Not addressed to the student.
Do not alternate the two landings early. Fly three-points until the standard is met, then switch. Alternating in the first hour is what produces the blend, and the blend is the defect this lesson exists to prevent.
Make the student commit to the attitude targets before flying. The written answer they bring is the point, not its correctness. A student who has committed to a wrong answer learns from the correction. A student who has committed to nothing learns that the instructor knows things.
Name the bounce out loud the first two times, then stop. Standard 4 requires the student to name it before you do, and they cannot get there if you keep taking the callout.
Two hours is a lot of landings. Watch for the point where fatigue starts producing errors that technique had already fixed, and stop there. A student who ends the lesson flying worse than they did in the middle of it has learned the wrong thing about their own capability.
The wheel landing is the one that transfers. It is the technique that gives them the most control in the crosswinds coming in Phase 3, and it is the one they will use most in the Luscombe afterwards. If time runs short, protect the wheel landings.
