The Early Literacy Skills Builder app incorporates systematic instruction to teach both print and phonemic awareness. ELSB is a multi-year program with seven distinct levels and ongoing assessments so students progress at their own pace. Note: This free version comes with level 1 - Lesson 1 and Level 5 - lesson 1. Full levels can be purchased from the in-app store. Five years of solid research have been completed through the University of North Carolina at Charlotte, proving ELSB to be a highly effective literacy program and more effective than a sight-word only program. ELSB is based upon the principles of systematic and direct instruction. It incorporates scripted lessons, least-prompt strategies, teachable objectives, built-in lesson repetition, and ongoing assessments. The seven ELSB levels contain five structured lessons each. All students begin at Level 1. Instruction is one-on-one or in small groups. Teach scripted lessons daily in two 30-minute sessions. On the completion of each level, formal assessments are given. ELSB includes everything you need to implement a multi-year literacy curriculum.

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.
