Progression in Ethical Reasoning When Addressing Socio-scientific Issues in Biotechnology     

Birgitta Berne 《International Journal of Science Education》2013,35(17):2958-2977

This article reports on the outcomes of an intervention in a Swedish school in which the author, a teacher-researcher, sought to develop students' (14–15 years old) ethical reasoning in science through the use of peer discussions about socio-scientific issues. Prior to the student discussions various prompts were used to highlight different aspects of the issues. In addition, students were given time to search for further information themselves. Analysis of students' written arguments, from the beginning of the intervention and afterwards, suggests that many students seem to be moving away from their use of everyday language towards using scientific concepts in their arguments. In addition, they moved from considering cloning and ‘designer babies’ solely in terms of the present to considering them in terms of the future. Furthermore, the students started to approach the issues in additional ways using not only consequentialism but also the approaches of virtue ethics, and rights and duties. Students' progression in ethical reasoning could be related to the characteristics of the interactions in peer discussions as students who critically and constructively argued with each other's ideas, and challenged each other's claims, made progress in more aspects of ethical reasoning than students merely using cumulative talk. As such, the work provides valuable indications for the importance of introducing peer discussions and debates about SSIs in connection to biotechnology into the teaching of science in schools.  相似文献   

Constraints to Changing Pedagogical Practices in Higher Education: An example from Japanese lesson study     

Kadir Demir  Camille Sutton-Brown  Charlene Czerniak 《International Journal of Science Education》2013,35(11):1709-1739

This article describes a qualitative study of college mathematics and science faculty (n?=?6) and their engagement in a reform-based program, Japanese lesson study (LS), to change their teaching practices. LS is a process in which a team of four to six teachers jointly design, teach, observe, analyze, and revise a single class lesson. A series of semi-structured, open-ended, interviews was completed with each of the faculty participants. Two sets of assertions were developed from analyses of the data and examples and explanations corroborating each assertion are provided. The results of the study identified issues related to organizational and faculty changes that need to be addressed if faculty responses to pedagogical innovations are to succeed. Implications of the findings for practice and future research are discussed.  相似文献   

Students’ Representations of Scientific Practice during a Science Internship: Reflections from an activity‐theoretic perspective     

Pei‐Ling Hsu  Michiel van Eijck  Wolff‐Michael Roth 《International Journal of Science Education》2013,35(9):1243-1266

Working at scientists’ elbows is one suggestion that educators make to improve science education, because such “authentic experiences” provide students with various types of science knowledge. However, there is an ongoing debate in the literature about the assumption that authentic science activities can enhance students’ understandings of scientific practice. The purpose of the study is to further address the debate in terms of the ethnographic data collected during an internship programme for high school students right through to their public presentations at the end. Drawing on activity theory to analyse these presentations, we found that students presented scientific practice as accomplished by individual personnel without collaboration in the laboratory. However, our ethnographic data of their internship interaction show that students have had conversations about the complex collaborations within and outside the laboratory. This phenomenon leads us to claim that students experienced authentic science in their internships, but their subsequent representations of authentic science are incomplete. That is, participating in authentic science internships and reporting scientific practice are embedded activities that constitute different goals and conditions rather than unrefracted reflections of one another. The debate on the influence on students’ understanding of science practice is not simply related to situating students in authentic science contexts, but also related to students’ values and ideology of reporting their understanding of and about science. To help students see these “invisible” moments of science practice is therefore crucial. We make suggestions for how the invisible in and of authentic science may be made visible.  相似文献   

A Framework for Re‐thinking Learning in Science from Recent Cognitive Science Perspectives     

Russell Tytler  Vaughan Prain 《International Journal of Science Education》2013,35(15):2055-2078

Recent accounts by cognitive scientists of factors affecting cognition imply the need to reconsider current dominant conceptual theories about science learning. These new accounts emphasize the role of context, embodied practices, and narrative‐based representation rather than learners’ cognitive constructs. In this paper we analyse data from a longitudinal study of primary school children’s learning to outline a framework based on these contemporary accounts and to delineate key points of difference from conceptual change perspectives. The findings suggest this framework provides strong theoretical and practical insights into how children learn and the key role of representational negotiation in this learning. We argue that the nature and process of conceptual change can be re‐interpreted in terms of the development of students’ representational resources.  相似文献   

Identifying secondary-school students’ difficulties when reading visual representations displayed in physics simulations     

Umesh Dewnarain Ramnarain 《International Journal of Science Education》2013,35(10):1353-1371

