一个成功外语学习者的二语动机自我系统个案研究

二语动机研究在近几十年成为二语习得研究的一个重要领域,而近五年来＂自我＂和＂身份＂概念的引入使得二语动机研究朝着一个更加动态的视角转变。借鉴Drnyei的＂二语动机自我系统＂理论与Ushioda的＂情境中的人＂的相对观,采用个案研究的方法,通过对一个成功的外语学习者Bill的访谈、反思日志以及博客质性数据的搜集分析,探讨其在学习英语过程中动机自我系统的动态构建,发现其＂理想二语自我＂、＂应该二语自我＂及其＂学习经验＂之间存在交互关系,并且其动机二语系统有两种独特表现形式,即＂努力行为＂以及＂英语功能观＂。     

姿态控制系统设计与仿真

在刚性运动学建模的基础上,根据PID控制理论针对俯仰、偏航、滚转通道分别设计控制器,进行姿态控制。在设计好控制器的基础上,再分别设计干扰补偿器,利用前馈补偿,减弱干扰对系统性能的影响,改善其控制性能,并设计仿真平台,进行仿真验证。     

从英法语言干扰的角度来看法语教学

对于有一定英语基础的法语学习者来说,常因受到英语的干扰而在学习过程中产生错误。针对这种现象,从语言干扰的理论出发,结合法语教学对象的特点,在语音、词汇和句法层面分析英法语言干扰情况,探讨如何处理这些干扰情况,以期指导法语教学,提高教学质量。

Response: Dempster and Corkill's “Interference and Inhibition in Cognition and Behavior: Unifying Themes for Educational Psychology”

Dempster and Corkill present a persuasive case for the utility of the concepts of interference and inhibition in their review, Interference and Inhibition in Cognition and Behavior: Unifying Themes for Educational Psychology. We were especially attracted to their drawing attention to the role of inhibition in learning and to the argument that closer links of educational psychology to neuroscience are needed. At a general level of analysis, we agreed that the concepts of interference and inhibition can provide a unifying framework for describing phenomena in several areas of inquiry, but these concepts seemed to us to be less useful for understanding structured, meaningful learning in instructional domains. Overall, we viewed Dempster and Corkill's review as a creative effort that usefully redirects our attention to neglected basic learning processes.

Assessing motivational styles of students in the south-east Asian context of Singapore

High levels of academic achievement in Asian educational systems have generated interest in the study of motivational patterns of students in these contexts. The objectives of this paper are firstly, to provide a review of existing literature on the study of motivational styles amongst students and secondly, to identify the occurrence of different motivational styles amongst students in Singapore,. The method of identifying different motivational styles was adapted from a procedure first developed by Craske (1988). The findings of this study indicate that although the distribution of motivational styles amongst the Singaporean students was consistent with that as obtained by Craske, there was a higher tendency for maladaptive motivation amongst the males than the females. In contrast, Craske found no gender differentiation, though earlier researchers had found that maladaptive motivation was more common among the females.     

蜜蜂种间交尾的干扰是生存竞争中一种特殊形式

在中华蜜蜂(中蜂)和意利蜜蜂(意蜂)种间生存竞争中,而中峰成为失势者,数量锐减、密度下降、生栖范围缩小,在意蜂占绝对优势的情况下,中蜂处女王交尾受到意蜂雄蜂严重干扰的结果,交尾成功率极低或交尾不成。这种干扰是生存竞争中的特殊表现形式,成为中蜂在平原丘陵地区繁衍困难,而又不被人们注意的重要原因。

再论母语在第二语言习得中的正负迁移作用

母语在第二语言习得的过程中，既起着积极的作用，又起着消极的作用，既能帮助第二语言学习，又能妨碍第二语言学习。因此，母语在第二语言习得中存在正向迁移，又存在着负向迁移。对此，应正确加以处理。
