Co:Writer® Universal app and third-party keyboard gives students easy access to word prediction on iPad, iPad Pro, iPhone, and iPod Touch. Students simply sign in to their Co:Writer Universal accounts to write with their personal settings and vocabulary. ABOUT CO:WRITER UNIVERSAL This version is for schools with a Co:Writer Universal license only. Users without a Co:Writer Universal license must purchase the Co:Writer app. HOW DOES CO:WRITER WORK? As letters are typed, Co:Writer predicts the intended word with a selection of word suggestions using powerful grammar-smart word prediction. These suggestions can be read aloud with a swipe. Selecting the intended word places it into the writing document. For feedback while writing (and after writing) built-in text to speech can be used to read letters, words, sentences, and the entire document. 4+ MILLION TOPIC-SPECIFIC DICTIONARIES Co:Writer has access to a main prediction dictionary (that includes core words) and Topic Dictionaries (that includes topic specific words). Co:Writer can access over 4 million topic-specific dictionaries which are activated based on the writing task. A small sampling of the variety of topic dictionaries: - America's Cup - Apple II - Compare and Contrast - Dinosaurs - Grumpy Cat - History of the Peloponnesian War - Mahatma Gandhi - My Dog - Pig Latin - Rolls-Royce Silver Ghost - SpongeBob SquarePants - Tommy (album) - Wonders of the World SPELLING SUPPORT Co:Writer handles the widest range of spelling mistakes through its Flexspell™technology including phonetic spelling and inventive spelling errors (letter omissions, word ending omissions, letter reversals, etc). Examples of how Co:Writer aides with phonetic and/or inventive spelling: Before Co:Writer The blk jargon flu over the bra lfnt. R u hpy to ce me? I no hw to nor the fone. After Co:Writer The black dragon flew over the gray elephant. Are you happy to see me? I know how to answer the phone. GRAMMAR SUPPORT Co:Writer bases its prediction off of proper grammar, and uses its understanding of grammar to accurately predict words within the framework of valid sentence structures. Examples of how Co:Writer aides with grammar: Dogs are furry. (noun, verb, adj.) - When you typed d-o, you get plural noun choices Three very mangy dogs ran down the street. (adj., adv., adj., noun, verb… etc.) - After typing three, very, mangy, you get plural noun choices, then you get plural verb tenses. OTHER FEATURES - Built-in Text to Speech - Export

About

  • Tactile graphic design files available for download
Read full description

CodeQuest is an interactive game designed to teach coding logic to preschool and early elementary students. Students learn new skills as they navigate a series of grids that increase in difficulty as the game progresses. CodeQuest was created for use by blind, visually impaired, and sighted students alike, making it ideal for use by an entire class! CodeQuest is easy to learn. Players help an astronaut return to his ship by devising a series of commands to guide him. The solution with the least number of steps earns the highest possible score. The grids get increasingly complex as the game progresses. This allows for the introduction of concepts like sequencing and looping. In addition to all the game fun and coding concepts, students also benefit from the computational thinking used throughout CodeQuest. This includes the ability to: develop a solution to a problem; to recognize patterns and trends; and to identify the best among multiple possible solutions to a problem. Tactile graphic design files of the grids are available for download. Go to www.aph.org and search “CodeQuest” to find them. You will also find design files of three tactile grid boards and several manipulatives including the astronaut, rocket ship, alien, and arrow tiles that can be laser-cut or 3D-printed. Features: * Fun and easy to use for young students. * Fully compatible with VoiceOver. * Integrates fundamental coding concepts such as sequencing and looping into game play. * Allows students to work on orientation concepts including up, down, left, and right. * Motivates students to practice problem solving, planning, and computational thinking skills. * Great for visually impaired students to learn access technology through game play. * Great for blind students to practice tactile graphic reading skills.

Verdict

The call

The clearest difference is review sentiment: CodeQuest at 83% against Co's 8%. CodeQuest also leads on rating (4.7 vs 2.6) and ratings volume (96 vs 17). Co's advantage is update cadence (every 4 months vs every 17 months). On price, ads, in-app purchases and monetization model there is nothing between them.
