Sam Green is a PhD researcher in the Department of Linguistics at University College London, UK. I hold an MA in Linguistics & English Language from the University of Edinburgh and an MRes in Speech, Language, & Cognition from University College London. My research into how children learn speech sounds is funded by the Economic and Social Research Council. I have worked as a Teaching Assistant in my department, and at the Linguistics department at Queen Mary University London, for two years now. My interest in Peer learning using technology/the internet developed as a result of discovering PeerWise and implementing the use of this as a for-credit part of a module on which I was a Teaching Assistant.
