This report gives details of an inservice program designed to help teachers learn and understand the Mathematics Continuous Progress-Skill Mastery Program and Management System in Chicago schools. The program consists of locally-developed curriculum guides and behavioral objectives, criterion-reference tests, and mastery record key-sort cards. Fourteen inservice staff meetings are discussed, and the program evaluated on a set of 20 goals for teachers. Questionnaires completed by teachers and outside evaluators are tabulated. Behavioral objectives and criterion-referenced tests were judged to be useful components of the management system. Possible changes in the mastery record cards are discussed. No reference is made to actual classroom teaching materials. (JBW)
