This hidden curriculum of lessons has survived in the daily functioning of the classroom where teachers are unaware of their own biased teaching behaviors for the sake of their diligent duties as teachers. These teachers apply their teaching according to how they obtained it. At younger ages, the learning environment is feminine as adult women outnumber male teachers. Teachers present curriculum materials that contain gender stereotypical behaviors that students internalize and exhibit these behaviors which in turn guide their behaviors and preferences. In these institutions, teachers receive little training in combating gender stereotypes of themselves and others and, as a result, often model, reinforce, and lay the foundation for gender role differentiation among their faculty.
