Honestly, giving presentations in front of the class is really not my cup of tea. I am not the most outgoing person for one, and don’t get me wrong I do like to get my point across. I just feel more comfortable when it is a group effort, and I am not single handidly doing everything by myself.
Key Elements in a speech ; poise, confidence, sentence fluency, personal touch
When you give a speech about something you enjoy you get into it. You really understand what you are saying, and you are not just saying a bunch of nonsense. When you give a speech about something you are not to favored upon the mood will probally keep the audience yawning, and you will want to leave so badly that everything you said will get through to no one.
Powerpoint is helpful obviously because it is an advancement in technollogy. And, it can make a presentation that much better.
Maybe, in college when presenting amongst my pears. Or, at a job interview, meeting, etc.
