SALAZAR SOLORZANO, Lorena. Design of tasks from the modification of problems in textbooks of Mathematics. Paradígma [online]. 2014, vol.35, n.1, pp.55-77. ISSN 1011-2251.

This paper presents the results of a classroom experience, which aims to investigate the effect produced by the incorporation of tasks designed from modification problems proposed in text books, in the understanding and academic performance of future mathematics teachers. The experiment was conducted in a real analysis course in the subject of continuous functions, which is part of the program Mathematics Teaching at the University of Costa Rica. It was observed some positive evidence, such as better understanding of word problems and theorems, increased understanding of formal testing solutions, numerical increase in the evaluation of the topic and greater competence reflection on mathematics.

Palabras clave : problem posing; problem solving; task design; mathematics education.
