教师的游戏观与儿童的自由——城乡学前教育比较中获得的启示

本研究采用以录像为媒介的集体访谈和多重话语分析的教育人类学研究方法,探讨了中国城乡幼教工作者对游戏,特别是对幼儿园中儿童自由游戏的不同看法.研究归纳出三种看似不同但实则存在内在关联和相互转化可能的游戏观.(1)儿童自由游戏只是幼儿园中游戏的一种,游戏化的教学活动也可以被称为游戏.(2)儿童自由游戏是真正的游戏,教学活动游戏化(或游戏活动教学化)固然有其合理性,但与游戏有质的区别.(3)高水平的自由游戏是儿童游戏的最高境界,"会玩"的儿童才能在游戏中享受到真正的自由.教师的游戏观影响了儿童对游戏、自由的体验.

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…

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.
