In this study we investigated junior high school students' processes of argumentation and cognitive development in science and socioscientific lessons. Detailed studies of the relationship between argumentation and the development of scientific knowledge are rare. Using video and audio documents of small group and classroom discussions, the quality and frequency of students' argumentation was analyzed using a schema based on the work of Toulmin ( 1958 ). In parallel, students' development and use of scientific knowledge was also investigated, drawing on a schema for determining the content and level of abstraction of students' meaning‐making. These two complementary analyses enabled an exploration of their impact on each other. The microanalysis of student discourse showed that: (a) when engaging in argumentation students draw on their prior experiences and knowledge; (b) such activity enables students to consolidate their existing knowledge and elaborate their science understanding at relatively high levels of abstraction. The results also suggest that students can acquire a higher quality of argumentation that consists of well‐grounded knowledge with a relatively low level of abstraction. The findings further suggest that the main indicator of whether or not a high quality of argument is likely to be attained is students' familiarity and understanding of the content of the task. The major implication of this work for developing argumentation in the classroom is the need to consider the nature and extent of students' content‐specific experiences and knowledge prior to asking them to engage in argumentation. © 2007 Wiley Periodicals, Inc.

Kim and Roth (this issue) purport to draw on the social-psychological theory of L. S. Vygotsky in order to investigate social relations in children’s argumentation in science topics. The authors argue that the argumentation framework offered by Stephen Toulmin is limited in addressing social relations. The authors thus criticize Toulmin’s Argument Pattern (TAP) as an analytical tool and propose to investigate the genesis of evidence-related practices (especially burden of proof) in second- and third-grade children by studying dialogical interactions. In this paper, I illustrate how Toulmin’s framework can contribute to (a) the study of “social relations”, and (b) provide an example utilizing a theoretical framework on social relations, namely Engeström’s Activity Theory framework, and (c) describe how we have used the Activity Theory along with TAP in order to understand the development of argumentation in the practices of science educators. Overall, I will argue that TAP is not inherently incapable of addressing social relational aspects of argumentation in science education but rather that science education researchers can transform theoretical tools such as Toulmin’s framework intended for other purposes for use in science education research. 相似文献

This paper describes how the patriarchal structure of Japanese society and its notions of women, femininity, and gendered
stereotypes produced strong cultural barriers to increasing the participation of females in science education. Baseline data
on attitudes toward science and the perceptions of gender issues in science education, academic major and career choice were
collected from 175 university students (124 female, 51 male). Students responded to a Likert scale that included the option
“I don't understand the question”. All respondents took advantage of the option for items related to gender issues. On some
items up to 67% of the males responded that they did not understand the question. Females in science choosing this option
did not exceed 19%. In Japan, gender is an invisible, pervasive construct that impacts females' participation in science and
science education. In other ways, attitudes toward science among Japanese students mirrored those found in the United States
and in other countries. Respondents held the most favorable views of science when they were in elementary school and females
preferred biology while males preferred the physical sciences. The exception to the Western pattern of liking science and
science teachers is that male non-science majors rather than female non-science majors reported poor academic performance
in elementary school, declining attitudes in middle school, and they held the most negative attitudes toward their science
teacher and science subjects. 相似文献

In this review essay I respond to issues raised in Mijung Kim and Wolff-Michael Roth’s paper titled “Dialogical argumentation in elementary science classrooms”, which presents a study dealing with dialogical argumentation in early elementary school classrooms. Since there is very limited research on lower primary school students’ argumentation in school science, their paper makes a contribution to research on children’s argumentation skills. In this response, I focus on two main issues to extend the discussion in Kim and Roth’s paper: (a) methodological issues including conducting a quantitative study on children’s argumentation levels and focusing on children’s written argumentation in addition to their dialogical argumentation, and (b) investigating children’s conceptual understanding along with their argumentation levels. Kim and Roth emphasize the difficulty in determining the level of children’s argumentation through the Toulmin’s Argument Pattern and lack of high level arguments by children due to their difficulties in writing texts. Regarding these methodological issues, I suggest designing quantitative research on coding children’s argument levels because such research could potentially provide important findings on children’s argumentation. Furthermore, I discuss alternative written products including posters, figures, or pictures generated by children in order to trace children’s arguments, and finally articulating argumentation and conceptual understanding of children. 相似文献

This study aimed at investigating differential effects between group counselling and group guidance in conducting a ‘Coping
with Stress Training Program’ for 24 Turkish university students. The dependent variables were coping with stress, irrational
beliefs and optimism. A 3 × 2 design (treatment sequence by repeated measures) was applied. As a result of the treatment no
significant difference was observed between the two experimental groups in any of the variables tested in the study; however,
both experimental groups differed significantly from a control group in respect to coping with stress. With regard to the
within-group comparisons, irrational belief tendencies in both experimental groups decreased significantly, while the level
of optimism of the counselling group and the problem-focused stress coping tendencies of the guidance group increased significantly.
Based on the findings, it was considered that the program for developing coping skills for stress might best be implemented
in a group guidance format especially in Turkey where there are limited physical resources, a low number of staff to run programs
and a high number of students in need of help. 相似文献

The inclusion of Nature of Science (NOS) in the science curriculum has been advocated around the world for several decades. One way of defining NOS is related to the family resemblance approach (FRA). The family resemblance idea was originally described by Wittgenstein. Subsequently, philosophers and educators have applied Wittgenstein’s idea to problems of their own disciplines. For example, Irzik and Nola adapted Wittgenstein’s generic definition of the family resemblance idea to NOS, while Erduran and Dagher reconceptualized Irzik and Nola’s FRA-to-NOS by synthesizing educational applications by drawing on perspectives from science education research. In this article, we use the terminology of “Reconceptualized FRA-to-NOS (RFN)” to refer to Erduran and Dagher’s FRA version which offers an educational account inclusive of knowledge about pedagogical, instructional, curricular and assessment issues in science education. Our motivation for making this distinction is rooted in the need to clarify the various accounts of the family resemblance idea.The key components of the RFN include the aims and values of science, methods and methodological rules, scientific practices, scientific knowledge as well as the social-institutional dimensions of science including the social ethos, certification, and power relations. We investigate the potential of RFN in facilitating curriculum analysis and in determining the gaps related to NOS in the curriculum. We analyze two Turkish science curricula published 7 years apart and illustrate how RFN can contribute not only to the analysis of science curriculum itself but also to trends in science curriculum development. Furthermore, we present an analysis of documents from USA and Ireland and contrast them to the Turkish curricula thereby illustrating some trends in the coverage of RFN categories. The results indicate that while both Turkish curricula contain statements that identify science as a cognitive-epistemic system, they underemphasize science as a social-institutional system. The comparison analysis shows results such as the “scientific ethos” category being mentioned by the Irish curriculum while “social organizations and interactions” category being mentioned by the Turkish curriculum. In all documents, there was no overall coherence to NOS as a holistic narrative that would be inclusive of the various RFN categories simultaneously. The article contributes to the framing of NOS from a family resemblance perspective and highlights how RFN categories can be used as analytical tools. 相似文献

Traditional applications of history and philosophy of science in chemistry education have concentrated on the teaching and learning of history of chemistry. In this paper, the recent emergence of philosophy of chemistry as a distinct field is reported. The implications of this new domain for chemistry education are explored in the context of chemical models. Trends in the treatment of models in chemistry education highlights the need for reconceptualizing the teaching and learning of chemistry to embrace chemical epistemology, a potential contribution by philosophy of chemistry. 相似文献
