  • Patent number: 7270546
    Abstract: A reading or language interactive system which utilizes a mechanism to permit a computer-based instruction program in reading or language instruction to implement a shared reading program, wherein portions of the text are read by the student and portions by the computer itself. The proportion of the text “read” by each participant and the pace at which the lesson progresses can each be automatically altered based upon the proficiency of the student. In addition, the system utilizes a computer instructor to share the task of reading or language learning by modeling the task for the learner, variably controlling the amount of material that the student reads aloud based upon a computer assessment of the student's ability, helping the learner navigate through the instructional application, and participating in a joint performance that demonstrates the student's reading.
