The Oppia team works to create effective, enjoyable online lessons at scale that can reach millions of people. We want every individual, no matter what their personal circumstances, to have access to learning experiences that are not only pedagogically effective, but also fun and engaging. Our focus is on reducing the equity gap in access to education, and we are currently working on providing free and effective basic math and science lessons that can be played on cheap Android devices to learners in underserved communities around the world. Oppia's lessons have already reached over 2,000,000 users, and learners using our basic mathematics curriculum have seen gains of over 50% from pre-test to post-test. You can read some examples of our work in these blog posts https //medium.com/@ebelubhuhiose/86b97283edf4 and https //medium.com/@ojobusayo99/6e783aaddb74 .A key differentiator of Oppia is its unique technology platform, which simulates an interactive tutor by adapting each lesson to individual learners’ needs and providing specific, targeted feedback to help them improve. Furthermore, all our lessons are openly licensed and the platform is open source, which enables a diverse group of educators and technologists from around the world to regularly iterate on and improve them. Hi all!The Oppia Foundation is looking for volunteers to help voiceover math lessons. These math lessons are designed to be a novel and engaging way for students to learn or enhance their basic math concepts (e.g. addition, subtraction, division, multiplication, fractions). To make these math lessons more engaging for students, they have the option to listen to the audio as they read each lesson.We are looking for volunteers to dedicate some of their time to help voiceover the math lessons in any language. This will be an excellent opportunity to practice your reading skills/speaking skills, to add some extra volunteer hours if needed, or to just volunteer for a better cause.This is a volunteer opportunity provided by VolunteerMatch, in partnership with LinkedIn for Good.
