This report consists of three documents: the report proper, the abstract, and appendixes. The major objective of the project was to demonstrate the adaptability of the IPI System (Individually Prescribed Instruction) to the needs of ABE centers. This was accomplished by field testing the IPI program, modified for adults, in a number of ABE centers. The tests indicate that administrative and teacher training programs must be modified, and a variety of materials distribution and organizational models are needed to meet the requirements of the different ABE centers. The "streamlining" of the elementary program resulted in: the new ILA (Individualized Learning for Adults) Mathematics Continuum, presented in five areas rather than 13; the average number of pages in a skill booklet has been reduced; and the Placement Testing procedures have been simplified. The program has also been broadened to include an Applications Area, and the upper level of all areas include topics to assist the student in preparing for the GED examination. The Reading program is being extended into a Communications Skills program. Data collected for the evaluation served four purposes: Description of the Field Test Sites; Evaluation of the Implementation of the IPI System; Program Content Modification; and Estimation of Student Gain. Results of the ILA Mathematics Achievement Test show that students do learn in the Adult-IPI system. (Author/DB)
