About

Minimal Pairs

This app helps children aged 3-5 with speech intelligibility issues discriminate between words that differ by a single sound. It uses a phonological approach with a "cycle" method, focusing on specific speech patterns. Children can "Show Me" target words by tapping pictures and record their own speech for playback.

Highlights
  • Auditory discrimination of minimal pairs
  • Phonological approach (Hodson & Paden)
  • Cycle method for targeting patterns
  • Record and playback speech
  • Multiple scoring methods for clinicians
  • Focus on Final Consonants, Initial Consonants, Initial /S/ Clusters

Minimal Pairs is an auditory discrimination activity that helps children discriminate between words that differ in pronunciation by one sound. They learn to hear the difference between words like “stop - top” and “rake - wake”. They are prompted to “Show Me” the target word by tapping on the colorful pictures and listening for the sounds in the target word and a foil. This app uses a phonological approach to remediating speech that is based on the ideas of Hodson and Paden. The program focuses on target patterns rather than target phonemes. One pattern is targeted for a limited time, two to four weeks, then the next pattern is targeted. Hodson and Paden called this method of introducing patterns a “cycle”. A clear speech model is presented for the child to imitate and they can record and play back their own speech. The clinician can choose from three scoring methods. 1. Score each response as correct, distorted or incorrect. 2. Score responses as correct, distorted, substituted, or omitted. 3. Score productions based on whether they are spontaneously correct/incorrect or imitatively correct/incorrect. This app focuses on Final Consonants, Initial Consonants, and Initial /S/ Clusters. Appropriate for children ages 3-5 with impaired speech intelligibility. This app uses the content from the Minimal Pairs game from LocuTour’s Phonology CD.

Scientifically validated as a highly effective approach to improving spelling skills. 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. Simplex Spelling is one of the best ways to improve English spelling and reading skills. Using a powerful combination of phonics lessons, spelling/word patterns, syllabication, our unique “reverse phonics” (phonics encoding) approach and contextually relevant spelling rules. - "Simplex Spelling has a feedback method that rivals anything a teacher can do in the classroom. " - Carolina Nugent, Director of Education KinderTown. - "No other literacy apps are this comprehensive." - Teachers With Apps - "WOW!!!! I found my miracle app" - Speech Language Neighborhood - Academics' Choice Award 

Teaching over a year of spelling curriculum with more than 650 high frequency words divided into 54 lists that are organized by spelling patterns and difficulty levels. Each of the 54 lists comes with a lesson that teaches one of the basic building blocks of spelling in the English language. These basic building blocks include syllables, sounds, spelling rules and some of the more advanced English phonograms. 

 Students learn a new concept for each lesson building on the skills learned from previous lessons and those covered in Simplex Spelling Phonics 1. Simplex Spelling Phonics 2 guides the student and acts as a personal spelling coach with every word, while teaching students "how to spell" English words. Our “reverse phonics” hint feature breaks each word down into individual phonemes to improve phonemic awareness, a critical skill in achieving literacy. One of the main areas of focus in Simplex Spelling Phonics 2 is on syllables and how they affect the way we speak, read and spell. Every word is broken down into its syllables both visually and auditorily to help students build phonological awareness skills. Many lessons teach the concepts of open and closed syllables, compound words, the rules governing vowels in syllables and syllable stresses. The stress on each syllable is subtly conveyed with every word to help students understand how the stress on a syllable affects the way words are pronounced and spelled. The schwa sound and its occurrence in English words is also taught.
