MULTIPLY BY SUMMING: AN EXPERIENCE WITH SENIOR HIGH SCHOOL STUDENTS

In this article we report an experience carried out with senior high school students based on Socioepistemology and adopting didactic engineering as research methodology. The purpose was to generate a particular environment that would favor the emergence of the logarithmic using manageable materials, rescuing primordial arguments by Stiffer, Napier y Briggs. The analysis of the students' individual and collective argumentations which arise when discovering and using the rule of multiply by summing as a tool to facilitate operations in order to construct more charts as well as the game's general chart, demonstrates an approach to the covariation and the logarithmic properties.
