This study examined 1st and 2nd grade mathematics textbooks, studying books, and
teachers guidebooks according to 2015 revised national elementary school curriculum
to determine the appropriateness for working with students with mathematics
difficulties. To do this, critical features which Bryant and her colleagues (2008)
created based on literatures related to mathematics difficulties and disabilities were
applied. First, results showed that the features were not fully incorporated. Second,
the mathematics textbooks, studying books, and teachers guidebooks reflected the low
level of the features related to mathematics content, while they incorporated the
middle level of features related to mathematics procedures. Third, all mathematics
domains included the middle level of features. Given the results, the implications on
creating mathematics textbooks were discussed.
