A well-organized set of phonics rules will enable the reader to identify many words which are in his vocabulary, but which he has not encountered before in print. The rules must be sequenced in a manner that capitalizes on their applicability to the vocabulary of the typical reader. This can be achieved only when the rule set is defined on a properly delimited set of lexicon items. The work done in this project produced a vocabulary set containing approximately 9000 words (mostly base words). About two-thirds of this total consisted of the one- and two-syllable words that served as the data base for developing the spelling-to-sound correspondence rules. In effect, this would indicate that, in spite of its limited scope, the project has developed vocabulary and phonics information which can serve as a good starting information base for reading instruction programs in the early grades. This document describes the project and its results in detail. Its sections include: (1) background and rationale; (2) selection and organization of vocabulary words; (3) correspondence rules and a pronunciation key for the phonetic symbols used; (4) description of the printouts, tables, and lists containing the vocabulary-rules data, and an explanation of their use; and (5) rule-frequency tables and lists of particular printout data. The printouts are contained in ten separate books. (DO)
