Presentation Feature: Explanation
What is it?The presenter explains the meaning, significance or background of the issue they are addressing, or the model or image they are presenting.
Why is it important?The audience does not have the same extensive background knowledge of the topic as the expert presenter. They may not even be a subject expert. It is important, therefore, that the presenter explains the meaning of subject-specific jargon and acronyms in order for the presentation content to be accessible to the entire audience. The presenter may need to provide a context for the audience to be able to see the significance of what he or she is describing, or for them to describe or show explicitly how their topic relates to a wider issue.
How is it done?The presenter may ask a rhetorical question such as, ‘What do we mean by SFL?’ or ‘How does this fit with current models?’ and then go on to answer it. They may point or highlight something on the screen and referring to it as ‘this’, describe what it shows, or what significance it has. On other occasions, they may simply give examples directly after mentioning a broad term, so that the audience recognises the examples and can understand the broader concept. Another way presenters make a difficult concept clearer to an audience is to provide a similar example in a context which is more commonplace and familiar to the audience.
