A 1-year study was conducted to: document the effects of the Artists-in-Residence Program of the Music Center of Los Angeles County, Education Division (MCED); inform program planning and revision; and provide a compendium of evaluation strategies for future use. This study was divided into four phases and used a variety of methods: (1) questionnaires administered to 503 students, 54 teachers, 21 parents, 12 artists, 9 administrators, and 9 school-residency coordinators; (2) systematic observations in classrooms (12 hours); (3) focus group interviews with staff and artists; and (4) analyses of report card grades for 20 classes and attendance data for the 503 students. Overall, the results are positive. Students learned, maintained, and generalized knowledge and skills presented by the artists and demonstrated gains in subject matter grades, written and oral communication, and problem-solving behaviors. Program goals and operation were considered good, and the artists were found to be competent professionals. Strategies (questionnaires) for future evaluations, a 27-item annotated bibliography, the 1989-90 schedule of the MCED's residencies, and responses to the questionnaires and the evaluation meeting questions are provided in appendices. Twenty tables summarize study data. (SLD)
