Being vectored to final approach in IMC with ice accumulating on aircraft.  Was only able to maintain ATC assigned airspeeds by configuring the aircraft with flaps 20 AND the use of flight spoilers (to keep N2 high enough to shed ice).  Approaching Final Approach Fix; aircraft was fully configured for a stabilized approach; but airspeed was still Vref + 30; so the flight spoilers were reintroduced.  The aircraft immediately pitched up 5-10 degrees; the stick shaker activated; and the autopilot disengaged.  Aircraft was manually pitched back into the flight director command bars.  Thrust levers were retarded to achieve target speed. Captain is currently finishing IOE and has limited experience in this position.  Flight crew did not realize the extent of ice accumulation.Pilot position inexperience; unreasonable speed requests by ATC; time in icing conditions; failure of flight crew to fully appreciate ice build up on airframe and resulting flight characteristics.  Flight crew should have declined ATC requests for slower and slower airspeeds; which necessitated thrust levers to idle and did not allow anti-ice equipment to function properly.  More attention from flight crew to notice buildup of ice.
CRJ-200 Captain under training reports being vectored in icing conditions; at low airspeeds and attempting to keep N2 high enough to shed ice and using flaps and spoilers to maintain requested airspeed. At the FAF spoilers are extended to kill excess airspeed without reducing thrust and the aircraft immediately pitched up 5-10 degrees; the stick shaker activated; and the autopilot disengaged. The approach continues manually.
