“A presentation is a form of communication with an audience.” Keio University
Presentations are often given alongside the use of PowerPoint, Keynote or other slide show software but may also include audio files, videos, Flash animation, animated computer screen grabs and many more multimedia elements that can be shown within a web browser or specialist program such as Impatica. These presentations and word processor versions may be uploaded to a Virtual Learning Environment such as Blackboard for use by students.
