When giving presentations in the past before an audience, I used to get nervous. I think I can say that I have gotten over the anxiety of presenting before an audience, which is good since I plan on being a teacher. The longest presentation I have delivered in the past have ranged from seven minutes to about ten minutes. One issue that I have now is deciding how much information is too much. I tend to worry that I will not have enough information to give a lengthy presentation that I end up having too much information. Outlining helps but trying to figure out which pieces of information are important can be difficult. When I go to the speaking center, hopefully they will be able to help me with that. I have also used powerpoints as a way of sharing additional information, as well as pictures and charts for visuals too, depending on the nature of my presentation topic.
One skill that I have found to be particularly helpful (that I picked up from Spanish) is to try to visualize how you will give your presentation, as well as trying to remember key words or phrases (my Spanish professor made us give our orals before the class so she could record them so she could listen to them later). I also have found that having a video recording of a practice presentation is helpful because you get to see exactly how you appear giving the presentation. Also you have the opportunity to fix any distracting habits before giving the actual presentation. I try to eliminate any possibly distractions before coming to class, which actually helps quite a bit. Anything that will bother me while giving a presentation, such as loose jewelery or hair that is not pulled back, I try to make sure is not a problem before hand by either not wearing the accessory or putting clips in my hair.
