Open Educational Resources

Open Educational Resources (OER) are educational materials that are published under an open license. Teachers can access these freely and usually adapt them for their own teaching.
OER can ...

• enrich your own teaching materials with open content from others,
• make teaching materials clearer with photos, illustrations or videos,
• enable collaborative work on and with materials.
