First, I want to thank you for the great material the site gives access to, although it would be easier to use for our students with a less complicated access.
What I use in my classes (physics and energy topics) – I have used creativity tools, some of the ones that are presented in the MOOC are familiar, some were new. I also have the students to arrange events (showcases of study results, cooperational projects with industry) in 4-5 person teams. I have noticed that this increases many ‘soft’ abilities (plan together for common goal, communicate, teamwork, presentation).
