A primary school teacher, Ms. Ramirez, wants to design a geography lesson on spatial perspectives and map-reading for a class containing both 5-year-old and 9-year-old children. She decides to use the theoretical insights from Piaget and Inhelder's (1956) 'Three Mountains' study to structure her lesson.
Describe how Ms. Ramirez could adapt the methodology of Piaget and Inhelder's original research to assess the perspective-taking abilities of the children in her classroom.
Explain what Piaget and Inhelder's findings tell Ms. Ramirez about the differences in cognitive development between 5-year-olds and 9-year-olds, and how this should influence her teaching approach.
