hi everyone!
i usually only read in this thread but would like to share my experience about this topic. As most of you said, overcontrol is a thing that happens to ppl students at the early stage (although I have had students prior to their flight exam doing it). Mostly it is due to the nervousness of the student (white knuckles and a stangulation of the yoke). On final approach the aircraft rocks from side to side and the student wants to correct every single error the aircraft does...so the result is (from overcontrol) that the "errors" keep building up. The result is that you see the runway shoot from right to left (and vice versa) through the cockpit window!
As one person in this thread said, relax your grip on the yoke...fly with two fingers and your thumb on the yoke...find a lever for your elbow so you have a handle and a feeling about the inputs you are making...and most important of all...let the aircraft fly and give it some time to react (obviously not if you are going straight to the ground). There is no way you can get a feeling for your aircraft if you are in a continuous fight with it and have no feeling left in your hand due to lack of blood! And be conisderate of the MASS of your aircraft! once you make an input, let´s say to correct your heading to the runway, make a small correction and prior to reaching the point you want to be at, correct the input again because your aircraft will push further due to it´s mass.
when you start flaring your aircraft, keep your eyes at a point further down the runway so you get an impression of the aircrafts flight path! see many students looking straight down the motor-hood...and the result is that the runway nears at an incredible speed resulting in panic and an extreme pull at the yoke...which sends the aircraft straight back into orbit...take a look at the end of the runway, the runway comes up much slower and you can dose your input on the yoke as to flare the aircraft.
i hope what i wrote was half way comprehensible ... my english has become a bit rusty over the years.
Any other tipps or comments are greatly appreciated, seeing that there are so many competent and experienced opinions here!
take care all
