HONEYWELL USED AN AUDIO-PROGRAMED COURSE IN LISTENING SKILLS, CONSISTING OF A SERIES OF TAPED STATEMENTS OF VARYING LENGTH AND COMPLEXITY, WITH CONSIDERABLE NOISE, AND THE TRAINEE MADE A WRITTEN OR ORAL RESPONSE. IT TOOK 2.5 TO 3 HOURS TO COMPLETE, PLUS AN ADDITIONAL 1/2 HOUR FOR PRE- AND POST-TESTING. THE FIRST GROUP SHOWED TWOFOLD TO THREEFOLD INCREASE IN AVERAGE SCORES. WITH ANOTHER GROUP OF EMPLOYEES, THE PRE- AND POST-TESTS WERE REVERSED, AND IT WAS FOUND THAT THE AVERAGE SCORE AT THE END OF THE PROGRAM WAS LOWER THAN AT THE BEGINNING. IT WAS CONCLUDED THAT THE POST-TEST WAS EASIER THAN THE PRETEST. TWO PERSONS AT HONEYWELL TOOK THE PRETEST AND IMMEDIATELY THE POST-TEST (WITH NO TRAINING) AND SHOWED BETTER THAN A TWOFOLD INCREASE. A COMPARISON OF THE TESTS SHOWED THAT THERE WERE DIFFERENT NUMERICAL POINT VALUES FOR CORRECT RESPONSES. THERE WAS GREATER MATHEMATICAL PROBABILITY THAT THE TRAINEE WOULD SCORE BETTER ON THE POST-TEST. ADVERSE CONSEQUENCES OF THIS INCLUDE FALSE IMPRESSIONS OF AMOUNT OF LEARNING AND OVEREVALUATION OF THE COURSE. SOME IMPROVEMENT WAS ACHIEVED BY THE TRAINING, BUT CAUTION IS URGED IN SELECTING TRAINING PROGRAMS FOR LISTENING SKILLS.
