Writing a Concluding Paragraph
A conclusion is the last paragraph in your research paper.
A conclusion is like the final chord in a song. It makes the listener feel that the piece is complete and well done. The same is true for your audience. You want them to feel that you supported what you stated in your thesis. You then become a reliable author for them and they are impressed by that and will be more likely to read your work in the future. They may also have learned something and maybe have had their opinion changed by what you have written or created!

A conclusion is, in some ways, like your introduction. You restate your thesis and summarize your main points of evidence for the reader. You can usually do this in one paragraph. In the following example, the thesis statement is in bold. Notice that it is written in 2 sentences. This is a stylistic choice for impact.
Sample Concluding Paragraph
The problem of teen gang violence can be eliminated. It will, however, take time, money, and a combined effort on the part of many people. Organized, free, after-school programs such as: sports teams and games; art, music, and drama activities; internships in local area businesses and professional organizations; and interesting volunteer activities in the community would help engage teens in worthwhile pursuits outside of school hours. More job opportunities for teens, especially those funded by state and local programs, would offer income for teens as well as productive work for the community. Outreach to families through schools, community organizations, and places of worship would help promote inter-generational activities that could improve family closeness, helping teens to work on their problems at the family level, instead of taking them to the streets. If these programs can be implemented, we will surely see a decrease in teen gang activity and safer streets and neighborhoods for us all.
