how to give an effective presentations
The structure of a presentation
It usually includes 3 parts.They’re introduction,body and ending.
1.Introduction Firstly please stimulate interest and establish a relationship with your audience; get the audience’s attention like ‘Good morning everyone…’.Secondly give the audience a clear idea of what you will be talking about; it should be short and simple.For example ‘This morning I’m going to talk about…’ Thirdly please tell your audience your outline,what to expect,how you will proceed; briefly name the parts of your talk; use words such as ‘first’ ,‘then’,‘following that’,‘after that’,‘finally’.
2.Body Moving from the Introduction to the Body,you need a transition signal such as ‘Okay…’‘Let me begin…’; show a visual aid; pause or move.Then present the content following the sequence presented in the outline; develop the topic in a logical way; move clearly from one point to the next; support what you say with examples or evidence.
Beginning ‘I’d like to begin by…’,‘Moving on now…’‘Firstly,…’
New points ‘the next point I’d like to focus on…’,‘Moving to the next point…’,‘Another important aspect is…’
Expanding ‘To expand on this point…’‘In other words…’
Examples ‘AN example of this is…’‘Let me illustrate this by…’
3.Ending Moving from the Body to the Ending,you also need a transition signal such as,‘Finishing up now…’‘Now,to conclude…’
Please summarize the key points in the same order as in the outline; help your audience understand what are the main points you are making; do not add new material; use mostly past tense with signal words ‘First I looked at…’,‘After that I…’,‘Finally I…’Then you should make a simple,brief statement so the audience knows you have finished.‘Thank you all for listening…’‘I’d be happy to answer any questions…’‘If there’s anything you would like to ask…’and so on.
