Intelligent courseware is common

Grader A: partial

Adaptive tutoring software existed and was used: Carnegie Learning's Cognitive Tutor was offered in thousands of US schools, and 61-83% of teachers said students used technology to learn or practice basic skills. But most of this was drill software, not intelligent courseware, and it was a supplement, not a common means of learning. Online courses reached over a quarter of US college students in fall 2008, but most were not adaptive.

Test: At least 20% of students learning mainly through intelligent (adaptive) courseware: not met; adaptive tutors reached a measurable share (thousands of schools, over 5% by estimate) but below mainstream.
