Hi Liz - I think you make a very interesting point about letting pupils be the experts when using technology. It's a big leap of faith for us as teachers to step back and allow pupils to explore - but by embracing the interests that pupils have in mobile and tablet technology we really can get them engaged in the classroom.
Hear hear- we've got to let kids run with it sometimes and just guide their path!
This is exactly what we need to be all aiming for as teachers; letting the pupils be the guides and architects of their own learning. That must be so liberating and motivating for you!
