PowerPoint is a presentation software tool that allows users to create on-screen presentations using text, graphics, audio, and other media. It is useful in teaching and learning by enabling teachers to present information in engaging ways using various media. Students can also use PowerPoint individually or collaboratively to practice and reinforce skills. However, PowerPoint presentations need to be designed carefully to maintain audience interest and avoid distractions, with an appropriate amount of text, graphics, animations and interactivity based on the audience. The effectiveness of PowerPoint depends on its proper use.
