Learning beginning algebra with spreadsheets in a computer intensive environment

Solving a contextual problem with the spreadsheet as an environment for algebraic thinking development

“…Moreover, as noted by Haspekian (2005) a spreadsheet also allows an algebraic organization of apparently arithmetical solutions and this kind of hybridism, where arithmetic and algebra naturally cohabit, becomes an educational option that may help students in moving from arithmetic to algebra (Kieran, 1996). Spreadsheets can act as a bridge between arithmetic and algebra by helping students generalize patterns, develop an understanding of variable, facilitate transformation of algebraic expressions, and provide a space to explore equations (Tabach et al, 2008). In addition spreadsheets allow students to focus on the mathematical reasoning by freeing them from the burden of calculations and algebraic manipulations (Ozgun-Koca, 2000).…”

Actuaciones de alumnos instruidos en la resolución algebraica de problemas en la hoja de cálculo y su relación con la competencia en el método cartesiano

“…Plantear un método algebraico de resolución de problemas en la hoja de cálculo se apoya en que numerosos estudios han puesto de manifiesto que el empleo de este entorno informático puede tener un papel destacado en los primeros momentos de la enseñanza del álgebra (Dettori, Garuti y Lemut, 2001;Tabach y Friedlander, 2004;Tabach, Hershkowitz y Arcavi, 2008;Wilson, Ainley y Bills, 2005).…”
