Thanks for the additional details @patricia_yokogawa - So if I'm understanding correctly, you are using Twitter as the feedback mechanism.
I keep thinking about the main reasons I choose to use Twitter for an activity, or another tool. For me, Twitter is a way to a) connect to people OUTSIDE the classroom, b) get learners used to having a public digital identity (critical for many professions) and c) to work "in public."
Their other work is in Moodle. Is the Twitter use so we, the wider #UDGAgora folks can see the work? So you can connect your students to the outside world? Say more please! I'm really enjoying digging deeper into everyone's. challenges!
