Using Show Me app and Twitter to feed back to students

If you've not come across the 'Show Me' app before, it basically allows you to photograph something and annotate it, at the same time recording an audio commentary on your iPad. Then it can be accessed by others via the internet.

Likes:

It's free (obviously not if you have to buy an iPad first!).
You can photograph specific bits of texts to highlight learning objectives.
The stylus helps you identify specific details clearly.
It is a fun way to mark (very important after 13 years in education!).
You can 'flip' the learning so students view their feedback outside of lesson time and come ready to discuss it.
They can rewind / replay it as many times as they like/ need to.
You've got it for next year.
You can share it with other classes.
Students can use it themselves to feed back to each other.
It has other uses including image analysis, annotating texts, modelling and drafting.
Its novelty value creates interest.
Potentially useful for cover lessons.

Dislikes:

The photos aren't always clear and the iPad camera doesn't have a flash.
Even the best stylus looks like crayon on screen.
It's really hard to talk and write at the same time!
Students can't immediately ask questions if they need to.
You can't edit it very easily, so you need to get it right first time.

Despite the stumbling in places, I thought I'd risk sharing this in the hope that it proves useful to someone. It is essay feedback on Y12 Language and Literature Unit 1 'Food Glorious Food'.

Please don't crucify me for my first attempt!

I posted a link to this for students on Twitter (a separate account just for revising this unit). Homework was to watch it and comment on it next lesson. I also posted links to pages on writers in the anthology, the Examiner's Report from last year and a link to revision websites. The students have also started to suggest links themselves. Hopefully their contributions will grow. Early days, but it has already engaged some of my more reluctant learners! So it looks promising.
