In Novak's “concept mapping”, fully constructed “concept map” is shown to subjects before and/or after mapping work. As it takes too much time to get satisfactory results, in this study map completion tasks were introduced. Subjects were to insert some of the suitable concepts or lines into the blanks to make up the map wholly. In preliminary experiments the difficulty of getting satisfactory results were tested. In Exp. I, map completion task with some blanks of concepts are found to be the most effctive. In Exp. II, time spent on this task were manipulated. Subjects had negative effects when only 5 minutes were allowed. When 25 minutes were spent on this task in a 50 minute-experiment, subjects had the best positive effects.
