Written as a follow-up to the first sourcebook published in 1967, this document seeks to address emerging issues in successful science supervision which have become important since 1967. Among the issues addressed are: (1) an increasing emphasis on the evaluation of students and programs; (2) demands for accountability; (3) changing working relationships with teachers and administrators; (4) emphasis on public relations; (5) concerns of safety and liability; and (6) need for flexibility by the science supervisor in the face of rapid change in science education.
