Not realizing the ontological difference between anxiety and fear has led researchers to misinterpret what they are “measuring” when investigating the effects that these phenomena have on communicative ability. A phenomenology of anxiety elucidates this ontological difference and clarifies how anxiety and fear are experienced in communication situations. 相似文献

MyScience is a primary science education initiative in which being in a community of practice is integral to the learning process. One component of this initiative involves professional scientists interacting with primary school communities which are navigating their way towards sustainable ‘communities of practice’ around the ‘domain’ of ‘investigating scientifically’. This paper describes the ongoing journey to date of eleven scientists (six astronomers and five engineers) who actively participated in MyScience over an extended period. Their views of interactions with teachers and students were analysed using attributes associated with both ‘communities of practice’ and the ‘nature of science’. Findings reveal new understandings about the evolving characteristics associated with the development of such school-community collaborations as well as affordances and barriers that may influence their further growth. The influence of these scientists’ own ‘community of science practices’ may account for some of the findings. Implications for science teaching and learning in primary school community of practice settings are discussed. 相似文献

When and how do infants learn color words? It is generally supposed that color words are learned late and with a great deal of difficulty. By examining infant language surveys in British English and 11 other languages, this study shows that color word learning occurs earlier than has been previously suggested and that the order of acquisition of color words is similar in related languages. This study also demonstrates that frequency and syllabic complexity can be used to predict variability in infant color word learning across languages. In light of recent evidence indicating that color categories have universal biological foundations, these findings suggest that infants’ experience and linguistic exposure drive their shift to culturally and linguistically mediated adult-like understandings of color words. 相似文献

This article examines the nature of the gap in household telephone penetration among Whites, Blacks, and Hispanics. By analyzing historic and current penetration levels of the radio, television, and telephone, it suggests that most information technology gaps are amalgamations of smaller socioeconomic trends and can be discerned and reduced only with careful historical analysis of both technology choices and living patterns. It proposes localized universal service strategies, since the penetration gaps are affected by a complex array of factors more particular to localities than to the country as a whole and as such must be investigated with rigor and caution if progress toward the elimination of penetration gaps is to occur. 相似文献
