In this study, anonymous audience data from the Molly of Denali app are analyzed. The overall aim of the study is to (a) understand how children interact with a Molly of Denali app, and (b) explore psychometric modeling using player responses to estimate a player's mastery of informational text (IT) features such as table of contents, captions, and diagrams.

Select findings: Children spent the most time in the app’s village of Qyah. A small percentage of players completed all game levels in Sled Dog Dash and Fish Camp: 0.4 and 4.1% respectively. In Fish Camp 54.7% mastered all three IT attributes, 32.0% mastered none. For Sled Dog Dash, 52.7% mastered all three, while 35.7% mastered none.
