Temporal relation computation is one of the tasks of the extraction of temporal arguments from event,and it is also the ultimate goal of temporal information processing.However,temporal relation computation based on machine learning requires a lot of hand-marked work,and exploring more features from discourse.A method of two-stage machine learning based on temporal relation computation(TSMLTRC)is proposed in this paper for the shortcomings of current temporal relation computation between two events.The firs... 相似文献

时间基准是确定一个时间词语所指时间的量度或在时间流中的位置的基本标准。时间基准按性质可以分为天象基准、人为基准、经验基准、事件基准和当前基准;按关系可以分为共点基准和互为基准。每个时间词语都有基准,理解基准是理解时间词语意义的关键,“上(下)、前(后)”与T组合而成的时间词语之间的种种意义和用法的不同可以从基准角度得到科学的解释。 相似文献

话语分析-研究CSCL中协作意义建构的新方法 总被引：1，自引：1，他引：0
计算机支持的协作学习(CSCL)中学习者主要是通过对话来进行意义建构的,意义体现在话语之中。因此话语成为研发和分析协作意义建构的焦点。在过去的二十年中,研究话语正在成为研究社会情境下学习的一个重要的理论视角,因此通过研究话语来研究网络教育成为该领域的一个新的研究路径。文章在探讨了话语的概念和特点的基础上,阐述了话语分析的发展历程和理论基础。结合CSCL中协作意义建构的特点,提出了适合运用话语分析方法研究问题的要素、原则和方法,最后提出了运用话语分析可以研究的CSCL问题及其意义。 相似文献

The characteristics of acoustic emission(AE)signals given off in the course of the failure of a concrete structure is explored based on the laboratory experiments with concrete specimens.It is observed that the failure of a concrete structure experiences three stages divided by two inflexion points on the AE event curve,which are sequentially no damage,damage initiation and propagation,and major failure stages.In the first stage,existing micro cracks and defects are compacted by loading. but no damage propagated,hence few AE signals are detected,and it appears that there exists a nearly linear relationship between the relative stress and relative strain.In the second stage,the AE event frequency increases implying that micro cracks begin to emerge inside the concrete structure,which is consistent with the damage mechanics.When the load is over 80% of that breaks the structure,i.e.the maximum load,there is a vertical jump on the AE event count curve,which suggests that the failure propagation speeds up.After the second inflexion point,the AE event density increases faster than before,and there is another jump just before breaking,which indicates a quick propagation stage.These findings are valuable for evaluating the damage situations,and for studying and monitoring the dynamic process of the failure behaviors of a concrete structure. 相似文献

The goal of this study is to examine the comprehension of global causal and temporal relations between events that are represented
in single hypertext documents. In two experiments we examined how reading sequences of hypertext nodes affects the establishment
of event relations and how this process can be supported by advanced organizers that provide either temporal or causal pre-information.
In the first experiment we could show that discourse structure affected recall of temporal event sequences only when causal
relations were absent. In a second experiment, the comprehension of either temporal or causal relations was facilitated by
providing different types of pre-information (advanced organizer). Temporal pre-information facilitated recall of temporal
event sequences without underlying causal relations. In contrast, causal pre-information facilitated recall of temporal event
sequences with causal relations. The results demonstrate that readers use causal information to construct temporal event sequences. 相似文献

职业教育课程的学科话语与实践话语 总被引：10，自引：0，他引：10

20世纪90年代以来,我国职业教育课程的学科话语与实践话语的争论经历了从“数量”到“逻辑”两个阶段。尽管在学术领域实践话语占据了主导,在实践领域却是学科话语占据着主体。目前,我国职业教育课程正处于从传统的以学科课程为主体的课程模式,转向以项目课程或任务引领型课程为主体的课程模式阶段。职业教育课程从学科话语到实践话语的转换,实际上意味着思考课程问题的思维方式的转换。职业教育课程设计应当充分考虑学生的学习特点,打破从理论到实践的机械课程设计思路,转向让学生在工作实践的基础上,通过自我反思来建构理论知识。 相似文献

库切的作品中充满了对主奴关系的哲学反思,在南非文化语境下,这种反思主要指向殖民者的自我和殖民地的他者之间的关系。库切通过细致地展示殖民者不断地对自我进行复制和对他者进行想象的过程,通过剖析殖民者居高临下的单向透视角度对他者主体性的变形和殖民者的自我与他者存在不可分离的关系,揭示出殖民者的自我和殖民地的他者双方的特征都是出自权力的操作和话语的建构,矛头直指殖民话语背后的哲学基础。 相似文献

