought for themes indicating how preservice teachers perceived scientists’ cultural values and how those perceptions changed over time. We found that from the beginning to the end of the semester, preservice teachers perceived fewer differences between their own cultural values and those they perceived scientists held, though they did not change their own cultural values. We found that preservice teachers’ NOS conceptions improved, and that they were related to both their cultural values and those they perceived scientists held. Preservice teachers who indicated the fewest differences between their own cultural values and those they perceived scientists held the most informed conceptions of NOS.  相似文献

In this study, undertaken in an attempt to expand our understanding of science learning by deaf students, five teachers are interviewed about their views, based on their own experiences as Deaf students. They are all my former students and were among the first to successfully complete the upper secondary school with a university entrance certificate from a Norwegian school for deaf students. Physics was their major subject. These teachers see the systematic work in class discussions, especially on the concepts of physics, as a major contributor to their success, and they try to use similar methods in their own teaching. They believe that a thorough discussion of a topic using sign language prior to the reading of the textbook is crucial.  相似文献

This article presents the results of an exploratory study of students’ knowledge about scientists and countries’ contributions to science, aiming at answering two research questions: “In which ways are students aware of the history of scientific development carried out by different people in different places of the world? What can be influencing and shaping their awareness?” Thus, this study aimed at depicting students’ knowledge about History of Science (HOS), focusing on what they know about science being done by people and communities from different parts of the world and on how this knowledge is constructed through their engagement with school science. An exploratory research was carried out at two multicultural state secondary schools in London, UK, involving 200 students aged 12–15 (58.5% girls, 41.5% boys) and five science teachers. The method involved an initial exploration of students’ knowledge about HOS through an open-ended survey, followed by classroom-based observations and semi-structured interviews with the participants. Results showed a disconnection between remembering scientists and knowing about their work and background, hinting at an emphasis on illustrative and decontextualised approaches towards HOS. Additionally, there was a lack of diversity in these students’ answers in terms of gender and ethnicity when talking about scientists and countries in science. These findings were further analysed in relation to their implications for school science and for the fields of HOS, science education and public perception of science.  相似文献

Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students’ learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students’ inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists’ practices is very much needed. Within this context there is a need to re-examine the science teachers’ views of scientists and the cultural factors that might have an impact on teachers’ views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative–qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers’ cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists.  相似文献

In this study, we produced a documentary which portrays scientists at work and critically evaluated the use of this film as a teaching tool to help students develop an understanding of the nature of science. The documentary, “Life as a Scientist: People in Love with Caenorhabditis elegans, a Soil Nematode” encompasses the entire process of a scientific investigation by exploring the everyday life of a particular group of scientists. We explored the effectiveness of this documentary in teaching the nature of science by examining the epistemological views of college students toward science before and after viewing. In addition, we collected written responses from the students where they described which aspect of the nature of science they learned from the documentary. The scores of epistemological views toward science increased between the pretest and the posttest (p < 0.01) with the most significant increase being in their views of the role of social negotiation. In the written responses, approximately half of the students suggested that they had learned more about the role which cooperation and collaboration play in the development of scientific knowledge by watching the documentary. The documentary overall provides a valuable instructional context so that students are able to discuss and reflect on various aspects of nature of science within authentic scientific research.  相似文献

Students' images of science and scientists are generally assumed to influence their related subject choices and aspirations for tertiary education within science and technology. Several research studies have shown that many young people hold rather stereotypical images of scientists, making it hard for them to see themselves as future scientists. Adolescents' educational choices are important aspects of their identity work, and recent theories link individual choice to the perceived match between self and prototypical persons associated with that choice. In the present study, we have investigated images of scientists among the segment of the upper secondary school students (20 % of the cohort) from which future Danish scientists are recruited. Their images were rather realistic, only including vague and predominantly positive stereotypical ideas. With a particular Science-and-Me (SAM) interview methodology, we inquired into the match between self- and prototypical-scientists (N?=?30). We found high perceived similarity within a core of epistemological characteristics, while dissimilarities typically related to a social domain. However, combining interview data with survey data, we found no significant statistical relation between prototype match and aspirations for tertiary education within science and technology. Importantly, the SAM dialogue revealed how students negotiate perceived differences, and we identified four negotiation patterns that all tend to reduce the impact of mismatches on educational aspirations. Our study raises questions about methodological issues concerning the traditional use of self-to-prototype matching as an explanatory model of educational choice.  相似文献

