An information feedback system for use in evaluating an educational program is described, and its effectiveness in evaluating the Follow Through program and its use in relation to the Iowa Tests of Basic Skills are discussed. The systems approach to program evaluation consists of objectives clarification, decision making, and program planning. In the Follow Through project, the following components are recommended for an ideal information system: administration, dissemination, instruction, medical-dental, nutritional, psychological services, social services, parent involvement, and evaluation. Instruments are used in each component so that data can be gathered to register any progress toward component objectives. An example of instructional feedback in relation to reading achievement (second and third grades) is provided, and a feedback report for health services is presented in tabular format. Feedback sessions generally focus on three areas: (1) achievement problems, (test-taking skills, and (3) general problem solving skills. The test content of the Iowa Tests of Basic Skills is listed, as follows: Vocabulary, Word Analysis, Reading Comprehension; a sample of one class's item analysis of vocabulary is provided. The use of the Behavioral Maturity Scale is in the feedback to the teacher and the teacher aide about their perceptions of the maturity of each child. (For related documents, see TM 002 526-539.) (DB)
