A brief outline will make it easier to develop topic sentences and to arrange your paragraphs in the most effective order.
1. State your thesis.
2. List the topic sentence for each paragraph. Note that these derive directly from the thesis, and explain, prove or expand on each of the thesis' claims.
3. Expand on topic sentences using examples/case studies.
4. Link the material in your paragraph back to your thesis.
5. Conclusion - Plan to finish strongly, what you have learnt from the investigation, future directions, a personal response to the issue.
