This article explores ways in which children's picture books form networks of relationships, and their implications for readers and classroom teachers. In this exploration, reading is seen to involve making connections within and beyond the text at hand. These connections, evoked differently across readers, shape readers' interpretations of text. Many possible meanings may arise from just one text, reinforcing the idea that no single correct meaning resides in a text. This article demonstrates tools for exploring textual connections with readers, and the value of such explorations for opening‐up reader interpretations of a text. 相似文献

This article discusses some findings from a small‐scale investigation of children's gendered beliefs and behaviours in a Korean kindergarten which was attempting to challenge gender stereotyping through the anti‐bias intervention of a ‘cooking curriculum’. A sample of 14 children, some with ‘working’ mothers and some with ‘housewife’ mothers, was observed for two months, and informally interviewed on several occasions. The children's mothers were also interviewed. The findings are situated in the context of the changing, but still traditional, culture of Korean society, as well as in the contexts of early childhood education and theories of gender acquisition. They confirm that, although children are highly likely to reproduce the beliefs current in their home environment, they are open to reconstructing these views when actively challenged to consider alternatives, either by the school curriculum or by engaging in debate with a researcher or practitioner. The nature of the ‘alternative’ views available may however be problematic. 相似文献

文章对某作者两篇坚持文艺从属于政治、服务于政治的观点的文章进行了商榷和辩难,认为它的观点既违背了马克思主义历史唯物主义,又违背了马克思主义辩证唯物主义。因此对文章说什么放弃“从属”论是什么“重大理论问题上的速误”等说法进行了反驳和否定,指出只有坚持邓小平的科学论断,才能迎接社会主义文学艺术的更大繁荣兴旺。 相似文献

This article provides a rationale for using literature in the classroom to explore conceptions of curriculum and teaching. We discuss a number of exemplars from children’s and young adult fiction, both mainstream and less well known; offer a taxonomy for categorizing the range of visions of curriculum and teaching in the literature; and describe the responses of a group of middle school students to a unit that examined schooling in literature. We argue that reading literature which addresses student experiences in school can help students make sense of those experiences and, more importantly, open their minds to ideas about teaching and schooling that they otherwise might never have considered.John Kornfeld is Professor and Director of Graduate Studies in the School of Education at Sonoma State University. His research in curriculum, children’s literature, school/ university collaboration, and the politics of schooling has been published in such journals as Theory into Practice, Social Education, and Theory and Research in Social Education.Laurie Prothro is a school library consultant and children’s librarian in Sonoma County, California. She specializes in collection development and young adult literature. Her most recent publication with John Kornfeld, entitled “Comedy, Conflict, and Community: Home and Family in Harry Potter,” appears in Elizabeth Heilman’s Harry Potter’s World: Multidisciplinary Critical Perspectives. 相似文献
