The iBooks Author app enables the user to create multimedia material with static and dynamic images, voice threads, audio and text. I see numerous possibilities for it to be exploited because the learning potential and affordances it provides are endless and think it is a particularly interesting resource. However, the one principle drawback of the software is its limitation to Macs and iPads.
I have used iBooks author with learners by setting them a homework task to create a digital travel brochure. The students were highly motivated at the prospect of using technology as a tool to demonstrate their abilities in English, and the end results were impressive. I think there is also great potential to use the software to practice pronunciation by using the voice thread function and video.
