Advance organizers activate the most suitable schema to learn new material. Poetic images are signified in schemata and the elements which are not expressed may be called by advance organizers. The purpose of this investigation is to discern the effectiveness of advance organizers on the signification of poetic images. Pretest-posttest experimental design with a control group was used in the study. The two sophomore groups from the Social Sciences Teaching department at Dokuz Eylul University formed the sample for the study. 74 students (36 in the experimental group, 38 in the control group) participated in the study. The experimental group was given advance organizers. Data were collected by the Achievement Test, measuring the signification of poetic images. There was a statistically significant difference (p less than 0.01) between the groups in the signification of poetic images after the treatment. The difference was in favor of the experimental group.
