DEVELOPED WERE THE PLANS AND PROCEDURES NECESSARY TO INTRODUCE A COHERENT SCIENCE PROGRAM INTO THE ELEMENTARY SCHOOLS OF TWO SCHOOL DISTRICTS BY USING UNITS FROM VARIOUS DEVELOPMENTAL CENTERS UNDER NON-EXPERIMENTAL CONDITIONS. EMPLOYING A GENERAL EDUCATION COORDINATOR WHO WORKED WITH TEACHERS HAVING A MINIMUM AMOUNT OF PREPARATION IN THE SCIENCES, THE STUDY SOUGHT TO DISCOVER THOSE MATERIALS DEVELOPED BY SCIENCE STUDY CENTERS WHICH COULD BE READILY ADAPTED TO THE SCHOOL PROGRAM. IT STUDIED THE WORKING ARRANGEMENTS BETWEEN DARTMOUTH COLLEGE AND THE PARTICIPATING SCHOOLS, AND ORGANIZED PRELIMINARY IN-SERVICE TRAINING FOR TEACHERS WHO WOULD BE INTRODUCING THE NEW MATERIALS. THE PRINCIPAL RESULT WAS THE DEVELOPMENT OF A THREE-YEAR CURRICULUM IMPROVEMENT PROPOSAL. THIS PROPOSAL (1) OUTLINED THE REQUISITE PRE-SERVICE AND IN-SERVICE TRAINING NEEDED IN THE DISTRICTS, (2) CALLED FOR FURTHER WORK BY THE COORDINATOR AT THE SCIENCE STUDY CENTERS, (3) PRESENTED A TRY-OUT SCHEDULE IN THE SCHOOLS FOR A THREE-YEAR PERIOD, AND (4) IDENTIFIED PARTICULAR UNITS, GRADE BY GRADE, THAT WOULD MAKE UP THE PROGRAM IN SCIENCE.
