Meredith Broussard, a professor of data journalism at Temple University, was helping her son with his homework, and she made a discovery: he could not find “the right answer” to homework questions unless they were in the textbook. But on further investigation, she learned that the public schools of Philadelphia don’t have a textbook budget. So not only do students not have access to the answers that will be on the test, they don’t have a chance to succeed.

In an article that she wrote for “The Atlantic,” she concluded that after $1 billion in state budget cuts, the Philadelphia public schools had a budget of $0 for textbooks. These students don’t have a chance.
