Yes, the order in which you write the essay might go like this:
Write a paragraph about education in Columbia.
Follow it with a para about Ed. In the U.S.
Write a paragraph that compares the two based on certain points.
Write a very thoughtful conclusion paragraph in which you reflect on the IMPLICATIONS of the differences between them.
When you are all done, go back and write an intro paragraph that grabs the reader's attention, introduces both things being described, and tells the reader your main idea -- your main opinion about the two in relation to one another.
