Summarize this article:

Pick something that you know best, or learn about something new and tell the world what you have learned.   Determine what kind of educational video you want to make:  Will this be a “how-to” video, or will you be providing in-depth information on a particular topic? Will there be interactive activities, or will you be talking throughout the video?   Make an outline of how you want your video to proceed before you start filming. Adequate preparation for your educational video is key. Many people (especially those who are camera-shy) are more comfortable speaking in front of a camera once they have rehearsed what they want to say.  Make sure you have your facts correct. Before making an educational video, double-check to make sure that the information you will be providing is correct. You don’t know how many people will watch this video! The key to creating an educational video in which you seem like an expert is to be confidence in your message. The best way to gain this confidence is through repetition.   Practice in front of a mirror. Doing a run-through of your script with no one around to judge it can be a good way to iron out kinks and gain confidence. Practice with a friend, and have her give you feedback. It may be beneficial to have another person listen to your script before you film it and publish it. If possible, practice speaking from memory without the assistance of notes. Think about the message you are trying to convey, and locate any props that will make this message clearer and your video more stimulating.   Watch other educational videos to see if and how they effectively use props. While it is important not to directly copy any other video, you may be inspired by what you see on other videos. Remember that a prop can be as simple or as complex as you want it to be. There are no specific guidelines to creating your own educational video! The props that you use in your video will be unique to the topic you are presenting. Remember that speaking in front of a camera can feel a lot different from speaking in front of your mirror. The more practice you can get, the better your video will be.    Film your dress rehearsal if possible. This will allow you to watch it over, review your performance, and identify any mistakes you may have made. Ask a trusted friend to watch your video and provide critiques. A neutral third party may be able to better identify errors or potential distractions in your video.

Identify your topic of interest. Prepare a script. Practice your script. Get any props you may need. Do a dress rehearsal.
