When adult students arrive in the classroom, they can be at just about any level in their reading development, from beginning readers working on the fundamentals to more advanced readers ready to begin study for a high school level equivalency diploma. This Partnership for Reading publication summarizes the emerging principles and trends in adult reading instruction, and describes strategies proven to work by the most rigorous scientific research available on the teaching of reading. The research that confirmed the effectiveness of these strategies used systematic, empirical methods drawn from observation or experiment; involved rigorous data analyses to test its hypotheses and justify its conclusions; produced valid data across multiple evaluators and observations; and was accepted by a peer reviewed journal or approved by a panel of independent experts. The application of these research based strategies will increase the likelihood of success in reading instruction.
