Speaking in public is probably the most stressful thing most students will have to do.  For most of my English students, they not only have to deal with the stress that public speaking brings, they also have to deal with the language barrier when trying to communicate.  In my public speaking classes, I stress "preparation" as the key to overcoming not only the fear of public speaking, but also in overcoming the language problems they might encounter during the presentation.  I believe, to give a good presentation, the speaker must first learn the basics of public speaking.  Public speaking is a "skill', an "art", and can be learned.  Herein, you will find links to websites providing tutorials on different aspects of public speaking. I hope you find them helpful and provide you the tools you need in making your presentation. Good luck!
