For any data flow diagram first look at the existing processes. Student registration, class selection, professor/teacher class assignment, testing, grading and I am sure the list goes on. Once you have provided the beginning scope of the software by pruning the list of existing processes you can then develop a list of documents and communications that are used to transfer information and authority to others in the system. It is these documents and activities that are data flow items. The entities that are involved in sending or receiving these same communications are nodes in the system. Of course this is cursory and very general answer.
Which UML diagram is drawn first depends on the software design process, system analysed or designed, etc. If you start by collecting requirements, your first diagrams will be use case diagrams. If you start by existing system analysis, it could be class diagrams of domain model. If you create some services, you might start with component diagrams. If your system is in specific domain, you might start with profile diagrams...
