The KC children liked the alphabet video so much that they asked me to tweet the link in case other children were learning about letters. Another Kindergarten class on the other side of the world tweeted back to say that they really liked the video because that's just what they were learning about! The KC children tweeted back to ask them if they had any other good ideas for learning letters. We are waiting for their reply.
This is a delightful example, initiated and followed up by students, of how class learning networks can support learning.
