This study was made to see if there were descriptive statistics on (1) size of enrollment, (2) location (by population density), (3) availability of staff, (4) curriculum (transfer or terminal), and (5) cost per student that would predict rejection of experimental programs in staff use. The attitude of the chief administrator as the single most important factor in adoption or rejection of an experiment was also tested. Experiments selected for study were (1) team teaching, (2) class size variations, (3) teacher aides, (4) language laboratories, and (5) television. It was found that (1) team teaching was affected by enrollment, location, and number of staff, (2) class size variations by enrollment, location, number of teachers, and cost per student, (3) use of teacher aides by enrollment and location, (4) use of language labs by enrollment, location, availability of staff, and type of curriculum, and (5) use of TV by enrollment, location, and availability of staff. The chief administrator's attitude toward a particular experiment was shown (in four of the five experimental programs) to have more effect on adoption or rejection than such concerns as lack of funds, staff, or space. The study recommends other pertinent research projects. (HH)
