I just downloaded iWordQ app. I've been a big fan of WordQ for years and was happy to see the app. Although it is a bit steep at $25 it is worth it for those who need sophisticated word prediction.
Check out free online thinking tools/graphic organizers. Also explore the Online Interactive Resources. These are text heavy/dependent resources so consider how you can make them accessible to all learners. For example, use word prediction support, recreate them in a tool such as Inspiration that allows learners to add ideas in pictures, words and recordings. Or recreate the graphic organizer in another format such as an interactive whiteboard application - build in supports for success.
Interesting article. I'm not so sure that Ian Jukes, quoted liberally throughout the article, would be a big fan of RTI but I could be wrong. "Drill and kill" has been around a long time. Whether this transfers to higher level thinking is debatable. Simply providing apps that replicate drill activities we do on paper won't, in my opinion, capture students used to video game quality action - at least not for very long. The reality is classroom time is limited. If we drill students this time has to be taken from somewhere - inevitably it comes from the "real" learning time. My greatest fear of mobile technology is that it will become modern day "flash cards'. If we are going to use mobile technology, let's use it to build in support (within an exciting cross-curricular, inquiry-based classroom) such as screen readers/word prediction, and use it to provide access to apps that help students analyze, synthesize, evaluate, collaborate and create - real 21zt century fluencies. http://www.committedsardine.com/fluencies.cfm
