Center for Innovation in Education Two-Sound Flipbook Description The second 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. Two-Sound Flipbook The second the Fourteen Apps Three purposes for the Flipbook First, to allow the child to learn the sounds. Dekodiphukan introduces the sound images and provides the rationale for why each image represents the sound that it does. However, sounds are learned best in the context of words and not in isolation. The Flipbook allows the child to hear and learn the sounds in words. Second, to allow the parent-teacher to model for the child the process of blending sounds into words. Audios are provided to assist the parent in learning the blending process and to permit the child to review the process on his or her own as often as he or she may wish. Third, to insure the child has the vocabulary to proceed independently in the reading program. If the two sounds the child is blending form a word that he or she does not know, the child has little hope of knowing if his or her blending is correct. The child learns to blend sounds into words using only words that are a part of his or her vocabulary. Two-Sound Flipbook Used in parallel with the Three-Sound Flipbook Teaches the child the sounds in the context of words Models for the child the blending of sounds into words Gives the child the necessary vocabulary for later activities

Who is the app for? CVi Connect is an iPad application intended to support parents, and teachers of the visually impaired (TVIs), who work with children who have Cortical Visual Impairment (CVI). The app can be used by parents, TVIs and anyone else who works with children who have CVI. CVi Connect's goal is to aid in the process of improving the visual impairment with this iPad application, and grow the awareness of CVI as a whole and provide educational content related to CVI. What does it do? The application guides the user through exercises of varying difficulty that are intended to help the child's eye focus on graphics on the screen, which stimulates the area of the brain that is most affected by CVI. By stimulating this area of the brain we can support the improvement of the child's vision. Over time the exercises are tailored to each child based on the data that is collected while the child and parent use the application. How does it work? Using the front-facing camera in the iPad the application can measure facts about how the child is responding to the exercises. All of these expertly-determined facts can then be graphed and analyzed by the educator, in whole or in part, across all training sessions. For example, it is possible to graph the time spent, on average, on training sessions combined with the number of times a sprite is touched, showing ways of measuring improvement in visual acuity as well as allowing a teacher to tailor future lesson plans to better match the needs of the student. In addition to analyzing favorite and least favorite lessons, the CVI system has the ability to use information from the training sessions to automatically generate new training sessions that are best for the student. As an example, the system can detect highly touched areas of the iPad and where sprites are commonly touched. Using this information, the system can automatically generate new lesson plans that focus the attention specifically on these areas as well as specifically AWAY from these areas to improve acuity. The system can use facts about the lengths of time spent on average by the user on training sessions to tailor the length of time a typical training session should take place. Where can I get help if I need it? CVi Connect maintains a support forum where users of the app (parents, TVI's and CVI professionals) are supported by leading CVI professionals and CVi Connect technical staff. Users can asks questions and provide feedback in this forum, which adds to the CVi community as a whole by serving as a place where CVI discussions can take place.