The apartheid policies in South Africa had a marked influence on the accessibility and quality of school science experienced by the different race groups. African learners in particular were seriously disadvantaged in this regard. The issues of equity and redress were foremost in transformation of the education system, and the accompanying curriculum reform. This paper reports on equity in terms of equality of outputs and equality of inputs in South African school science, with a particular focus on the implementation of practical science investigations. This was a qualitative case study of two teachers on their implementation of science investigations at two schools, one a township school, previously designated for black children, and the other a former Model C school, previously reserved for white children. My study was guided by the curriculum implementation framework by Rogan and Grayson in trying to understand the practice of these teachers at schools located in contextually diverse communities. The framework helped profile the implementation of science investigations and also enabled me to explore the factors which are able to support or hinder this implementation.  相似文献   

Secondary Students’ Understanding of Basic Ideas of Special Relativity     

Kyriaki Dimitriadi  Krystallia Halkia 《International Journal of Science Education》2013,35(16):2565-2582

A major topic that has marked ‘modern physics’ is the theory of special relativity (TSR). The present work focuses on the possibility of teaching the basic ideas of the TSR to students at the upper secondary level in such a way that they are able to understand and learn the ideas. Its aim is to investigate students' learning processes towards the two axioms of the theory (the principle of relativity and the invariance of the speed of light) and their consequences (the relativity of simultaneity, time dilation and length contraction). Based on an analysis of physics college textbooks, on a review of the relevant bibliography and on a pilot study, a teaching and learning sequence consisting of five sessions was developed. To collect the data, experimental interviews (the so-called teaching experiment) were used. The teaching experiment may be viewed as a Piagetian clinical interview that is deliberately employed as a teaching and learning situation. The sample consisted of 40 10th grade students (aged 15–16). The data were collected by taping and transcribing the ‘interviews’, as well as from two open-ended questionnaires filled out by each student, one before and the other after the sessions. Methods of qualitative content analysis were applied. The results show that upper secondary education students are able to cope with the basic ideas of the TSR, but there are some difficulties caused by the following student conceptions: (a) there is an absolute frame of reference, (b) objects have fixed properties and (c) the way events happen is independent of what the observers perceive.  相似文献   

Comment on Speed-Accuracy Tradeoff during Response Preparation (Cauraugh, 1990)     

T. Gilmour Reeve  Robert W. Proctor 《Research quarterly for exercise and sport》2013,84(1):118-120

In this study, I conducted focus group interviews with 21 Arab American college students (9 men, 12 women; 9 Muslims, 12 non-Muslims), who were selected for extreme manifestation of religiosity or acculturation, to explore their beliefs and attitudes toward socioecological (SE) factors that facilitated and hindered their individual physical activity (PA) and body composition (I also considered body image and food and eating behavior). To analyze responses, I used a combination of deductive coding, which used levels of the SE model and demographic variable groupings, and inductive coding, to search for common themes among participants within and between research questions. Results revealed that (a) the context of physical activity participation differed by gender; (b) ideal body image was conflicted and varied by gender; and (c) consumption of cultural foods diminished along with Arab social customs related to eating. Interpersonal and cultural/community levels of the SE model were identified as primary influences, with parents regulating and instilling values backed by cultural norms to preserve Arab identity, especially in women. Finally, I identified an indeterminate adjustment period, during which immigrants transitioned between physical activity purpose/form in the Middle East and the United States.  相似文献   

Intercultural Interaction at a Multicultural University: Students' Definitions and Sensemakings of Intercultural Interaction     

《Journal of International and Intercultural Communication》2013,6(4):304-324

Abstract

This essay examines how racially or ethnically different students define, make sense of, and evaluate intercultural interaction at the multicultural university. Eighty qualitative in-depth interviews were conducted with university students of varied backgrounds. These interview sessions access students' definitions, sensemakings, and experiences of on-campus intercultural interaction as it has played out in their lives. The findings demonstrate that interviewees equate intercultural interaction with being present in demographically diverse settings. Moreover, this study reveals that definitions and sensemakings of intercultural interaction vary among interviewees primarily based on their racial or ethnic background. Latino/a, Black/African American, White/European American, and Asian American interviewees define and make sense of intercultural interactions in culturally specific ways and in relation to their historical experiences.  相似文献   

Researching embodiment in movement contexts: a phenomenological approach     

Øyvind F. Standal  Gunn Engelsrud 《Sport, Education and Society》2013,18(2):154-166

This article takes a phenomenological approach to understanding embodiment in relation to teaching and learning taking place in movement contexts. Recently a number of studies have pointed to the potential that phenomenology has to understand the meanings and experiences of moving subjects. By presenting two examples of our own work on embodied learning, and discussing these in light of a distinction between phenomenology as philosophy and as methodological orientation, our aim is to move beyond the recent celebration of the potential of phenomenology, and show concretely and practically how phenomenological approaches to embodiment can be performed. We hold that it is necessary to give the notion of embodiment a form, content and substance, which is informed by empirical work.  相似文献
