An ESEA Title III language development program, originating in Mifflinburg, Pennsylvania, is presented in 60 twenty-minute lessons to help prepare preschoolers for the reading experience. Four areas of language usage and reading readiness are stressed--auditory discrimination or phonology, letter discrimination, stylistics, and morphology, grammar, and syntax. The presentation recommends that verbal behavior be developed in a stimulus-response situation that reinforces conditioned oral responses through repetition and the use of various materials and motivational techniques. Numerous activities and exercises are included to develop in preschool children such language skills as the recognition of sound-symbol relationships, initial consonant and vowel sounds and blends, rhyming words, and complete sentences.
