Back in the day I recall using a mnemonic for the things that you needed to include in your INTRO to a lesson or lecture. The mnemonic was I.N.T.R.O Interest. (I.E get the class's interest) Need to know. (explain why they need to know what you are going to teach them) T....... (Can't remember!) Revision. (briefly revise previous lessons with the class to make sure they were up to speed) Objective (Describe what they should have learned by the end of the lesson. Can anyone remind me what the "T" stood for? I've completely forgotten!
