金炳镐  肖锐  杨斯斐 《大理师专学报》2013,(2):1-9

正确认识中国特色社会主义民族理论,澄清干扰中国特色社会主义民族理论的观点,全面准确地宣传和运用中国特色社会主义民族理论,是坚持中国特色社会主义民族理论的三个重要问题。其中,正确认识中国特色社会主义民族理论是根本,澄清干扰中国特色社会主义民族理论的观点是关键,全面准确地宣传和运用中国特色社会主义民族理论是目的。本文对以上三个问题做出了理论阐述和理论回应。  相似文献   

论王维的赠答诗     

宫臻祥  刘曙初 《南京师范大学文学院学报》2013,(2):101-105

王维的赠答诗与特定的对象相应,具有正式场合的社交应酬、精神世界的沟通共鸣和诗歌领域的交流切磋三种不同性质。通过赠答诗的解读,我们可以看到王维作为官员、隐士、居士和诗人的不同身份,可以看到王维内心在身份选择和认同上的困扰。赠答诗反映了王维性格中动和静两种不同的倾向。  相似文献

学位论文摘要撰写偏差的案例分析——一种教育学视角     

牛拥 《教育与现代化》2013,(1):22-25,48

摘要是学位论文浓缩而精确的表达,是不加注释和评论但能反映论文同等量主要信息的短文。不过,由于研究生对学位论文摘要撰写的认识不到位等原因,当下学位论文摘要的撰写却存在着种种偏差,诸如“头重脚轻”式、“王婆卖瓜”式、“评判”式与“目录”式等,而矫正学位论文摘要撰写的偏差,则需要开门见山,直奔主题;客观陈述,杜绝抒情;过程展示,提纲挈领;问题先导,答案表达。  相似文献

建筑结构地震响应混沌特性及影响因素分析     

陈思坚  吴琛  杨超  郑志煌 《福建工程学院学报》2019,(1):36-42

采用混沌时间序列分析方法分别对以经典混沌信号和地震动为激励的结构响应进行混沌特性分析,从关联维数、Kolmogorov熵及最大Lyapunov指数等定量指标的角度,考察结构自振周期、地震动的类型和幅值等因素对结构地震响应的非线性特性的影响。研究结果表明:在经典混沌信号和地震动作用下,经过结构的放大和滤波作用,结构加速度响应仍然保留了混沌特性,且通过混沌参数的变化程度能够判断结构是否进入弹塑性状态。结构自振周期为结构加速度响应的混沌特性的主要影响因素;幅值对经典混沌信号作用结构下加速度响应的混沌特性影响较为显著;而地震动的类型、幅值等因素对地震动作用下响应的混沌特性影响更为显著。  相似文献

Reliably Assessing Growth with Longitudinal Diagnostic Classification Models     

Matthew J. Madison 《Educational Measurement》2019,38(2):68-78

Recent advances have enabled diagnostic classification models (DCMs) to accommodate longitudinal data. These longitudinal DCMs were developed to study how examinees change, or transition, between different attribute mastery statuses over time. This study examines using longitudinal DCMs as an approach to assessing growth and serves three purposes: (1) to define and evaluate two reliability measures to be used in the application of longitudinal DCMs; (2) through simulation, demonstrate that longitudinal DCM growth estimates have increased reliability compared to longitudinal item response theory models; and (3) through an empirical analysis, illustrate the practical and interpretive benefits of longitudinal DCMs. A discussion describes how longitudinal DCMs can be used as practical and reliable psychometric models when categorical and criterion‐referenced interpretations of growth are desired.  相似文献   

Automated Scoring of Constructed‐Response Science Items: Prospects and Obstacles     

Ou Lydia Liu  Chris Brew  John Blackmore  Libby Gerard  Jacquie Madhok  Marcia C. Linn 《Educational Measurement》2014,33(2):19-28

Content‐based automated scoring has been applied in a variety of science domains. However, many prior applications involved simplified scoring rubrics without considering rubrics representing multiple levels of understanding. This study tested a concept‐based scoring tool for content‐based scoring, c‐rater?, for four science items with rubrics aiming to differentiate among multiple levels of understanding. The items showed moderate to good agreement with human scores. The findings suggest that automated scoring has the potential to score constructed‐response items with complex scoring rubrics, but in its current design cannot replace human raters. This article discusses sources of disagreement and factors that could potentially improve the accuracy of concept‐based automated scoring.  相似文献   

An NCME Instructional Module on Polytomous Item Response Theory Models     

Randall David Penfield 《Educational Measurement》2014,33(1):36-48

A polytomous item is one for which the responses are scored according to three or more categories. Given the increasing use of polytomous items in assessment practices, item response theory (IRT) models specialized for polytomous items are becoming increasingly common. The purpose of this ITEMS module is to provide an accessible overview of polytomous IRT models. The module presents commonly encountered polytomous IRT models, describes their properties, and contrasts their defining principles and assumptions. After completing this module, the reader should have a sound understating of what a polytomous IRT model is, the manner in which the equations of the models are generated from the model's underlying step functions, how widely used polytomous IRT models differ with respect to their definitional properties, and how to interpret the parameters of polytomous IRT models.  相似文献
