Designed for use by prospective elementary school teachers and teachers currently involved in reading instruction, this book is a programed text on the fundamentals of decoding--phonemic and morphemic analysis--using both mastery learning and reviews of each lesson and each section. The sections deal with vowel phonemes, long vowel phoneme-grapheme generalizations, other vowel phoneme-grapheme generalizations, consonant phonemes, consonant phoneme-grapheme generalizations, structural analysis, syllabication, and accenting. In the two appendixes, major decoding generalizations are considered and sources on the utility of those generalizations are listed. (LL)
