The museum of modern art (MoMA) provides us with a very accessible and informal course on modern art. You will explore four themes–Places & Spaces, Art & Identity, Transforming Everyday Objects, and Art & Society–whilst learning about artworks from The Museum of Modern Art’s collection. This course serves could inspire to teach arts thematically. However, the course could be more profound and in depth.
You can find the course on Coursera.
