THE PROGRAM IS DESIGNED TO ASSESS UNDERSTANDING OF THE SCIENCE AND THE SCIENTIFIC ENTERPRISE OF PERSONS IN THE UNITED STATES. INDIVIDUALS WILL BE RANDOMLY SELECTED FROM 192 POPULATIONS. SUBGROUPS WILL BE ESTABLISHED ON THE BASIS OF GEOGRAPHIC REGION, RURAL-URBAN-SUBURBAN DIFFERENCES, SOCIOECONOMIC CLASS, AGE, AND SEX. OBJECTIVES FOR SCIENCE EDUCATION HAVE BEEN DEFINED AND TEST EXERCISES BASED ON THE OBJECTIVES WERE CONSTRUCTED DURING THE SUMMER OF 1966. EXERCISES WERE TO BE USED ON A TRIAL BASIS DURING THE FALL AND WINTER 1966-1967. INTERVIEWS AND OBSERVATIONAL PROCEDURES WILL ALSO BE USED TO OBTAIN INFORMATION ABOUT INTERESTS, HABITS, AND PRACTICES. PERCENTAGES OF RESPONSES OF TOTAL POPULATIONS WILL BE USED TO REPORT FINDINGS. FUTURE EVALUATIONS WILL BE MADE AND COMPARED WITH PREVIOUS RESULTS. THIS ARTICLE IS PUBLISHED IN "THE SCIENCE TEACHER," VOLUME 33, NUMBER 6, SEPTEMBER 1966. (AG)
