This is a demonstration model showing how a dual slot rotary encoder can detect the rotation direction. Tell your students to look at the slot marked with the arrow and let them rotate the slotted disk. They will see that turning clockwise will always block out the arrow-marked slot and turning counter-clockwise will do the other one. For construction you will need 3x30mm M3 screws and 3x self-locking nuts. I've whipped this up quickly, it is a bit rough.
