PowerPoint can be an effective interactive teaching tool if used properly, but it also has some drawbacks if overused or used passively. When used interactively with activities like questions, games, and focusing exercises, it can help students engage with and process information. However, it tends to oversimplify information if it becomes the sole delivery method with too many bullet points and not enough discussion. The key is to use PowerPoint to supplement other materials and activities, not replace discussion or other learning methods.
