We study how student behaviors associated with disengagement differ between different school settings. Towards this, we investigate the variation in the frequency of off-task behavior, gaming the system, and carelessness in an urban school, a rural school, and a suburban school in the United States of America. This analysis is conducted by applying automated detectors of these behaviors to data...

We study how student behaviors associated with engagement differ across different school settings. We present a study to investigate the variation in gaming the system and off-task behavior in schools in the USA and Philippines, using quantitative field observations on students using the same Cognitive Tutor lesson on scatterplots. We find that students in the Philippines go off-task significan...

The effectiveness of intelligent tutoring systems at increasing learning might be improved if the systems were combined with collaborative activities that encouraged conceptual elaboration. We extended the Cognitive Tutor Algebra, an intelligent tutoring system for high-school mathematics, with a peer tutoring activity that was designed to encourage interaction, reflection, and accountability. ...

This case study illuminates contextual factors related to the tutor experience when senior students served as tutors for sophomore students in a problem-based learning (PBL) course in a baccalaureate dental hygiene program. Data were collected using various sources and methods. Tutors and administrators were interviewed, those tutored completed an anonymous questionnaire, the tutorial process a...

This thesis investigates issues surrounding the design and implementation of a digital drum tutor. People have been developing digital tutors in all fields of study in an attempt to replace or complement human instructors. This drum tutor aims to replace a human instructor in some cases, but mostly to guide a student’s practice sessions, which is where the most improvement occurs. While using t...

This paper introduces a cognitive tutor designed for second language grammar instruction. The tutor adopted Corbett and Anderson’s (1995) Bayesian knowledge tracing model and provided adaptive training on the English article system. We followed the Competition Model (MacWhinney, 1997) and understood the article system as a galaxy of cues determining article usage on the basis of form-function m...

Combining peer tutoring with an intelligent tutoring system (ITS) holds the promise of augmenting the current benefits of the ITS. We designed and implemented a peer tutoring approach as an addition to the Cognitive Tutor Algebra (CTA), an ITS for high school algebra. We then used 30 students to evaluate the potential of the peer tutoring addition to increase learning. Although students learned...

2001 3 ACKNOWLEDGMENTS I would like to thank my mentor, Professor Martha W. Evens, so much for her patience and guidance. I will never forget that she is always there whenever I need help. I also thank all of the CIRCSIM-Tutor project members and our domain experts at Rush Medical College. They have been so helpful with research and so friendly in life. I really appreciate all of the wonderful ...

We examine a corpus of reflective tutorial dialogues between human tutor and student after the student completed introductory physics problems, to predict when the tutor abstracted from the student’s preceding turn or when the tutor specialized from the student’s preceding turn. Tutor abstraction occurs when the tutor repeats a segment of the student’s turn using more general terms. Tutor speci...

Over the last few decades, there have been a rich variety of approaches towards modeling student knowledge and skill within interactive learning environments. There have recently been several empirical comparisons as to which types of student models are better at predicting future performance, both within and outside of the interactive learning environment. A recent paper (Baker et al., in pres...
