The purpose of this report is to try to identify some of the characteristics of those teachers most successful in providing a learning environment for their classes, and to describe some of the things which seem to be effective in motivating children to learn and enjoy both the process and the achievement of learning. To find a qualified group of outstanding teachers of the disadvantaged, school systems or projects which in the view of responsible evaluators could be considered successful or promising in educating their problem-burdened populations were identified; and then were identified the specific school unit within those projects which best fulfilled the objectives of the programs. Seven teachers in six different situations in cities across the country were observed. A study of these six cases, a description of which comprises the major part of this report, is considered to give some basis for checking the description of the model presented by the principals of the schools studied of their "best" teachers. This model was characterized as charismatic, compassionate, intelligent, emotionally mature, hard working, highly creative, and knowledgeable: the model understands the learning process and works well with parents and community people, and has high expectations for achievement by students and demands of herself and them that these expectations be fulfilled.
