Final answer:
The controversy over the curriculum taught in public schools, including the Common Core State Standards and funding disparities, is the subject of this question.
Step-by-step explanation:
The subject of this question is Education and it specifically focuses on the controversy surrounding the curriculum taught in public schools.
One key source of controversy is the Common Core State Standards, which have faced criticism mainly regarding the assessment process and the high stakes involved. The national teacher's unions initially agreed to the standards, but have since become vocal critics.
Another factor contributing to controversy is the disparity in funding per student throughout the country, with schools in well-to-do communities often having more resources than those in less affluent areas.
