Our experiment represented a limited interaction consisting of
a single lecture based on a single method of gauging student attention.
To more fully explore the potential benefits in utilizing
EEG-based review technology, future studies might examine
long-term learning effects or incorporate additional measurements
such as gaze or traditional embedded assessment to
corroborate the EEG signal. Additionally, future studies might
investigate differences in learning across subtopics for students
receiving adaptive EEG-based review. Although we found no
significant differences across topics within the adaptive condition,
we note that this analysis is limited due to our sample size
and the lack of a priori knowledge regarding which subtopic
students in the adaptive condition would review.
