This report presents results from an analysis of the adult basic education (ABE) reading instruction research base, focusing on principles derived from the research and a future research agenda. After an introduction, Chapter 2 presents methods used to select and evaluate research related to ABE reading instruction. Chapter 3 serves as an index to the ABE and K-12 reading instruction research findings that appear in Chapters 4-9. Chapters 4-8 focus on these major aspects of reading instruction: assessing students to describe their reading "profiles" or overall reading ability; alphabetics instruction; fluency instruction; vocabulary instruction; and reading comprehension. Computer technology is covered in Chapter 9. Each chapter presents these items: (1) a description of the major aspect of reading covered, including a definition and rationale and, when appropriate, assessment; (2) major questions related to ABE reading instruction associated with specific topics of interest to ABE practitioners; (3) answers to questions in the form of emerging principles or trends when research addressed the questions; (4) summary of the research related to each principle or trend; and (5) ideas (and comments) for ABE reading instruction derived from K-12 reading instruction research. Chapter 10 summarizes important findings and presents an agenda for future research. Appendixes include 25 background references and 71 study references. (YLB)
