Final answer:
The 'Refreezing' stage of Lewin's Change Theory is when change is fully integrated into practice, following the 'Unfreezing' and 'Changing' stages.
Step-by-step explanation:
The stage of change in Lewin's Change Theory where the change becomes integrated and stabilized into practice is referred to as 'Refreezing'. This is the final stage after 'Unfreezing' and 'Changing' (or moving), and it is where new behaviors are solidified and become the norm within the organization or individual's routines.
The stage of change in Lewin's Change Theory that describes when the change is integrated and stabilized into practice is refreezing. During the refreezing stage, the new behaviors and practices become the norm and are reinforced. This helps to solidify the change and prevent a relapse back to the old ways.
