The Textbook Trap » Errors in science textbooks
A 1998 study of middle school physical science textbooks revealed thousands of errors, forcing researchers to conclude that “none of the 12 most popular middle-school physical science texts was acceptable”.1
And these errors were not necessarily typographical; they involved scientific inaccuracy and imprecision. In 2000, Project 2061, a reform initiative for the teaching of science and math in grades K-12, evaluated leading science and mathematics textbooks. These findings concluded that “most of the texts have serious weaknesses” and “not one was rated highly” (American Association for the Advancement of Science, 2000 Annual Report).
But it is not just the science and math texts that have weaknesses; history books also have problems.
