Oppia is an online learning tool that enables anyone to easily create and share interactive activities (called ‘explorations’). These activities simulate a one-on-one conversation with a tutor, making it possible for students to learn by doing and get feedback. Our mission is to bring engaging and educational lessons to the community as a means of an extra resource through lessons made by people just like you.
