An adjunct faculty member at a community college implemented and evaluated a practicum intervention designed to develop a teacher in-service education program promoting parental involvement and fostering communication between home and school. A series of sequenced in-service workships provided teachers and administrators with knowledge, understanding, and skills related to parental involvement in children's learning at personal, practical, and conceptual levels. Each in-service workshop included a pretest/posttest and a discussion of: (1) federal, local, state, and corporate policies which might affect parents and teachers; (2) family backgrounds directly influencing parental involvement in the schools; (3) effective communication skills; (4) methods for effectively conducting parent-teacher conferences; and (5) methods for increasing home-school cooperation and parental involvement. An evaluation was conducted in order to determine the most and least effective activities and materials in each in-service course. Workshops were offered to early childhood and elementary education teachers and administrators employed by a county school district. Results were positive. Teachers and administrators gained personal, practical, and conceptual knowledge, understanding, and skills concerning parental involvement in children's learning. Appendices provide measures and related materials; a 40-item reference list is included. (RH)
