New publication in Behavior & Information Technology: Common Ground in learning with chatbots
The paper "Common ground improves learning with conversational agents" by Anita Körner, Antonia Tolzin, Andreas Janson, Jan Marco Leimeister and Ralf Rummer has been published in the journal Behavior & Information Technology ( Impact Factor 3.1, VHB-WI Ranking B).
In a field-experimental study, the interdisciplinary team from the University of Kassel and the University of St. Gallen shows that learners learn better with a pedagogical conversational agent (so-called PCA) when the agent actively promotes the development of a common ground of knowledge. Specifically, students were equipped with two functionally identical PCAs - one variant repeatedly asked comprehension questions and invited brief confirmations or follow-up questions (common ground PCA), while the control variant did not. Result: significantly better test results and longer, more in-depth interactions with the common ground PCA. The study is part of the Komp-HI project (funded by the Federal Ministry of Research, Technology and Space and the Hessian Ministry of Science and Research, Arts and Culture).
