The purpose of the study was to examine the efficacy of a 4-week dialogic reading intervention with rural Bangladeshi preschoolers with the intention of increasing their expressive vocabulary. Eighty preschoolers randomly selected from five preschools participated in the 4-week program. Their expressive vocabulary, measured in terms of definitions, was tested on 170 challenging words before and after the program and compared with that of control children who participated in the regular language program. Both groups were read in Bangla eight children's storybooks with illustrations, but the dialogic reading teacher was given a set of “wh” and definitional questions to enhance children's verbal participation. The mean vocabulary scores of dialogic program children increased from 26% to 54% whereas the control children remained at the same level. Results are discussed in terms of the successful application of dialogic reading to low-resource preschools. 相似文献

Radiocarbon dating is, and remains, one of the most powerful methods of dating archaeological artefacts. Initially, it was assumed that the carbon-14 content of atmospheric carbon dioxide had remained constant, but latterly it has been shown that this assumption is not valid. It has now proved possible, mainly by correlation with tree-growth rings, to measure historic fluctuations in carbon-14 content and to make the necessary corrections—of up to one thousand years—to the conventionally calculated dates. 相似文献

Practical and theoretical shortcomings of an approach to moral education based on the development of moral reasoning are noted and the alternative of promoting the virtues is considered. The identification of appropriate virtues with modes of commitment and conduct supportive of a particular way of life is held to raise the further question of why a particular way of life should be favoured, and how our own way of life should be characterised. This latter, permitting social and geographical mobility, anonymity and value pluralism, is contrasted with that of smaller, more traditional communities paradigmatic of communitarian ethics. An ethic of respect for equal freedom is held to be compatible with the current nature of society and to be favoured by the virtue of appropriate self-assertion. The educational implications of such a conclusion are explored. 相似文献
