Anyway in my wanderings I came across this video which is a revelation to how I should write my essay! It talks about Kolb's Learning Cycle and I realised is the format for this professional diary as well: Write up your experience; reflect on your experience; draw on theory and consider the insights gained from your reflective experience and how this may be applied more broadly and then use activity to apply your knew knowledge to test out your theories and you've guessed it create new experiences ... and so the cycle continues!
I value the clarity of presentation and the use of a media which although not active can create an active approach in those that listen!
If I draw together my own experience of teaching and coaching then this experience, review, give some theory and breadth and then apply to a new situation is often used in the active teaching strategies or as an overview.
I am going to try to apply the systematic approach to writing some more of my essay now
