This report describes the development, implementation, and evaluation of a model for classroom observation designed to improve instructional supervisory skills and enhance teaching and learning. The project was carried out in 10 (Broward County, Florida) elementary schools with the principals and six teachers from each school involved. The aims of the project were to provide a model for observation and get principals to use it. The model was used by 10 principals and 40 teachers for four months. A Status Questionnaire and Principals' Responsibility Rank Order Form, each developed by the author, produced no significant differences in attitudes, understanding, philosophies or reactions to classroom stimuli during observation. Scriven's Product Evaluation Profile provided the assessment upon which conclusions were drawn about the model and overall project. Those people who reviewed and used the model support its implementation in other schools. (Author)
