Answer:
d. Vygotsky's concept of the zone of proximal development
Explanation:
Lev Vygotsky develop a concept known as Zone of Proximal Development, according to him, this zone is defined as the distance between what the kid can currently do without help and the things the kid he would be able to do under some adult guidance or in collaboration with more capable peers.
In other words, he believed that kids could achieve more tasks and develop more skills working with someone else who would sometimes help them with the "difficult" parts of the task than working by themselves.
In this example, Nathaniel is 12 year old and he is having trouble solving the word problems in his math homework. His dad helps him by reading the problems and emphasizing the important information and then Nathaniel can solve all the problems. We can see that his dad helped him with the difficult parts of the task and guided him by reading aloud all the important parts of the problems and then Nathaniel could finish the task on his own. Thus, Vygotsky's concept of the zone of proximal development is illustrated in this scenario.
