Collected here are a number of varied materials on school supervision intended for secondary principals. These include a brief description of a presentation concerning school supervision; a number of visual aids, checklists, charts, and outlines used in the presentation; a short paper on the logistics of Supervision through Educational Management by Objectives and Results (STEMBOR); and an appendix to that paper containing a sample weekly school calendar notifying teachers of what is expected of them for that week, an outline of the sequence administrators should use for STEMBOR supervisory activities, a checklist of classroom routines, and a classroom observation form to be used when evaluating teachers. The papers and outlines describe a system applying management by objectives to school supervision; the other materials are to be used by principals in implementing the system. (JM)
