摘要

在本文中,我们探讨了使用潜在语义分析(LSA)、批评系统和知识构建来支持英语作文的计算机教学。我们建立并测试了一个英语作文评论系统,该系统利用LSA来分析学生的作文,并通过将学生的作文与教师的示范作文进行比较来计算反馈。将LSA值输入到评判组件中,为学生提供用户界面。软件代理还可以使用评论反馈来协调与多个用户(学生和教师)的协作知识构建会话。共享的反馈提供了种子问题,可以引发讨论和对下一阶段写作的延伸反思。我们展示了我们建立的原型的第一个版本,并报告了三个实验的结果。我们在论文的最后描述了我们对未来工作的计划。

Grounding Collaborative Learning in Semantics-Based Critiquing
In this paper we investigate the use of Latent Semantic Analysis (LSA), Critiquing Systems, and Knowledge Building to support computer-based teaching of English composition. We have built and tested an English Composition Critiquing System that makes use of LSA to analyze student essays and compute feedback by comparing their essays with teacher’s model essays. LSA values are input to a critiquing component to provide a user interface for the students. A software agent can also use the critic feedback to coordinate a collaborative knowledge building session with multiple users (students and teachers). Shared feedback provides seed questions that can trigger discussion and extended reflection about the next phase of writing. We present the first version of a prototype we have built, and report the results from three experiments. We end the paper by describing our plans for future work.

期刊介绍: Discussions of computational methods, algorithms, implemented prototype systems, and applications of open and distance learning are the focuses of this publication. Practical experiences and surveys of using distance learning systems are also welcome. Distance education technologies published in IJDET will be divided into three categories, communication technologies, intelligent technologies.
