During my flight instruction, the club CFI told me that stall, spin, crash and burn was something I should practice solo.
Seriously though - becoming familiar with slow speed fight, incipient spins, wing drops at stalls, the back end of the lift/drag curve is very important. Do this by opposite rudder, and steering into the wing drop with the stick to reattach the airflow. Practice, practice, practice to minimize height loss. As a glider pilot, I find it's best to develop the right technique by keeping the throttle at idle during this. In real lfe situation - open the tap as well.
It is also very satisfying to practice high rate turns at constant altitude. Keep a good look out, and enjoy the kick of flying through your own slipstream. 360s and figure 8 turns both work well.
