Note that what is said here is not true. The regs say that you can teach
any maneuver that is "required for a rating" without parachutes. This
includes spins. You can teach a student spins without a parachute(s) if
you wish.

Note that there is nothing that prevents
an instructor from teaching spins to a student pilot. However you would
have to wear parachutes to be legal since the regs only allow spins
without the wearing of parachutes for people training for a flight
instructor certificate.
