Matt Barnum, writing in Chalkbeat, describes the mixed reactions of high school students to Common Core math.

Some hated it.

Some liked it.

Some found it confusing.

The Common Core standards were supposed to get students to understand math more deeply. For some California high school students, it didn’t work out that way.

“I like working in the old books, because they actually explain it to me,” one said. “Do you want me to learn it? Or do you want me to stare at the problem?”

That’s one response from a survey of students who experienced the shift to the new standards in their math and English classes. The study is quite limited, emerging from interviews from just 54 high-achieving seniors. But it gets at something often overlooked in the political controversy that would eventually surround the standards, which most states adopted in 2010: what it felt like for students to see their classrooms change.

Some of the student’s responses, published last month in a peer-reviewed academic journal, may be surprising. Many blamed the Common Core for encouraging more group work — something they almost universally disliked. In some schools, though, the students appreciated what they perceived as a move away from teacher-led instruction.
