From activity to gestures and scientific language     

Wolff‐Michael Roth  Manuela Welzel 《科学教学研究杂志》2001,38(1):103-136

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.

Moral luck and computer ethics: Gauguin in cyberspace     

David Sanford Horner 《Ethics and Information Technology》2010,12(4):299-312

I argue that the problem of ‘moral luck’ is an unjustly neglected topic within Computer Ethics. This is unfortunate given that the very nature of computer technology, its ‘logical malleability’, leads to ever greater levels of complexity, unreliability and uncertainty. The ever widening contexts of application in turn lead to greater scope for the operation of chance and the phenomenon of moral luck. Moral luck bears down most heavily on notions of professional responsibility, the identification and attribution of responsibility. It is immunity from luck that conventionally marks out moral value from other kinds of values such as instrumental, technical, and use value. The paper describes the nature of moral luck and its erosion of the scope of responsibility and agency. Moral luck poses a challenge to the kinds of theoretical approaches often deployed in Computer Ethics when analyzing moral questions arising from the design and implementation of information and communication technologies. The paper considers the impact on consequentialism; virtue ethics; and duty ethics. In addressing cases of moral luck within Computer Ethics, I argue that it is important to recognise the ways in which different types of moral systems are vulnerable, or resistant, to moral luck. Different resolutions are possible depending on the moral framework adopted. Equally, resolution of cases will depend on fundamental moral assumptions. The problem of moral luck in Computer Ethics should prompt us to new ways of looking at risk, accountability and responsibility.  相似文献   

Knowing,researching, and reporting science education: Lessons from science and technology studies     

Wolff-Michael Roth  Michelle K. McGinn 《科学教学研究杂志》1998,35(2):213-235

Recent research in science and technology studies changed the way we understand science as it is practiced—that is, how scientific knowledge emerges from social, natural, social, political, cultural, historical, and economic contingencies of scientific work. Many science educators agree that students should learn not only science but also about science. In this article, we (a) outline important findings, research methods, and ways of reporting research that emerged from science and technology studies; and (b) show how familiarity with science and technology studies research can provide science educators with valuable insights about curriculum design and research on learning. We conclude that science and technology studies can serve as a resource to science education and that there is a potential for conducting collaborative work between science education and science and technology studies. Such collaborations have the potential to yield better theories about how people become competent in science from childhood to adulthood. © 1998 John Wiley & Sons, Inc.

Authentic science experiences as a vehicle to change students’ orientations toward science and scientific career choices: Learning from the path followed by Brad     

Michiel van Eijck  Wolff-Michael Roth 《Cultural Studies of Science Education》2009,4(3):611-638

Bringing a greater number of students into science is one of, if not the most fundamental goals of science education for all, especially for heretofore-neglected groups of society such as women and Aboriginal students. Providing students with opportunities to experience how science really is enacted—i.e., authentic science—has been advocated as an important means to allow students to know and learn about science. The purpose of this paper is to problematize how “authentic” science experiences may mediate students’ orientations towards science and scientific career choices. Based on a larger ethnographic study, we present the case of an Aboriginal student who engaged in a scientific internship program. We draw on cultural–historical activity theory to understand the intersection between science as practice and the mundane practices in which students participate as part of their daily lives. Following Brad, we articulate our understanding of the ways in which he hybridized the various mundane and scientific practices that intersected in and through his participation and by which he realized his cultural identity as an Aboriginal. Mediated by this hybridization, we observe changes in his orientation towards science and his career choices. We use this case study to revisit methodological implications for understanding the role of “authentic science experiences” in science education.

Natural pedagogical conversations in high school students' internship     

Pei‐Ling Hsu  Wolff‐Michael Roth  Asit Mazumder 《科学教学研究杂志》2009,46(5):481-505

Many science educators encourage student experiences of “authentic” science by means of student participation in science‐related workplaces. Little research has been done, however, to investigate how “teaching” naturally occurs in such settings, where scientists or technicians normally do not have pedagogical training and generally do not have time (or value) receiving such training. This study examines how laboratory members without a pedagogical background or experience in teaching engage high school students during their internship activities. Drawing on conversation analysis, we analyze the minute‐by‐minute transactions that occurred while high school students participated in a leading environmental science laboratory. We find that the participation trajectory was based on demonstration‐practice‐connect (D‐P‐C) phases that continually recurred in the process of “doing” science. Concerning the transactional structures, we identify two basic conversation patterns—Initiate‐Clarify‐Reply (I‐C‐R) and Initiate‐Reply‐Clarify‐Reply (I‐R‐C‐R)—that do not only differ from the well‐known Initiate‐Reply‐Evaluate (I‐R‐E) patterns previously observed in science classrooms, but also could be combined to constitute more complex patterns. With respect to the organization of natural pedagogical conversations, we find that there were not only of preferred and dispreferred modes of responding but also ambiguous dispreferred modes; and the formulating organization not only includes self‐formulating but also other‐formulating. These natural pedagogical conversations helped, on the one hand, students to clarify their understanding and, on the other hand, technicians (or teachers) to teach toward different needs for different students in different contexts. © 2009 Wiley Periodicals, Inc.

