The four papers which comprise this booklet on supervision are entitled a) Human Resources Supervision; b) The Case for Staff Development; c) The Advisory System and Supervision; and d) Beyond Accountability. The introduction presents previous views of supervision and discusses implications of recent teacher entrenchment. The first paper contrasts human relations supervision with human resources supervision, and discusses motivational theory and job enrichment factors. The second essay strongly advocates staff development activities and proposes a professional growth model involving three components: attitudes, pedagogical skills, and substantive knowledge. The third paper examines the advisory system, which differs from other supervision theories in that it is predicated upon the assumption that teachers are concerned about improving their teaching and will do so given the proper support conditions. This paper lists and defines advisory functions and examines conditions affecting them. The final paper examines the conflict between accountability and improvement/innovation and sketches an evaluation model which is not limited to the dollar expenditure/measurable-results obtained theory of accountability.
