This six-volume teacher workbook introduces the teacher to the design of the Individually Prescribed Instruction procedure (IPI)--particularly as it is applied in mathematics--and instructs him in the use of its objectives and tools through pretest-posttest lessons. Following initial lessons in the history and procedures of individualized instruction and the IPI system, four fundamental criteria of behavioral objectives (learner activities or products) are explained and related in volume 2 to the Mathematics Continuum, which permits individual placement and sequencing of students through elementary school in 13 areas (such as addition) at six levels of competency, determined through four types of achievement tests: placement, curriculum embedded, pretest, and posttest. Separate sections on each test type in volume 3 are calculated to train the teacher in diagnosing student achievement. The remaining three volumes develop the teacher's proficiency in planning prescriptions on the basis of his continuing analysis of test results and classroom observations provided in five simulated case studies (one in the form of an audio disc). IPI materials are reproduced throughout the document. Three explanatory 33 1/3 records accompany the six volumes when ordered from the publisher. (LP)
