We are just getting started with the online presentation by Fei-Yu Chung who will be talking about "Exploring the use of mobile phones for grammar learning". A very interesting presentation resulting in a preliminary finding that students seem to learn better in computer-based environment than with mobile devices. One reason for this is that they didn't tend to the given assignments always that seriously.
I think the message from that is that the pedagogy needs to be seriously re-thought. Bridging the gap between informal and formal learning is not done by just using the tools the learners use in their freetime. Instead, we really have to come up with pedagogical designs that are engaging and motivating and not just mobile and movable.
