Top-down differentiation refers to the process of categorizing or organizing information, ideas, or systems from a higher level or broader perspective. This approach involves starting with a general concept or overarching framework and then breaking it down into smaller, more specific components. It is often used in education, business, and other fields to create a clear and structured understanding of complex topics. Top-down differentiation allows for a comprehensive and systematic approach to problem-solving and decision-making, as it provides a big picture view while also considering the details. This method is often contrasted with bottom-up differentiation, which involves starting with specific details and building up to a larger understanding.
