Play the video in full screen to see what T is saying and Swyping to see how it is supporting his writing.
T doesn't know how to spell through and spelt it as thought but when he spells operation as operasion the app leads him to the correct spelling and gives him close choices should his Swping be less than accurate.
I also liked the way that he pauses to think of the word in chunks to better help him break down the writing process. The video helps us see his thinking processes as he is writing- making learning visible.
I notice that T is also pushing the space bar for spaces between words. The app knows where the spaces are as he takes his finger off the screen so he doesn't necessarily need to do that.
Matt has made the lower case keyboard with the Open Dyslexic font so as to better support learners who find differentiating letters tricky.
Just a note though that there is a bit of an iOS bug at the moment and you need to turn off guided access before you can install the new keyboards. I am sure it will be ironed out before too long.
