m8 the first weekend they teach you how to create a lesson plan and show you how to take a lesson then you go away and put into practise what you have been tought by creating a lesson before your 2nd weekend so dont worry about it you do 1 practical and 1 theory lesson the practical is on anything you want such as packing a bergan or taking a shit!! what ever you want but your theory has to be military related I would say pick somethings such as how to maintain your uniform or bulling your boots something long and easy to stretch out hope this helps bud.
You have to do two lessons, one theory and one practical or "EDIP" as they call it. Its not hard and you dont need a lesson plan now, the whole point of the course is to teach you how to make one.
I did my EDIP on putting a rifle sling on, others did knot tying, filling in an ATUD and so on.
Since the course I have never used the dits format, I only did it as a prerequisite to other courses.
A girl from my Sqn did 'making cocktails' and choose 'Sex on the Beach' and 'Morning Glory'.
Another nursey type did how to 'self check for testicular cancer' and she used eggs in a hankie as training aids.
I did mine about the same time (2000) and someone taught us how to build a car-bomb.
I enjoyed the course. Choose a simple subject that will fit the DITs format nicely. Building a paper aeroplane is good. I did that for my NHS teaching course. I called the aeroplane design 'the Growler 2000'. I was then able to tell the nurses that symmetry was all important in a good Growler, and that gripping your Growler too hard would end up in disaster!! I got endless fun out of that! Only about a third of the class were native British speakers but the rest were still keen to discuss all manner of Growler related issues!
