Teaching case-based argumentation through a model and examples

- Education
- 1997
It is a novel result that students can learn basic argumentation skills by studying computer-generated examples, which means that an instructional system does not necessarily need to rely on a very sophisticated understanding of students' arguments, which would be a significant obstacle to developing such systems.
Toward Meta-cognitive Tutoring: A Model of Help Seeking with a Cognitive Tutor

The research focuses on the hypothesis that an intelligent tutoring system that provides guidance with respect to students' meta-cognitive abilities can help them to become better learners, and creates a preliminary model that captures both effective and ineffective help-seeking behavior.

- 23 June 2008
A new method for instantiating Bayesian Knowledge Tracing is offered, using machine learning to make contextual estimations of the probability that a student has guessed or slipped, which allows for more accurate and reliable student modeling in ITSs that use knowledge tracing.
The Cognitive Tutor Authoring Tools (CTAT): Preliminary Evaluation of Efficiency Gains

- 26 June 2006
Preliminary small-scale controlled experiments involving basic Cognitive Tutor development tasks found efficiency gains due to CTAT of 1.4 to 2 times faster, and it is expected that continued development of CTAT will lead to further efficiency gains.

- 19 June 2000
Data about students' use of the help facilities of the PACT Geometry Tutor, a cognitive tutor for high school geometry, suggest that students do not always have metacognitive skills to support students in learning domain-specific skills and knowledge.
An Interview Reflection on “Intelligent Tutoring Goes to School in the Big City”
- K. Koedinger, V. Aleven
- EducationInternational Journal of Artificial Intelligence…
- 1 March 2016
This study was one of the first large-scale classroom evaluations of the integrated use of an Intelligent Tutoring System (ITS) in high schools and showed that a new algebra curriculum with an embedded intelligent tutoring system dramatically enhanced high-school students’ learning.
