This practicum report describes an intervention during the 1990-1991 school year that involved restructuring a kindergarten classroom to include more developmentally appropriate activities. Expected outcomes were stated in the following terms: (1) the arrangement of the classroom will allow free, orderly movement; (2) the county's kindergarten curriculum will be incorporated into classroom activities; (3) the classroom will provide opportunities for active learning and will require fewer paper and pencil tasks; and (4) the number of discipline referrals of kindergarten children will decrease. The intervention involved rearranging the classroom into learning centers; color coding the centers; devising a management system for using the centers; and developing games and activities that correlated with the county's kindergarten curriculum. The success of the intervention was measured by comparing pre- and post-intervention teacher surveys and experimenter observational checklists on developmentally appropriate classroom practices, and by comparing the number of discipline referrals during the intervention year as against the previous year. Results indicated that the objectives were met. A reference list of 40 items is provided. Appendices include copies of the teacher survey and experimenter checklist, a guide for interviewing teachers, and a collection of class schedules and other items relevant to the implementation of developmentally appropriate practices in the classroom.
