This study examined the effects of training poor readers in story mapping procedures to improve their reading comprehension. Story mapping is a schema-building technique that teaches students to organize narrative stories using an underlying story grammar framework. Five intermediate elementary students with mild learning disabilities and poor comprehension received story mapping instruction. The results showed that four of the five students improved in their ability to answer comprehension questions about stories and maintained this improved performance after the intervention ended. Three students also showed improved comprehension of more difficult classroom reading materials. The study provides support for using story mapping as an effective technique for improving the reading comprehension of struggling readers.
