学校的业务系统是在不同时期、不同背景、面对不同应用、不同开发人员等各种客观前提下建立的,其数据结构、存储平台、系统平台均存在很大的差异,所以学校各种源数据缺少统一的标准,数据难以转化为有用的信息,原始数据的不一致导致决策的可信度的降低.在此着重介绍了在数据仓库中数据转换服务(DTS)技术对不同数据源的数据进行转换,使得最终实现数据完整性和一致性. 相似文献

绘画中线条是点的运动轨迹,是一个可视的行动轨迹。线本身也不断的运动,表现不同的生命。没有线的前进、转向、曲缩和变化,就不可能有美的形式。线作为一种表现手段,是人类最初艺术才华的流露,也是人类几千年智慧的结晶,不同的画家,不同的思维方式,不同的文化积累,便会产生不同的绘画作品,可以说,线是艺术处理中表达感受最直接了当的语言,是人们认识和反映自然形态时最简明的表现形式。 相似文献

The present study explores pupils’ constructed definitions of the concept of function in relation to their abilities in dealing
with tasks of functions involving different forms of representations and problem solving tasks. A major concern is also to
examine the interrelations between these three ways of thinking about or dealing with the concept of function. The sample
of the study consisted of secondary school pupils in Cyprus. A test was developed which involved seven items: one item requested
pupils to provide a definition of what function is and the other six items were developed in order to investigate pupils’
ability to transfer information from one representation to another and to solve problems on function. Findings revealed pupils’
difficulties in giving a proper definition for the concept of function and resolving problems on functions involving conversions
between diverse modes of representation. Several inconsistencies among pupils’ constructed definitions, their competence to
use different representations of functions and their problem solving ability, were also uncovered, indicating lack of flexibility
between different ways of approaching functions. 相似文献

Abstract The idea that practical work in science is aimed at getting the right answer is strongly ingrained in practice and thinking, particularly those of students. While there are several different purposes for doing practical work, and hence several different kinds of practical work, the pressure to get the ‘right answer’ can affect what students, and teachers do. This paper looks at this issue and discusses two views of manipulation of data done by scientists/teachers, one of which is done for fraudulent purposes while the other is done for simplification. The paper also looks at the assumptions made by students and pressures which lead them to fudge their results. We suggest ways of dealing with these problems by looking inwards at the nature of the subject and trying to understand what constitutes good practice, and by looking outwards at the pressures, particularly those of examinations, which influence practice. 相似文献

One of the biggest problems teachers face is a lesson where the students are at different levels-some with quite competent English,some whose English isn't very good,and some whose English is only just getting started.Students from the same class are different from one another in many aspects such as aptitude,motivation,personality,and attitude.Teachers face this problem every day,so what are the possible ways of dealing with the situation.In this article,the author can suggest how can we teachers design classroom activities to cater for the students'individual differences. 相似文献

Drawing on data generated by a 3-year study, informed by ethnographic principles, of the interface between Gypsy culture and the educational system in the South West of England, this article focuses specifically on the experiences of young Gypsy males [1]. The manner in which they perform specific forms of masculine identity though business skills and dealing, fighting, and sex talk are considered. Tensions are highlighted regarding the ways in which these performances are valued in different communities of practice, and how this operates to maintain an atmosphere of suspicion regarding the educational system. 相似文献

语言与化密不可分,相互作用,英汉两民族的语言中都含有大量的有化意义的词,它们的化意义呈现出差异性,化意义部分相同;化意义截然相反;化意义只在一种语言中存在;化意义基本相同,研究英汉词汇的跨化差异有助于提高译的跨化差异的敏感性,正确理解和翻译原,对于英汉词汇的跨化差异的翻译,通常采用下列几种方法:音译法,直译法,替代法,增词法和意译法。 相似文献
