This practicum report describes a 13-week intervention that facilitated the participation of parents of 16 preschoolers in the instruction of their children. Objectives of the intervention were that: (1) parents and children would participate in take-home projects and workshops; (2) parents and children would increase the amount of time they spent together every week performing developmentally appropriate problem-solving activities; and (3) parents would increase the amount of time they spent in volunteer classroom activities. Every week, each child was to take home a "parent suitcase" that contained developmentally appropriate materials relating to a particular type of activity. Children were to work on the materials with their parents and return the "suitcase" the following week. The intervention also involved discussion groups and workshops on developmentally appropriate practices for parents. Results indicated that all parents and children participated in the use of the "parent suitcase." Nearly 70 percent of parents increased the amount of time they spent with their children in developmentally appropriate activities as measured by pre- and postintervention questionnaires. Parents exhibited an increase of 165 percent in classroom volunteer time. Appendices include a copy of the parent questionnaire, copies of communications to parents, checklists relating to the "suitcases," and descriptions of activities contained in the "suitcases." Some materials from the "suitcases" are also attached. (BC)
