The third manual in the set of six manuals for training Head Start staff presents workshop module information on child development, social services, and parent involvement. The four child development workshops focus on (1) ways to plan for and group children to meet their individual needs, (2) teacher-child interactions that foster cognitive growth, (3) classroom management, and (4) methods for training volunteers to work in the classroom. The two social services workshops described are concerned with the process of interviewing staff members to determine which ones should be used to work with families. The first workshop focuses on interviewing skills, while the second deals with the use in interviewing of responses (statements in which the social service worker reacts to what parents have said) and leads (statements in which the social service worker expresses her own ideas and feelings and expects the parents to react to them). Hendouts are also included. (PCB)
