Pace
Let us take the average PPL student in his 172. He is taught to set 30deg flap and 65kts on final approach to land. If he lands, he will ensure the aircraft is under control, vacate the runway, clean up and taxi back. If at any point on the approach he needs to Go Around, he will apply full power, select a suitable attitude to arrest descent, remove one stage of flap to 20deg and then select a suitable attitude to climb away. He will subsequently raise the rest of the flap at some point where he isn't close to the ground and reposition.
Take the same chap who is doing T&Gs. The approach and landing will be the same, notably using 30deg flap. He will then raise all the flap, maybe adjust the trim, keep the aircraft aligned with the centreline and finally apply full power to take off.
The final scenario. The student pilot plans on landing (or indeed a T&G) but bounces (Touch?) the aircraft. At this point, you and I would probably do something rather clever with power to recover the landing. Without exception, every training school i have ever know teaches the low-time PPL student to throw this landing away and try again. So, the aircraft is about 5-10ft above the runway with speed decaying and AOA approaching a scary number. At this point does the student do his T&G checks (raise flaps to T/O, achieve centreline then add power) or does he do his G/A checks (full power, appropriate attitude, gradually retract flaps)? The argument is similar in the event that the student pilot cannot maintain enough directional control to keep the aircraft on the runway.
Keep it simple.
