TL;DR: The Andes system demonstrates that student learning can be significantly increased by upgrading only their homework problem-solving support, and its key feature appears to be the grain-size of interaction.

TL;DR: Atlas-Andes is a dialogue enhanced model tracing tutor (MTT) integrating the Andes Physics tutoring system with the Atlas tutorial dialogue system, providing Andes with the capability of leading students through directed lines of reasoning that teach basic physics conceptual knowledge, such as Newton’s Laws.

TL;DR: Five years of experimentation at the United States Naval Academy indicates that the Andes tutoring system significantly improves student learning.

TL;DR: The authors proposed two ways to improve model tracing tutors and in particular the Andes physics tutor: first, tutors should fade their scaffolding and integrate the knowledge they currently teach with other important knowledge in the task domain in order to promote deeper learning.

TL;DR: Two ways to improve model tracing tutors and in particular the Andes physics tutor are proposed, and it is argued that natural language processing is necessary for encouraging deeper learning.
