Learning science through technological design     

Wolff‐Michael Roth 《科学教学研究杂志》2001,38(7):768-790

In the course of a decade of research on learning in technology‐centered classrooms, my research group has gained considerable understanding of why and how students learn science by designing technology. In this article I briefly review two dimensions in which science and technology share fundamental similarities: (a) the production and transformation of representations and (b∥ the action‐oriented language describing the two domains. Because it is fundamentally problematic to derive what ought to happen in science classrooms from other dimensions, I provide three episodes to illustrate what and how students know and learn science during technological design activities. Episodes and analyses embody the two dimensions previously outlined. Because these episodes are representative of the database established during an extensive research program, I suggest there is sufficient ground for using and investigating science‐through‐technology curricula. © 2001 John Wiley & Sons, Inc.

Preschool children’s conceptions of water,molecule, and chemistry before and after participating in a playfully dramatized early childhood education activity     

Åkerblom  Annika  Součková  Daniela  Pramling  Niklas 《Cultural Studies of Science Education》2019,14(4):879-895

The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by Vygotsky’s cultural-historical perspective on concept formation. The empirical data consist of pre- and post-interviews with children and documentation of their participation in the intermediate activity. This documentation is used in the post-interviews as a mutual ground for talking with the children about what they remember and how they understand the activity they participated in and what the activity intended to illustrate. The results are presented in terms of three inductively generated categories: ‘everyday’, ‘experientially-based’, and ‘generalized experiences’ concepts, respectively. The implications of these findings for early childhood chemistry (science) education are discussed.

Integration of Scientific Competence into Gross Anatomy Teaching Using Poster Presentations: Feasibility and Perception among Medical Students     

Michael Schön  Konrad Steinestel  Doreen Spiegelburg  Annika Risch  Mira Seidel  Leon Schurr  Ulrich Kai Fassnacht  Nikola Golenhofen  Tobias Maria Böckers  Anja Böckers 《Anatomical sciences education》2022,15(1):89-101

Scientific competencies, as defined in the German competency framework, describe the ability to think independently and act scientifically which is a central component of medical education. This report describes integration of scientific competencies into anatomical teaching. Based on findings seen in two consecutive years of dissection courses, students worked on either a case report (n = 70) or an original research study (n = 6) in the format of a scientific poster while learning to use primary literature. Posters were evaluated by juror teams using standardized evaluation criteria. Student perception of the project was assessed by quantitative and qualitative data obtained from the faculty's course evaluation and an online-survey. Overall, students worked collaboratively and invested extra-time (median 3.0 hours) in poster creation. Primary literature was integrated in 90.8% of the posters. Overall poster quality was satisfactory (46.3 ± 8.5 [mean ± standard deviation] out of 72 points), but several insufficiencies were identified. Students integrated information gained from the donor's death certificate, post-mortem full-body computed tomography (CT) scan (22.4%), and histopathological workup (31.6%) in their case reports. Students responded positively about learning new scientific skills (median 4.0 on a six-point Likert scale), but free-text answers revealed that some students experienced the project as an extra burden in a demanding gross anatomy course. In summary, it was feasible to introduce students to scientific skills during the dissection course and to increase interest in science in approximately a third of the survey respondents. Further adjustments to ensure the posters' scientific quality might be necessary for the future.  相似文献

“It wouldn't be the same without nature”—The value of nature according to Finnish upper secondary school students     

Pia Sjöblom  Lili-Ann Wolff 《The Journal of environmental education》2017,48(5):322-333

This article describes an interview study on Finnish upper secondary school students' values of nature. Even if the Finnish adolescents' interest in nature has decreased, most of the interviewees in this study regarded nature as worthy of maintenance. They valued nature for its material, aesthetic, and recreational values, as well as its diversity and future value, and because of their holistic view of nature. The nature values of the students were complex. Therefore, we suggest education that supports their value development through deliberation, authentic involvement, and outdoor activities.  相似文献   

