| Sumario: | Over the last decades, several representation systems have been used to improve the learning of the manipulations of algebraic expressions. In addition, the introduction of new technologies in Mathematical Education allowed the simultaneous use of different representation systems. Some of these applications use a physical representation of the equation, as for example, balances or areas, to give some meaning to the algebraic manipulations. However, the use of real models has the difficulty of translating the actions performed in the physical environment to the algebraic language. In this work we analyse the effect of using the program DragonBox Algebra© in a school context. In particular, we study the students’ competence in solving equations when the students return to the world of algebra. We compared the results of two tests taken by the students before and after an intervention in an Initial Professional Qualification Program group. The tests consisted of a set of equations with one or more letters. The results show a significant increase in the post test scores. |
