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 Configurable Conversational Agent to Trigger Students’ Productive Dialogue: A Pilot Study in the CALL Domain
TL;DR: The study results indicate that ‘weak’-directed agent interventions can be more effective than undirected interventions by means of increasing the level of explicit reasoning, and thus productive dialogue in students’ productive dialogue.

The components of paraphrase evaluations
TL;DR: The results suggest that semantic and syntactic evaluations are the primary components of paraphrase quality, and that computationally light systems such as latent semantic analysis (semantics) and minimal edit distances (syntax) present promising approaches to simulating human evaluations of paraphrases.

Entrepreneurship Education and Sustainable Development Goals: A literature Review and a Closer Look at Fragile States and Technology-Enabled Approaches
TL;DR: In this article, a systematic review of entrepreneurship education and training (EET) in less-stable areas of the world is presented, which identifies several gaps in research and practice that potentially hinder EET from adequately advancing sustainable development, including a dearth of research on fragile states and demographic diversity.

Socially capable conversational tutors can be effective in collaborative learning situations
TL;DR: This paper describes an evaluation of a socially capable conversational tutor that supports teams of three (or more) learners in a design task and demonstrates that the socially capable tutor achieves significantly higher learning gains than the neutral, purely task focused tutor and learning gains not significantly different from the human capability “gold standard” tutors.

The impact of system feedback on learners' affective and physiological states
TL;DR: After receiving positive feedback from AutoTutor, learners mostly experienced ‘delight' while surprise was experienced after negative feedback, which indicated that tutor feedback and learner affect were related.

Affective Computing
TL;DR: Key issues in affective computing, " computing that relates to, arises from, or influences emotions", are presented and new applications are presented for computer-assisted learning, perceptual information retrieval, arts and entertainment, and human health and interaction.

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.

Intelligent tutoring systems
TL;DR: Computer tutors based on a set of pedagogical principles derived from the ACT theory of cognition have been developed for teaching students to do proofs in geometry and to write computer programs in the language LISP.

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.
