Oral presentation

I meet this excercise on the Jam blog.It is imprtant to study this web site before doing the presentation.In the following i am going to write a summery of that.
Preparation involves 3 steps:
1-Research
2-Plan and organise
3-Write and edit.
We have done the first stage already.For second and third stage making a plan and the organise it's order is so important then write and edit what we have to say.
The following steps are useful to develop a clear plan for our talk:
-Brainstorm the topic to clarify what you know
-Organise the material logically, eg. chronologically, spatially (diagrams and maps), sequentially (first, second)
-Develop a plan or structure.
Structuring a presentation :
tell them what you are going to tell them (introduction) .
tell them (body) .
tell them what you have told them (conclusion).

Afterword practise and rehears .... .For example practise in front of mirror or in front of friends would help us to be more confidence and ready in real presentation.At the end using presentation techniques.
