For teaching, I use Evernote to create lessons, feedback and homework. I teach English as a second language 90 % online via Skype, mainly on a one to one basis. In oder to use the lesson time optimally with the student i.e. more student-centric, I send activities that I have created and stored in Evernote via mail that the students have to prepare beforehand (similar to the ‘Flipped Classroom’ pedagogy).
