This report documents the creation and evaluation of materials for the Carroll County, Maryland, elementary school science curriculum. Based on a 1983 pilot study and implementation of this program, funding was secured from the National Science Foundation for evaluation of the program. The principal investigating agency was the Carroll County Board of Education, working in conjunction with the Maryland State Department of Education, Hood College and the University of Maryland. The program provided preservice training for all teachers, follow-up workshops, program evaluation and identification, training and support of science coordinators in each school. The evaluation found the locally develped program to be significantly (p less than .001) better than two textbook approaches to which it was compared in amount of hands-on activity, inclusion of scientific processes, student motivation and teacher motivation. It was significantly more difficult (p less than .001) to implement then the textbook approaches. The bulk of the document consists of appendices which include statements of principles, pilot designs, duties of coach, operational definitions of processes, congruence with state framework, kit contents, supplemental text lists, live material center description, summer program information, and evaluations of Parent-Teacher presentations, the pilot study, and workshops.
