A program adapting precision teaching in an urban elementary school is described. This program, initiated by the Teacher Corps, was used as an inservice project operating in the classroom. Four major procedural steps are described: (1) the teacher must describe an educational objective in exact terms; (2) pupil performance must be recorded daily in terms of rate per minute for tasks; (3) if pupil data indicates the pupil is not learning, some aspect of the teaching process must be changed; and (4) if the teaching change does not improve performance, another change must be made. One aspect of this teaching method is maintaining a performance chart for each pupil that indicates individual growth and allows any needed teaching process changes to be made within a few days. An evaluation of the program is included in this report, as well as a description of the development of the program, the personnel, and budget. (JD)
