Trayectorias de control y co-variación de variables como expresión del cambio cognitivo en la solución de un problema

This research characterizes paths and trajectories followed by 136 university
subjects while solving a physical-mathematical problem of proportionality,
proposed through an interactive software, in order to analyze the intra- and
inter-subject variability, regarding the type of control variables and co-variation
used. Five types of control variables (a: No Control, b: Simple Control, c: Simple
Control greater than two attempts, d: Alternating Control and e: Controlled
Change) and four of co-variation (f: No co-variation, g: Increasing co-variation,
h: Decreasing co-variation and i: Mixed co-variation) were evidenced. The
microgenetic method with qualitative and quantitative measures was used. The
various paths and trajectories witness cognitive change in solving the problem.
It is concluded that there is a significant variability in the procedures used by
the population, as well as significant differences with respect to trajectories with
consolidated control or co-variation compared to those that did not have it,
also among those with paths with intermittence and without intermittence.
