Provides a host of techniques - freewriting, Listing, Cubing - to brainstorm about and refine topics.
Narrow your topic by focusing on:
- Social Aspect
- Cultural Aspect
- Historical Aspect (time)
- Combining two similar topics*
- Combining two or more of the aspects above
* Narrow your topic by joining together related concepts. But beware. The outcome must be feasible, not too narrow, and interesting. This is why you need to perform some background research.
