Boston Public Schools is using a different world map in an effort to decolonize classrooms.
The school system is changing world maps for certain grades from the traditional Mercator projection to the Gall-Peters projection, which more accurately represents the size of continents in the global south.
The initiative is a joint effort between the district’s Social Studies Department and its Office of Opportunity and Achievement Gaps in an effort to increase cultural proficiency across academic disciplines, said the school system in a statement.
The key differences between both maps are the size and shape of the continents.
“The Mercator projection is actually a map for sailors — it was designed for navigation in the sixteenth century,” said John Pickles, a UNC geography professor.
The Mercator map was used during the Cold War because it showed the most powerful regions, North America and Europe, as the two largest geographical areas, Pickles said.
“What it did in particular was marginalize the geographical importance of the equatorial regions,” Pickles said. “So what the Peters map does, it will give students a better sense of the relative importance of the global south.”
Pickles said the Mercator map was used politically by many newspapers and magazines and probably in schools to focus the attention of the students along the larger land masses.
Changing maps, however, has not just been a recent issue, Pickles said.
