Insights into the analysis of elaborative discourse activities and their impact on argumentative reasoning

论证话语对论证推理发展的关键作用似乎有据可查。然而，需要在内容层面上进行更彻底的分析，以确定具体的相互关联的交际行为，以培养辩论能力和对给定主题发展综合观点。但是，好的对话论证的具体指标是什么？在这个项目中，我的目标是通过哥伦比亚大学的研究奖学金，将库恩斯教授和我自己的专业知识结合起来，来回答这个研究问题。虽然库恩教授主要侧重于研究辩论技巧的发展，但拟议的项目结合了她和我的研究，并基于已经收集到的数据：本项目将通过分析论述性话语特征，如发展反论点、挑战他人观点或就其对冲突信息处理的影响提供解释，拓宽研究和理论化论证的范围。为了实现项目的目标，我计划重新分析在Kuhns教授实验室收集的一项长期研究的数据子集。特别地，我们将研究语篇伙伴之间的相互作用。库恩教授和她的实验室擅长对过程进行编码，以找出先前的交流如何影响进一步的交流。在这种情况下，我可以获得对话语数据分析的经验。结合库恩教授和她的实验室成员的能力和我自己在内容分析方面的知识，我将开发一个编码方案，捕捉辩论话语中的各种交流动作。然后，将个体推理的质量和基于话语的最终解决方案作为依赖度量，应用结构方程建模来确定精细化话语活动与个体推理之间的相互关系。

The pivotal role of argumentative discourse for the development of argumentative reasoning seems well documented. However, a more thorough analysis on the content level is needed to identify specific interrelated communicative actions that foster the ability to argue and to develop an integrative perspective towards a given topic. But what exactly are indicators of good dialogic argumentation? With the proposed project I aim at answering this research question by bringing together Prof. Kuhns and my own expertise through a research fellowship at Columbia University. While Prof. Kuhn has primarily focused on the investigation of the development of argumentative skills, the proposed project combines her and my research based on data that have been collected already: The present project will broaden the scope of research and theorizing on argumentation by aiming at the analysis of elaborative discourse features, like developing counterarguments, challenging the others perspective or providing explanations with regard to their impact on the processing of conflicting information. To attain the goals of the project, I plan to re-analyze a subset of data from a long-term study that have been collected in Prof. Kuhns lab. In particular, the interplay between discourse-partners will be investigated. Prof. Kuhn and her lab are skilled in the coding of processes to find out how previous communication influences further communicational moves. In this context, I can gain experience in the analysis of discourse data. Combining the competence of Prof. Kuhn and her lab members with my own knowledge about content analysis I will develop a coding scheme capturing the variety of communicational moves in argumentative discourse. Then, the quality of individual reasoning and the final solution based on discourse are considered as dependent measures to determine the interrelations between elaborative discourse activities and individual reasoning by applying structural equation modeling.
