This document describes a practicum established to improve the learning environment in an urban elementary school. Violence, vandalism, and anti-social behavior on the part of students created a situation in which teachers spent more time keeping order in the classroom than in actual teaching. The practicum was set up as an inservice education project with the aim of changing teacher behavior in the classroom and thereby changing children's behavior. Teacher training sessions, in which teachers were encouraged to explore their classroom behaviors in order to begin establishing a helping/supportive relationship with students, were the basic elements of the project. Continuing evaluation and examination of personal attitudes were encouraged. Performance of students and changes in their behavior were observed, and tests were conducted before and after the three-month project. Emphasis was placed upon teachers establishing a sensitivity to the problems of the students and reacting to them in a helpful way. The practicum established that teacher behavior affects the learning situation, that teacher behavior can be changed, and that the change can improve student learning. Appendixes supply information on the characteristics of the school and community involved, the questionnaires used, and tests and survey data. A bibliography is included. (JD)
