对一位大班数学学习困难儿童的个案研究——重点考察幼儿园和家庭环境中的负面因素

目前关于数学学习困难儿童的研究大多关注其行为表现和认知特征,较少涉及其生活环境中的负面因素。本研究以一名大班数学学习困难儿童为研究对象,通过对儿童本人及老师、父母和同伴的访谈以及对儿童日常活动的观察,对其生活环境中的负面因素进行分析,为认识早期数学学习困难儿童的发生、形成和持续的原因提供了一个生态视角。研究结果表明,数学学习困难儿童在师幼交互、同伴友谊、家庭环境、父母教育方法、亲子关系等诸多方面有负面经历,而这些经历直接或间接地影响了儿童的数学学习。     

Nearest neighbor search algorithm based on multiple background grids for fluid simulation

The core of smoothed particle hydrodynamics (SPH) is the nearest neighbor search subroutine. In this paper, a nearest neighbor search algorithm which is based on multiple background grids and support variable smooth length is introduced. Through tested on lid driven cavity flow, it is clear that this method can provide high accuracy. Analysis and experiments have been made on its parallelism, and the results show that this method has better parallelism and with adding processors its accuracy become higher, thus it achieves that efficiency grows in pace with accuracy.     

Unexpected changes of itinerary – adaptive functioning difficulties in daily transitions for adults with autism spectrum disorder

Adaptive functioning skills, also known as adaptive behaviours, refer to a multifaceted concept defined as behaviours necessary for age-appropriate, independent functioning in social, communication, daily living or motor areas. In light of the growing population of children with ASD who will eventually become adults, increased understanding of adaptive functioning during the transition to adulthood is of importance, but current research in this area lacks first-hand evidence presenting adaptive skills difficulties among older adolescents and adults with ASD. This article focuses on adaptive functioning skills in daily transitions for adults with Asperger’s syndrome (AS) or high-functioning autism (HFA). It draws on evidence from 12 interviews with individuals on the autism spectrum age 16–43, and 2 focus groups with 8 family members of people affected by ASD. Particular emphasis is placed on impact of adaptive functioning difficulties on well-being and quality of life for adults with ASD. Grounded theory approach has been used to analyse the gathered data. Interviewees reflected on daily challenges associated with unexpected changes in routine, sensory difficulties and social interactions. These in turn had an impact on their adaptive functioning skills by introducing complications in the process of making transitions between different contexts and decreasing interviewees’ ability to tackle challenges of daily life. Importance placed on societal expectations towards meeting bespoken standards and conforming to norms ruling the structure and interactions of daily life were also widely discussed. Frequently such expectations did not allow for factoring in the developmental nature of ASD and related difficulties, which as a result triggered additional complexity in managing daily transitions for adults on the spectrum. Further research addressing adaptive functioning skills in daily transitions for adults with ASD is needed.     

权力多极化的课程权力定位——超越中央与地方的思维框架

在已有课程权力定位的基础上，克服集权与分权的困境，建立以市场经济为背景、市民社会理论所阐述的权力多极化的课程权力定位。其以分权为基础、以细分课程权力为手段，各种权力由相应的权力主体行使而不是笼统地提集权、分权或共有的课程权力分配体制，其核心是向社会分权。     

在职教师网上学习困难之调查报告

网上学习为在职教师提供了一种灵活的进修机会,促进了教师终身学习的发展。然而,通过几年的实践,学员们在这一新的学习模式下会产生哪些困难呢?本研究以华东师范大学网络教育学院在职进修教师为样本,采用网上问卷调查的方法,旨在探讨在职教师网上学习的主要困难及影响因素。本研究收回的有效问卷为196份。研究发现,教师网上学习的困难包括基础设施条件、操作技能、资源,以及个人等方面,影响网上学习主要因素包括网上教师水平、网上学习环境、网上学习支持等等。根据在职教师网上学习困难的综合分析,作者提出了一系列改进网络教学的策略性建议,可供网上教学工作者参考。

基于无线通信的静止式进相器系统设计

静止式进相器是专为大中型绕线式电机节能降耗设计的无功功率就地补偿装置。现有静止式进相器仅停留在单台电动机和单台静止式进相器的配套使用上,缺乏监控系统、历史数据无法保存。详细介绍了基于无线通信的静止式进相器系统设计,系统由静止式进相器控制子系统和主控子系统组成,使用无线通信模块实现静止式进相器和主控机的通信。主控子系统设计中,采用预约ALOHA实现主控子系统的多址通信。该系统经过实验和现场调试,其结果表明:静止式进相器补偿效果明显,实现系统无线通信功能,满足无线监测的设计要求。

论多元族群共生的中国儿童文学

中国各民族共同创建了悠久、灿烂的中国儿童文学。中国各民族原生活态儿童文学曾经代表着中国儿童文学的存在,自远古起就活跃于歌者、说者的通神语境和巫师的祝告祷告行为之中,以口口相传的方式在各民族儿童中代代传承。梳理多元族群共生的中国原生活态儿童文学,是建立中国本土儿童文学史新观念的一个起点。     

高校思想政治教育困境及调试对策：基于审美的思考

从审美角度看,高校思想政治教育出现困境的原因表现为：思想政治教育内容的重复性、教学方法的单一性及教育的＂病理性说服＂导致大学生审美疲劳,社会转型期审美文化错层导致大学生在思想政治教育过程中产生＂审美饥饿＂,以工具理性为指导的思想政治教育功能论和价值论导致教育过程审美的单向度。要摆脱高校思想政治教育困境,应创新教育方式方法,创设教学情境,重塑审美形象;立足传统审美文化,合理利用大众文化,构建和谐的当代审美文化;改变教学理念,加强教育过程中的审美互动。
