ABSTRACT

Small primary schools have often been criticized for their staff's inevitably limited cur‐ ricular expertise and consequent difficulty in providing a full National Curriculum for their pupils. Yet in terms of standards of attainment and quality of teaching such schools are rated rather more favourably than larger ones in OFSTED inspections. Based on an investigation of policy and practice in thirteen small primary schools this article attempts to examine the reality of small schools’ planning and implementation of National Curriculum requirements at Key Stage 2 and suggests possible reasons for their ‘better’ performance, at least as judged by OFSTED inspectors.  相似文献

Abstract

This article describes the way the Internet has been introduced to a small community in South Australia, by means of a business system originally provided for the Council's use. Internet, while heard about, had never been used to any great extent, and is a good example of introducing the ‘young’ of our subject to this facility ‐‐ those young being council workers and the general public.  相似文献

The rationality of students’ alternative frameworks is discussed by considering the role played by their beliefs, their understanding of other views and the reasons they give to justify their own beliefs and to reject alternatives. These notions are used in an investigation of some of the cognitive effects of a series of introductory lessons about electricity on a class of 14‐year old boys. Changes which occurred not only in the beliefs of the students but also in the mental context in which these beliefs were embedded, were studied. Some of the implications of the findings for teaching science are briefly discussed.  相似文献

The first full biography of Ursula Moray Williams has been published to mark the centenary of her birth. In this article, its author, Colin Davison, assesses her work in the context of her life, paying particular attention to the way that her extraordinary childhood influenced her writing. He also examines new evidence about where her ideas came from for some of her best-known works.  相似文献

ABSTRACT

Cyclists in the Tour de France are endurance specialists. Twin and family studies have shown that approximately 50% of the variance in a number of performance-related phenotypes (whether measured at baseline, i.e., natural talent, or in response to training) including those important to cycling can be explained by genetic variation. Research into the specific genetic variants that are responsible has identified over 200 genes containing common genetic variants involved in the genetic predisposition to physical performance. However, typically these explain only a small portion of the variance, perhaps 1–2% and collectively they rarely explain anything approaching the 50% of the variance identified in the twin and family studies. Thus, there is a gap in our understanding of the relationship between heritability and performance. This gap may be bridged by investigation of rare variants or epigenetic variation or by altering study designs through increased collaborations to pool existing cohorts together. Initial findings from such efforts show promising results. This mini-review will touch on the genetics and epigenetics of sporting performance, how they relate to cyclists in the Tour de France and where best future efforts may be directed as well as discuss some preliminary research findings.  相似文献
