AutoTutor: an intelligent tutoring system with mixed-initiative dialogue
TLDR
Grounded in constructivist learning theories and tutoring research, AutoTutor achieves learning gains of approximately 0.8 sigma (nearly one letter grade), depending on the learning measure and comparison condition.Abstract:
AutoTutor simulates a human tutor by holding a conversation with the learner in natural language. The dialogue is augmented by an animated conversational agent and three-dimensional (3-D) interactive simulations in order to enhance the learner's engagement and the depth of the learning. Grounded in constructivist learning theories and tutoring research, AutoTutor achieves learning gains of approximately 0.8 sigma (nearly one letter grade), depending on the learning measure and comparison condition. The computational architecture of the system uses the .NET framework and has simplified deployment for classroom trials.read more

Physiological-based emotion recognition with IRS model
Chao Li,Zhiyong Feng,Chao Xu +2 more
TL;DR: A Group-Based IRS model is proposed by adaptively matching a suitable recognizer in accordance with user's IRS level by categorizing users into distinct groups and the new user's emotion state is predicted by the corresponding emotion recognizer.

Integrating Temporal Information Into Knowledge Tracing: A Temporal Difference Approach
TL;DR: A temporal difference Bayesian knowledge tracing model (TD-BKT) is proposed to incorporate temporal difference information into knowledge tracing to eliminate the defect of BKT model and show great improvement in assessing online examinees’ knowledge state quantitatively.

An introduction to latent semantic analysis
TL;DR: The adequacy of LSA's reflection of human knowledge has been established in a variety of ways, for example, its scores overlap those of humans on standard vocabulary and subject matter tests; it mimics human word sorting and category judgments; it simulates word‐word and passage‐word lexical priming data.

Cognitive Tutors: Lessons Learned
TL;DR: The 10-year history of tutor development based on the advanced computer tutoring (ACT) theory is reviewed, finding that a new system for developing and deploying tutors is being built to achieve the National Council of Teachers of Mathematics (NCTM) standards for high-school mathematics in an urban setting.
