First you should draw the class diagram. Using the class diagram you can identify objects. Sequence diagrams shows objects interactions, message flow between objects. As you are developing a LMS possible objects might be Student , Course , Assignment , Subjects etc..

These are guidelines. You can bend some of them to suite your needs.However, sequence diagrams are useful since they will provide the flow of your program.
