Comparison of two methods of using programmed learning

It has been generally concluded that programmed learning can teach. The problem has been one of determining just how the programmed materials should be used. Some experimenters have tried programmed learning with no supplementation and experienced no ill-effects in attitude or in achievement over the short instructional time period of a few days or a few weeks, but they predicted that in a longer study signs of boredom on the part of the learner would develop. It has been demonstrated that the usc of programmed materials for a longer period of time does not have particularly detrimental effects upon attitude toward the subject or toward programmed learning when the programmed materials are supplemented with teacher instruction. 1
