The Stress of School Project attempted to find new ways by which the school can help children learn more effectively. The resulting information system, APPLE (Anecdotal Processing to Promote the Learning Experience) was designed to process anecdotal data obtained in schools and integrate it with quantitative measures of pupil characteristics. Many features of APPLE are oriented toward building and maintaining magnetic tape and disc files of a variety of types of educational data. The system is also generalized so that other school systems may use it. The basic features of the APPLE system, the APPLE storage and retrieval program and the APPLE supporting programs are specified. Types of behaviors incorporated in the system include: (1) academic-intellectual; (2) social-emotional; (3) physical appearance; (4) general; and (5) other. The APPLE data structure and the way data are organized into files give the system its potential as a research tool and its generalizability to a variety of administrative needs. The files are discussed quite thoroughly. (KJ)
