Does the Model of Language in the National Literacy Strategy Create Failure for Pupils from Differing Language Backgrounds?

The National Literacy Strategy (NLS) was introduced by the government in the wake of the hotly debated issue of falling educational standards in the UK. All schools were required to adopt the NLS Literacy Hour unless they could show their preferred programme would result in raised levels of achievement. My experience of delivering the Literacy Hour has been a process of adaptation to the needs of my pupils, who are drawn mainly from groups whose language backgrounds differ from that which is dominant in school. I have found that the requirements of NLS, together with many of the commercial resources used to teach it, are not appropriate for pupils from these groups and a question arose: is it the pupils who are in some way deficient or is it the approach and the resources being used? This article takes a case study of the use of a commercially produced resource to explore the model of language implicit in NLS, the kinds of resources it generates and the ways in which this creates failure in pupils from different language backgrounds. It then considers the New Literacy Studies and their implications for an alteration in our approach.

文本聚类分析结果可视化方法研究

针对文本聚类分析结果表达中缺乏语义关系的缺陷,本文利用人们在可视化形式下对模型和结构的理解和获取能力,提出了一种新的可视化表达方法。通过改进的Force-directed模型对聚类分析结果进行文本布局,表现文本间的语义相似关系;使用等值线生成算法构建层次性主题图,聚集和提炼文本主题;最终实现文本聚类分析结果的语义直观表达。实验结果表明,这种可视化方法不仅能够有效地表达聚类结果,体现类间、文本间的语义相关程度,而且还有助于发现隐含的信息,并通过类别之间的关联实现有效的信息导航。
