Jean Piaget is probably the most influential theorist in the cognitive development realm. His work has informed American educational practices since the early 1900s. Another key cognitive theorist in the realm is Lev Vygotsky. Interestingly, Vygotsky and Piaget were contemporaries (both were born in 1896), but for many years, Piagets theory dominated. The fact that Vygotsky died at age 37, while Piaget lived to be 84, might be part of that explanation. But Vygotskys ideas gained traction in the 1980s when educators began to question long held Piagetian ideas. Nevertheless, both theories are important to the study of cognitive development. In your initial post of 300 words minimum,

• Provide a brief overview of Piagets and Vygotskys child and adolescent cognitive developmental theories.
• Compare and contrast these theories as they relate to child and adolescent development by identifying at least one commonality in the two theories and two major conceptual differences.
• Determine which of the two theories you most support and provide a rationale for your choice.
