Answer:
within Josie's zone of proximal development.
Explanation:
Zone of proximal development: In psychology, the zone of proximal development was introduced by a famous psychologist named Lev Vygotsky and is also denoted as ZPD.
ZPD is defined as the phenomenon that describes an individual's capability of performing a specific task with guidance versus independently i.e, the set of knowledge or skills that a learner can do on his or her own versus with the help of the teacher or a guide.
