Top and First-Rate
Picking a top issue involves work: you cannot simply stand up and shout out on whatever pops into your mind? If you did that, it is unlikely you have worked out your material beforehand, and may soon face a baffled and, likely, hostile audience. Especially if the speech topic is a controversial one, e.g. the advisability of the U S A following the model of foreign policy that led it into Afghanistan and Iraq.
This simple art of public speaking law more or less covers the main difference between the two major types - information and persuasion.
My advice is this: Try to catch their attention early with an anecdote or happening that illustrates your point perfectly, and refer back to it often: this way, your audience will feel involved. Be personal, make a tie, and refer back in the different parts of the talk. Be aware that each of group member must be able to recognize the examples you are providing them. Read more about this in the educational chapters on this oustanding site you are now visiting. Jim has done a lot of work in cataloging all tips and tricks for students, and teachers like me.
Thus, one common theme you would have noticed, however, is that of the importance
of one?s idea topic. A top first-class is only top if it is of some urgency or importancy to the audience. If not, and you still want to rite a presentation about your subject; make
it important by tweaking some arguments in their "world".
