The Teaching Information Processing Systems (TIPS) is an elaborate and flexible computer program designed to amplify effective classroom instruction. It enables teachers to give individual instruction to large numbers of students, maintains student characteristics and achievement data, generates student progress reports, prescribes remedial or enrichment work, and reports individual and collective student performance in areas within the course. TIPS requires detailed course planning in advance, including scheduling of each unit and subdivision of learning objectives into conceptual areas. Surveys, performance criteria, and proficiency prescriptions must also be established. In experimental use at Riverside City College, two Macroeconomics classes were included in a pilot project with a third class used as a control. TIPS use was the only difference in instructional treatment. Regression analysis indicated that TIPS raised student performance on exams an average 6.7 points, yielding a 10% improvement at the .05 level. Constraints included budget, computer capacity, and the necessity of a TIPS Assistant to relieve the instructor of computer time demands. A complete model for the Macroeconomics class and sample TIPS readouts are appended. (RT)
