This phenomenon is rooted in societal biases and stereotypes that have historically attributed certain skills and abilities to specific genders. Such stereotypes can lead to unconscious bias among teachers, parents, and society as a whole, resulting in girls being underestimated or undervalued in their mathematical abilities. Research has shown that these biases can affect girls' confidence and opportunities in mathematics education, even when they are capable of performing well. Addressing and challenging these gendered constructs is essential for promoting gender equity in mathematics education.
