Concept-Oriented Reading Instruction (CORI) was developed in 1993 by Dr. John T. Guthrie with a team of elementary teachers and graduate students. The project designed and implemented a framework of conceptually oriented reading instruction to improve students' amount and breadth of reading, intrinsic motivations for reading, and strategies of search and comprehension. The framework emphasized five phases of reading instruction in a content domain: observing and personalizing, searching and retrieving, comprehending and integrating, communicating to others, and interacting with peers to construct meaning. CORI instruction was contrasted to experience-based teaching and strategy instruction in terms of its support for motivational and cognitive development.
