This paper examines the biological differences found in the brains of boys and girls, drawing on neurological research and social observation to assess their significance. Beginning with foundational findings about the hypothalamus and cerebral cortex, the paper reviews studies on how brain differences may or may not translate into behavioral differences. It then considers the implications for education, weighing arguments for single-sex schooling against integrated approaches. The paper concludes that while biological gender differences are scientifically supported, their effect on behavior is still debated, and the priority should be using this knowledge to optimize educational outcomes for all children.
The obvious biological differences between men and women have long inspired a search for corresponding mental differences. Much of the oppression suffered by women in the traditionally patriarchal world of business and society has been blamed on the preconceived notion that women were somehow inferior to men in certain areas. The rise of feminism challenged and largely negated such assumptions. However, recent research has brought to light new information regarding biological differences in the brains of girls and boys that has reignited the debate.
New research into brain differences has been ongoing since the 1960s (Gabriel 2001). The finding that the preoptic area within the hypothalamus was larger in males than in females prompted further research and additional discoveries of this kind. These investigations have also been made easier by advances in imaging technology (Gabriel 2001).
One significant study was conducted in 1999 by Dr. Gabrielle de Courten-Myers of the University Medical Center (Gabriel 2001). The neurologist found a larger number of neurons in the cerebral cortex of men, while women were found to have more neuropil, the dense network of nerve fibers that facilitates cell-to-cell communication.
It thus appears established that biological differences exist in the brains of girls and boys. However, the true effect of these differences on behavior remains the subject of current debate. While the data supporting physical differences appear to be substantiated by various tests, the behavioral implications are another matter entirely. Some researchers still hold that there are no meaningful differences between the brains of boys and girls, but the focus of the debate is gradually shifting. The question has become not whether differences exist — science appears to have substantiated that they do — but whether such differences should be given substantial weight in social structures such as education. Dr. de Courten-Myers, for example, holds that differences in brain function between boys and girls are likely, but she admits that the precise nature of the connection between morphology and function is difficult to determine (Gabriel 2001).
According to a PR Newswire article (2000), attempting to force boys and girls into an androgynous learning environment may be harmful to their developing identities as men and women. The reason appears to be the inherent biological differences that exist in the brain. Boys and girls exhibit differences that manifest from birth, and these differences need to be acknowledged, according to the article.
Experimental observation also indicates marked differences between boys and girls (Palar 1996). Boys appear naturally more robust, energetic, and noisy than girls. A study was therefore conducted by a local school district to determine the best course of action to meet the needs of each gender.
Palar cites a 1992 AAUW report claiming that boys and girls enter schools with roughly the same abilities. However, the report sides with social influence, arguing that because boys receive more positive attention than girls in the classroom, girls become less confident in technical subject matter and are placed at a disadvantage once they leave school. It therefore appears that boys and girls do not necessarily learn differently, but are treated differently in the classroom, which ultimately influences their academic ability.

Of primary importance is keeping up with the research on gender and brain difference. Teachers should be educated and well versed in the field, and able to implement any new findings that may come to light. Policymakers and educators alike must engage with this growing body of evidence thoughtfully. Only if differences are acknowledged and honored can we hope to build a truly integrated society, starting with our children.
