Please do not say 'by using one handed weapons', is it calculated by the number of times you swing it or the damage output, does it matter which weapon you are using, i/e, will a dagger get more, less or the same exp as a sword or mace perhaps?

Number of hits and quality of item/base damage. A Dragonbone mace will level it more quickly than a dragonbone sword.
Skill xp gained is indeed based on the base damage of the weapon.

Indeed. A mace in the main hand and a dagger in the off hand will yield the fastest results.
