I need help with the following queestions:

What did Vygotsky mean by Child-in-Activity-in-Context? What is culture? What is the Zone of Proximal Development? What is Rogoff's idea of guided participation? What is Vygotsky's dynamic assessment? Explain the phrase "The intermental constructs the intramental". How did Vygotsky's ideas mirror and differ from Piaget's in the internalization of interaction between the child and the world? Compare and contrast Vygotsky and Piaget in their analysis of egocentric or inner speech, focus on Vygotsky's developmental approach in this area. Discuss Vygotsky's approach to the dialectical process. How did this approach differ from Piaget's? What are the strengths and weaknesses of Vygotsky's theory and the contextualists?
