THIS PROJECT EXPLORED (1) INDIVIDUAL DIFFERENCES AMONG LEARNERS WHICH MAY BE DIFFERENTIALLY RELATED TO FILM LEARNING VERSUS CONVENTIONAL OR "LIVE" LEARNING, AND (2) INDIVIDUAL DIFFERENCES AMONG INSTRUCTIONAL FILMS WHICH MAY BE RELATED TO THEIR INSTRUCTIONAL EFFECTIVENESS OR TO IMPORTANT LEARNER CHARACTERISTICS. TWO SEPARATE STUDIES WERE CONDUCTED. THE FIRST STUDY USED THE SIMILAR EXPERIMENTAL DESIGN OF THE 1961 TENDOM STUDY. THE SECOND STUDY WAS PLANNED AS A FACTOR ANALYSIS. THE FILMS, ORIGINALLY PRODUCED BY TENDOM (1961), AND THE ACCOMPANYING PRINTED SCRIPTS WERE REVIEWED INTENSIVELY TO LOCATE THOSE FILM PRODUCTION VARIABLES WHICH APPEARED TO VARY AMONG THE FILMS IN THE SERIES AND WHICH COULD BE QUANTIFIED SATISFACTORILY AND MEANINGFULLY AS INDIVIDUAL DIFFERENCES AMONG THE FILMS. THREE INDIVIDUALS PARTICIPATED IN THE ANALYSIS. CONCLUSIONS FOR THE FIRST STUDY SEEMED TO INDICATE THAT PERSONAL CHARACTERISTICS OF LEARNERS DETERMINE, TO A SIGNIFICANT EXTENT, THE AMOUNT OF LEARNING DERIVED BY INDIVIDUAL MEMBERS OF THE AUDIENCE IN A GIVEN LEARNING SITUATION. RESULTS OF THE STATISTICAL ANALYSIS ARE SUMMARIZED IN SYMBOLIC FORM. THE SECOND STUDY CONCLUSIONS INDICATED THAT, AFTER FACTOR ANALYSIS OF 34 VARIABLES, SIX FACTORS WERE PROPOSED TO ACCOUNT FOR THE VARIANCE OBSERVED. THEY ARE (1) AUDIOVISUAL COMPLEXITY, (2) AUDIOICONICITY, (3) VIDEO ICONICITY, (4) TEMPORALITY, (5) ARTIFICIALITY, AND (6) INTERNAL REPETITION. SIX HYPOTHESES WERE SUGGESTED BY THE CLUSTERS OF VARIABLES. EVIDENCE SHOWED THAN AN INSTRUCTIONAL FILM, WHILE IT IS INHERENTLY AN EXTREMELY COMPLEX COMBINATION OF PRODUCTION CHARACTERISTICS, CAN BE ANALYZED MEANINGFULLY AT AN ELEMENTAL, PHYSICALISTIC LEVEL.
