研究教育实践,教师的经验是一个不可回避的问题。本文将教师个体的教育经验想象为同心圃,分为三大层次:处于中心的是教育观念,中间层次是教育实践模式,最外层的是具体的教育事件。各层次紧密联系,形成一个系统,这是教师不断加工自己经验的结果。  相似文献

The term Tower of Babel has become synonymous with projects that have grand designs but end in confusion. So named in the Bible, the Tower is described in the Qur’an and in Judaic texts also, under different names. Its reputed purpose was to unify the nations of the earth with a common language. The Tower fell, however, and those who collaborated in its construction were scattered, their languages divided. The analogy has frequently been drawn between the Tower of Babel and the Internet. This reflection considers whether this analogy is justified within the context of contemporary distance education.  相似文献

在由实词与实词组成的句法结构中,总是同时并存着两种结构关系:语法结构关系和语义结构关系。这是两种性质完全不同的结构,二者之间存在着错综复杂的关系,主要表现在:同一种语法结构可以表达多种语义结构;多种语法结构可以表达一种语义结构;同一种语法成分,可以有不同的语义指向;同一个句子,可以表现出不同的语法结构和语义结构。  相似文献

Reform in science and mathematics curricula has moved from rote learning of facts and computation skills toward learning a structure of a subject matter. While the reasons for this shift, such as greater understanding, transfer and intellectual excitement are admirable, there is little empirical evidence to support them. A first step in examining such claims is to develop methodology for representing structure in the to‐be‐learned instructional material and in students' memories. The purposes of this paper, then, are to present (a) a method for examining a subject‐matter structure in prose materials, (b) methods for examining a subject‐matter structure in students’ memories, and (c) data bearing on the validity of structural interpretations of these measures. If these structures can be represented objectively and independently — even if not in a complete form or error free — a beginning has been made in validating the reasons for teaching structure.  相似文献

人们在注重轿车造型的同时,却忽视了货车造型,而高速公路上的货车流量与轿车不相上下,货车笨拙的造型,破坏了高速公路上车流的整体美感。研究货车的车身设计、外观形状、座舱内饰,对于降低货车的运营成本、提高货车的品味、美化我们的生活、让货车的驾驶室先进新潮,更具人性化等方面具有重要意义。  相似文献

In this study the authors start from the observed fact that equality of opportunities of educational achievement is higher in integrated school systems than in differentiated school systems. In other words, in integrated school systems, a pupil’s school achievement depends less than elsewhere on the social and cultural resources of his or her family. However, before concluding that school structure has a significant influence on inequalities at school, it is important to distinguish between the influence of the socio‐economic context underlying each school system, and the specific influence of the structure or organisation of the school system itself. The fact is that not only do the most egalitarian countries with regard to schooling have in common an integrated structure, but also these schools are set within the context of countries which are more egalitarian in other ways, particularly with regard to income distribution. To distinguish between the influence of this social environment and that of school structure, the authors offer three analyses based on a comparative analysis of international databases measuring educational achievement. The results of these three analyses lend credence to the hypothesis that the structure of the school system has a specific effect on the extent of inequalities.  相似文献
