A Meta-Analysis of Advance Organizer Studies

Twenty-nine reports yielding 112 studies were analyzed with Glass’s meta-analysis technique, and results were compared with predictions from Ausubel’s model of assimilative learning. Overall, advance organizers were shown to be associated with increased learning and retention of the material to be learned. Levels of some variables in the high-effect-size studies were not as predicted by Ausubel’s model, however.
