We used a variety of ways so that students communicated with each other as well as teachers.

Communication was formal but also informal. We used Twinspace options - Twinspace profiles to know more about each other, Twinmail, Forums, Project journal, Teacher Bulletin. We used also emails, Google Documents, Padlet, Mentimeter, Dotstorming. We have also created facebook group Active Citizen Companies project  https://www.facebook.com/groups/162683861145167/ for out better interaction and this way we can also stay in touch also when we will finish the project .-)