Relational Maintenance Strategies During the Post Sex Time Interval     

Amanda Denes  Anuraj Dhillon  Annika C. Speer 《Communication quarterly》2017,65(3):307-332

The present study contributes to a growing line of research exploring the role of post sex communication in building and sustaining romantic relationships. More specifically, this study explores the use of relational maintenance strategies during the post sex time interval (PSTI). One-hundred and fifty-two individuals completed surveys after sexual activity and indicated the relational maintenance strategies they enacted during the PSTI. Results revealed that individuals enact the strategies of positivity and assurances to the greatest degree during the PSTI. Furthermore, extending the post sex disclosures model, results revealed that orgasm predicted differences in the use of assurances during the PSTI and that the strategy of assurances mediated the association between orgasm and several relationship outcomes (i.e., liking, commitment, control mutuality, and satisfaction). These findings suggest that individuals may use the PSTI as a time to reinforce their commitments to their partners, and that such behavior is associated with characteristics of the sexual episode and relationship outcomes. The implications of these findings for research on relational maintenance and post sex behavior are discussed.  相似文献   

Cultural diversity in science education through Novelization: Against the Epicization of science and cultural centralization     

Michiel van Eijck  Wolff‐Michael Roth 《科学教学研究杂志》2011,48(7):824-847

Science educators are confronted with the challenge to accommodate in their classes an increasing cultural and linguistic diversity that results from globalization. Challenged by the call to work towards valuing and keeping this diversity in the face of the canonical nature of school science discourse, we propose a new way of thinking about and investigating these problems. Drawing on the work of Mikhail Bakhtin, we articulate epicization and novelization as concepts that allow us to understand, respectively, the processes of (a) centralizing and homogenizing culture and language and (b) pluralizing culture and language. We present and analyze three examples that exhibit how existing mundane science education practices tend, by means of epicization, towards a unitary language and to cultural centralization. We then propose novelization as a way for thinking the opening up of science education by interacting with and incorporating alternative forms of knowing that arise from cultural diversity. © 2011 Wiley Periodicals, Inc.

Public participation: democratic ideal or pragmatic tool? The cases of GM foods and functional foods     

Nielsen AP  Lassen J  Sandøe P 《Public understanding of science (Bristol, England)》2011,20(2):163-178

Over recent decades, public participation initiatives have been employed across Europe often with a focus on science and technology issues. In the area of new food technologies most participation initiatives have centered on genetically modified foods. By contrast, in the area of functional foods--where significant EU legislation was recently passed--we have seen no initiatives towards public inclusion. This applies also for Denmark, the country which is the focus of this article. Based on an interview study with members of the Danish parliament the article examines why such considerable differences exist between initiatives to involve the public, and it challenges the role that public participation plays in Danish politics. The main claim made in the article is that although politicians argue for the value and relevance of public participation their willingness to initiate participatory processes is overruled by their concern with playing by the rules of the political game.  相似文献   

Integrating multidisciplinary engineering knowledge     

Karin Wolff  Kathy Luckett 《Teaching in Higher Education》2013,18(1):78-92

In order to design two distinct engineering qualification levels for an existing University of Technology programme, empirical evidence based on the current diploma is necessary to illuminate the nature of and the relationship between the contextual and conceptual elements underpinning a multidisciplinary engineering curriculum. The increasing focus on contextual application could result in decreasing opportunities to develop the conceptual disciplinary grasp required for a dynamic, emerging region at the forefront of technological innovation. Using the theoretical tools of Bernstein and Maton to analyse final year student practice, the research addresses the question of how multidisciplinary knowledge is integrated by students, and what this reveals about the nature of such knowledge. The paper presents a conceptualisation of multidisciplinary knowledge integration practices as a dynamic process along two axes simultaneously, shifting between different forms and levels of conceptual and contextual knowledge.  相似文献
