The Khan Academy creates small, very simple explanatory videos. The organisation initially focused on mathematics, but has now grown to encompass many other subjects. The initiators believe that it is easier for children to learn at their own pace, and that it helps if they can fast-forward a video, for example, or repeatedly view a certain part of a film. The project was originally intended as a supplement to be used outside of classrooms, but its content is increasingly being used directly by teachers.
The academy enables learning to be conducted through a ‘flipped classroom’ approach – learning takes place at home, whereas the time spent at school can be used for discussions and to answer specific questions. In some subjects, the videos can also be watched independently. The academy has put together complete learning programmes, coupled with tasks that can provide immediate feedback about whether answers are ‘right’ or ‘wrong’, but without issuing a grade. The individual learning paths can be viewed by the teachers so that teachers know when students need support and in which subjects. The Khan Academy continually expands its courses and content and also regularly translates them into new languages. The classes are free and available to anyone with internet access.
