it is interesting to observe how people's creativity and motivation to share their ideas change when the environment they are usually at changes somehow. I notice one day that my students were more willing to share their ideas in class when we decided to have class outside sitting on the floor and free to eat our lunch there. some students who never have shared or contributed to the class did that day. I believe that the simple fact that we felt free of a restraining environment and sitting arrangements infused in us a different non threatening feeling where we felt free to share and be more involved in class.
