What makes reading instruction CORI?
CORI is a theoretical model of integrated instruction in reading and science, or reading and social studies. An overview of the CORI model has been given in numerous journal articles and books. The current research-based design of CORI is 10—12 weeks of instruction for 60-120 minutes daily for grades 3, 4, and 5 (or 45-80 minutes in middle school, grades 5—8). When implemented as designed, the elementary prototype (grade 3, 4, and 5) has produced statistically significant, experimental advantages on standardized reading comprehension tests, reading motivation, and science knowledge. CORI implementation (model or prototype) is expensive and time consuming. It requires several months of planning by 1 -3 full-time staff members, teacher professional development, and funds to purchase books, manipulatives, and materials necessary for instruction. Implementation of CORI requires approved use of the CORI Professional Development Participant Manual that comes with the Summer Institute Trainin
