Solving arithmetic word problems. An analysis of Spanish textbooks / Resolución de problemas aritméticos verbales. Un análisis de los libros de texto españoles

Abstract

Abstract This study analyses whether the primary school mathematics textbooks from two Spanish publishers show a varied instructional diet of addition and multiplication problems at different levels of complexity. To do so, it analyses the problems in all the primary grades by the publishers Santillana and SM according to two levels of complexity: (a) procedural (number of steps needed to solve the problem); and (b) semantic/mathematical (addition or multiplication structures, with their different subtypes). The results show that: (a) these problems are so simple that the books themselves cannot be regarded as a sufficient tool to teach students to solve the more complex problems; and (b) if we compare them with previous studies, the design of the problems has hardly changed in 10 years. These results show that the variety of problems in books should be expanded both procedurally and semantically/mathematically, and teachers should be given assistance to compensate for these shortcomings when using these textbooks in class.
