Preparedness is always very important. When a presenter is not prepared it shows and this can make a very bad presentation and not a good impression. It is also important to make sure the presenter is well groomed and dressed nicely as well. Remember, ask the audience if they have any questions at the conclusion of the presentation.
You've received some great suggestions. Another one that I've found important is to *always have a backup plan.* I've arrived to present only to find that the projector is not compatible with my computer...or the Powerpoint has a glitch...or the time I was originally given does not match what I'm given in reality. I find that it's necessary to know my material so well that I can "wing it," totally changing content as necessary to fit whatever surprises come my way.
Know your topic! Don't ever appear to just "read" your slides or notes. Make eye contact, and above all, think of possible questions your audience might have for you...anticipate them before the presentation and have an answer ready to go. Good Luck!
It's been said above, but I emphasize this to all of my students, practice, practice, practice - 5 - 7 times before you give your speech. This makes you more confident, reduces stutters and "um"s, and helps you to slow down (speaking too quickly is common with nervous speakers).
The advise I give to most people who are preparing to give a presentation is "relax." It is very common for people to feel nervous when speaking in public. The best way to combat this feeling is to be prepared. A prepared speaker leads to a confident speaker.
You also need to be well organized. Have everything that you need ready and in the right order. This way you won't be shuffling through papers while you are in the middle of your speech.
Also, don't forget to practice your speech. You can practice in front of a mirror, a friend, parent, etc. When you are giving your speech keep your head up high and try to maintain eye contact with your audience. Also, refrain fro using slang such as "um" or "like."
Being a good speaker takes practice so be patient. Practice makes perfect!
These are pointers given to me during defense of dissertation:
1. Address the right audience. In other words, do not speak with a language that is stuffy, complex, or personable and simplistic unless you first identify your audience.
2. Make sure your font is over 36pt, always bullets, no paragraphs unless they are short
3. Do not use distractors such as Clip Art unless it is directly related to the presentation.
4. Always keep the title of the presentation atop each of the slides.
5. When presenting Data, make sure you triangulate it, break it down, and analyze it in separate sheets, placing the graph next to each of the analytical points.
6. Talk slow, and have a timer for each new topic. Have someone from the audience guide you or move your slides at the time you both agree. give at least 30 seconds for the slide and the information to filter through.
7. Don't forget the natural flow of the presentation. One slide should be a continuation of the one previous. Do not jump around.
8. Always keep a "parking lot" on the back. If anyone has observations or questions, they can write them on a sticky note and place it on a large piece of paper which you will title "Parking LOT" and tell everyone that all their questions/comments should go there and you will address them at the end.Tell them to specify which slide they referred to.
9. During your Q and A you will move to the parking lot to read out questions and comments.
10. Always allow for a 7-10 minute break in a presentation lasting longer than 55 mins to one hour.
**You might do an ice breaker showing the reason behind the presentation, and even offer a piece of gum (good to stimulate thinking) or candy for a start.
Hope this helps a bit!
The way your question is phrased, it sounds as though you are looking for a particular answer, but there are many precautions that one should take when making a presentation.
The first one that comes to my mind is that a presenter must always be prepared to make a presentation with no technology whatsoever. You might have a wonderful PowerPoint, film clips, music, or some other way in which you need technology to make your presentation. But technology can fail you, and the show must go on. The computer may not work, the overhead projector might have a bulb out, or you might have lost your flash drive. I have always prepared a set of brief notes from which I can speak, just in case!
Along the same lines, I take precautions about any presentation materials that I plan to use. I have what I need on a flashdrive and I email what I need to myself as an attachment. That way, if I do have a technological means of delivery, I have a backup of my materials.
Another precaution is preparation. I know my content thoroughly, and if I do not, I have no business making a presentation at all. This means that I am able to speak intelligently with just a brief outline or a few notes and answer most questions on my topic. It is not simply a question of memorizing material; it is a question of really knowing the material.
There might be other precautions that should be taken when giving a presentation, but these are what come first to my mind. If you are called upon to give a preparation, be prepared and do not count on technology. Good luck!
Precautions like always be on time, be prepared, do not read your presentation, and highlight and reinforce ideas are common to most presentations. Try to use visuals as much as possible. Always be positive and look warm and congenial.
First, I need to share one of my real-life experiences. In our class in the university, once, one student was very well-prepared for her presentation, she came collecting enough data, reading the researches she went through, studying well. But what she forgot probably, is to check whether the projector works soundly or not. And, surely, you can assume what could have happened on the day she was going to give her classroom presentation in front of at least 50 students. She could not show her data & slides, she had to give solely an oral presentation. In fact, the expenses the slides took to be made, all were wasted, and marks were deducted a bit (since she could be able to give a very good presentation). But the student got very scared and nervous when she saw that the machine was not working, and the nervousness had a great impact on the presentation. Later, she said that, she could have presented far better if she would not have done such mistake.
So, it would be a suggestion that, how much well prepared you are for your presentation, don't forget to check all the technical supports which you are going to use. That will also be a part of the precautions as you said.
