Theories of cognitive development

Compare and contrast the theories of cognitive development put forth by Piaget and Vygotsky.

Use the following scenario: you are a second-grade teacher and are writing a lesson plan to teach math facts (addition and subtraction).

• Based on Piaget’s theory of cognitive development, what materials would you incorporate into your lesson plan? Be specific and explain how your plan is driven by Piaget’s theory.
• How would you change your lesson plan based on Vygotsky’s theory?
