In line with the conference theme, this workshop will “expand the horizons” of Learning Analytics (LA) by bringing together researchers and practitioners from a wide variety of backgrounds to create a community-accepted list of grand challenges. It will work towards finding common elements in various existing research programs and mapping out the new research avenues that are deemed most interesting by the community. This will help the LA community to point to well established “blue skies” requiring more work when applying for funding and large grants. It will also support more junior researchers in seeing the bigger picture when plotting out their research trajectory.
