In "The Color of Water", why did Ruth send her black children to Jewish public school? Why did Ruth send her black chrildren to Jewish public school?

First,
let's talk about your question.  There
are no Jewish public schools in the United States. If a
school is Jewish, it
must be a private school.  If you are talking about a public school with a

large population of Jewish children, that is another matter entirely.

The
author says that his mother sent the children to "white schools
to get the best
education" (McBride 22). Later on in the book, the author
states that she sent them to
"predominantly Jewish public schools" (67). The
author explains that his mother felt
Jewish parents cared about scholastic
success and raised their children accordingly. Since
education was a priority
for Jewish parents, they often settled in the same neighborhoods.  This
gave
them a kind of "majority role" in their neighborhood public schools and made
it
easier for them to be involved in their children's education.  There is
good evidence to show
that parents who are actively involved in their
children's education have children who are more
successful.  Ruth was aware
of this, and knew that her children would be most successful in an

environment in which there were more interested parents and more successful children. 
There is
a kind of ripple effect in a school, so that success breeds success
for everyone, and sometimes
failure breeds failure in the same way.  Ruth was
perfectly aware of this, and even though she
cut herself off from the
religious aspect of Judaism, she maintained the cultural goal of
academic
success.

I hope this helps!
