Putting pedagogy into Technology Enhanced Learning (TEL)

I am expanding my focus from removing the infrastructure barrier(s) (real and perceived) to TEL onto exploring how pedagogy can be used in this digital age. The title of the essay I am writing is: Beyond the computer screen:Enhancing differentiation through the merging of electronic and human interfaces

The essay focus on how a tutor working face-to-face with a learner in an individual tutorial in the 'real' world can be replicated at a distance through the use of Technology Enhanced Learning (TEL). The 'quiz' is the vehicle used to identify the learners' understanding of a particular topic and the one-to-one tutorial is the methodology used to ensure all feedback from the quiz is understood and that misunderstanding are rectified to enable the learner to succeed.
