The importance of phonological awareness for the future learning of written language has been widely recognized, but there is still some debate as to whether syllabic, intrasyllabic, and phonemic awareness are independent skills or manifestations of the same general skill. Consequently, the objective of this study was to test the independence of phonological awareness at the syllable, rhyme, and phoneme levels. The study involved the participation of 256 children in their last year of preschool. The children completed 18 phonological awareness tasks. Three models were tested: a one-factor model (phonological awareness), two-factor model (supraphonemic unit awareness and phonemic awareness) and three-factor model (syllabic, intrasyllabic, and phonemic awareness). The results indicated that the three-factor model had the best fit, suggesting the relative independence of syllable, rhyme, and phoneme awareness. These results have important implications for assessing and intervening in sound sensitivity and identification skills in the preschool period. 相似文献

In this paper we initially address the main categories of Marxism, illustrating how Vygotsky has appropriated them as mediational meta-theoretical tools for building concepts for his psychological approach. In order to investigate the influence of Marxism in cultural studies of science education, we make an account of how current research, sustained by Vygotsky’s original and successor theories, has been appropriating meta-theoretical categories of dialectical materialism. Once we identified Cultural Studies of Science Education as a journal that would probably concentrate papers that follow these perspectives, we decided to take it as the context of this study. In the process of selecting the corpus to be reviewed from the editions published from 2006 to 2011, we have found that 16 % of the articles that matched keywords denoting frameworks related to the Vygotskian tradition developed and appropriated the categories of dialectical materialism. The quality and originality of contemporary development of CHAT denote that this framework has been playing a very important role in recent expansion of Vygotskian approaches to research in science education. Among the papers that we considered to develop and appropriate Vygotskian frameworks, incompletion in the appropriation of meta-theoretical categories of dialectical materialism and the misusage of dialectics intertwined with dialogism were highlighted. Our findings suggest that overcoming these limitations can enhance political analysis of sociocultural phenomena in the context of science education. It also represents a strengthening of the role of dialectical materialism in expanding sociocultural perspectives toward a better articulation between individual and institutional-centered analyses. 相似文献

The rise in globalisation studies in comparative education places neo-institutional theory at the centre of many debates among comparative education researchers. However, uncertainty about how to interpret neo-institutional theory still persists among educational comparativists. With this uncertainty comes misinterpretation of its principles, variations and explanatory power. Two problematic misconceptions prevail: (1) the belief that the ‘world culture’ strand is the only version of neo-institutional theory applicable to comparative education research; and (2) the assumption that the global homogenisation of society, culture and schooling is a goal of researchers applying neo-institutional theory to comparative education phenomena. This article addresses these misconceptions, elucidating neo-institutional theory and its applicability to comparative education research. Our findings suggest that neo-institutional frameworks for comparative education research are useful, but that complementary approaches and methods are also necessary. 相似文献
