不同逻辑背景对跆拳道运动员直觉思维效果的影响     

王长生 《北京体育大学学报》2009,32(1)

运动直觉思维是复杂运动情境中的主要运动思维形式,是运动思维能力的核心.但它的产生与所面临的问题情境和运动知识经验有关,与长期专业训练的逻辑思维指导有关.研究从跆拳道运动实践出发,以条件化的先验概率为逻辑思维背景材料,以决策为平台,探讨了不同逻辑背景对跆拳道运动员直觉思维准确性及决策速度的影响.结果表明:逻辑背景显著影响跆拳道运动员直觉思维决策效果.逻辑背景复杂性和运动直觉思维决策效果密切关联,简单的逻辑背景条件较复杂的逻辑背景条件下运动直觉思维准确性高,决策速度快.在不同逻辑背景下顶尖组具有直觉思维准确性的专家优势.  相似文献   

课堂环境下学生口语流利性难以形成的原因分析     

郎旭辉 《扬州教育学院学报》2010,28(2):73-76

口语流利性是口语表达能力中的重要组成部分,但大多数学生无法用英语进行自由交际。本文从教师的语言示范、课堂教学要求、母语影响和学生心理因素等方面,对课堂环境下学生口语流利性难以形成的原因进行分析。  相似文献

Quotation accuracy in educational research articles     

《Educational Research Review》2022

This study examined to what extent educational research articles are cited in accordance with content. Analysis of 500 randomly selected citations from articles published between 2016 and 2020 and listed in Web of Science Core Collection revealed an overall accuracy rate of 85%. Quotation accuracy was independent of a citation's specificity and bibliometric characteristics. However, the severity of quotation mistakes was associated with how specific the content of a referenced source is described and whether authors quote the work of a colleague or their own. These findings are discussed in light of established accuracy rates in other academic fields and measures to reduce quotation errors are proposed.  相似文献   

Automated monitoring of online news accuracy with change classification models     

《Information processing & management》2022,59(6):103105

In the past decade, news consumption has shifted from printed news media to online alternatives. Although these come with advantages, online news poses challenges as well. Notable here is the increased competition between online newspapers and other online news providers to attract readers. Hereby, speed is often favored over quality. As a consequence, the need for new tools to monitor online news accuracy has grown. In this work, a fundamentally new and automated procedure for the monitoring of online news accuracy is proposed. The approach relies on the fact that online news articles are often updated after initial publication, thereby also correcting errors. Automated observation of the changes being made to online articles and detection of the errors that are corrected may offer useful insights concerning news accuracy. The potential of the presented automated error correction detection model is illustrated by building supervised classification models for the detection of objective, subjective and linguistic errors in online news updates respectively. The models are built using a large news update data set being collected during two consecutive years for six different Flemish online newspapers. A subset of 21,129 changes is then annotated using a combination of automated and human annotation via an online annotation platform. Finally, manually crafted features and text embeddings obtained by four different language models (TF-IDF, word2vec, BERTje and SBERT) are fed to three supervised machine learning algorithms (logistic regression, support vector machines and decision trees) and performance of the obtained models is subsequently evaluated. Results indicate that small differences in performance exist between the different learning algorithms and language models. Using the best-performing models, $F_2$-scores of 0.45, 0.25 and 0.80 are obtained for the classification of objective, subjective and linguistic errors respectively.  相似文献   

微信互动时长对人格判断准确性的影响          下载免费PDF全文

陈少华林志鹏卢  桢 《宁波大学学报(教育科学版)》2022,(2):125-132

为研究微信即时互动情境中聊天时长对人格判断准确性的影响，笔者选取138名互不相识的大学生进行5min、10min和20min的微信聊天，对彼此的大五人格做出判断:（1）在所有互动组中，神经质的他评分数显著低于自评分数，而外倾性的他评分数显著高于自评分数；（2）总体而言，除神经质以外，大五人格其余四种特质的自我—他人一致性（SOA）均达到显著水平；（3）分组中，10min组的尽责性和外倾性，以及20min组的尽责性、宜人性和开放性的SOA都比较显著；（4）随着微信互动时长的增加，SOA呈上升趋势，但变化不显著。可见，更长时间的微信互动能使个体表露更多的个人信息，进行更深层的交流，因此观察者做出的人格判断也更准确，这对开展青少年心理健康教育无疑有重要意义。  相似文献
