Very simply, the control column controls IAS and power controls RoD until the aircraft is aimed at a fixed touchdown point. As the attitude is now fixed, small power corrections are made to correct speed errors whilst small control column movements are made to keep the touchdown point fixed in the windscreen. Students find it far, far easier to roll out of the final turn, lower full flap, adjust attitude to obtain correct IAS and then use 'point and power' on the approach, constantly adjusting the attitude to keep the touchdown point fixed with small control movements as small power adjustments are made to maintain approach IAS.
