Checks before a steep turn? Instructor has a quick look at the Ts & Ps, and a discrete but thorough look in the direction of turn, then calls out an imaginary close contact! Teach them what it's really for, and that whatever they might be expected to do in the test, gaining or losing 1-200' is less important than hauling the aircraft onto a heading that is not in conflict with another flying piece of steel!
I even demo the max-rate turn, to show them that the aircraft will (a) roll really quickly if you use lots of rudder too, roll rate being important at this stage, (b) stay in one piece as long as you're below the yellow arc and (c) turn level at more than 60°, so slight overbanking need not result in a panicked spiral descent. Oh, and (d) stall and enter an incipient spin if you take it too far into the buffet.
