Pedemonte B. The algebraic manipulator of Alnuset: a tool to prove. In: CERME6 - Sixth Conference of European Research in Mathematics Education (Lyon, France, 28 January - 1 February 2009 2009). Proceedings, pp. 1 - 10. ERME, 2009.
This report is devoted to analyzing the influence of an algebraic system, the Algebraic Manipulator of ALNUSET on students' construction of proof in proving equivalence among expressions. Results of an experiment, carried out with students at the second year of Upper Secondary school, are presented to show in which way this manipulator can be used in the educational practice to enhance the teaching and learning of algebraic proof.
