"Research has shown that visual learning is one of the best methods for teaching thinking skills. Visual learning techniques — graphical ways of working with ideas and presenting information — teach students to clarify their thinking, and to process, organize and prioritize new information. Visual diagrams reveal patterns, interrelationships and interdependencies. They also stimulate creative thinking."
