Did you ever need to cover a lot of information and you do not precisely know what the level of knowledge of your audience is and what they are precisely interested? The pitfall is if you try to cover all the information as (1) you may provide an information overload (2) you will not focus on what is of most interest for your audience (3) you end up covering all the topics at a too high level and therefore not providing a meaningful experience for your audience. What to do to avoid this situation?
You may turn your presentation in a questions and answers session. Ask your audience before the presentation to send you questions. Considerer showing the an overview with all the topics, so you can direct the questions. You can also ask this at the beginning of the presentation and give your audience pieces of paper and pens to write down the questions. Put the pieces of paper with questions in a box and take out a question and dive in to the details to provide a structured answer. By means of this you have a visual interesting aspect to show and cover what is of interest for your audience. At the end of the presentation you do need to provide reference to where your audience can find the information about the topics that you did not cover during your presentation.
