Simplex Spelling HD - Dolch Sight Words With Reverse Phonics, by Pyxwise Software Inc, is an app that has always gotten a lot of great press. We like to get the scoop on the developers behind the apps we review. This app was developed by a Canadian team, Craig, and Lisa Welburn, who have come to the app world with extensive experience in the field of technology. Craig has been in the software development industry, mostly involved in the video game venue, while Lisa taught university level courses in engineering and computer programming. It appears that a many an app has come along as the result of a young child, who inspires the task of building an app. Lisa became interested in literacy as she taught her children to read and write. Lisa's goal is to take academically challenging work and present it in a clear and concise manner. Simplex Spelling HD does just that, using the original 220 Dolch Sight Words. This app provides leveled lists for practicing spelling skills with complete ease. While there are some exceptions, the majority of our words are phonetically correct... Actually, somewhere around 84% of the time. Simplex Spelling enables the student to build each word phonetically using the built-in "reverse phonics" hint system - a term coined by the developers. Research studies have found that the best way to teach reading is through phonics and also that great spellers almost invariably make great readers. However great readers are not always good spellers. Reading Horizons Simplex Spelling's unique, immediate letter by letter feedback system is designed with clues and hints that will enable every student to spell each word successfully. It is a great tool to have for kids learning to spell and read, remedial students, those with dyslexia and special needs, or those learning English as a second language.
