The first step in creating your outline is to determine what main ideas you will include in your speech. Most students find that that they can clearly explain no more than three or four main ideas in a four- to six-minute speech. Your presentation will be stronger if you choose to explain a few ideas clearly and comprehensively rather than choosing to explain too many ideas sparingly. Your main ideas are represented on your outline by Roman numerals (I, II, III, etc.) as shown in the following example.
- The link between lung cancer and smoking
- Treatment options for lung cancer patients
- The mortality rate for lung cancer
Obviously, the outline shown above is incomplete. There is more to an outline than the main ideas. Where are the supporting details -the facts and statistics, the stories of patients who have experienced lung cancer and survived? Any reader should be able to deduce from your outline how you intend to present the topic and how your supporting details relate to your main points. You have two or three main points, but which details fit where? Merkley and Jeffries suggest the utilization of a graphic organizer to help you visualize how your details support your points (350-59). A network tree organizer, such as the one shown below, is useful when you intend to list facts, definitions, or examples that relate to a single idea or concept -in our case, points relating to one main idea.
If you have a main idea, but you cannot find at least two (or three) supporting details for that idea, you probably need to reconsider whether that particular point is integral to your topic. If it’s a key point in your presentation, you should be able to “back it up ” with several relevant facts or explanations.
Supporting details should be listed vertically under each of the corresponding main points and are represented on your outline by capital letters (A, B, C, etc.). Supporting details should be indented on the outline; the indentation acts as a visual reminder that these are lesser details linked to the bigger idea above them. The following list is an example.
The link between lung cancer and smoking*
A. Smokers are seventy percent more likely to develop lung cancer
B. Scientists can show that nicotine and other cigarette additives destroy lung tissue and air sacs, reducing the lung’s ability to defend against invading cells
The addition of sub-points (A, B, C) under each main idea (I, II, III) helps to further explain and validate the bigger main idea. However, in most cases, your outline will need to go one step further. What if you need to further explain some of your sub-points? In the previous example, subpoint A provides a statistical detail (seventy percent of smokers are more likely to develop lung cancer). It would be important to list the source of this data and perhaps the timeframe for this statistic so that your listeners can assess the validity of your facts. These details should then be listed vertically under subpoint A, as they relate directly to that single statistic and to that particular sub-point. These details would also be further indented to show the corresponding relationship and are represented by numbers (1, 2, 3, etc.). Take a look at the following example.
I. The link between lung cancer and smoking
A. Smokers are seventy percent more likely to develop lung cancer
- Five-year study published in the Harvard Journal of Medicine
- Study compared medical records of 10,000 lung cancer patients
Now let’s put the entire outline together so that you can see the finished project.
I. The link between lung cancer and smoking
A. Smokers are seventy percent more likely to develop lung cancer
- Five-year study published in the Harvard Journal of Medicine
2. Study compared medical records of 10,000 lung cancer patients
B. Scientists can show that nicotine and other cigarette additives destroy lung tissue and air sacs, reducing the lung’s ability to defend against invading cells
II. Treatment options for lung cancer patients
A. Partial removal of affected lung tissue
B. Lung transplant
C. Radiation to shrink existing cells
- Palliative measure only
- Adds +/- two years to patient’s life
III. The mortality rate for lung cancer
A. Less than forty percent of lung cancer patients survive more than three years
B. Lung transplants result in organ rejection (and ultimately, death) in fifty-eight percent of patients
