This document reports on a 2-year study of the influence of males on the development of children and impact of male aides on child-care activities. The study originally developed from clinical observations and research results concerned with effects of fathers' absence on children and adolescents. The first year of the program was for demonstration purposes and did not involve control groups. Eight high school age males were trained and placed in two day care centers as educational aides. One center was located in a middle class neighborhood, and the other in an economically disadvantaged area. In the second year of the project, two more centers were added, as well as control centers where no males were placed. The report describes the operations of the project anecdotally as well as with data from structured observations and psychological testing. (DP)
