Things to Think About When Giving an Informative Speech

Narrow Your Topic

It is better to talk in detail about a smaller aspect than to try to tell everything. For example, I once had a student try to teach us how to build a computer in seven minutes. There were many technical terms and we were overwhelmed. The next week, a student showed up how to replace one component in a computer.  I went home and tried it, and because he explained it clearly, I could do it.  Speech coach, Dale Ware says, “Too many people try to put too much information in one presentation, a big mistake; keep it simple.”

Define Terms

I attended a community lecture on wild edible plants in the Ozarks. The speaker said, “This plant has a cathartic effect” and “I like this for its astringent properties.” I thought I knew what these terms might mean but I wasn’t sure so I looked them up while he was talking. At least I had one of them right. The point is that I missed part of his lecture when I was looking up unclear terms.

Make it Personal

“I want to talk to you today about” is much more personal than saying, “I will explain how”

Use Stories When Possible

When possible, work stories into your speech. Make it personal by telling stories about how the topic relates to you.

There is an entire chapter on stories.
