Answer:
shaping
Step-by-step explanation:
The teacher simply made use of successive approximations to help Penny draw the letter Q, this is mostly related to the shaping process.
The shaping process is employed if one wants to develop a target behavior which he or she doesn't currently have or exhibit.
Shaping is defined as the differential reinforcement of successive approximations of a target behavior until the person exhibits the target behavior.
This can be deducted from the action of Penny's teacher continuously watching her try writing the letter until She achieved the required result or mastered the writing of the letter.
