This study was designed to investigate the relationship between students' views of the nature of scientific knowledge and
their own learning of physics, and the evolution of this relationship over time. Twenty-three students enrolled in a physics
course that emphasised laboratory work and discussions about the nature of science. Over a 15-month period, an extensive data
base was established including student essays and interviews regarding their views of the nature of science and teaching and
learning of physics. As part of an extensive data generation, students read a book on the epistemology of physics, wrote reflective
essays, and subsequently discussed the epistemology of physics in class. Two intensive case studies are used to illustrate
our understanding of students' views over time. Changes in students' views concerning the nature of scientific knowledge and
of the science teaching and learning process, which were not always complementary, are described with the aid of a model.
The findings of this research have direct relevance to the planning and implementation of science courses in which the development
of understandings of the nature of science is an objective. 相似文献

The school-age population in North America is characterized by increasing linguistic, cultural, and ethnic diversity. The authors argue that non-mainstream students do not perform as well in schools as mainstream students (predominantly whilte, middle-class English speakers) because they are not equitably served by the educational system. They explore some of the complexities of educational equity and consider equity issues in the literacy education of language minority students from four different perspectives: individual student characteristics, sociocultural factors, language issues, and instructional issues. In support of their position, they examine each of these areas in turn, providing illustrations and analysis. They conclude with several principles upon which to build practices to make literacy education more equitable for all students. 相似文献

Recent Chinese migrant students from Taiwan studying science in two Australian secondary schools were found to explain the
meanings of selected science concept labels in English by translating from Chinese. The research strategy involved interviewing
the students concerning their recognition and comprehension of the science concept labels firstly in Chinese and then in English.
Mean recognition and comprehension scores were higher in Chinese than in English, with indications that Chinese language and
science knowledge learnt in Chinese deteriorated with increasing time of residence in Australia. Rudimentary signs of the
students being able to switch between Chinese and English knowledge bases in science were also found. Implications for teaching
science to ESL students and suggestions for further research are discussed. 相似文献

We analyse and explore, in the form of dialogues and metalogues questions about the dialogic nature of beliefs and students
belief talk about the nature of science and scientific knowledge. Following recent advances in discursive psychology, this
study focuses not on students' claims but on the discursive resources and dialogical practices that support the particular
claims they make. We argue that students' discourse is better understood as a textual bricolage that is sensitive to conversational
context, common sense, interpretive repertoires, and textual resources available in the conversational situation. Our text
is reflexive as it embodies the discursive construction of knowledge and undercuts any claims to authoritative knowledge.
The very conception of “belief” is itself an expression or construction from within the mundane idiom.... We learn to use
“belief” in conditions when the “objective facts” are unknown or problematic and we want to indicate the tenuous character
of our claim.... The notion of “real world” or “objective reality” is embedded in an extensive, pervasive language game which
includes as an intelligible move or possibility the use of the very concept of “belief” itself. (Pollner, 1987, p. 21) 相似文献

Maintaining the reversibility of foldings: Making the ethics (politics) of information technology visible 总被引:1,自引:0,他引:1
Lucas D. Introna 《Ethics and Information Technology》2007,9(1):11-25
This paper will address the question of the morality of technology. I believe this is an important question for our contemporary
society in which technology, especially information technology, is increasingly becoming the default mode of social ordering.
I want to suggest that the conventional manner of conceptualising the morality of technology is inadequate – even dangerous.
The conventional view of technology is that technology represents technical means to achieve social ends. Thus, the moral
problem of technology, from this perspective, is the way in which the given technical means are applied to particular (good
or bad) social ends. In opposition to this I want to suggest that the assumed separation, of this approach, between technical
means and social ends are inappropriate. It only serves to hide the most important political and ethical dimensions of technology.
I want to suggest that the morality of technology is much more embedded and implicit than such a view would suggest. In order
to critique this approach I will draw on phenomenology and the more recent work of Bruno Latour. With these intellectual resources
in mind I will propose disclosive ethics as a way to make the morality of technology visible. I will give a brief account
of this approach and show how it might guide our␣understanding of the ethics and politics of technology by considering two
examples of contemporary information technology: search engines and plagiarism detection systems. 相似文献
