EFFECTS OF BRANCHING IN A COMPUTER-CONTROLLED AUTO-INSTRUCTIONAL DEVICE.
COULSON, JOHN E.; AND OTHERS
A STUDY ON THE EFFECTIVENESS OF USING BOTH THE STUDENT'S ERRORS ON TRAINING ITEMS AND HIS OWN EVALUATION OF HIS LEARNING PROGRESS WAS PRESENTED. TWO GROUPS OF 15 HIGH SCHOOL STUDENTS WERE GIVEN AUTOMATED INSTRUCTION ON LOGIC BY MEANS OF A FLEXIBLE SEQUENCE, COMPUTER-CONTROLLED AUTO-INSTRUCTIONAL DEVICE. ONE GROUP WAS DESIGNATED THE FIXED-SEQUENCE GROUP, AND THE OTHER WAS TERMED THE BRANCHING GROUP. EVERY MEMBER OF THE FIXED-SEQUENCE GROUP, AND THE OTHER WAS TERMED THE BRANCHING GROUP. EVERY MEMBER OF THE FIXED-SEQUENCE GROUP RECEIVED THE IDENTICAL SEQUENCE OF 233 INSTRUCTIONAL ITEMS. EACH STUDENT IN THE BRANCHING GROUP WAS GIVEN A DIFFERENT NUMBER AND SEQUENCE OF ITEMS, DEPENDING ON HIS PERFORMANCE IN RESPONDING TO CERTAIN ITEMS DURING THE LESSON, AND ON THE STUDENT'S SELF-EVALUATION OF HIS OWN PROGRESS. AT THE CONCLUSION OF THE LESSON A WRITTEN CRITERION TEST WAS GIVEN COVERING THE MATERIAL IN THE LESSON. THIS TEST WAS THE SAME FOR ALL MEMBERS OF BOTH GROUPS. THE AUTO-INSTRUCTIONAL DEVICE USED CONSISTED OF A GENERAL PURPOSE DIGITAL COMPUTER COUPLED TO A RANDOM-ACCESS SLIDE PROJECTOR AND AN ELECTRIC TYPEWRITER. THE 345 INSTRUCTIONAL ITEMS ON LOGIC INCLUDED SIMPLE AND COMPOUND STATEMENTS, LOGICAL CONNECTIVES, AND SIX ARGUMENT FORMS. MEMBERS OF THE BRANCHING GROUP AVERAGED 8.9 POINTS ON THE CRITERION TEST, AND REQUIRED AN AVERAGE OF 13.3 MINUTES LESS TRAINING TIME. THE DIFFERENCE IN CRITERION PERFORMANCE WAS SIGNIFICANT AT THE .05 LEVEL. THE DIFFERENCE IN TRAINING TIME DID NOT REACH SIGNIFICANCE. THE CORRELATION BETWEEN APTITUDE SCORE AND POST-TRAINING SCORE WAS NOT SIGNIFICANT FOR EITHER NOR FOR THE TWO GROUPS COMBINED.
