 My two person class, wow, that was a lot of work at every class that I was so just exhausted after every single one. What I found is that I was able to use some online tools to make that very large class in a lecture hall with non-movable seats and sort of an amphitheater approach to learning. I was able to take that and make it feel more like a small discussion class. I broke the students up into learning communities with 10 students each sort of based on where they sat in the classroom. And then when I would traditionally do a discussion with the entire class or small discussions and then a larger discussion sort of debriefing in a traditional smaller class setting, I had those learning communities have those conversations and I wasn't able to be part of them because there were seven of them. But I had them then post notes from their discussion and if there was a question what they how they answered it online and then after class I was able to go back and look at the student responses and understand where each learning group in that very large classroom was in their conversation about sustainability in human ecology. I could respond to them if there were questions that were arising in one group. I would see it in their online journal and then the next day in class I could bring it up with the entire class. So it was a way to somewhat keep that large or that full classroom discussion going even though that was one of me and at that point 72 of them in the entire class the end project wound up being where I saw the most benefit of lending. The end project additionally had been each student doing an individual research project on a human major coupled system and then presenting it to the class. There was no way we were going to do this with 72 students. No way we could have done 72 presentations. There was no way I could have read 72 final papers. So I again grouped them in groups of three or four and had them do joint research projects had each of them do sort of a variation on a group chosen team and then analyze their different case studies together and do a discussion and reflection together. But this is leaders juniors they hadn't done a lot of group projects before they had a strong distaste for the idea of having to work together in a final project. So I set up these online discussion boards for each of the final project groups and I had them post their case study ideas and then their source list then their case studies their drafted case studies to that journal so everybody could see it back and forth and so I could see what they were doing and give comments and see that and help the dynamic if they were sort of spreading out too much or overlapping too much to help them get a good followed set of case studies that they could analyze together and that wound up being really successful in the presentation so that were more interesting than the individual presentations had ever been. So I decided that that was a format I wanted to continue and the technology made that much more feasible.
