Science supervisors have a complex and difficult job. They must have the abilities, training, and experience of scientist, educator, administrator, and politician. A science supervisor must be a master teacher, both in practice and in the knowledge of teaching methods, research on learning, and insight into the development of children. Another important role of the science supervisor is the promotion and support of science teaching with teachers, administrators and the community. This sourcebook consists of a collection of 24 articles by various authors concerning six major areas of science supervision. These areas include: (1) trends for the future; (2) the viability of science programs and supervision; (3) staff development; (4) safety in laboratories and classroom facilities; (5) the evaluation of teachers and programs; and (6) research about science supervision.
