I think that you shoud consider to add forein keys and constraints,
before consider normalization.


For Example:


> - a teacher can teach several courses




Add reference to StaffNo(Primary key of Teacher table) to Cource table.


> Course(CourseNo, description, TeacherNo) (TeacherNo reference StaffNo of Teacher table)
