Modelling thought processes: I think discussion, rather than lecturing is the best way to understand what gives a person his or her opinions. I don’t believe in experts. I think this kind of reciprocal interaction is also good for differentiating someone’s character, his or her specific way of responding to stimuli, and neurosis, people’s tendency to position themselves as an aberration to social norms, rules of conduct, etc. Neurosis gives us a way to combat “expertise-ism.” Humor is a good example of the power of neurosis; as Kirsten Hyldgaard says in her Lacan.com essay on neurosis and perversion: “Humour and joking are, on the other hand, the neurotic’s breathing hole and playground in the social. Here he can let loose all that the good society would rather was left unsaid and unheard. Laughter and humour is a pleasure or enjoyment that is never innocent” … “A joke has to have a latent “tendency” consisting of hatred, obscenity, and cynicism in order to create the enjoyment of a roaring laugh.” The point is that we’re all neurotic.
Sharing cognitive structures: discussion is again a much better way to do this. Discussion is discursive, can move directions and respond to inputs in a much more flexible way than lecturing. It gives all parties a chance to share cognitive structures. There is nothing in the concept of lecturing that offers a superior mode of reciprocation.
Giving context: discussion creates a much more complex context in which to situate one’s self than lecturing.
Telling Stories: There is also nothing specific to lecturing that provides a better platform than discussion for the telling of stories. Discussion simply allows for more thorough cross germination of ideas and stories. I have found that in my teaching I often end up giving short lectures and telling stories of an analogous form to what we are discussing, ad hoc, on a variety of topics that come up in the discussion that they have little knowledge of, and when I don’t know it, we look it up on the spot. I use networked classroom strategies too sometimes.
