Here is a list made by British students in answer to the same question. How many of them did you include in your list?

First of all, the speaker introduced their presentation and gave a brief overview of its content.
The speaker made sure people understood the important points by summarising them later.
The presentation had a good beginning, clear sections, and the end was signalled.
The speaker used visual aids (PowerPoint slides or transparencies).
The visual aids were interesting, did not contain too much information and the text was large enough to read.
The speaker didn't sit down but moved about a bit and looked at the audience.
The speaker used a clear voice, spoke loudly enough and spoke at a good speed.
The speaker seemed confident and had probably rehearsed it beforehand.

Tarek uses all of the following good presentation techniques:

Introduces the topic at the start of his presentation
Interacts with his audience
Makes eye contact with his audience
Stands, and uses hand movements to help deliver the presentation
Indicates what will follow later in his presentation
Has interesting slides with clear and brief content
Refers to specific slides in his presentation
Indicates that his presentation is coming to an end
Ends his presentation and invites questions

How did his use of these techniques help his presentation?

Tarek does not read his presentation aloud. Reading a presentation aloud is not recommended. It is much better to use your PowerPoint slides or a few notes to guide yourself as you speak. Your presentation will be more effective and more easily understood by your audience if it delivered naturally.

Here are the techniques correctly matched with their uses:

Make sure your presentation has an introduction, recognisable sections, and a clear end.
A clear structure will help the audience to understand better.

Use visual aids (PowerPoint slides or transparencies) to highlight the main points.
Information that can be seen helps your audience's understanding of what they hear.

Reinforce important points by summarising them at the end of a section.
This ensures the audience grasp the essential points that you want to communicate.

Check that visual aids do not have too much information and can be read easily.
Visual aids need to be read easily and quickly while listening.

Try to project your voice, speaking loudly enough to be heard.
Voice control is important for your audience to be able to follow you.

Stand to deliver your presentation and try to use eye contact.
It will help engage your audience in the topic if you are both clearly visible and looking at them.

Have a 'live' rehearsal beforehand with a friend acting as the audience.
This helps ensure that you can keep to time and will help you develop confidence.

Using techniques like these will help you give a more effective oral presentation if you are asked to give one during your course. You may be asked to give a joint presentation with another student, in which case you will need to organise carefully who does what.
