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

Data-driven natural language generation using statistical machine translation and discriminative learning
TL;DR: It is proved that automatic corpus extension by means of paraphrase extraction and validation is just as effective as crowd-sourcing and being at the same time less costly in terms of development time and resources.

A Prompt Response Monitoring System for the Guiding Support of Learning Activities
TL;DR: The experimental results show that students got better grade and had less abnormal learning states with the proposed monitoring system, and the proposed system improves students’ learning outcomes.

Inclusive Decision Making: Applying Human Factors Methods to Capture the Needs and Voices of Marginalized Populations
TL;DR: In the face of large-scale climate change and growing populations, urban leaders must make strategic decisions about how to adapt their city and its neighborhoods to changing climate conditions as mentioned in this paper, and these decisions are particularly critical in low-resource neighborhoods where many residents face marginalization, and are often the most vulnerable to climate events.

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.
