Underscoring the need for improved supervision and evaluation policies as a means of increasing public confidence in the quality of education in Massachusetts public schools, this yearbook presents six articles describing supervision and evaluation innovations. Specific topics include a summary of recommendations compiled by the Study Committee in Evaluation Personnel; a description of the manner in which evaluation can improve the quality of education; a discussion of clinical supervision, in which classroom observation is the basis for teacher evaluation; the presentation of a rating scale for assessing teacher performance; a description of supervisory modeling, where the supervisor actually teaches a lesson to demonstrate desirable techniques; and a summary of the supervisory approach, in which supervision and evaluation are based upon explicit teacher expectations and objectives.
