“再说”的语法化历程

"再说"最初是一个结构,后来词化为一个词。一般的词典上列"再说"为两个义项,但实际上"留待以后处理"义的"再说"有动词和助词两种词性,应该看做不同的义项。主要考察包括结构在内的"再说"的四个意义的关系和演变过程,借助认知理论、去范畴化理论、语法化理论等,试图明晰"再说"的发展脉络、再现其语法化历程。

发挥学生在高中英语教学中的主体作用的策略探讨

学生在高中英语教学中的主体作用直接影响着课堂教学效果。教师可以从分层教学、开展合作性学习和课堂活动、充分利用多媒体、训练学生思维发展等方面体现和发挥学生的主体作用。     

基于最值中滤波的彩色图像噪声滤波器

构建了一种新的消除彩色图象中脉冲噪声的滤波法。该滤波首先根据极值点(最大或最小)的判别标准将全部像素分为两类(信号S与噪声N),再根据空间相关性将噪声点用该点邻域的中值取代,然后进行简单的局部纹理分析而自动选择使用标量中值滤波或者使用矢量中值滤波。实验表明,文中提出的方法计算量少,性能优良,图象信噪比高。     

网络多媒体在游泳教学中的运用

Utilization of online educational resources in teaching: A moderated mediation perspective

The study builds on a newly modified Technology Acceptance Model (TAM) to substantiate the motivation and operation of teachers’ utilization of online learning resources. A ‘Comprehensiveness’ construct is proposed in the modified TAM to reflect the breadth and depth of rich online knowledge. This new construct serves as the mediator between ‘Usefulness’ and ‘Behavioral Intention’ in the new TAM structure. In addition, the ‘Ease of Use’ factor in conventional TAM is proposed to moderate the mediation in the modified TAM. Survey data are collected from 301 teachers undertaking certified training in Macau and Structural Equation Model (SEM) technique is used to assess the model. Moderated mediation is evaluated using both multi-group bootstrapping method and moderated path analysis method. Both methods verify the presence of moderated mediation with partial mediation in high Ease of Use values and full mediation in low Ease of Use values. Theoretical implication of the current study extends the coverage of TAM applications and academic implication suggests the strengthening in teachers’ professional development and government sponsorship in building repositories of online resources.     

The Perfect Marriage? – Language and Art Criticism in the Hong Kong Public Examination Context

Art education in Hong Kong has undergone various changes in response to educational reform. In art assessment, a major change in the Hong Kong New Senior Secondary (NSS) Curriculum is the inclusion of art criticism as a compulsory component of the new public examination. Assessing students’ abilities to interpret art in an art criticism public examination context is a critical issue in Hong Kong because the new senior secondary curriculum and assessment has brought attention to the role of written language in the art examination paper. This means the examination assesses not only students’ abilities to interpret art, but also their language abilities required to respond to art in written form. Since this new mode of assessment of art criticism has been published a number of issues have appeared. Recent studies show that teachers and students perceive this development negatively and they believe that the written format will assess students’ written language abilities rather than their critical abilities. These findings challenge the justification of the new art assessment policy and raise questions about the role of written language in responding to art. This article aims to raise the issue of the marriage between language and art criticism in the Hong Kong public examination context. It argues and examines the relationship of language to art interpretation, reasoning in the assessment, and issues in the public art criticism examination context. The issues addressed in this article provide opportunities for researchers and policy makers to reconsider and refine the new form of examination.

知识问答社区用户心流体验对持续知识共享意愿的影响研究——以PAT模型为视角

[目的/意义]为解释知识问答社区用户分享知识时的情绪和体验，从PAT模型（Person-Artifact-Task model）入手，探求用户自身特征、社区的工具特征、知识共享任务特征对心流体验产生的影响以及心流体验与持续知识共享意愿之间的关联。[方法/过程]论文以百度知道社区的活跃用户为调查对象，回收205份有效问卷，利用Amos21.0软件对数据进行结构方程模型分析。[结果/结论]研究发现，知识问答社区用户自身特征中的技能水平、感知控制力、兴趣，社区工具特征的互动性、感知易用性，以及任务特征的挑战性对其心流体验的产生有正向影响；按照影响程度降序排列，依次为感知易用性、技能水平、感知控制力、互动性、兴趣；用户产生的心流体验越强，其持续参与知识共享的意愿越强；心流体验在除了清晰目标之外的其他6个自变量与持续知识共享意愿之间的中介作用得到了验证。在此基础上，论文从强化用户粘性、激发兴趣、提升互动等方面探讨对知识问答社区管理实践的启示。
