This document evaluates the use of automatically generated questions in textbooks to promote active learning. It finds that engagement with automatically generated questions was similar to human-authored questions and not deterred. Difficulty levels of automatically generated questions also fell within the range of human-authored questions. Placement of questions in the course and whether they assessed recall or recognition impacted engagement. Very difficult questions reduced student persistence but easy questions did not. The evaluation suggests that automatically generated questions can effectively promote active learning without deterring students.
