This practicum identified the problem of inconsistent use of developmentally appropriate practices by staff in an early childhood center and implemented an inservice program to increase the use of activities based on individual appropriateness rather than on age alone. The solution strategy utilized a self-assessment survey of classroom practices to identify staff perceptions. Ongoing inservice training was implemented, based on the survey, observations, and consultations with staff. The inservice sessions included large- and small-group training, consultations with staff, development of individualized goals, peer support teams, and a parent education component. Evaluation results indicated an increase in developmentally appropriate practices as well as other positive changes, although the established outcome levels were not attained. One unanticipated result was that following the implementation period, fewer staff responded that children engaged primarily in self-directed and open-ended activity. (Seven appendices include the classroom practices survey form, inservice agendas and evaluation form, inservice summaries, and an annotated bibliography. Contains 66 references.) (AP)
