if anyone is interested... here is an easy way to practice upbow/downbow staccato. for upbow staccato, play fast sixteenths at the tip (with your hand and fingers providing the motion)then while doing that (not actually having your fincers and hand at the tip), do an upbow with your arm at the same time. you should be relaxed in your arm and hand while practicing this. for downbow staccato do fast sixteenths at the frog etc. hope this helps someone.
