TAILIEUCHUNG - Báo cáo khoa học: "The role of positive feedback in Intelligent Tutoring Systems"

The focus of this study is positive feedback in one-on-one tutoring, its computational modeling, and its application to the design of more effective Intelligent Tutoring Systems. A data collection of tutoring sessions in the domain of basic Computer Science data structures has been carried out. A methodology based on multiple regression is proposed, and some preliminary results are presented. A prototype Intelligent Tutoring System on linked lists has been developed and deployed in a collegelevel Computer Science class. . | The role of positive feedback in Intelligent Tutoring Systems Davide Fossati Department of Computer Science University of Illinois at Chicago Chicago IL USA dfossa1@ Abstract The focus of this study is positive feedback in one-on-one tutoring its computational modeling and its application to the design of more effective Intelligent Tutoring Systems.

The research community is working on discovering the characteristics of tutoring. One of the goals is to understand the strategies tutors use in order to design effective learning environments and tools to support learning. Among the tools particular attention is given to Intelligent Tutoring Systems ITSs which are sophisticated software systems that can provide personalized instruction to students in some respect similar to one-on-one tutoring Beck et al. 1996 . Many of these systems have been shown to be very effective Evens and Michael 2006 Van Lehn et al. 2005 Di Eugenio et al. 2005 Mitrovic et al. 2004 Person et al. 2001 . In many experiments ITSs induced learning gains higher than those measured in a classroom environment but lower than those obtained with one-on-one interactions with human tutors. The belief of the research community is that knowing more about human tutoring would help improve the design of ITSs. In particular the effective use of natural language might be a key element. In most of the studies mentioned above systems with more sophisticated language interfaces performed better than other experimental conditions. An important form of student-tutor
