Guest Editorial New and Interdisciplinary Approaches to Language and Cognition

This Special Section on Language and Cognition of Journal of Electronic Science and Technology（JEST） presents a collective of state-of-theart interdisciplinary research on language and cognition. It features empirical and theoretical studies on cognitive approaches to language, using a variety of methodological approaches, from behavioral measures to neuroimaging. The topics discussed are varied,ranging from language comprehension and acquisition to the language-emotion interactions, reflecting marked broadening of the research agenda in this field. We invite yet more integrated research to move the field forward.

A Study on Student Reflection in Asynchronous Online Text-stimulated Discussions

为了了解学生在网络协作学习中如何进行知识构建和互动,本研究探讨了学生在基于课文内容的非即时在线讨论中如何进行反思。研究着重识别学生参与讨论过程中反思的成份和应用的反思技能。根据建构主义理论的相关学说,这些反思技能被划分为个体认知反思技能和交际互动反思技能两类。通过分析学生在三次基于课文内容的非即时讨论中的帖子,发现学生反思的成份包含个人已有知识经验、课文内容、课外内容以及其他同学的见解,同时总结出学生在讨论过程中应用了十五种反思技能。此外,该研究还分析了学生所应用的各种反思技能的质量高低及各种反思技能被应用的频率。以这十五种反思技能作为最基本的分析单元,就可分析非即时在线讨论课文内容过程中的互动模式以及知识构建的模式和效果。
