I wonder, since Piaget saw development as linear (Rowan, 2016) did he see room for horizontal growth. Example: a young person spend 4 years as an high school apprentice learning the fundamentals in animal husbandry, but needs a college to learn to interpret those skills into a scientific career. How would Piaget see this as linear or horizontal? I understand that Piaget believed that language was linear because it was a system of signs and symbols, but I wondered if he believed all learning was linear. I noticed he seemed to avoid social development. I ask because Piaget saw development in stages rather than a process and his research base was so small.
