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

AutoTutor and affective autotutor: Learning by talking with cognitively and emotionally intelligent computers that talk back
TL;DR: AutoTutor is an intelligent tutoring system that helps students compose explanations of difficult concepts in Newtonian physics and enhances computer literacy and critical thinking by interacting with them in natural language with adaptive dialog moves similar to those of human tutors.

The Eras and Trends of Automatic Short Answer Grading
TL;DR: A comprehensive review of ASAG research and systems according to history and components concludes that an era of evaluation is the newest trend in ASAGResearch, which is paving the way for the consolidation of the field.
Five Major Shifts in 100 Years of Engineering Education The authors discuss what has reshaped, or is currently reshaping, engineering education over the past 100 years up until the current emphasis on design, learning, and social-behavioral sciences research and the role of technology.
TL;DR: In this article, five major shifts in engineering education are identified, including the first shift from hands-on practice to mathematical modeling and scientific analyses, and the last three shifts are in progress.

A Selective Meta-Analysis on the Relative Incidence of Discrete Affective States during Learning with Technology
TL;DR: In this article, a meta-analysis of 24 studies that utilized a mixture of methodologies (online self-reports, online observations, emote-aloud protocols, cued recall) and affect judges (students themselves, untrained peers, trained judges) for fine-grained monitoring of 14 discrete affective states of 1,740 middle school, high school, college, and adult students in 5 countries.

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.
