浅谈小学语文阅读教学中的情感教育

情感是小学语文教育的灵魂,它既是学习语文的手段,又是小学语文教学的目的.情感教育指的是在教学过程中用美文灌之以情,教师动之以情,学生会之以情,由无数的"情"的操作而综合为"情操"的生成,达到心灵和心灵的契合的一种教育方式.而语文作为一门主干课程,与其他课程相比,更强调情感.现行的小学语文教材大多是名家名篇,题材广泛、文质兼美、图文并茂,字里行间蕴涵着作者丰富的情感和审美情趣.     

认知视角下的习语可分析性与习语教学

传统习语观极大制约着习语研究和习语教学。认知语言学理论为习语的研究与理解提供了理论基础和认知框架,同时也为习语教学提供了新的视角。借助隐喻、转喻和常规知识等认知机制能够对大多数习语意义进行分析;在教学中,应关注习语并注重对习语认知分析的课堂输入和适当教学策略的配合,使学习者意识到汉、英习语在概念体系和文化内涵上的异同,从而培养和提高其准确运用习语的能力。     

综合性文献数据库用户心智模型理论问题初探

首先,从多个学科视角对心智模型的概念进行分析。其次,分析心智模型引入到情报学信息行为研究领域的原因,并对心智模型与信息行为研究的一些核心范式间的关系进行探索,从而确立在信息行为情境下分析用户心智模型的理论基础。最后,对我国综合性文献数据库用户心智模型的形成和构成进行分析,以为今后从定量化角度测量心智模型提供理论支持。     

基于CSSCI本体的知识服务模式研究

为充分发挥知识在组织科学决策中的作用,将本体机制引入信息服务领域以实现知识服务的解决方案,对基于本体知识应用的三个方向,包括知识地图、知识检索和知识创新等进行总结。在此基础上,以CSSCI知识服务为例,在假设CSSCI知识本体已经构建完成的情况下,提出并论证基于CSSCI本体的知识服务模式,即知识检索服务和科学评价服务,以提高CSSCI的服务质量。     

研究脉络梳理方法的计量分析

通过研读与"研究脉络"密切相关的中文核心期刊学术论文,从研究对象、梳理思路、定量指标以及分析方法等方面进行考察,设计具有三个层次的41项特征指标,并逐篇进行特征提取及汇总统计分析。在此基础上,归纳总结出研究脉络梳理的主要内容及其定量分析方法与指标,并提出主要工作步骤,以期研究出一套全面、客观的研究脉络梳理方法。     

A demographic and epistemological divide: problematizing diversity and equity education in traditional,rural teacher education

This study documents the experience of an Asian woman faculty in the rural Mountain West as it relates to difficulties teaching predominantly White preservice teachers about the importance of diversity and social justice to prepare them adequately with skills and materials for their P-12 classrooms in a rapidly changing world. The current challenge has its origins in US history (the macro-level) and continues into the present (the micro-level) beyond the preservice teachers to include college of education colleagues and administrators, and community members. Using nexus analysis to reveal this larger picture, the hope is to develop actions to keep the problem from persisting into the future. This study is geography-specific in that not all rural areas are predominantly White, nor do they all share the same worldview. The results suggest that rural university communities remain predominantly White in their demographic makeup and crucial actors often hold fast to Whiteness and White ignorance. This is problematic – the need to transform and change is urgent in rural teacher education programs.     

Composite fault-tolerant control with disturbance observer for stochastic systems with multiple disturbances

In this paper, a composite fault tolerant control (CFTC) with disturbance observer scheme is considered for a class of stochastic systems with faults and multiple disturbances. The disturbances are divided into two parts. One represents the stochastic disturbance with partial known information which is formulated by an exogenous system. The other is independent Wiener process. A stochastic disturbance observer is designed to estimate exogenous disturbance. To make the first type of disturbance can be rejected and the fault can be diagnosed, a composite fault diagnosis observer with disturbance observer is constructed. Furthermore, a composite fault-tolerant controller is proposed to compensate disturbances and faults. Finally, simulation examples are given to demonstrate the feasibility and effectiveness of the proposed scheme.
