The Tampa Bay Times published this article in March 2014 about math textbooks not aligning to Common Core standards.
As with much of Common Core, the issue is - what's the rush? Meaning, many of these textbooks do not fully (or even by half) align with CCSS because they had to rush into production in order to get them out for consideration. A lot of this "alignment" is WILL have to happen at the school/district level.
To understand, there is no "CC seal of approval" - any publisher can say their books are aligned and unless a researcher or school district official thoroughly checks, there's no one to check publishers' claims.
Now, there's concern that a darker unreality is on the cover of
textbooks in order to sell the books to adults: seals that say the texts
are aligned to the new Common Core standards.
According to a study by a University of Southern California
researcher, textbooks marketed as being in step with the Common Core and
currently used in Tampa Bay classrooms fail to capture key concepts of
the higher-level standards that have been adopted by Florida and most
Because of the time and money involved in overhauling a textbook,
there are few incentives for publishers to make significant changes from
one edition to the next, Polikoff says. "One of my inclinations is they
don't want to make big revisions. This is what a typical textbook has looked like for a long time."
In all, he analyzed four textbooks approved by the Florida Department
of Education to teach the Common Core math standards to fourth-grade
He found that Common Core content is left out of textbooks, the books
spend pages on the wrong content, and they fail to reach the higher
levels of cognitive demand that separate the new standards from the old.
For instance, the Common Core calls for 40 percent of a
fourth-grader's time to be spent on advanced problem-solving such as
demonstrating, generalizing and analyzing. But the textbooks require
students to do so only 7 to 12 percent of the time, instead requiring
them to memorize or do rote drills.
"The simple fact is that, for a lot of teachers, particularly
elementary teachers, if something isn't in a textbook, it doesn't get
taught," Polikoff says.
As well, another researcher, William Schmidt from Michigan State University, did his own analysis.
William Schmidt, the co-director of the education policy center at
Michigan State University, conducted his own analysis of dozens of
textbooks covering first through ninth grades and used by about 60
percent of students nationwide.
At a recent seminar hosted by the Education Writers Association in
Los Angeles, Schmidt said that "page by page, paragraph by paragraph,"
many textbooks were identical to previous editions.
Schmidt does support CC but says there are really only two math books that currently align with CC (he declined to name them).
These textbooks claim they are aligned to the Common Core standards.
Florida approved them for use in local schools. But new research
suggests there's only a modest correlation between the texts and the
standards they purport to cover.
