Schools do a disservice if they teach stalls with the nose pointed at the sky and spins as mysterious and hard to recover. The chief purpose in teaching both is to enhance your ability to recover.
Remember that stalls happen in any attitude; nose pointed straight up, straight down, or straight and level. A spin is a stalled condition with rotation; roll and yaw. In most cases, both rotations can be stopped with opposite rudder; that leaves reducing angle of attack (stall) and recovering from the descent. That's it.
You can't spin if you don't stall. It doesn't matter the altitude. If you can do a stall recovery (which implies a stall recognition), you can prevent a spin; while it is possible to spin an airplane at an altiitude that's too low to recover, the name of the game is preventing the stall that leads to the spin, and some exposure to stalls and spins is good to help you recognize and impart preventative measures early.
Enjoy it in small airplanes, which is where much of the fun in flying takes place. We don't really stall or spin big airplanes.
