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

A constraint-based furniture design critic
TL;DR: A computational model of design critiquing using the Furniture Design Critic program is proposed, which as a research tool helps to explain how to select Critiquing methods by considering specific conditions such as the user's knowledge level and the interaction history between the user and the system.

Understanding when students are active-in-thinking through modeling-in-context
TL;DR: This paper presents a novel, rubric‐based approach to develop automated student models for new activities that teachers develop in digital learning environments that promote active thinking and shows that a rubric-based approach can outperform a machine learning approach in this context.

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.
