I have been thinking a lot about your recent posts about thresholds and blogs as I’ve been nudging our dog out over actual thresholds in this cold weather. I know your point is to identify threshold and revelationary thinking that results from blogging and social network discussions, but I’m also wondering if those participating in the discussions haven’t traveled over many thresholds already. What sort of learner uses this path? Are they extroverts in the Myers-Briggs definition that rely on external stimuli to clarify their thoughts? Are they primarily visual learners? Are they students that have a limited local community of practice? Will understanding who is successfully using blogging and social networking as an educational tool help educators guide its use by more students with various learning approaches in the future?
