Which of the following is an effective strategy to reduce children's gender stereotyping and gender-role conformity?

Open discussion about gender bias is the most effective strategy to reduce gender stereotyping and gender-role conformity. By making children aware of biases and stereotypes, educators help them critically examine and challenge these assumptions. The other options - emphasizing gender-specific roles, gender-segregated play groups, and gender-segregated seating - actually reinforce stereotypes and conformity rather than reducing them.
