Week 2: How to convey your message: choosing the right topic sentence Each individual section of a presentation, such as a description of one experiment, has a specific message that you wish to convey. This week we will discuss strategies to maximize the audience's appreciation of this message. Obviously a logical flow is necessary, but even more important is to set a framework of the section by starting with an appropriate “topic sentence”. The best choice for a topic sentence is a statement related to the conclusion of that section. This statement can be conclusion itself, but it need not be; something that creates an “expectation of the conclusion” will nicely prepare the audience for the material to follow. With a well-constructed topic sentence you can control how the audience listens and perceives that section, and guide them to understand the presented material as you wish them to.
