Ms. Leverett has adopted a new approach for teaching students to develop persuasive arguments. She models the process, coaches students as they practice, pairs students to explain their thinking, receive feedback, and reflect on new learning. Then she assigns the complex topics for debate. Her process demonstrates one application of Vygotsky's principles. It is an example of:a) eciprocal teaching b) A cognitive apprenticeship c) Sociocultural problem solving d) Proximal development
