Higher Contributions Correlate with Higher Learning Gains

Students interacted with an Intelligent Tutoring System called Operation ARIES!,which involves two agents interacting with the human in natural language trialogs. We investigated the conditions in which the length of the students’ contributions is correlated with learning. Word count and the proportional learning gains scores were correlated, especially in the later phases of the curriculum. The link between student contribution length and learning supports previous findings in human one-on-one tutoring.
