Four research projects were conducted on the improvement of individualized instruction. Two methods of teaching foreign language were examined. In the first, the computer stored a profile of the student's previous performance in German vocabulary, and it developed a strategy to teach the student additional German words. The second project tested the effectiveness of a special keyword association method to maximize the retention of Spanish and Russian vocabulary. The second two projects were computer-assisted courses in computer programing: Algebraic Interpretive Dialogue (AID), and BASIC Instructional Program (BIP). In both, the computer combines the student's history and the structure of the curriculum to construct the optimal teaching strategy. (EMH)
