Here's a simple outline for you to use!
1st paragraph: Thesis statement (such as "There are many benefits of online learning."), quick summary of the topics discussed in your essay. Shouldn't be any longer than maybe 4-5 sentences.
2nd paragraph: Topic example: Students gain better time management skills (go into detail).
3rd paragraph: Topic example: Improved virtual communication and collaboration (go into detail).
4th paragraph: Topic example: Demonstrated self-motivation (students are forced to take responsibility for turning in assignments, since they don't have a teacher physically in front of them to do so) (go into detail).
5th paragraph: Restate thesis statement, summarize the topics once more. Shouldn't be any longer than maybe 4-5 sentences.
