Wikiwijs is an online platform where teachers can search for, use, and share free educational materials. It is specifically developed for education in the Netherlands, with a stronger focus on primary and secondary education, and provides a central place to find open learning resources across different subjects and levels. Users can access a wide range of materials without an account, including lessons, assignments, tests, and complete learning pathways.

The platform encourages the reuse and adaptation of teaching materials. Teachers can easily modify existing resources to better fit their own classroom or teaching context. In addition, they can upload and share their own materials with other educators, often under open licenses that allow others to freely use and adapt the content.

Wikiwijs also offers tools for creating educational materials, for example by combining different resources into a cohesive lesson or module. This makes it not only a platform for finding content, but also for actively developing new materials.

By promoting knowledge sharing and collaboration, Wikiwijs contributes to more accessible and higher-quality education. It helps teachers save time, gain inspiration, and improve the quality of their teaching materials.
