Finding meaning in quadratic equations through a physical context: falling objects motion

This paper presents the results of implementation a design focused on resignification parameters quadratic equation (parabolas) through context physical phenomenon. was based an epistemology practices framed in principles cognitive and social constructivism, particularly socioepistemological theory mathematics education, also model guided discovery. Based students' arguments, evidence is shown such way that relationships between algebraic graphical expressions were established. It identified experiences, as well context, determining elements for success resolution design.
