What Oppia is
Oppia is a free learning platform for interactive educational content called explorations. Lessons can combine text, pictures, video, multiple-choice questions and typed answers. The platform identifies common wrong answers and provides tailored feedback, while playful characters and varied strategies help reinforce knowledge. Teachers can customize lesson formats, create lessons on chosen topics and share them. Oppia lessons can complement classroom teaching or support self-paced learning at home, with regular progress updates for parents and guardians. Classroom lessons are reviewed by teachers and experts, and Oppia says it conducts user studies and randomized trials. Its stated focus is serving under-resourced students around the world. Access is available on the web, Linux, macOS, Windows and Android, including a native Android app. Volunteers contribute software, art and design, translation and lesson creation. Licensed educational content is provided under Creative Commons CC-BY-SA 4.0. Oppia prohibits harassment, privacy violations, infringement, hateful content, malicious code and disruptive activity.
