never allowed students to use full flaps on touch n gos for this particular reason - very easy to forget to bring them up.. 2/3rds or 30° depending on type was all you ever needed
What???
We teach 40 deg of flap for every approach on our PA28, apart from practicing flapless and we aren't runway length limiting. It's what the POH says to do. Oh, and 63 kts final approach speed, too. We teach our students to retract the flaps as soon as all 3 wheels are on the ground - also as per the POH. We initially teach a 40 deg flap go-around as a part of the stalling exercises, then later on for real. My favourite scenario is to simulate entering the flare. As soon as the stall warner comes on 'look out, there's a fire truck on the runway!!'. Full power, correct the swing, climbing attitude, then drag flap away, note positive rate of climb, then retract other 2 stages.
BTW, on the PA28, we say 'extend' or 'retract' instead of 'raise' or 'lower', as the latter causes too much confusion with the position of the flap lever. Raise and lower is fine for the Cessna.
