The approach speed is normally 1.3 times the stall speed in a given configuration.
Ie you may land with full flap, part flap or no flap.
The idea is to land as slow as possible and as close to the stall as possible to get the shortest landing run as possible.
It is a slight misconception that stall and landing are set in stone as they are infact seperate.
We had another thread where I stated that infact if you had enough skill you could land an aircraft at its cruise speed!!!
You would have to be very accurate and you would take forever to stop but the high speed bounces are indicative of lacking in skills not landing an aircraft at high speed.
OK all that maybe an unreal example but one to make a point.
In certain conditions ie strong winds shear and turbulence it may not suit to land or be in a situation where you are holding off waiting for the aircraft to get near the stall and sink on the runway.
For training purposes that is the technique to go for ie hold 1.3 times the stall in a given configuration then concentrate on landing the aircraft near the runway slowly increasing the AOA so that you land as slow as possible.
