THIS STUDY WAS DESIGNED TO DETERMINE THE FEASIBILITY OF INTRODUCING A COURSE IN OCEANOGRAPHY AT THE SECONDARY LEVEL. SPECIFIC OBJECTIVES WERE (1) TO ORGANIZE, EXAMINE, AND REVISE EXISTING INSTRUCTIONAL MATERIALS SUITABLE FOR USE IN AN INDEPENDENT STUDY COURSE IN OCEANOGRAPHY, (2) TO DEVELOP NEW INSTRUCTIONAL MATERIALS AND EXPERIENCES, (3) TO MEASURE THE EFFECTIVENESS OF THE VARIOUS INSTRUCTIONAL MATERIALS AND MEDIA, (4) TO ASSESS THE FEASIBILITY OF INVOLVING SEVERAL NEIGHBORING SCHOOL DISTRICTS, AND (5) TO ASSESS HOW WELL STUDENTS, PURSUING A COURSE THROUGH INDEPENDENT STUDY, LEARN VOCABULARY AND BASIC CONCEPTS, DEVELOP LABORATORY AND ANALYTICAL SKILLS, AND APPLY KNOWLEDGE FROM PREVIOUS RELATED COURSES. THE PROGRAM INVOLVED 24 STUDENTS CHOSEN FROM VALHALLA HIGH SCHOOL AND FOUR NEIGHBORING HIGH SCHOOLS ON THE BASIS OF THE STUDENTS' SCIENCE AND MATH BACKGROUNDS AS WELL AS THEIR INTEREST IN OCEANOGRAPHY. THE PROGRAM CONSISTED OF 30 THREE-HOUR LECTURES BY OCEANOGRAPHERS ASSOCIATED WITH THE LAMONT GEOLOGICAL OBSERVATORIES. THE LECTURERS PROVIDED OCEANOGRAPHIC EQUIPMENT, SPECIMENS, FILMS, SLIDES AND RECORDS, AND OTHER MATERIALS USED IN THE PROGRAM. LABORATORY EXPERIENCES, PROJECTS, AND FIELD TRIPS WERE CONDUCTED. PRETESTING AND POST-TESTING OF STUDENTS WERE CONDUCTED, AND THE RESULTS ARE INCLUDED IN THE REPORT. THE PROGRAM DIRECTOR IN CONJUNCTION WITH CONSULTANTS FROM LAMONT GEOLOGICAL OBSERVATORY AND WOODS HOLE OCEANOGRAPHIC INSTITUTION DEVELOPED COURSE OUTLINES, A REFERENCE BOOK, AND SCIENTIFIC AMERICAN REPORT LISTS. THESE MATERIALS ALONG WITH OTHER REFERENCE AND RESOURCE MATERIALS, WHICH WERE MADE AVAILABLE TO THE PARTICIPATING SCHOOLS, ARE INCLUDED IN THE REPORT. THE INVESTIGATION INDICATED STUDENTS THROUGH INDEPENDENT STUDY COULD INTERRELATE THE AREAS OF SCIENCE THEY STUDIED. (DS)
