If you're interested in learning and education online I recommend these two.
The first, E-learning by Design by William Horton a highly practicle, hands on, solutions to e-learning problem x,y, or z. Informed, experienced, good advice with examples galore and links online.
The second, Educational Psychology something by someone you will come across repeatedly. As my background is not in formal teaching, but in TV production and the 'media' it is this kind of foundation that I need.
On reflection, I wonder if ahead of the MAODE a module on the Foundations of Learning would have been of value.
The 16 chapters of 'Rethining the Pedagogy of E-learning' edited by Rhona Sharpe would suit an MAODE student as several OU and other authors have contributed.
Do please get in touch if you have read or are reading any of the above. It is invaluable to share thougths, especially on Vygotsky.
