How Poor English Speakers Make Clear Presentation

Today a guy with very poor English made a even poorer presentation in English. A presentation with same amount of information is made in twenty minutes by a normal English speaker, he used one and a half hour. However all audiences (fluent English speakers) were very patient and nice. They waited until he finished. In stead of making comments on the topic, they gave some suggests to the speaker on how to make a clear presentation. Here are some suggests they gave.

• Write down most of the information you want to send to the audiences. As you have problems on speaking clearly, you should write down as much as information as you can on the slides. If the audiences cannot understand what you talk, they can still get the information of the topic from reading your slides. Also the speaker you can just read out the slides if you cannot talk freely. This is not a nice way to make presentation but it guarantees that the audience can understand the topic.
• Make a detailed introduction to the topic. Do not mind to spend a bit more time on introducing your topic. If the audiences know what the topic from the beginning, they can guess the meaning that you want to express from their knowledge or experience when you cannot express clearly. If they do not understand what you talk about from the beginning, they cannot get any information from your presentation at all.
• If there are mathematical equations in your presentation, explain the notation (which notate the variables and parameters) in the equations clearly. Do not assume that everyone understands the notation you use. If they do not know what the notations mean, there is no way for them to understand the equations (usually these are the core information you hope to give to the audiences) you create.
