TO DETERMINE THE EXTENT OF PUBLIC SCHOOL USE OF PROGRAMED INSTRUCTION, EDUCATIONAL RESEARCH SERVICE CONDUCTED A QUESTIONNAIRE SURVEY OF 126 SCHOOL SYSTEMS IN 44 STATES. IN 1960-61, THE FIRST YEAR OF REPORTED USE, 12 SCHOOL SYSTEMS WERE USING PROGRAMED INSTRUCTION. BY 1964-65 THIS USE HAD INCREASED EIGHT TIMES AND USE BY STUDENTS 20 TIMES. MATHEMATICS AND ENGLISH REMAINED THE MOST POPULAR SUBJECTS FOR PROGRAMED INSTRUCTION, MAKING UP 80.4 PERCENT OF THE 378 APPLICATIONS REPORTED. GRADE PLACEMENT OF APPLICATIONS RANGED FROM KINDERGARTEN TO GRADE 12, WITH APPROXIMATELY TWO-THIRDS OF THE APPLICATIONS A PART OF REGULAR COURSE WORK AND ONE-THIRD, REMEDIAL OR ENRICHMENT. OTHER USES REPORTED WERE--IN SUMMER SCHOOL SESSION, WITH THE PHYSICALLY HANDICAPPED AND HOMEBOUND STUDENTS, IN ADULT EDUCATION, IN JUNIOR COLLEGES, AND IN TEACHER ORIENTATION AND INSERVICE TEACHING. ELAPSED TIME OF PROGRAMS VARIED FROM ONE WEEK TO ONE YEAR. ONLY 23 OF THE SYSTEMS IN THE SURVEY REPORTED ANY USE OF TEACHING MACHINES. SUMMARIES OF USE, SPECIFYING GRADE LEVELS, SUBJECTS, NUMBER OF STUDENTS IN THE PROGRAM SESSION, AND ELAPSED TIME OF EACH PROGRAM, ARE LISTED BY SCHOOL DISTRICTS. THIS REPORT WAS PUBLISHED IN "EDUCATIONAL RESEARCH SERVICE CIRCULAR," NO. 7, SEPTEMBER 1966 AND IS AVAILABLE FOR $1.75 FROM EDUCATIONAL RESEARCH SERVICE, 1201 SIXTEENTH ST., NW, WASHINGTON, D.C. 20036.
