OBJECTIVES OF THIS STUDY WERE TO COMPARE THE LEARNING OF PIANO KEYBOARD SKILLS BY CONVENTIONAL INSTRUCTION AND BY AN "ELECTRONIC KEYBOARD TUTOR" (EKT) DEVICE, BOTH PROVIDING MONITORING, AND IMMEDIATE FEEDBACK. THE EKT PROVIDES VISUAL FEEDBACK ONLY--IT IS A SYSTEM OF ELECTRIC SWITCHES CONNECTED TO A PIANO KEYBOARD. EDUCATION STUDENTS INITIALLY AT THREE LEVELS OF PIANO PROFICIENCY IN A MUSIC FUNDAMENTALS COURSE WERE ASSIGNED BY CLASS TO THE INSTRUCTIONAL MODES. MULTIPLE MEASURES OF PROFICIENCY INCLUDED PERFORMANCE RATINGS BY THREE JUDGES, AND AMOUNT OF PRACTICE TIME REQUIRED TO REACH A CRITERION PERFORMANCE LEVEL. ANALYSIS OF VARIANCE SHOWED THAT FOR INITIALLY PROFICIENT STUDENTS, EITHER INSTRUCTIONAL METHOD IS ADEQUATE, BUT FOR NAIVE STUDENTS, THE CONVENTIONAL METHOD IS SUPERIOR. ALSO, PRACTICE TIME WAS SIGNIFICANTLY DIFFERENT BETWEEN THE TWO INSTRUCTIONAL METHODS. STUDENT ATTITUDES TOWARD THE EKT WERE NEUTRAL, AND INSTRUCTOR ATTITUDES VARIED. RELUCTANCE TO PRACTICE ON THE EKT IS DISCUSSED. (LH)
