The TEACH Act is basically a rule that allows teachers, instructors, and students to use copyrighted material or content in their online classes without getting permission from the owner of that material or content.
Imagine you want to use a picture or a video in your online class to teach your students about something. Before the TEACH Act, you would have to ask permission from the person who owns that picture or video. But with the TEACH Act, you don't have to do that! You can use it without asking for permission.
However, there are some rules to follow when using this material. You can only use it for educational purposes in online classes and only for a limited time. You also have to make sure that only the students who are registered in the class can see the material, and you cannot share it outside of that class.
The TEACH Act allows teachers and students to use copyrighted material more easily in online classes, but it also makes sure that the material is used in the right way and only for educational purposes.
