Expressive NLG for Next-Generation Learning Environments: Language, Affect, and Narrative

Recent years have seen the appearance of adaptive learning technologies that offer significant potential for bringing about fundamental improvements in education. A promising development in this arena is the emergence of narrative-centered learning environments, which integrate the inferential capabilities of intelligent tutoring systems with the rich gameplay supported by commercial game engines. While narrative-centered learning environments have demonstrated effectiveness in both student learning and engagement, their capabilities will increase dramatically with expressive NLG. In this talk we will introduce the principles motivating the design of narrative-centered learning environments, discuss the role of NLG in narrative-centered learning, consider the interaction of NLG, affect, and learning, and explore how next-generation learning environments will push the envelope in expressive NLG.
