Padlet

This tool enables you to visualise student feedback instantly. Padlet, which can be accessed through
http://padlet.com
is a tool that can do just this. Pupils can respond to a question that you have set up either during the lesson or for homework and share their thinking on this. This is a quick AFL check of learning, or a way to collect opinion.
We also have several sets of activexpression voting devices in school which also allow the text in facility.
Do remember that you can book almost a class set of tablets with internet access from the IT department. This means you could use the above in your lesson. Contact the IT team for more information on this.
