Use a concept map to put down all the information you have gathered and it will help you see how you can link things together and what relates to the main idea for the assignment. Look at three different ways to try.
The following axial map puts key words of your provisional thesis statement at the centre with your data (points taken from your notes) radiating outwards.
Assuming that there are three themes or points that you will develop as your key elements, you can draw a map with three category sections, into which you will sort your data.
If there are points covered by notes that don't fit into a category, they probably don’t fit in the essay or you may consider another theme section, if you see it’s important enough to be included.
The Fishbone concept map is useful for an argumentative essay. It allows you to view all the points for and against your provisional thesis statement and to evaluate the comparative strength of each side of the argument.
