Ideas should be introduced in a logical order, so that each lays the foundation for the next, culminating in your final conclusion. Make sure that the conclusion relies on the main points for support. The conclusion should systematically summarize the main ideas of the study, maintaining the order in which they were presented. Coherence Aim for good writing style. You want your writing to be a pleasure to read.
Graceful writing is persuasive and effective writing.
If an essay is difficult to read, then the audience will not be in any mood to accept new or challenging ideas. Use key terms throughout the writing to refer back to the thesis and join the main ideas. Summarize key points at the end of your discussion of each main idea. This reminds the reader of the points you have already made, before plunging ahead to the next level of development. These are clues that let the reader know how one idea is linked to another, and when you are going from one point to the next.
