TO DETERMINE THE RELATIVE IMPORTANCE OF CHEMISTRY AND PHYSICS FOR INSTRUCTION IN ELECTRICAL AND ELECTRONIC TECHNOLOGY, 51 TECHNICAL WORKERS, 51 JUNIOR COLLEGE INSTRUCTORS, AND 11 EXPERTS RATED 240 SCIENTIFIC PRINCIPLES AS TO THEIR VALUE IN A TECHNICIAN'S WORK. THE THREE GROUPS AGREED ON THE RANK ORDER OF 15 TOPICS--(1) CURRENT ELECTRICITY, (2) STATIC ELECTRICITY, (3) MAGNETISM, (4) ATOMIC ENERGY AND RADIATION, (5) SOUND, (6) THE MECHANICS OF SOLIDS, (7) THE STRUCTURE OF MATTER, (8) LIGHT, (9) HEAT, (10) THE MECHANICS OF GASES, (11) THE MECHANICS OF LIQUIDS, (12) THE CHEMICAL NATURE OF MATTER, (13) THE GENERAL PROPERTIES OF ENERGY AND MATTER, (14) IONS IN SOLUTIONS, AND (15) SOLUTIONS AND COLLOIDS. THE APPENDIX GIVES THE RANK ORDER OF MAJOR TOPICS AND OF ITEMS WITHIN THOSE TOPICS AND THE RANK ORDER OF ITEMS WITHIN THE WHOLE LIST. IT WAS CONCLUDED THAT A RANKING OF TOPICS FOR GENERAL EDUCATION WAS NOT SUITABLE FOR SPECIFIC OCCUPATIONAL COURSE PLANNING. (EM)