The programme Ciencia Viva of the Portuguese Ministry of Science and Technology aims to create a greater understanding of science and science education amongst scientists, teachers, school children and the general public, each of whom is encouraged to cooperate and interact through regular contacts. The purpose is to improve practical, experimental and other forms of investigative work. To accomplish such work in schools, an overview of the state of science education worldwide is presented in terms of old and new traditions of the teaching of the physical and historical sciences the latter including the teaching of fieldwork. Traditional practices are compared with those established recently in various parts of the world in which more carefully considered understanding of the nature of science and science education has been established. In illustration of good practice, an outline is offered of the nature and rationale of two sets of curricular materials. These were designed by a team comprising staff members of the University of Aveiro and secondary school teachers and were trialled in schools. These activities are concerned with the internal rock cycle and the internal energy of the Earth in relation to plate tectonic theory. They are also related to the processes of weathering, erosion, transportation and deposition of sedimentary rocks and structures (like wave and current ripple marks) which were formed as part of the external rock cycle driven by the Sun's energy. The account concludes with an outline of the sub programme 'Geology in Summer', a fieldwork programme which introduces a holistic understanding of the workings of the outer part of the Earth to the general public. Students' perspectives and teachers' views about these experiences are generally very positive and are presented at the end. The whole programme was evaluated by an international team of scientists and science educators.  相似文献

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists’ public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi‐structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non‐scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.  相似文献

Most institutional studies of science have focused on the functioning of its reward system. Less is known about perspectives scientists develop on their variously rewarded and recognized careers. This study examines peoples subjective appraisals of attainment in academic science based on a sample of interviews with physicists who discussed their perspectives on success, including the most salient self-doubts they experience in their roles. The sample is divided into achievement echelons to see how self-doubts vary among those throughout the strata of science. Self-doubts about work accomplishment grip scientists across productivity strata, but these self-doubts grow more uniform as productivity increases. The most diverse sources of self-doubt are found among the least productive scientists in advanced professional ranks. This research was made possible by the National Science Foundation (grant number: SBR-95-01420), whose support is gratefully acknowledged.  相似文献

This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science‐related experiences in free‐choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and its communication by scientists. The three studies involved samples of visitors to an interactive science centre, visitors to a traditional natural history museum, and attendees at a series of public lectures, each given by an expert scientist in human genetics. Pretest and post‐test data collected by parallel questionnaires indicated that, despite the different nature of their experience in the three different settings, participants became more positive about the value of science and the work done by scientists and their ability to communicate with the public. At all venues, however, participants became less scientific in their thinking about the nature of scientific knowledge, becoming more likely to believe it to be infallible. The consistency of these findings was surprising, and participants’ changed views about the nature of scientific knowledge were unexpected. Possible explanations for theses outcomes were suggested in terms of participants’ reasons for attending the venue, the nature of their engagement, and the non‐controversial ways in which the exhibitions and lectures were structured. The findings suggest that the educational role of free‐choice settings should be considered carefully, particularly with regard to the representation of science.  相似文献

This article presents an analysis of how scientists are portrayed in the Lebanese national science textbooks. The purpose of this study was twofold. First, to develop a comprehensive analytical framework that can serve as a tool to analyze the image of scientists portrayed in educational resources. Second, to analyze the image of scientists portrayed in the Lebanese national science textbooks that are used in Basic Education. An analytical framework, based on an extensive review of the relevant literature, was constructed that served as a tool for analyzing the textbooks. Based on evidence-based stereotypes, the framework focused on the individual and work-related characteristics of scientists. Fifteen science textbooks were analyzed using both quantitative and qualitative measures. Our analysis of the textbooks showed the presence of a number of stereotypical images. The scientists are predominantly white males of European descent. Non-Western scientists, including Lebanese and/or Arab scientists are mostly absent in the textbooks. In addition, the scientists are portrayed as rational individuals who work alone, who conduct experiments in their labs by following the scientific method, and by operating within Eurocentric paradigms. External factors do not influence their work. They are engaged in an enterprise which is objective, which aims for discovering the truth out there, and which involves dealing with direct evidence. Implications for science education are discussed.  相似文献

Every aspect of teaching, including the instructional method, the course content, and the types of assessments, is influenced by teachers’ attitudes and beliefs. Teacher education programs play an important role in the development of beliefs regarding teaching and learning. The purpose of the study was to document pre-service teachers’ views on science, scientists, and science teaching as well as the relations between these views and the offered courses over several years spent in an elementary science teacher training program. The sample consisted of 145 pre-service elementary science teachers who were being trained to teach general science to students in the 6th through 8th grades. The research design was a cross-sectional study. Three different instruments were used to collect the data, namely, the “Draw a Scientist Test”, “Draw a Science Teacher Test”, and “Students’ Views about Science” tests. The elementary science teacher training program influenced pre-service science teachers’ views about science, scientists and science teaching to different degrees. The most pronounced impact of the program was on views about science teaching. Participants’ impressions of science teaching changed from teacher-centered views to student-centered ones. In contrast, participants’ views about scientists and science did not change much. This result could be interpreted as indicating that science teacher training programs do not change views about science and scientists but do change beliefs regarding teaching science.  相似文献
