Spin entries? If you mean that yawing/rolling feel, you get that long before you are spinning, and my experience giving primary flight training tells me they'll get that on their own during initial stall training without me having to deliberately set it up. I then tell them that's what the beginning of a spin entry is, and when you feel that, you get on the opposite rudder to stop the yaw and forward on the yoke to reduce AOA before things get worse. That's the point at which the situation must be reversed -- before they get to the point where if it happens in the pattern, they won't have enough altitude to recover.
I put this in the Dr. Groucho Marx category -- if it hurts when you do this, don't do this, and since it usually happens too low to recover, entering an unintentional spin has too much chance of hurting, so just learn not to enter unintentional spins. If you want to learn more about aerobatics (and spins are most definitely aerobatic maneuvers), go to one of those emergency handling/intro to aerobatics courses once you've got your Private done. But in the mean time, learning to avoid entering unintentional spins is quite sufficient.
Furthermore, many of today's primary trainers are not spin-certified, so you'd have to go to a different airplane for that training, and in many cases, the flight characteristics of the spin trainer would be significantly different than those of the primary trainer, creating the potential for negative training transfer.
All in all, the FAA and I are both satisfied that training in intentional spin entries and recoveries from intentional spins simply doesn't reduce the number of stall-spin accidents, but does lead to fatal training accidents. OTOH, training in avoiding unintentional spins had been shown to reduce unintentional spin accidents.
