1) Middle school students often use the internet for schoolwork, but their online reading tends to be cursory, fragmented, and opportunistic without guidance. 2) The study found that software called IdeaKeeper that provided reading prompts helped slow students' reading and make it less cursory, less fragmented, and less opportunistic by guiding their attention. 3) Prompted online reading with IdeaKeeper was found to be more deliberate, thorough, and purposeful than unguided reading. The software helped mediate students' online reading process.
