You can teach Science, Social Studies, Arts and Crafts, Magic, etc. Put desks, chairs, a teacher's desk, chests with textbooks (written books), and a "blackboard" (black wool or black terracotta, or use the chalkboard if you're in Education Edition). Perhaps the teacher could have a stock of signs and could use them to 'write' on the board, by putting the signs on it and typing the information.
