no, they arent the same thing, and "progressivism" is not an ideology, but an attribute, a direction of society, not a school of thought or system of government. "i dont see where progrssivism succeeded" ... because you've seen it so long you dont even see it any more.
reigning in the power of the king and granting the citizenry basic rights (Magna Carta): progressive
creating a nation under ideals of liberty: progressive
ending slavery: progressive
expanding the right to vote to women: progressive
reigning in corporate excesses, busting trusts, regulating banks: progressive
expanding the vote to minorities: progressive
creatign social safety net: progressive
creating rules to protect the water we drink and air we breathe: progressive
expanding equal rights to LGBT community? progressive
So where is progressivism working? Everywhere it's ever been done, currently that's most of Europe, and to a degree, in the US on some issues).
conservatism is by definition the holding back of society to maintain the status quo, and progressivism the opposite.
As such, both are constantly shifting political forces, and not political philosophies you can nail to a wall for all time.
further food for thought: both socialism(and its kin) and social democracy were created in responce to the excesses of rampant uncontrolled capitalism ("the gilded age"). the difference being social seeks to end it entirely by taking over control of it, while social democracy simply tries to reign in those excesses through regulation, polishing its sharp edges while still channeling its better qualities towards the service of society.
much like the famous quote concerning democracy, capitalism is a rotten system that is ultimately self-destructive....yet still better than the alternatives. so if you can control those excesses, and steer it away from its self-destructive tendencies, you can make it serve society, instead of letting it force society to serve capitalism.
