THERE IS A DICHOTOMY WHICH EXISTS IN EDUCATION AND--IN PARTICULAR, IN THE DOMAIN OF MUSIC LEARNING--IN THE ASSUMPTION THAT INDIVIDUAL DIFFERENCES IN LEARNING ARE MET IN A LARGE GROUP-INSTRUCTION PROGRAM. THE MAIN OBJECTIVE IN THE RESEARCH WAS TO TEST AND TO EVALUATE A CLINICAL TYPE OF INSTRUCTIONAL PROGRAM BASED ON INDIVIDUAL DIFFERENCES IN SUCH A MANNER THAT DIAGNOSES COULD BE MADE AND INDIVIDUAL'S MUSIC AILMENTS COULD BE TREATED IN LEARNING THREE BASIC MUSIC ELEMENTS. PHASE I WAS AN ITEM ANALYSIS OF STUDENT WORKSHEETS AND TEST PAPERS ACCUMULATED FROM USING AUTO-INSTRUCTIONAL METHODS IN PAST RESEARCH. PHASE II WAS A DISCRIMINATIVE ANALYSIS SO THAT PREDICTIONS COULD BE MADE FOR THE SELECTIVE AUTO-INSTRUCTIONAL TREATMENT OF INDIVIDUALS. PHASE III WAS AN EXPERIMENT USING THOSE FRESHMEN MUSIC STUDENTS WHO WERE ENROLLED IN THE FUNDAMENTALS OF MUSIC COURSE AT THE OHIO STATE UNIVERSITY IN THE ACADEMIC YEAR 1966-67. FROM THE RESEARCH IT WAS POSSIBLE TO DISTINGUISH INDIVIDUALS AND GROUPS AS A PARTICULAR TYPE OF LEARNING PROBLEM, WHICH COULD BE DEALT WITH ON AN INDIVIDUAL-GROUP BASIS, WITH THE PREDICTED GAIN SCORES ESTABLISHED.
