THIS STUDY-SURVEY TO DETERMINE HOW AVAILABLE AUDIOVISUAL (AV) RESOURCES ARE USED IN U.S. PUBLIC SCHOOLS FOLLOWED AN EARLIER SURVEY WHICH INVENTORIED THE ACTUAL AMOUNTS OF PUBLIC SCHOOL, AV MATERIALS AND EQUIPMENT (SEE ED 003 758). IN THE CURRENT STUDY SOME 11,000 EDUCATIONAL PERSONNEL IN 247 SCHOOL DISTRICTS PARTICIPATED BY MEANS OF QUESTIONNAIRE RESPONSES. QUESTIONNAIRES WERE DESIGNED TO ELICIT ANSWERS WHICH COULD BE USED IN STATISTICAL TABULATIONS, DESCRIBING THE UP-TO-DATE PARAMETERS OF AV INSTRUCTION (FACILITIES, USE, AND OPINIONS). OF THE SCHOOL DISTRICTS SURVEYED, ESSENTIALLY ALL OF THEM HAD AT LEAST ONE 16-MM. PROJECTOR, SLIDE-FILMSTRIP PROJECTOR, AND RECORD PLAYER FOR EACH OF THEIR SCHOOLS. MOST OF THE SCHOOLS HAD TAPE RECORDERS, AND THE MAJORITY OF THE SECONDARY SCHOOLS HAD ONE OR MORE OPAQUE PROJECTORS, TELEVISION SETS, AND OVERHEAD PROJECTORS. COLLECTIONS OF AV MATERIALS WERE HIGHLY VARIABLE BOTH AS TO TYPE AND AMOUNT OF MATERIAL. AV COORDINATORS WERE EMPLOYED IN 90 PERCENT OF THE SCHOOLS, AND MOST OF THESE FUNCTIONED CHIEFLY AS SUPPLY OFFICERS ON A PART-TIME BASIS WITH LITTLE TIME TO ADVISE TEACHERS PERSONALLY. TEACHERS WHO WERE QUESTIONED MORE OFTEN USED AV MATERIALS AS SUPPLEMENTAL TEACHING AIDS THAN AS AN INTEGRAL PART OF THE TEACHING PROCESS. ELEMENTARY TEACHERS WERE FOUND TO USE AV MATERIALS MORE FREQUENTLY THAN SECONDARY TEACHERS. ONLY SCIENCE, FOREIGN LANGUAGE, AND MUSIC TEACHERS WERE FREQUENT USERS IN THE HIGH SCHOOLS. ADMINISTRATORS WERE MORE INCLINED THAN TEACHERS TO EXPAND AV PROGRAMS IN THEIR SCHOOLS. (JH)
