Although student engagement is correlated with academic success, the mechanism by which this attentional focus translates into improved performance is unknown. We hypothesized that the level of neural reliability evoked by educational stimuli, measured via the inter-subject correlation (ISC) of electroencephalography (EEG), would predict both attention to and retention of the stimuli. To assess this, the knowledge base of 20 subjects was assessed before and after exposure to educational videos. The reliability of each individual’s evoked responses, recorded while watching the videos, was compared to their peers to establish a metric for their relative attentional engagement with the stimuli. Neural reliability correlated with an improvement on test scores after exposure to the educational videos. ISC could also discriminate the attentional state of subjects with perfect accuracy. This suggests that ISC is a marker of the stimulus-related attentional mechanisms necessary to achieve comprehension. In the future, ISC may be used as a metric when designing and assessing educational content and presentation style.
