THIS DIRECTORY CONTAINS BRIEF DESCRIPTIONS OF EACH OF THE 84 COOPERATIVE COLLEGE-SCHOOL SCIENCE PROJECTS (CCSS) OF THE NATIONAL SCIENCE FOUNDATION (NSF). CCSS PROVIDES OPPORTUNITIES FOR COLLEGES AND UNIVERSITIES TO COLLABORATE WITH SCHOOL SYSTEMS IN BRINGING ABOUT IMPROVEMENTS IN ELEMENTARY AND SECONDARY SCHOOL SCIENCE AND MATHEMATICS. THE PROGRAM SUPPORTS PROJECTS WHICH DEAL WITH PROBLEMS OF A NATURE AND COMPLEXITY THAT WARRANT THE COOPERATIVE EFFORTS OF A SCHOOL SYSTEM AND AN INSTITUTION OF HIGHER EDUCATION. TWO EXAMPLES OF THE PROJECTS SUPPORTED BY CCSS ARE THE FOLLOWING--(1) A SCHOOL SYSTEM IN NEED OF EXPERT ADVICE ON THE KINDS OF CHANGES THAT SHOULD BE MADE IN ITS MATHEMATICS OR SCIENCE PROGRAM REQUIRES ASSISTANCE IN TRAINING TEACHERS AND IN INTRODUCING NEW PROGRAM MATERIALS TO STUDENTS - A GRANT FROM THE CCSS PROGRAM ENABLES A NEAR-BY COLLEGE OR UNIVERSITY TO PROVIDE THE EXPERT ASSISTANCE WHICH THE SCHOOL SYSTEM NEEDS, AND (2) A SCHOOL SYSTEM DECIDES TO IMPROVE ITS SCIENCE OR MATHEMATICS PROGRAM NOT BY INTRODUCING A NEW CURRICULUM, BUT BY TAKING REMEDIAL MEASURES TO MODERNIZE AND IMPROVE THE EXISTING COURSES - A COLLEGE COLLABORATING WITH THE SCHOOL SYSTEM PROVIDES THE INSERVICE INSTRUCTION NECESSARY TO ENABLE THE TEACHERS TO CARRY OUT SUCH REFORMS. AS SHOWN IN THE EXAMPLES, THE PROJECTS INVOLVE A DOUBLE COMMITMENT. THE SECONDARY SCHOOLS COMMIT THEMSELVES TO THE REFORMS IN THEIR SCIENCE OR MATHEMATICS PROGRAMS WHICH HAVE BEEN DEVELOPED AS A RESULT OF THE COLLABORATION, AND THE COOPERATING HIGHER EDUCATIONAL INSTITUTION ASSUMES THE RESPONSIBILITY TO ASSIST THESE SCHOOLS.
