The non-profit association Serlo Education e.V. has the mission to make high-quality education freely available worldwide. Therefore Serlo Education develops the free learning platform serlo.org. With serlo.org pupils and students can learn independently, at their own pace and independent of the financial possibilities of their parents. The platform offers thousands of simple explanations, learning videos, courses and sample solutions for mathematics, biology and other disciplines. Animations and interactive exercises provide direct feedback and increase user motivation.
Following the example of Wikipedia, the content is created, further developed and checked for quality by honorary authors and lecturers. Currently, 990,000 pupils and students learn monthly with serlo.org. (Text: Serlo e.V.)
