ON THE EFFECT OF MAP-COMPLETION WORK ON C ONCEPT-LEARNING IN SCIENCE

In Novak's ''concept mapping'', fully constructed ''concept map'' is s hown to subjects before and/or after mapping work. As it takes too muc h time to get satisfactory results, in this study map completion tasks were introduced. Subjects were to insert some of the suitable concept s or lines into the blanks to make up the map wholly. In preliminary e xperiments 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 man ipulated. Subjects had negative effects when only 5 minutes were allow ed. When 25 minutes were spent on this task in a 50 minute-experiment, subjects had the best positive effects.
