Two papers are included in this report. "Control and Feedback in the Environment of a Computer Tutor" investigates some control and feedback properties of a tutorial environment comprised of a student, his computer tutor, and the designer of the computer tutor. Three classes of computer tutor are described: rigid, generative, and knowledgeable. These classes are distinguished by an increase of the interactions among tutor and student and a decrease of the control of the tutor over the tutorial environment. Full partnership between tutor and student could be achieved with the help of programs that understand natural language. "Review in CAI: The Problem and an Implemented Solution" discusses review of material, which is made necessary by human memory loss. The computer tutor that incorporates review is built around performance programs that know what the student is to learn, generator programs that generate problems the student must learn to solve, and extensive diagnostic programs that guide the tutor in his interaction with the student. Borrowing compiler-writing techniques, a multi-level system for review has been implemented that avoids extra coding and repetition of material in identical form. (Author/JK)
