This 35-page booklet, available online or as a printable PDF, is produced by The National Academies Press. It is based on the report Improving Adult Literacy Instruction: Options for Practice and Research, created by a committee of experts convened by the National Research Council at the request of the U.S. Department of Education in order to "synthesize research on literacy and learning in order to improve instruction for those served in adult education in the U.S."

Improving Adult Literacy Instruction: Supporting Learning and Motivation:

• "Describes principles of effective instruction to guide those who design and administer adult literacy programs and courses"
• "Explores ways to motivate learners to persist in their studies, which is crucial given the thousands of hours of study and practice required to become proficient"
• Looks at "technologies that show promise for supporting individual learners and freeing busy adults from having to be in a particular place in order to practice their literacy skills"
• While "not intended as a how-to manual for instructors, teachers may also find the information presented here to be helpful as they plan and deliver instruction"
