Technology Education offers an authentic and invaluable range of skills, knowledge, capabilities, contexts and ways of thinking for learners in the 21st century. However, it is recognised that it occupies a comparatively less defined and more fragile curricular position than associated, but longer established, subjects such as Mathematics and Science. While recognising that no single factor lies behind such a condition, this paper draws upon thinking in the philosophy of technology, technology education and the ontology of artefacts to argue that transformation may be considered as an epistemic source for technology in a similar way to ‘proof’ within Mathematics and ‘interpretation’ within Science. Encapsulating technology's intimate relationship with materials, it is ultimately argued that the transformation of a technical artefact from an ill‐defined into a well‐defined ontological state constitutes a prime source of technological knowledge for pupils. Moreover, it provides an alternative route into further consideration about the nature of the domain, epistemology and curricular identity of the subject.  相似文献

Abstract

The gender sexual politics of Liu Yu‐hsiu has been pivotal in the hegemonic ascendancy of Taiwan state feminism in recent years. Through an examination of Liu’s psychoanalytically mediated essays of cultural criticism, this article traces the contour of Liu’s sexual imaginary within the context of 1990s feminist and queer politics. Liu’s modernising project of gender equality, I argue, upholds heterosexual monogamy as a feminist ideal that seeks to purge all the masculine ills, including perversion and promiscuity. Meanwhile, queers and prostitutes come to be figured as the very negativity that must be repressed. Yet, like the Lacanian Real, they impinge on the symbolic order that Liu ordains as they thwart her desire to civilise sex.  相似文献

Abstract

Many people remember their language lessons from their secondary schooldays as tedious and ineffective. Although the emphasis in language teaching has shifted from the passive skills (reading, listening) to the active skills of speaking and writing, the result after many years of hard work is often disappointing. Learning a language in a classroom environment is extremely difficult. There is no real need to speak or write. Teachers are not interested in the contents of what their students are saying or writing but in the correctness. There is not enough time for the individual student to manipulate and practise what he or she has learned. Motivation is low. Obviously, computers cannot solve these problems. However, they can be used to create a more stimulating environment in which students are given authentic tasks that require a real use of language. If computers are used for practice and drill only, we are missing out on a valuable contribution to language learning and teaching.  相似文献

The aim of the present study was to examine the spelling development of Greek‐speaking children in the early school grades. Although Greek orthography is regular for reading, it is much less transparent as far as spelling is concerned. Spelling development was investigated using a word spelling task designed to explore the effects of word length, familiarity and spelling regularity. One hundred and fifty normally developing primary school children living in Cyprus took part in the study. Results suggest that the children employed both phonological and lexical strategies in spelling Greek words. Results indicated that sub‐lexical procedures were more marked for younger children, whereas lexical processing was employed more widely by older children. The findings are interpreted in terms of stage developmental models.  相似文献

Today’s society is continuously coping with sustainability‐related complex issues in the Science‐Technology‐Environment‐Society (STES) interfaces. In those contexts, the need and relevance of the development of students’ higher‐order cognitive skills (HOCS) such as question‐asking, critical‐thinking, problem‐solving and decision‐making capabilities within science teaching have been argued by several science educators for decades. Three main objectives guided this study: (1) to establish “base lines” for HOCS capabilities of 10th grade students (n = 264) in the Israeli educational system; (2) to delineate within this population, two different groups with respect to their decision‐making capability, science‐oriented (n = 142) and non‐science (n = 122) students, Groups A and B, respectively; and (3) to assess the pre‐post development/change of students’ decision‐making capabilities via STES‐oriented HOCS‐promoting curricular modules entitled Science, Technology and Environment in Modern Society (STEMS). A specially developed and validated decision‐making questionnaire was used for obtaining a research‐based response to the guiding research questions. Our findings suggest that a long‐term persistent application of purposed decision‐making, promoting teaching strategies, is needed in order to succeed in affecting, positively, high‐school students’ decision‐making ability. The need for science teachers’ involvement in the development of their students’ HOCS capabilities is thus apparent.  相似文献

Abstract

This paper gives an overview of the problems involved in visualizing humans in a three‐dimensional scene, and looks at the history and development of human shape modelling, human motion control, and modelling of human characteristics and clothing to produce computer‐generated actors.  相似文献

A study of Norwegian science textbooks for grade 8 indicates an individualistic image of science where individual scientists are discovering truth, through experiment. Scientific rationality is grounded in procedures of inquiry alone and not in debate and argumentation within scientific communities. The communal aspects of science tend to become visible in historical examples where science did not function properly due to prejudices or ignorance. Furthermore, science proper and school science are not differentiated between, and 'scientific knowledge about nature' and 'nature' are one and the same. The discourse identified is well suited to provide students with broad and general knowledge about natural and everyday phenomena. However, it is less suitable for teaching about the scientific enterprise in contemporary society. This is worrying for students' scientific literacy as future adults, as this dimension is essential for understanding the nature of science and for democratic citizenship in socio-scientific issues.  相似文献
