A new curricular router created to be more flexible, more user-oriented, and use less computer memory was developed in 1979. Although initially called the "Indiana Routing System" (TIRS), it has been renamed the "Indiana Manager of PLATO-Assisted Curricula." This new router permits any mixture of the instructional strategies of topic sequences, free indexes, and criterion-based instruction. In using the router, instructors proceed through the following tasks: choosing the topics, ordering them, deciding whether topics are elective or required, specifying the number of questions to be given on the pretest and posttest, establishing the passing score on the pretest, assigning the computer assisted curriculum to students, and examining student performance data. It is possible to develop a different curriculum for each student or for small groups of students. Curricular applications of the router in Indiana University's English Department have so far been confined to sections of special basic English skills composition classes, in which it complements and often supplements classroom activities or provides additional exercise in prerequisite skills. A similar application is found in the university's Learning and Study Skills Center, which provides short classes and tutorial help to develop student classroom and study skills such as notetaking, reading, and writing. All nine class sections of the journalism class, Writing for Mass Media, are using the routing system, which also can be used by instructors of any subject. (SW)
