Answer:
The answer is the change and acquisition phase.
Step-by-step explanation:
The acquisition phase consists of a change in which the individual can perform a new skill after he or she could not perform it. However, he or she can only perform it with assistance. This period occurs when the learner cannot respond properly when he or she doesn't have any kind of assistance.
The end of this phase is when the learner can perform a new skill independently. It means that he or she can do it without any kind of assistance. When a learner can respond properly without any kind of assistance we could say that he or she is at the independence level.
