dialogic teaching

This is just an over excited note --- must think more about it, any comments would help please!

Have been wondering how to get the idea of dialogic teaching ino Key Stage 4 Maths lessons (ages 14-16). I have started to use video podcasts made by the students and also collaborative documenst on our school VLE. How could I begin to develop extended dialogue between students? Maybe I need to start with me and one student --- BUT what are the other students doing whilst this is happening? They need a directed task.

Enter @KnikiDavies on Twitter and her blog post http://thinkteaching.wordpress.com/2010/10/01/maths-groups-enriching-learning/

She outlines the following roles for students:
Facilitator – makes sure everyone is on task. Keeps things moving.

Understanding co-ordinator – checks everyone understands what is going on. Asks questions to make sure everyone is clear about the methods used.

Resource manager – responsible for fetching equipment and asking questions of the teacher. Nothing is provided to the children – if they think they need whiteboards, calculators, compasses, cubes, they have to get them!

Reporter/Recorder - keeps track of the group’s thinking and working out and feeds back at the end.

Yes, definitely some ideas for me here...... thanks Mrs Davies!
