Ompare and contrast Piaget and Vygotskys models of cognitive development in children

Please try to avoid writing in first person it has to be written in third person. Since it is a compare contrast format I really want good examples of similarities and differences between Piaget and Vygotsky. please only talk about Piaget and Vygotsky not anyone else. Please make sure you are writing Piagets and Vygotskys model of cognitive development in children. I need references within the text as well. on the reference list I need them in alphabetic order. Please make sure you use academic books and journals. My university is really sensitive about online resources. So make sure all of them academic ,sources. This essay is really important for me. Looking forward to get an academically well written and supported essay. Thank you very much.
