Stepper motors are specialized motors that precisely control the angle of rotation of the shaft of a motor. They are often used to carefully position items that move along an axis. For example you can use stepper motors to control the position the printing head of a 3D printer. Stepper motors are also quite a bit more expensive than our DC hobby motors and mini servos, so we don't use them frequently in our classes.
