THE MEASUREMENT OF THE EFFECTIVENESS OF THE DOCUMENTARY SOUND-FILM AS A SUPPLEMENT IN THE TEACHING OF METHODS TO COLLEGE STUDENTS BEING PREPARED TO TEACH IN THE SECONDARY SCHOOLS.

THE PREPARATION AND ASSESSMENT OF DOCUMENTARY FILMS FOR USE IN METHODS INSTRUCTION OF COLLEGE STUDENTS WAS REPORTED. FOUR GENERAL SOURCES WERE USED FOR GUIDANCE IN THE SELECTION OF TOPICS FOR THE DOCUMENTARIES. THESE SOURCES INCLUDED COLLEGE TEXTBOOKS, COLLEGE CATALOGS, INTERVIEWS WITH SPECIALISTS, AND STUDENT INTERVIEWS. POSSIBLE TITLES, FILMS, SUBJECT CONTENT, AND GUIDELINES WERE OBTAINED FROM THESE SOURCES. INSTRUCTIONAL FILMS WERE THEN PREPARED AND USED IN METHODS CLASSES. STUDENTS ENROLLED IN THE CLASSES WERE ASSIGNED TO TWO CONTROL GROUPS AND ONE EXPERIMENTAL GROUP. EACH GROUP CONSISTED OF 40 STUDENTS. THE EXPERIMENT WAS CONTINUED DURING TWO FOLLOWING SCHOOL TERMS IN FOUR SUBJECT AREAS--SOCIAL STUDIES, MATHEMATICS, SCIENCE, AND ENGLISH. EVALUATIVE MEASURES WERE DEVELOPED AND ADMINISTERED BEFORE THE USE OF THE FILMS. THESE MEASURES IMPOSED PRE- AND POST-TEST DESIGN. THE AUTHOR CONCLUDED THAT EXPERIMENTAL GROUPS WERE AIDED BY THE FILMS IN AN UNDERSTANDING OF THE TEACHING PROCESSES, ALTHOUGH THE RESULTS WERE NOT STATISTICALLY SIGNIFICANT. FURTHER STUDY WAS SUGGESTED TO DETERMINE THE USEFULNESS OF THESE FILMS FOR A PROGRAM OF INSERVICE REEDUCATION OF TEACHERS IN BASIC TECHNIQUES OF TEACHING. (RS)
