国外基于任务的信息交互研究现状与进展     

韩正彪  翟冉冉 《情报资料工作》2022,(1):81-91

[目的/意义]本文旨在对国外基于任务的信息交互(Task-Based Information Interaction, TBII)的研究成果进行系统的综述,并以此为基础构建TBII的集成化研究框架。本研究有利于为今后探索TBII的研究提供理论基础。[方法/过程]基于文献调研的方法,对国外基于任务的信息交互研究的现状与进展进行了归纳总结。[结果/结论]研究发现国外学者对于该主题的研究涉及TBII基本概念、TBII阶段的划分、TBII子活动的影响因素和TBII活动完成的影响因素四个主题。研究构建的TBII集成化研究框架将以上四个主题按照一定的逻辑关系进行整合。该框架的功能如下:第一,可以揭示TBII各活动阶段的交互关系;第二,可以识别出用户、任务、TBII活动阶段、信息系统及任务产出、效果、绩效之间的关系机理;第三,提出了TBII研究的四种基本研究路径。  相似文献

How repeated studying and testing affects multimedia learning: Evidence for adaptation to task demands     

《Learning and Instruction》2016

Two biases can occur in multimedia learning: overconfidence and over-reliance on text processing. The present research sought to identify these biases and to investigate whether they can be reduced, and hence learning fostered, when studying and testing are repeated. In 2 experiments (Exp.1: N = 79, Exp.2: N = 52), students learned either with text only or with text and pictures (multimedia) about how the toilet flush works, gave judgments-of-learning (JOLs), were tested on the learning contents; afterwards this study-test cycle was repeated. Results from both experiments revealed stronger overconfidence due to multimedia in both study-test cycles (JOLs higher than learning outcomes). Eye movement data showed a relative increase in attention on the picture versus text from cycle 1 to cycle 2; this relative increase in attention was related to better learning outcomes. Repeated studying and testing thus helped to reduce over-reliance on text processing in multimedia learning, fostering performance.  相似文献   

不同母语背景留学生汉语阅读中字音、字形作用的特点   总被引：1，自引：0，他引：1  

张金桥 《华南师范大学学报(社会科学版)》2007,(2):119-123

采用校正任务探讨了母语为拼音文字和表意文字的外国留学生在汉语阅读中字音、字形作用的特点。结果表明，初级汉语水平的拼音文字背景留学生字音发挥主要作用，中级汉语水平的拼音文字背景留学生字音、字形起相同重要作用；无论是初级汉语水平还是中级汉语水平的表意文字背景留学生，都是字形发挥主要作用。本研究结果初步表明，初级汉语水平留学生主要受其母语认知加工特点的影响，中级汉语水平留学生受到母语和目的语认知加工特点两个方面的影响。  相似文献

Timescales for exploratory tactical behaviour in football small-sided games

The aim of this study was to identify the dynamics of tactical behaviour emerging on different timescales in football small-sided games and to quantify short- and long-term exploratory behaviour according to the number of opponents. Two teams of four professional male footballers played small-sided games against two different teams with a variable number of opponents (3, 5 and 7). Data were collected using a combination of systematic observation and a non-differential global positioning system (15 Hz). The temporal diversity and structural flexibility of the players were determined by calculating the dynamic overlap order parameter q, entropy and trapping strength. Analysis of the exploratory dynamics revealed two different timescales, forming a different metastable landscape of action for each constraint. Fast dynamics lasted on average a few seconds and consisted of changes in tactical patterns. The long timescale corresponded to the shared tasks of offence and defence lasting tens of seconds. The players’ tactical diversity decreased with an increasing number of opponents, especially in defence. Manipulating numerical imbalance is likely to promote changes in the diversity, unpredictability and flexibility of tactical solutions. The fact that the temporally nested structure of constraints shaped the emergence of tactical behaviour provides a new rationale for practice task design. The manipulation of numerical imbalance on the timescale of a few tens of seconds, on which the exploratory behaviour of players saturates, may help coaches to optimise the exploratory efficiency of the small-sided games.  相似文献

构建高职教育专业培养目标体系     

胡永信 《张家口职业技术学院学报》2006,19(2):1-4

高职教育应根据对职业岗位工作分析和任务分析确定其专业培养目标。把完成任务的最终绩效目标作为业务目标，按学期分段构建具有高职特色的专业培养目标体系。这样有利于发挥专业培养目标对课程设置、教学内容组织、教学方法选择的指导作用，同时使教学质量监控与评价有了科学的客观的依据。  相似文献
