PREVIOUS RESEARCH HAD SHOWN THAT SIMULATION COULD BE SUBSTITUTED FOR THREE OF SIX HOURS OF ACTUAL DRIVING INSTRUCTION, A CONCENTRATED COURSE OF INSTRUCTION COULD BE MORE EFFECTIVE THAN ONE OF SEVERAL WEEKS OR MONTHS, AND USE OF SIMULATOR MOVIES WITHOUT THE EQUIPMENT HAD VALUE. IN THIS STUDY, DATA ON HIGH SCHOOL STUDENTS IN HARRISBURG, PENNSYLVANIA WERE COLLECTED--AGE, SEX, GRADE AVERAGE, ATTITUDE, INTELLIGENCE, AND HOURS OF DRIVING OUTSIDE OF CLASS. PARTICIPANTS WERE RANDOMLY ASSIGNED TO ONE OF FIVE LEARNING SITUATIONS WITH VARYING LENGTHS OF PROGRAMS, AND USES OF SIMULATOR MOVIES AND EQUIPMENT, AND BEHIND-THE-WHEEL TRAINING. OTHER VARIABLES CONSIDERED IN EVALUATING TRAINING RESULTS WERE SCORES ON THE NEYHART ROAD SKILL CHECK LIST FOR PASSENGER CAR DRIVERS, THE NUMBER OF TIMES NEEDED TO PASS THE STATE DRIVING TEST, AND NUMBER OF TRAFFIC VIOLATIONS. STATISTICAL TECHNIQUES USED TO TEST FOR SIGNIFICANCE WERE COEFFICIENTS OF CORRELATION, CHI SQUARE, AND ANALYSIS OF VARIANCE AND COVARIANCE. IT WAS CONCLUDED THAT--(1) INSTRUCTIONAL TIME COULD BE REDUCED FROM NINE TO SIX HOURS IN THE SIMULATOR AND FROM SIX TO FOUR HOURS BEHIND THE WHEEL, AND (2), SIMULATOR MOVIES SHOWN WITHOUT EQUIPMENT WERE VALUABLE IN DEVELOPING DRIVING SKILLS, ATTITUDES, AND KNOWLEDGE.
