Puesto que los alumnos razonan y resuelven mejor los problemas ‘auténticos’, contextualizados en situaciones que les resultan cotidianas, y que los alumnos de Singapur han demostrado en diferentes evaluaciones internacionales ser más hábiles en resolución de problemas que los españoles, en este estudio se compara el nivel de autenticidad de los problemas incluidos en los libros de Primaria de las editoriales más frecuentemente utilizadas en ambos países. Los resultados muestran los libros de Singapur contienen problemas con un mayor grado de autenticidad que los españoles en todos los niveles escolares, proporcionando a los alumnos mejores oportunidades para aprender a resolver problemas a través del razonamiento.; [EN]The nature of the arithmetic word problems found in maths textbooks influences the way students develop their ability to solve them, as teachers use the books in their classes quite frequently. Given that students are better able to reason through and solve authentic problems that are contextualized in situations familiar to them, and that different international assessments have shown the students in Singapore to be more skilled at problem-solving than their Spanish counterparts, this study compares the level of authenticity of the problems included in the primary school textbooks from the most frequently used publishers in both countries. The results show that the books from Singapore contain problems with a higher degree of authenticity than the Spanish textbooks at all school levels, thus providing students with better opportunities to learn how to solve problems through reasoning. 2021-02-15T00:00:00Z http://hdl.handle.net/10366/154449 [EN]Singaporean children are the best performers on international achievement tests in mathematics (i.e. the TIMSS). Their excellent results could be due at least partly to certain characteristics of the textbooks used there (Oates 2014). Therefore, these materials could be taken as a good benchmark to describe and evaluate aspects of the textbooks of other regions that could be improved. For this reason, the word problem-solving approaches proposed by primary education math textbooks from Spain were compared with those from Singapore based on the presence of the problem-solving steps that are most characteristic of a genuine word problem-solving approach. The results show that the Singaporean textbooks include much more reasoning than the Spanish textbooks, while they include fewer problem-solving steps related to strategies and checking. We conclude that Singaporean textbooks provide better scaffolding for high-quality learning of word problem solving than Spanish textbooks. 2019-12-01T00:00:00Z
