A student teacher who was concerned about a third grader's difficulties with her assignments, apparent low self-esteem, and anger observed the child in school for a 6-week period on Mondays, Wednesdays, and Fridays for 2 hours each day. For 2 weeks, the child was also observed at a recreational center on Mondays, Wednesdays, and Fridays for an average of 2.5 hours per observation. Finally, observations were conducted during the weekends the child spent with the student teacher as part of the student teacher's intervention. Data from the observations were used to formulate descriptions of the child's baseline behavior before and after the interventions. Peer interviews were conducted during three of the observations to determine how children in the classroom saw their relationship with the child. The interventions of the student teacher included introduction of appropriate behavior; an out-of-town field trip; and praise when it was warranted. As a result of the intervention, the student teacher realized that the child became more aggressive in school when community and family life became difficult for her. After the intervention, the child's work at school improved and the child seemed to take pride in her assignments. The time spent in school and with the student teacher appeared to provide the child with the confidence she needed to feel successful. (HOD)
