The Key Stage 3 Strategy is a complex and evolving government strategy intended to improve the education of 11‐ to 14‐year‐olds in England. This paper provides a snapshot of its development by early 2004, drawing on our evaluation of the pilot phase which began in 2000. The evolution of the Strategy, with its phased introduction of both subject and cross‐curricular strands, is described. We then examine the policy intentions and evidence base which underpin it before considering what the Strategy offers in terms of curricular and pedagogical reform. While the Strategy seeks to improve schooling for 11‐ to 14‐year‐olds, it has struggled to offer a coherent approach, though recent changes in emphasis may help. We conclude that a more radical approach to the learning needs of 11‐ to 14‐year‐olds is needed and draw evidence from international trends in middle years education. 相似文献

Developing a communal identity as beginning teachers of mathematics: Emergence of an online community of practice 总被引:1,自引:0,他引:1
The aim of this study is to investigate how a community of practice focused on becoming a teacher of secondary school mathematics
emerged during a pre-service teacher education programme and was sustained after students graduated and began their first
year of full-time teaching in schools. Bulletin board discussions of one pre-service cohort are analysed in terms of Wenger’s
(1998) three defining features of a community of practice: mutual engagement of participants, negotiation of a joint enterprise,
and development of a shared repertoire for creating meaning. Emergence of the online community was associated with our own
role in facilitating professional dialogue, the voluntary and unstructured nature of participation, initial face-to-face interaction
that created familiarity and trust, and the convenience of using email rather than logging on to a website. The study shows
that the emergent design of the community contributed to its sustainability in allowing the pre-service and beginning teachers
to define their own professional goals and values.

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

This is Part 2 of a two-part study of how APOS theory may be used to provide cognitive explanations of how students and mathematicians
might think about the concept of infinity. We discuss infinite processes, describe how the mental mechanisms of interiorization
and encapsulation can be used to conceive of an infinite process as a completed totality, explain the relationship between
infinite processes and the objects that may result from them, and apply our analyses to certain mathematical issues related
to infinity. 相似文献

With the flooding of pornographic information on the Internet, how to keep people away from that offensive information is becoming one of the most important research areas in network information security. Some applications which can block or filter such information are used. Approaches in those systems can be roughly classified into two kinds:metadata based and content based. With the development of distributed technologies, content based filtering technologies will play a more and more important role in filtering systems. Keyword matching is a content based method used widely in harmful text filtering. Experiments to evaluate the recall and precision of the method showed that the precision of the method is not satisfactory, though the recall of the method is rather high. According to the results, a new pornographic text filtering model based on reconfirming is put forward. Experiments showed that the model is practical, has less loss of recall than the single keyword matching method, and has higher precision. 相似文献

Theory Competition and the Process of Change 总被引:1,自引:0,他引:1
The reasons why many educational change initiatives have little impact are often framed in terms of either a poorly designed
process on the part of the change initiator, or in terms of problems with the attitudes, skills and/or knowledge of those
responsible for implementation. In this paper, we seek to integrate these two perspectives more closely by focusing on their
interface and the competing theories frequently held by the change initiators and implementers. This concept of theory competition
is illustrated with a case of a national literacy initiative in New Zealand in which the change initiators wished to raise
the achievement of low performing students through the development of “learning-centred” leadership in schools and evidence-based
practice. The desired outcomes were not achieved because theories about what it means to be a successful leader in such a
situation, the data needed to undertake the type of evidence-based analysis envisioned and school personnel beliefs about
the target students were understood differently by those responsible for initiating the change and those responsible for implementing
it. 相似文献
