PowerPoint is a Microsoft software application for the design and delivery of speaker-support slides. With more than 300 million users worldwide and 30 million PowerPoint presentations delivered each day, Microsoft now dominates this market. PowerPoint was originally designed for the creation of 35mm and OHP slides, but these days the slides are typically projected directly from a computer.
In an educational context, PowerPoint can be used as a means for teachers to support their classes with visual aids, and as a way for students to present the results of their projects. PowerPoint slides can also be used as stand-alone handouts and reference material.
