ODL (Open Discovery of STEM Laboratories) equips European school teachers to use micro-MOOC (Massive Open Online Content) – an innovative approach for deploying STEM (Science, Technology, Engineering and Mathematics) laboratories. By applying these to everyday teaching practices, ODL strengthens the profile of the teaching profession. The project will establish a MOOC platform comprising a collection of micro-MOOCs, learning scenarios, open education resources, and STEM laboratories, embed STEM micro-MOOCs in school curricula, and disseminate micro-MOOCs with STEM labs to a wide range of EU audiences.
