People learn through experience and clear examples. That's why classrooms and meetings are full of images, maps, and graphs.
But the teaching only starts there. It's the teacher's responsibility to give context to the material. A good teacher communicates effectively and provokes different trains of thought amongst students.
Meanwhile, it's the student's responsibility to be curious and ask questions. A good student thinks alone but bounces off ideas within the classroom.
Teaching and learning are reciprocal relationships that lean on an open forum. So while visual examples explain everything, they don't make sense until the material in them gets talked about or written down.
