How to develop an oral presentation You have one chance to make a point.

Reference tive.html tive.html “The standards for public speaking in science and academia are relatively low, so a good presentation often is memorable”.

What is an oral presentation? It is a condensed version of the paper. It is organized around one TOPIC. A TOPIC is a clear statement of a problem. It has logic (a string of topics), little text, and clear graphics. It tells a story with graphs, tables and pictures.

An oral presentation Follows the IMRAD convention: Introduction, Materials and Methods, Results and Discussion Tells a story. Its characters act along string of topics linked together from beginning to end.

Planning What is expected of the presentation? informal chat or formal presentation literature survey or new information Who is the audience? experts in the field, technical public or general public How much time?

Preparation Use one clear statement of the problem, THE TOPIC, the one sentence that will catch the attention of the audience. Use the accepted structure: IMRAD Organize your points from most to least important. The retention of information by the audience gets smaller as you talk.

Preparation Use short sentences with simple grammar. Outline the concepts briefly, clearly, and early in the talk. Assume that you have an unfamiliar audience. Only use the most important concepts. What visual aids go with them?

Graphs, tables, figures Only use those that support your POINT. Communicate relationships early. Use simple two dimensional charts. Minimize the text; use photos. Make them simple and clean. Write explanations directly into the graphic.

Four important design concepts BIG Simple Clear Consistent

BIG design Expand the text until it occupies all the computer screen then stand 2 meters away from the screen. A person in the back of the audience can also read the text.

Simple design Create new slides for this conference. Only use the concepts essential to the TOPIC. When you put up a new slide allow 5 seconds for the audience to absorb the information. Be quiet and then speak what the slide has to say. Be brief.

Simple design Your TOPIC limits the text and restricts the contents of tables or graphs. Your TOPIC Includes only the information that supports it.

Clear design The audience has to be able to read your visual in 5 seconds For the text: Choose a font SANSARIF Select a size from points Use a mixture of upper and lower case Use 10% background color

Consistent design Begin and end the presentation with an identical pair of slides that summarize the TOPIC. At the beginning it is the outline. At the end it is your summary; you finished the story you promised to tell.

The end The audience remembers little. Begin well … and end well; The in between is forgotten. Prepare a great summary: The audience needs to remember the message from your TOPIC.

An oral presentation Is a condensed version of the paper. Is organized around one TOPIC – A clear statement of a problem. Has logic (a string of topics), little text, and clear graphics. It tells a story with graphs tables and pictures.
