Almost every flight school specifies a too high approach speed. If the aircraft is flown at the correct approach speed then you should be able to slowly but continuously raise the nose to the landing attitude, hold that, and have the aircraft settle on to the ground with no further pitch change required.
What I see far to often is a too fast approach with excessive float as the poor student ballooning on the first attempt to flare followed by a series of divergent pitch and altitude excursions and the student attempts to pitch to a landing attitude followed by either a nose wheel first touch down or a hard landing as the aircraft runs out of speed and falls out of the sky.
With 2 up and half tanks, if you are flying your C 172 or Pa 28 faster than 60 kts when you cross the end of the runway you are going too fast.
