So, when I first know "critical thinking", I feel that my mind is free to open but do not have the ability to organize it well. That was the moment when I realized that I need to practice the way of think in order to let people follow my idea.
Ok, back to the topic- Discourse Community. In my major, architecture, require a sense of feeling the form and establish your idea in a strong, persuasive and attractive dialog. Most of the topic are linked to the popular discussion in the architecture like "sustainability" or "movement". So, most of the time if you really want to get into the topic, you need to provide a opinion which, first, can be agree with most of the audience but there are some don't, second, have a further discussion value. Then, the air in the studio will became more active and you will be able to add more things into the conversation since it is you started the topic. After a long time of that, you will get what others think in gernaral and therefore you can make your place in the community by sharing the idea each other interested.
