1. Vygotsky's theory of cognitive development (sociocultural) • Development, social interaction, language, and culture • Social interaction and development • Language and development • Culture and development

2. Vygotsky's theory of cognitive development (sociocultural) • Piaget thinks children depend on their own to explore, form ideas, and test these ideas with their experiences • Vygotsky emphasizes social and cultural influences on the child's developing mind • Cognitive development is influenced by social interaction, language, and culture

3. development is influenced by social interaction, language, and culture • Culture • Cog.Development • Social Language Interaction

4. Social interaction and development • Learning and cognitive development arise directly from social interaction • A child acquires knowledge through interacting with more knowledgeable others (adult, or child) • The child develops an understanding that he wouldn't have been able to acquire on his own. • Piaget proposed that children explore the world individually

5. Social interaction and development • Vygotsky suggested that children need not, and should not, reinvent the knowledge of a culture on their own. • Adults explain, give directions, provide feedback, and guide communication • The child is actively involved in the interaction with the adults by doing.

6. Language and development • Language plays at least 3 different role in development according to Vygotsky's theory • 1. Through social interaction, language gives learners access to knowledge others already have. • 2. Language provides learners with cognitive tools that allow them to think about the world and solve problems • 3. Language serves anindividual function; it gives us a means for regulating and reflecting on our own thinking

7. Language and development • Private speech: is self-talk that guides thinking and action. • Piaget termed it "egocentric speech" • Vygotsky believed that private speech "seemingly targetless mumblings" indicates the beginnings of self-regulation. • Private speech, first muttered aloud and then internalized, forms the foundation for complex cognitive skills such as sustaining attention, problem solving, and memorizing new information

8. Culture and development • Culture provides the context in which development occurs • The language of a culture becomes a cognitive "tool kit" (belongings) that children use to conduct their interactions and make sense of the world • Culture provides a mechanism for both communication and thinking