小句关系理论是20世纪60年代末E.Winter最早提出的关于语篇分析研究的一个重要理论,该理论强调了小句之间的逻辑语义关系。在英语写作教学中教师可以借助小句关系理论,从英汉语篇对比的角度,强调中西方语言结构差异,强化学生英语思维模式。 相似文献

This paper reports findings of a pilot study that examined the pedagogical potential of Second Life (SL), a popular three‐dimensional multi‐user virtual environment (3‐D MUVE) developed by the Linden Lab. The study is part of a 1‐year research and development project titled ‘Modelling of Secondlife Environments’ ( http://www.le.ac.uk/moose ) funded by the UK Joint Information Systems Committee. The research question addressed in this paper is: how can learning activities that facilitate social presence and foster socialisation among distance learners for collaborative learning be developed in SL, a 3‐D MUVE? The study was carried out at the University of Leicester (UoL) within an undergraduate module on Archaeological Theory, where two tutors and four students took part in four learning activities designed to take place in SL within the UoL Media Zoo island. The learning activities and training in SL were based on Salmon's five‐stage model of online learning. Students’ engagement in SL was studied through interviews, observations and records of chat logs. The data analysis offers four key findings in relation to the nature and pattern of in‐world ‘socialisation’ and its impact on real‐world network building; the pattern of in‐world ‘socialisation’ stage in Salmon's 5‐stage model; perspectives on students’ progress in‐world through the first stage of the model—‘access and motivation’—and perspectives on their entry into, and progress through, the second stage of the model—‘socialisation’—and the role of identity presented through avatars in the process of socialisation. The paper offers implications for research and practice in the light of these findings. 相似文献

This chapter is a based on a study that examined, first, Finnish comprehensive school pupils’ transfer to secondary school and, second, the ways in which pupils’ experiences of schooling can contribute to the development and planning of an undivided comprehensive school system. Traditionally, Finnish discourse on the flexibility of the transfer has concentrated on the teacher's role as the central transformative force in bridging the gap between primary and secondary school. The voice of the pupils, who experience the changes, has tended to be regarded as of minor importance. When moving towards a fuller understanding of the transfer experience, it is important not only to include the pupils’ perspective but to examine, first, the school community and the factors promoting and/or preventing its functioning and, second, the learning environment of the adolescent. The results of the study clearly show that the pupils are able to assess the qualities of their school as a learning environment and to cope with the changes that result from the transfer to secondary school. Pupils were also ready to participate in developing a more unified comprehensive school system, but expressed their school experiences in a manner reflecting their developmental stage of adolescence and the prevailing school cultures. Thus, it remains the professional task of the teacher to analyse and interpret these messages in order to identify the key ingredients needed for developing such a system. 相似文献

The main purpose of this paper is to explore the perception of applying self-and peer-assessment in English writing,through an Action research process.The learning in the programme,the students have learnt translating Chinese into written English for first stage,and have learnt writing in English for second and third stage through self-and peer-assessment.The research result shows that the most students feel that the process of self-and peer-assessment are useful for improving their English writing skill and they feel that self-reflection and peer discussion around their English writing is helpful for promoting the development of self-and peer-assessment.Especially,key findings about four types of students are more important.Overall,based on student’s perception about using self-and peer-assessment,learning written in English is also an ongoing research,it can develop the ability of students’ ability to solve problems independently,and raise their language communicative competence gradually. 相似文献

解读课程理论与教育学的关系--兼论当前课程研究方向的转型 总被引：2，自引：0，他引：2

课程研究的兴起使课程理论成为教育理论中的显学，课程理论在试图涵盖教学论的同时，也进入了教育学尤其是教育学基本理论的领域，造成了后者的危机。但双方是一种在相互汲取中成长的关系，而不是此消彼长，甚至以一方取代另一方的关系。为此，应重视二者相互之间的价值。当前，中国课程理论研究中的“问题”，首先是实践问题，然后才是学术问题，实践关怀成为课程研究者的主导性意识。不应盲目跨越“课程开发”阶段，而要慎重对待“课程理解”研究范式的转型。 相似文献
