How do we know that any learning happened? How can we possibly organize all the work that students are doing so that they can find each other’s work and so that I, as an instructor, can review all their work? These (and many more) are some of the difficult practical issues around the PLE PLN in the classroom. In the course I linked to in the last section, I put the onus on the students to copy/paste a link to each of their blog posts, to important comments they had made structuring other people’s work (one of our students or not) and important connections that they had made between the information/knowledge we were covering and their experience during the course.
