I do that, too! This term I used (what now seems kind of creepy) a hidden "human glossary" full of student info that popped up throughout the first few weeks of class as a cheat sheet to help me better connect with students. It helped! I don't need it now, but in those first few weeks I depended on it. I guess it is the virtual equivalent of the sketched seating chart I would fill in as people arrived every day for the first few weeks of a face-to-face class? Yes - quiet work is happening.
This is why I always wonder about evaluating visible participation in a participation grade in online courses. One Yukon College instructor developed an algorithm to help calculate quiet participation in her courses. When she looked at the Moodle logs she would notice some students spent hours visiting every page/post, but actually posted very little - she wanted to honour their quiet learning as participation.
I like the idea of having students share strategies they use to connect with (or even just remember) each other. Gina and I were thinking that if we had more time in this MicroCourse, it would be interesting to hear folks' experiences of when they most felt "community" in a course (as a student or facilitator). We might need a follow-up MicroCourse...
