The effects of morphological structure on reading proficiency—A developmental study

The present report with three inter-related studies examined the effects of morphological complexity on reading proficiency in 103 fourth graders, 88 fifth graders and 107 sixth graders trichotomized into below average, average and above average readers. The reaction time paradigm and the developmental framework with three age groups provided more sensitive and stable results for inferring mental processes in accessing the lexicon. Study 1 on lexical decision with visually presented words and non-words with different morphemic boundaries suggests that words can be accessed in a decomposed state as morphemes by children. Study 2 and the complementary Study 3 requiring the vocalization of derived or base forms of words primed by target items in sentence frames indicate that words might be accessed in full forms. Further, the depth of derivational morphology and of base morphology with correlated phonological changes affect reading proficiency.     

教学文化研究引论

教师群体共享的思维方式、信仰和价值观念构成的教师职业文化对于教师教学行为和观念的转变具有重要影响.由于对教学文化的特征缺少关注,致使目前的教师专业发展陷入低效,自上而下的教育变革也在一定程度上受到阻抗.探明教学文化的存在状态和特征对于教育改革的推进和教师的专业发展以及学校管理的变革都具有极其重大的意义.然而,文化的存在具有特殊性,作为一种符号形式的社会建构、理解和运用,作为社会事件中的意义与价值的象征系统,它的研究只能采取一种探索意义的阐释性科学的方法.教学文化研究既要关注宏观的世界文明类型影响下的教学文化类型和微观的学校教育环境影响下的教学文化构成与特征,还要在教学文化的影响因素与发展机制的研究的基础上,顺应教育回归生活的历史趋势,寻求教师职能与观念的转变的必然取向.     

The use of microcomputer technology in a modular approach to reading and reading difficulties

This paper outlines the theoretical framework of a two-year two cohort study of inter-related modules to model reading in 300 grades 4, 5 and 6 readers, and describes the specially designed microcomputer programs written in Turbo Pascal to implement this modular approach. In brief, the modular approach postulates the interrelated phonological, morphological modules in processing words and sentence/paragraph processing. These three modules or components are subserved by 10 measurable tasks all implemented on the microcomputer (IBM-PC compatible) with reaction time measures as indices of the different facets of verbal efficiency. Statistical analyses of the large data sets for Phase 1 show the linear structural equation modelling fits the data reasonably well. In particular, the morphology task consistently explains between 32% to 44% of the variance in reading performance in the three grades. The findings lend themselves to specific approaches to habilitation in the different components or sub-components.This study was supported by a grant (No. 410-86-0048) from the Social Sciences and Humanities Research Council of Canada awarded to Che Kan Leong. Simon Lock and Jacky Lau were responsible for the microcompurter programming. Edward Danskin, Melvin Kelley, Donald Simmons, Louise Sellinger, Kristin Strauss and Tara Wiley carried out the experimentation with individual children in the schools. The cooperation of the principals, the teachers and the subjects was greatly appreciated. Requests for reprints should be addressed to Dr. C. K. Leong, Department for the Education of Exceptional children, University of Saskatchewan, Saskatoon, Canada, S7N OWO.     

Study on dynamic response of embedded long span corrugated steel culverts using scaled model shaking table tests and numerical analyses

INTRODUCTION On Jan. 17, 1995, the Hyogoken-nanbu earth-quake in Kobe, Japan, caused great destructive and damage to underground structures, such as subway structures, mountain tunnels, multipurpose under-ground ducts and other underground structures, which had previously been considered to be resistant to earthquake effects (JSCE, 1996; ECRHAED, 1998). This earthquake revealed that a number of critical issues should be added in the seismic design and seismic strengthening of undergr…

党风廉政建设视域下举报人安全机制的构建

举报对加强党风廉政建设具有非常重要的作用。然而,现在的举报制度和保护措施不健全,造成举报人屡受伤害,扼杀了举报的积极性。鉴于此,国家应该加强机制建设,制定专门的法律保护举报人,实行泄露举报人信息问责制,建立中央直管的举报信息系统,完善举报人救助制度,发挥媒体的舆论引导作用,让举报成为人民监督的重要手段。     

基于XML的公交查询系统设计

XML技术作为一门新兴技术,在许多领域都得到了广泛的支持并有着广阔的应用前景。作为数据表示的一个开放标准,XML语言给Web应用乃至网络计算注入了新的活力,其与HTML、SGML以及关系数据库之间的关系也是值得探讨的。本文通过＂基于XML的公交查询系统设计＂这样一个实例的制作来具体详细地阐述XML在Web上的广泛具体的应用。
