This cross-national European comparison examined gender representation and stereotypes in mathematics and language textbooks from Germany, Italy, Lithuania, the Netherlands and Romania. The results showed that female characters were numerically underrepresented. Female characters were also less often a main character or individually portrayed compared to male characters, but not proportionally to the overall lower number of female characters. Characters in occupational roles were less often female than male, whereas among characters with gender non-conform characteristics, these were more often female than male in some textbooks. There was no sexual diversity among characters. The differences in gender representation are found within each country, but gender differences were smaller in more gender-egalitarian countries. If textbooks are to offer the same learning benefits to both boys and girls, students should be equally represented in a diversity of roles and occupations.
