A structure for oral presentations:
I Introduction (Attention-getting opener: e.g. a question, a statistic, a quotation, an anecdote)
Tell what you are going to deal with:
1 Who or what
2 Why and how
3 What you want/intend to say
II The substance of the presentation
Present arguments or evidence supporting your aim/intention (use examples):
1 To inform – give evidence/examples
2 To persuade – give arguments/explanations
3 To entertain – choose amusing information or arguments and/or an entertaining manner of presenting them
Sum up or conclude with personal opinion, analysis.
Six signals all audiences want:
1 I will not waste your time.
2 I know who you are.
3 I am well organized.
4 I know my subject.
5 Here is the most important part.
6 I am finished.
