Are the instructions, directions, descriptions and explanations clear, concise and coherent?
Has the speaker:
planned what is going to be said?
stated the outline structure of the exposition? ('advance organisers' eg: ‘We are going to find out...’).
selected the key points: identified and made explicit the relevance of each and their relationship to each other? (‘There are four things we need to think about ... because ...’)
sequenced key points appropriately?
used short, simple sentences: explained specialist vocabulary if it needs to be used, given concrete examples or asked the listeners to generate their own?
signalled when a new point is made? (‘Now let's look at...’ ‘The third thing to look out for is...’)
summarised key points (or got the listeners to summarise)?
sought feedback to check understanding (at each point if necessary)?
