Scientifically validated as a highly effective approach to improving spelling skills through our phonics approach. A published study revealed that students demonstrated an average spelling improvement of 1.9 grades among children in a classroom setting who regularly used Simplex Spelling over a 18 week period. The largest student improvement observed over the same time period was 4.4 grade levels as assessed by administering the Schonell Spelling Test. Linda Chmiliar, "Improving the Spelling Skills of Students with Learning Disabilities using Apps on the iPad", International Journal of Technology and Inclusive Education, pp. 962-971. Special Issue Volume 3, 2016. Simplex Spelling Phonics 1 teaches a full year of spelling curriculum with over 450 high frequency words divided into 42 lists that are organized by spelling patterns and difficulty levels. Each of the 42 lists comes with a lesson that teaches one of the basic building blocks of spelling in the English language. These basic building blocks include the different phonograms, sounds, and spelling rules. Our spelling lists focus on some of the highest frequency words in the English language to help students establish a base foundation of literacy and confidence with spelling and reading. Students learn a new concept for each lesson building on the skills learned from previous lessons. Simplex Spelling Phonics 1 guides the student and acts as a personal spelling coach with every word, while teaching "how to spell" English words. Memorization may be sufficient to pass a spelling test, but it often does not transfer into good long term reading and spelling skills. Our goal with Simplex Spelling Phonics 1 is to not only teach a list of words, but to teach students “how to spell” these words, thus building long term skills that can be used for over 84% of the words in the English language that follow phonetic patterns. Many studies show that students who learn to read through phonics have a higher level of literacy than students who learn to read by using flash cards and the whole word approach. Also, that not all readers are good spellers, but almost all good spellers are also good readers. This is why Simplex Spelling's comprehensive unique phonics approach to spelling really works to create both better spellers and better readers. Note: Now supports both North American and British accents.
