A PhD thesis on the tutor-web

One of the main tutor-web proponents, Dr Anna Helga Jonsdottir, defended her PhD thesis on April 17, 2015. The work underlying the thesis was largely based on experiments using the tutor-web.  A copy of the PhD thesis is available at http://bit.ly/PhD-AHJ and the thesis also provides the single most comprehensive description of the tutor-web.
