Sites like Quora and Stack Exchange turned this process on its head. Instead of envisioning the Q&A site as a single-purpose forum, the new breed of Q&A site sees the model as half-wiki/half-forum. The question asked is analogous to the title of a wiki page; it’s not transactional but communal. A question like “How can a person increase their chances in the lottery?” is the place where the community will store their collective knowledge on that point, and it is not owned by the person who asked the question, but by the community itself.
Posting a question on these sites is really not about starting a conversation at all. It’s saying “Let’s gather our community knowledge on this particular issue,” just as one might do with wiki.
And this approach – multiple routes into the same concept for the learner – is supported by the research. There are no “learning styles”, as we know – no “kinesthetic learners”. But lost in the discussion about learning styles is the research base that shows that most students benefit from multiple approaches into a subject using a variety of styles. Segregating students into different style groups has no effect, but teaching in a variety of ways is quite effective.
