Center for Innovation in Education Dekodiphukan Storybook Dekodiphukan Description A children’s storybook written in rhyme. The first of the fourteen apps that comprise the Baratta-Lorton Reading Program. The Reading Program is a reading and writing curriculum for beginning readers and any child who has already experienced difficulty in learning to read. 99% unique – 100% effective - 100% free Background for the fourteen apps The Baratta-Lorton Reading Program also known as Dekodiphukan (pronounced decode if you can) was developed by the Center for Innovation in Education whose many other offerings include Mathematics Their Way, the first non-traditional math curriculum adopted in by the State of California. Dekodiphukan has been in use in classrooms across the United States and Canada since 1985. The Program has been used to teach thousands of children to read and to write regardless of background or supposed lack of reading readiness. To date, no child using the program in a classroom setting has ever failed to learn to read or to write. This Dekodiphukan reading and writing curriculum is now a series of fourteen apps plus a parent-guide for the iPad that, within a period of six months to a year (or occasionally a bit longer for some special needs children), will enable every child using it to read and to write. Reading with enjoyment. Writing creatively. Dekodiphukan is a full fledged curriculum. It is a set of specific learning activities, not a set of games. The curriculum’s fourteen apps are all free with no ads - popup or otherwise - included. While the apps may be downloaded all at once and stored in a folder on the iPad, no more than two or three of the apps are used at any one time by the child. Dekodiphukan Storybook The first of the Fourteen Apps Forty-four sounds or phonemes form the building blocks for every word spoken in English. The Dekodiphukan Storybook, written in rhyme, introduces children to these forty-four sounds and connects each sound to a picture that represents that sound. It is easier to correctly identify the sound of a phoneme when the phoneme is at the end of a word.  Rhyming is used to facilitate correct sound-phoneme pronunciation. The events in the storybook provide the rationale for why each of forty-four sound pictures represents the particular sounds that it does. The Dekodiphukan Storybook is meant to be read initially by the parent to the child.  A play button provides an audio reading for each page to assist parents who are unsure of pronunciations, or who prefer to listen along with their child as the story is being read.  The audio reading of each page also permits the child to “read” and “reread” the storybook as often as he or she wishes, without waiting for an adult reader. Dekodiphukan STORYBOOK A children’s storybook written in rhyme Also available in book form through the Center’s website Introduces the 44 sounds of the English language Uses rhyme for clarity in sound identification To be read the first time by the parent to the child Parents unclear about pronouncements may play audios Child uses audio play buttons for subsequent readings Downloadable sound pictures for wall posting Downloadable Sound Summary for Parents
