This document discusses design methods and tools that can be used in the design process. It covers several learning theories related to design like Kolb's experiential learning cycle, Schön's reflection-in-action and reflection-on-action, and Argyris and Schön's single and double loop learning. It also discusses sensemaking in design. The document then discusses various design methods like prototyping, sketching, and using CAD models. It emphasizes that prototyping allows designers to learn through making and that sketching is an important tool for visualizing ideas.
