The Pilots Operating Handbook for that aircraft should be consulted with regards to recovery technique. Leading with power could worsen the effect of the stall or even flip the aircraft over (Cessna 152).
SSR technique for training aircraft is control column forward, full power or CC forward together with full power. As HFD has said, students do tend initially to Stuka dive the ground. Recovery with minimum height loss is the objective. I’ve found some aircraft can power out with minimal decreased pitch attitude, others not.