Theorizing scientific literacy in the wild     

Michiel van Eijck  Wolff-Michael Roth 《Educational Research Review》2010,5(2):184-194

The purpose of this review paper is to contribute to the effort of rethinking scientific literacy in a form that is appropriate for describing and theorizing its occurrence “in the wild,” that is, in the everyday world that we share with others (as opposed to testing situations in classrooms and laboratories). Consistent with our commitment to practice, we exemplify relevant theories of everyday cognition with a case study of scientific literacy in the wild. Accordingly, we conceive scientific literacy as situated, distributed, and dynamic. We use this case study as a touchstone for reviewing the literature on scientific literacy as it has been developed over the past 50 years. Our review shows that sociocultural and cultural-historical activity theoretic models of knowing account for scientific literacy in the wild better than other theories. If the purpose of science education is to produce a scientifically literate citizenry, the question now can be asked what these models propose to frame school science and the possible trajectories that might lead to scientific literacy in the wild.  相似文献   

Engaging young children in collective curriculum design     

Maria Inês Mafra Goulart  Wolff-Michael Roth 《Cultural Studies of Science Education》2010,5(3):533-562

In this study we investigate how 5-year-old children in Brazil and their teachers collectively design science curriculum. More specifically, we develop an agency|structure dialectic as a framework to describe this collective praxis in which science curriculum may emerge as the result of children–teacher transactions rather than as a result of being predetermined and controlled by the latter. We draw on a cultural-historical approach and on the theory of structure and agency to analyze the events showing the complexity of the activity inside a classroom of very young children by science education standards. Data were collected in the context of a science unit in an early-childhood education program in Belo Horizonte. Our study suggests that (a) throughout the movement of agency|passivity || schema|resources one can observe participative thinking, a form of collective consciousness that arises in and from lived experience; (b) learning is a process in which a group is invested in searching for solutions while they create schemas and rearrange resources to evolve a new structure; and (c) the emergent curriculum is a powerful form of praxis that develops children’s participation from early childhood on.  相似文献   

The invisible subject in educational science     

Wolff-Michael Roth 《课程研究杂志》2018,50(3):315-332

The crisis of education frequently is framed in terms of methods, where quantitative research is accused of making the subject invisible through quantification, whereas qualitative research is credited for the emphasis on subjectivity and the discursive construction of reality. Such formulations fail to take into account a long-standing critique that interpretive (constructivist) research, too, makes invisible the real, living subject who is coping with an inherently open life, placing in its stead a ratiocinating individual. In this article, an argument is made for a concrete educational science concerned with the person who is not only (agential) subject but also subject and subjected to the condition it contributes to producing. This subject never is in complete control over its condition, cannot ever know precisely what is currently happening, and at best witnesses rather than grasps or constructs what is going on. This viewpoint requires a rethinking of the subject in/of educational science. Such a project of rethinking the subject involves shifting the minimum units of analysis: from (inter-) action to transaction, from an experience [Erfahrung] to inchoate lived-experiencing [perezhivanie, Erleben], from entities and processes to dramatic events.  相似文献   

Presenter passion and presentation design on reviewer assessment and subsequent success: An empirical study of high technology proposal and business plan presentations     

Craig S. Galbraith  Alex F. DeNoble  Sanford B. Ehrlich  Alexandra Nadya Horowitz 《The Journal of High Technology Management Research》2013,24(1):53-63

We investigate two fundamental research questions related to the funding of early-stage technology enterprises. First, does presentation design, and the presenting entrepreneur's passion and preparedness, influence experts' assessment of the merit and commercialization potential of an emerging firm's technology? Second, are the entrepreneur's passion and preparedness during a formal presentation associated with future technology success? We analyze twenty-two video-taped presentations to a U.S. Department of Defense technology transfer and granting consortium, and track subsequent technology success. From the data it appears that both entrepreneurial passion and presentation design does influence expert assessment of a technology, and future commercialization success can be predicted to some extent by the level of entrepreneurial passion exhibited during the presentation.  相似文献
