Measures
Participants’ engagement with each application was measured using eye tracking metrics and a self-report measure. The selection of eye tracking metrics reported in the present study was chosen from a broader range of eye tracking data automatically produced by the software Eyeworks. The self-report measure was modeled off of work by Fisher, Dobbs-Oates, Doctoraff, and Arnold (2012), who assessed children’s engagement in paper and pencil mathematics tasks. This measure indexes engagement with the hypotheses that engaging applications are more enjoyable to use.
