Final answer:
Ruby's mother wanted her to attend a new school likely due to the desire for a better and equal education, as advocated by the Brown vs. the Board of Education decision, which was aimed at ending school segregation and ensuring equality.
Step-by-step explanation:
Ruby's mother likely wanted her to go to a new school to ensure that Ruby would receive a better education, as was the right guaranteed post the Brown vs. the Board of Education Supreme Court decision. This case aimed to provide equal educational opportunities for everyone, irrespective of race, by integrating schools. With the integration of schools, parents would have had hopes that their children would get access to more resources and a higher quality of education, which had historically been denied to Black students due to segregation.
The goal was not specifically to be among a lot of Black students or White students but to be in an environment that provided a better and equal educational experience, which often meant being in integrated schools. The decision also addressed the psychological impacts of segregation which included feelings of inferiority among Black children, as demonstrated by the Clarks' research in the 'doll test.' While some Black communities valued the nurturing aspect of their schools, the overall desire for equal opportunity was a driving factor in seeking a new school for their children.
