La llegada de familias inmigrantes a nuestro país ha conllevado un notable incremento de inmigrantes o hijos de inmigrantes en las escuelas, lo que las han convertido en espacios multiculturales. El concepto de cultura podría convertirse en el andamiaje sobre el que se estructuran discriminaciones, prejuicios y estereotipos hacia grupos e individuos.
