CATA 101 - McGaan

Narrow your topic (eventually) to what could be handled in a 12-20 page term paper. In any one speech 2-4 main points is all you can do effectively.
Each speech will need a specific topic, a thesis and a specific purpose - ideally each of your speeches will build on the previous one.
REMEMBER: you are not required to cover everything about your subject -- even everything about your narrowed topic. You can't give a good speech and cover a great deal of information. Doing a good job on a limited set of points is far better than doing a superficial job on a broader topic!!!
Consider the audience. You want to tell us NEWS about your issue while not going over our heads.

You don't have to follow this structure, but see me if you have another idea.
The goal of the first speech is to explain the current state of knowledge regarding your topic. In essence you will TEACH the class material about human communication in a way that is clear and will help them remember the material of exams and for use in their lives.
Some ways to do that:

The goal of the second speech is to lay out the principal arguments and problems regarding your topic that are currently being discussed as important.
You want us to understand the nature of the controversy but you don't want to persuade us that one side is right.
Some ways to do that:

The goal of the third speech is to present a plan of action that solves some problem related to your AND persuade us it should be adopted

You will have some latitude in this speech to select an audience different from (and more suitable for your purpose than) CATA 101.
Some ways to do that: -- to be covered later (see text for ideas)
