IslandPedia app. To address the need for students to access learning resources throughout their problem-solving episodes,
the virtual tablet includes the IslandPedia app (Fig. 3). IslandPedia provides students multimedia presentations of
key content. They are available on demand as students solve problems to successfully complete quests in the game, and
characters opportunistically recommend that students consult IslandPedia when needed. Accompanied by voiceover narration
with close captioning, IslandPedia’s presentations dynamically highlight salient visual elements. Presentations draw
connections between virtual objects and real-world phenomena. Authored in Flash and imported into CRYSTAL ISLAND through
the Unity game engine, some presentations are diagrammatic, while others are photographic.
